The complex multi-gear, multi-species tropical fisheries in developing countries are poorly understood and characterising the landings from these fisheries is often impossible using conventional approaches. A rapid assessment method for characterising landings at fish markets, using an index of abundance and estimated weight within taxonomic groups, is described. This approach was developed for contexts where there are no detailed data collection protocols, and where consistent data collection across a wide range of fisheries types and geographic areas is required, regardless of the size of the site and scale of the landings. This methodology, which was demonstrated at seven fish landing sites/fish markets in southern Indonesia between July 2008 and January 2011, provides a rapid assessment of the abundance and diversity in the wild catch over a wide variety of taxonomic groups. The approach has wider application for species-rich fisheries in developing countries where there is an urgent need for better data collection protocols, monitoring future changes in market demographics, and evaluating health of fisheries.

Introduction

Indonesian fisheries are among the largest and most productive worldwide, and are critical to the nation's economic development and in providing food resources to millions of people. In 2004, production from marine capture fisheries in Indonesia was approximated at 4.5 million tonnes with an estimated gross value of US $3.13 million [1] . The total marine capture fisheries production in Indonesia increased to 5.4 million tonnes in 2010 [2] . The high level of employment, which in 2003 was estimated at 3.3 million people directly employed in marine capture fisheries [1] , is an important indicator of the value of fisheries to Indonesia. This places Indonesian marine capture fisheries among the top five worldwide in terms of fisheries production. The level of fishing effort in Indonesia is also increasing rapidly, with the number of motorised marine vessels increasing from an estimated 348,425 in 2007 to 390,770 in 2009 [3] .

The majority of Indonesia's capture fisheries are considered to be fully or overexploited despite the fact that marine capture production in Indonesia is increasing annually [4] . One of the greatest problems facing Indonesia's Ministry of Marine Affairs and Fisheries is the quality of fishery statistics available. Since Indonesia's fisheries are both multi-gear and multi-species fisheries operating over 80,000 km of coastline, it would not be feasible to collected catch statistics from all catches. As a result, catch statistics are obtained by averaging daily catch from a small subset of vessels and multiplying by the number of vessels and number of fishing days to obtain annual catches [5] . This method has many obvious weaknesses, with a major problem being that illegal, unregulated and unreported (IUU) catches are not accounted for in these statistics [3] , [6] , [7] .

Catches of many small-scale fisheries are often overlooked, but the cumulative catches from this sector can be very high, particularly in biologically rich and densely populated countries such as Indonesia. In developing countries these small scale-fisheries are also extremely important to the local economy and account for a substantial proportion of the overall capture production [8] , [9] . Despite this, there are very few studies of multi-gear, multi-species fisheries in tropical regions of the world [10] , [11] , [12] , hindering the ability to develop adequate management strategies for such areas. [12] undertook comprehensive surveys of the main fish market at Manado, North Sulawesi (Indonesia), which was dominated by small-scale coral reef fisheries. These market surveys recorded species-level composition data where possible and allocated fishes into 10 cm size-classes. This approach allows for an accurate assessment of the landings at this particular market, but obtaining this level of information at much larger and demographically more complex markets would not be possible. There is a need for a more rapid, standardised method of collecting landings information from fish markets or landing sites in tropical regions with diverse fisheries.

In this paper, we present a new Rapid Assessment Protocol: Rapid Fisheries Assessment by Market Survey (RFAMS) for assessing catch composition at fish landing sites and markets in the circumstances where no detailed data collection protocols exist. Present methods of recording catch composition data in developed and small-scale fisheries are not suitable for countries such as Indonesia which have very large, complex, multi-gear and multi-species fisheries. We emphasise the importance of collecting accurate taxonomic information, albeit not to species level, to enable biodiversity to be assessed. The major aim of this new data collection methodology is to provide data-poor regions with a tool for being able to efficiently characterise the landings at different fish landing sites and markets regardless of their physical size and the scale of the landings. This method is considered to be widely applicable to fisheries researchers and managers in data-poor regions where there is no existing, or minimal formalised, market data collection protocols. The data collected using this approach will also provide important benchmarks for monitoring future changes in these fisheries.

1. Ethics Statement

All marine life examined in this study were landed from small-scale fisheries in Indonesia and were already dead upon inspection. Permission to undertake surveys in Indonesia was granted by the Research Centre for Fisheries Management and Conservation in Jakarta as part of a collaborative project funded by the Australian Centre for International Agricultural Research (project code FIS2006\142).

2. Study Area

Seven fish landing sites were surveyed across five provinces in southern Indonesia, i.e. West Java (Pelabuhanratu), Central Java (Cilacap and Sadeng), East Java (Muncar and Pacitan), Bali (Kedonganan) and West Nusa Tenggara (Tanjung Luar in Lombok) ( Fig. 1 ). Three of these sites, Muncar, Pacitan and Sadeng, were surveyed 3 or 4 times, while the remaining sites were surveyed between 6 and 9 times during the study. Across these 7 sites, a total of 60 daily surveys were completed between July 2008 and January 2011.

Pelabuhanratu is a medium-sized port on the south coast of West Java with a diverse range of fisheries operating, from bagans (light traps) to oceanic longlining. Cilacap is a large port on the south coast of Central Java which is dominated by a tuna longline fishery. Sadeng is a small port on the south coast of Central Java, east of Cilacap, with only small landings from several different fisheries. Pacitan is a small port on the southwest coast of East Java which is dominated by a trolling fishery targeting small tuna. Muncar is a large port on the east coast of East Java which is dominated by a purse-seine fishery for lemuru (sardines). Kedonganan is a medium to small landing site at Jimbaran Bay in southern Bali which has a diverse range of fisheries targeting a variety of fish and invertebrate groups. Tanjung Luar is a medium-sized landing site on the east coast of Lombok which is best known for its longline fishery targeting large sharks and large mobulid bycatch from the tuna gillnet fisheries.

3. The Rapid Fisheries Assessment by Market Survey (RFAMS) methodology

The data sheets used for RFAMS can be found in Datasheet S1 . The initial information recorded is the fish market (or landing site/port), data recorder (person or group), date and time of survey (e.g. 7:00–9:00 am). The total estimated weight of the landings was classified into one of five categories, i.e. <100 kg, 100–500 kg, 500 kg to 1 tonne, 1–10 tonnes and>10 tonnes. Where possible, a total estimated weight was also provided calculated by summing the estimated weights in each of the taxonomic categories (see below). Where possible, the fleet size was recorded by determining the approximate number of boats in each of six categories based on boat size (note GT = gross tonnes): <5 GT, 5–10 GT, 10–30 GT,>30 GT, small with outboards and small without outboards.

To capture data on the broad habitats being fished, the estimated percentage contribution of the catches in each predetermined bathome (depth-related habitat zone) was also recorded. Generalised bathomes were used in this study: 1) freshwater; 2) estuarine; 3) coastal; 4) coral reef; 5) shelf demersal; 6) slope demersal; 7) inshore pelagic; 8) oceanic; 9) aquaculture; 10) intertidal. Likewise, to capture data on the various fisheries involved in the landings, the estimated percentage contribution of the catches in each predetermined fishing method was also recorded. The predetermined fishing methods used for Indonesia in this study were: 1) cast net; 2) diver/spear; 3) dredge; 4) gillnet; 5) handline; 6) longline; 7) traps; 8) purse seine; 9) tidal trap; 10) trawl; 11) beach seine; 12) bagan (light trap); 13) by hand; 14) trammel net; 15) hand net; 16) dynamite/poisoning.

Catch composition of the landings was divided into 6 major taxonomic groupings: Cephalopods (e.g. squid, octopus), Other Molluscs (e.g. bivalves, clams), Crustaceans (e.g. prawns, crayfish and crabs), Other (e.g. marine mammals, sea turtles, algae), Elasmobranchs (e.g. sharks, rays) and Teleosts (bony fishes). For each of these major groupings, their percentage contribution to the landings (calculated from estimated weights of each of the taxonomic categories for all groups) and an estimate of the number of species observed was recorded.

Within each of the major taxonomic groupings, catch information was recorded on a family-level basis (e.g. Octopodidae, Penaeidae), except in a few cases where broader categories were used due to difficulties in accurate family-level identification during rapid surveys (e.g. squids, algae) (see Appendix S1 ). In the case of elasmobranchs, catch information was recorded at a species level due to the detailed knowledge available on this group from the Indonesian fish markets surveyed in this study [13] . In the case of the most abundant or most diverse teleost families, catch data was also recorded for the major genera or species groups, i.e. Carangidae ( Caranx/Carangoides , Decapterus , Scomberoides , other carangids), Scombridae ( Thunnus/Euthynnus , Katsuwonus/Sarda , Scomberomorus/Acanthocybium , other scombrids). The predetermined taxonomic categories provided in the data sheets ( Datasheet S1 ) were based on surveys undertaken in Indonesia prior to this study (e.g. see [13] ) as well as general knowledge of the fish groups exploited in South-east Asia. Blank spaces are also provided for other families encountered which are not listed.

Within each of the taxonomic categories, the data recorded were: an index of abundance, bathome, fishing method and estimated weight. An index of abundance (0–11) was recorded based on a log scale: 0 = 0; 1 = 1; 2 = 2–3; 3 = 4–9; 4 = 10–27; 5 = 28–81; 6 = 82–251; 7 = 250–749; 8 = 750–1999; 9 = 2000–5999; 10 = 6000–19,999; 11 = >20,000 individuals. A log scale index was used as it provides a good indication of abundance and is simple and quick to record which is important in fish markets where large numbers of some fish groups are landed. The corresponding number for the relevant bathome and fishing method for each taxonomic category was recorded (see above). For example, tuna caught by pelagic longlines would have a bathome of 8 (oceanic) and fishing method of 6 (longline). If there was multiple bathomes or fishing methods for a particular taxonomic category, only the major bathome and fishing gear was recorded. A total weight (kg) for each taxonomic category recorded was estimated. Estimation of weight was usually determined using known container weights that fish were stored in (e.g. Styrofoam boxes, cane baskets, plastic tubs and drums).

4. Multivariate analyses

The average estimated weight (kg) data for each family (or proxy taxonomic grouping, e.g. squids) at each of the 7 landing sites on each of the survey trips were used to construct a resemblance matrix, following fourth-root transformation, employing the Bray-Curtis similarity coefficient. The resulting matrix was then subjected to non-metric multidimensional scaling (nMDS) ordination and hierarchical cluster analysis using Primer v6 package [14] . A one-way Analysis of Similarities (ANOSIM) was employed to test whether the catch composition of the landings at each site were significantly different. Where significant differences exist, the magnitude of the R-statistic (0, no significant differences; 1, differences highly significant) was used to ascertain the extent to which the catch compositions of a priori groups differed. Multivariate Dispersion (MVDISP) was used to determine the degree of dispersion of each of the sites on ordination plots [15] and Similarity Percentages (SIMPER) was employed to determine the families that typified particular groups and/or contributed most to the dissimilarities between groups [16] .

The same approach was also followed to analyse the catch composition by major taxonomic group (Cephalopods, Other molluscs, Crustaceans, Other, Elasmobranchs and Teleosts), by functional group (e.g. reef fish-herbivore, pelagic rays, inshore pelagics) and by a bathome/gear combination (e.g. coral reef/handline, shelf demersal/gillnet). The ‘functional group’ category was based roughly on the ecological niche that each family best fits, e.g. surgeonfishes (Acanthuridae) into reef fish-herbivore, devilrays and manta rays (Mobulidae) into pelagic rays (see Table S1 for full list). Any bathome/gear combination used which was recorded less than 10 times were put into a single category called ‘Rare’ (see Table S2 for full list).

Results and Discussion

1. understanding dynamics of the survey sites.

In order to undertake RFAMS successfully, it was important to understand the basic dynamics of the fish landing site or market being surveyed. The most critical information is the timing and duration of landings. Preliminary information on the dynamics of the sites surveyed in this study provided key information on when to commence the survey and approximate daily duration of landings at each site. Landing sites and/or markets varied greatly not only in their catch composition but also in their dynamics. For example, Tanjung Luar is a moderately large landing site on the east coast of Lombok where catches are brought into the site directly from fishing boats or from neighbouring islands via trucks. This market commences at about 6:00 am, usually begins to slow around 8:00 am, and by 10:00 or 11:00 am is completely empty with no more activity. In contrast, the larger fishing port of Cilacap has landings commence around 8:00 am but continues off and on for most of the day, with some catches of prawns not being landed until 7:00 or 8:00 pm. Without accurate information on timing of landings at the sites being surveyed, large components of the catches can be completely missed.

The spatial dynamics at each site also need to be taken into account on each new survey trip to ensure no changes in landing sites have occurred. For example, at Cilacap, the area where catches from the trammel net fishery are landed changed multiple times between 2008 and 2011. Local fisheries officers were able to provide information where landings had been relocated. At this same location, the tuna landings from the tuna longline fishery, which often dominate landings at this site, was relocated to a different location during one survey trip due to dredging in the harbour. Without the local knowledge of these events, it could easily have been assumed no tuna were landed during that particular survey.

2. Taxonomic accuracy

One of the most important facets of RFAMS was the ability to capture good biodiversity information from the catches. Such detailed information is currently not often captured in official catch statistics for tropical fisheries with the vast majority of minor catches lumped into “other fish” categories. However, to obtain this information, a sound knowledge of the landed biota is required. Obtaining accurate species level information is not always possible in such complicated multi-species and multi-gear fisheries without prior taxonomic effort. Nonetheless, family-level or group-level taxonomic data will still provide some useful biodiversity information. Basic taxonomic training is required for users of this method and identification tools such as line drawings and regional photographic guides are useful. In this study, material for a guide to Indonesian fishes was used [17] . Line drawings and keys for the family-level groupings which can be used in Indonesia and adjacent developing countries can be found in Appendix S1 . Such guides should ideally be tailored to a specific region based on taxa likely to be encountered, but in their absence broader regional guides are still useful identification tools.

3. Acquisition of catch data

The use of the log-scale index of abundance for each taxonomic category was a rapid and simple method of recording abundance information from such large and complex catches. Capturing abundance indices is a minimum requirement when recording catch data in RFAMS. In the RFAMS conducted in Indonesia, it was also possible to record the bathome, fishing method and an estimated weight for each taxonomic category. This allows for a much more detailed assessment of catch data as it provides good information on the fisheries involved, as well as a volumetric estimate for each taxonomic category. However, it may not be possible to easily record all of these fields in much larger markets where volumes are much larger and/or harder to estimate. In these cases, an index of abundance may be the only field that can be recorded for each category.

In some instances, large quantities of fish were observed in the landing sites which also consisted of a diverse array of fish families and species. For example, the landings from trammel nets at Cilacap often contained several hundred kilos of small fishes (mostly <100 mm length). In such cases, sorting through the whole landing was not practical so the proportions of each family were obtained from a 10–20 kg subset of the catch. These proportions could then be used to estimate the total contribution of each of those families to the total landings present. Some rarer and less commercially important species may be missed in this exercise, but sub-sampling was needed to obtain useful information from these landings without sacrificing too much time examining the entire catch.

4. Important considerations of the RFAMS methodology

It is important to understand any limitations or other considerations of RFAMS so that the resulting analyses don't misinterpret the data collected or draw incorrect conclusions. The main considerations to be taken into account when using RFAMS are discussed below.

Number of data recorders required.

While some landing sites are small and can easily be surveyed by one or two people, some landing sites are far larger and more complex and require a different approach. At the landing site of Muncar, the landings are dominated by very large quantities of sardines ( lemuru ) from the purse seine fishery and are spread out over a wide area. During peak fishing times, unloading occurs very quickly to enable the next boat access to the shore and trucks transporting these landings are constantly coming and going. To be able to adequately survey the daily landings at this site, at least four data recorders are required at the various landing areas.

Standing stock.

Although some sites have a 100% turnover of landings from day to day, e.g. Tanjung Luar, Sadeng and Pacitan, other sites have a lower turnover of landings with a number of fish remaining in the market area for many days at a time, e.g. Kedonganan and Pelabuhanratu. This can present a problem if surveys are undertaken over consecutive days with some of the fish being recorded multiple times. In busy and complex fish markets, it can be difficult to discriminate freshly landed fish from ‘standing stock’ which may have been there for multiple days. It is not always possible to access this information from vendors.

Transhipment and translocation of catches.

At some landing sites, produce is transported from other nearby locations either by sea or by land. For example, at Pelabuhanratu, large quantities of bigeyes (Priacanthidae) and moon fish (Menidae) are trucked to the market from East Java. Whenever possible, these components should be recorded separately. When dealing with multi-species and multi-gear fisheries, it is very difficult to obtain accurate capture locality information for all catch brought into the landing site or market. At some locations, catches from adjacent islands are landed separately from local catches, but once brought into the market area they are all combined. In order to accurately record capture fishing areas of all of the landings, a large number of data recorders positioned at all landing areas would be required which is not feasible in most cases.

Undertaking surveys for only short periods of time.

Since surveys were conducted for short periods of time (usually 1–4 days) at each of the sites per survey trip, temporal variability in landings cannot be fully captured. Economic conditions at the time of a survey trip can influence landings. For example, at Cilacap, landings during some survey trips were much smaller than expected due to increased fuel prices which resulted in many fishers not going to sea but turning to earning income on land, e.g. agriculture. Periods of bad weather is another factor which can strongly influence the size of landings with rough sea conditions preventing smaller vessels from heading to sea to fish.

5. Multivariate analysis of the market survey data

When the average daily estimated weights of each family-level taxonomic category (e.g. Lutjanidae, Penaeidae) for each site on each trip were subjected to MDS ordination, the samples from each site formed relatively discrete groupings in most instances ( Fig. 2 ). The samples from Kedonganan and Tanjung Luar formed the tightest groupings by far which is reflected by the low MVDISP values of 0.44 and 0.69, respectively. In comparison, the samples from Pacitan, Muncar and Sadeng were the most widely dispersed, reflected by high MVDISP values (1.68–1.75). A one-way ANOSIM showed that, overall, the samples for each site differed significantly from each other ( P <0.01; R -statistic  = 0.823), and pairwise comparisons between sites showed that all sites differed significantly from each other ( P <0.05; R -statistic>0.751), except Pacitan and Sadeng which did not differ significantly ( P >0.05).

Since ANOSIM showed that the sites were significantly different from one another, SIMPER analyses on the same data set were also performed to determine the families which typified each site, and which families were most responsible for causing the difference between two sites ( Table 1 ). It should be noted that while the most abundant families are often the most typifying and distinguishing groups in this type of analysis, they also need to be consistently typifying or distinguishing across all samples (e.g. one large catch of a group on only one occasion will rarely be an important family, even if its total biomass is very large). Table 1 summarises the families which typify each site, with Scombridae (tunas), Carangidae (trevallies) and Clupeidae (sardines) the most reoccurring families, and which distinguish each site.

https://doi.org/10.1371/journal.pone.0109182.t001

Cluster analysis of the same data also shows that each of the sites differ from one another in terms of catch composition ( Fig. 3 ), but also allows a slightly better way of determining which sites are most different from others. For example, all but two of the Pacitan and Sadeng samples separate very quickly from the samples for the other sites at nearly 30% similarity, with the remaining two falling out with the Cilacap samples (reflecting the only two sampling occasions where large landings of scombrids were landed at these two sites). Pelabuhanratu and Muncar samples separate out at about 45–50% similarity from the Kedonganan and Tanjung Luar samples, which in turn separate out clearly from each other at close to 60% similarity ( Fig. 3 ).

https://doi.org/10.1371/journal.pone.0109182.g003

When the average daily estimated weights of each major taxonomic groups (e.g. Teleosts, Elasmobranchs) and also each functional group (e.g. reef fish – herbivore, inshore pelagics) for each site on each trip were subjected to MDS ordination, samples for each site formed relatively discrete groupings, particularly for functional groups. However, they were not as clearly delineated as in Fig. 2 when family-level categories were used. Although ANOSIM showed that in both cases, overall the samples for each site were significantly different, the R -statistic was much lower than when using family-level data (0.67–0.68 vs. 0.82). This suggests that obtaining more taxonomically accurate catch composition data allows for better characterisation of the markets.

When the average daily estimated weights of the landings from each of the major bathome/gear combinations (see Table S2 ) at each site on each survey trip were subjected to MDS ordination, the samples for each site formed very discrete groupings ( Fig. 4 ). The Kedonganan samples were the most tightly formed groupings (MVDISP  = 0.48), indicating that across all of the survey trips, the landings within each of the bathome/gear combinations varied the least. Tanjung Luar and Pelabuhanratu samples also were relatively tight, with MVDISP values of 0.87 and 1.07, respectively. In comparison, the Pacitan and Muncar samples were the most dispersed (MVDISP  = 1.65 and 1.66), highlighting the wide variations in landings from various fisheries recorded at these sites. ANOSIM showed that sites were very significantly different from each other ( P <0.001; R -statistic  = 0.87), which highlights that the gear used and bathomes fished are important determinants of the landings at each site. While this is to be expected, is does highlight that RFAMS is providing useful information on the multi-gear fisheries at these sites. SIMPER analysis of this data was also performed and those bathome/gear combinations that typified a site and those that distinguished between two sites are shown in Table 2 .

6. Conclusions

Despite the fact that a large proportion of the capture production of the world's fisheries comes from small-scale activities in developing countries, fisheries management in these regions are usually based on approaches and techniques from developed countries with little or no adaptation [18] . These approaches and the science supporting them have generally been applied to large stocks of few species, and are largely unsuitable for rich multispecies fisheries. A major impediment to fisheries science and management in developing countries is that fishery statistics are very difficult to collect due to a lack of well-trained staff and suitable data collection methods; this is further exacerbated as they are also typically diverse multi-gear and multi-species. In the case of Indonesia, a study commissioned by the Ministry of Fisheries [19] stated that the historical data collection methodology was obsolete and the information collected was of questionable quality. As a result, it was concluded that using this data to obtain Maximum Sustainable Yield (MSY) estimates is flawed.

The health of fisheries varies considerably throughout South-east Asia. Hence, there is an urgent need to improve catch statistics across the region. The region is too large and faunally diverse to adopt fishery independent assessment methods used elsewhere. Fish landings and markets offer a cost effective and viable data surrogate for wild catch information in developing countries, particularly those characterised by multi-gear and multi-species fisheries. RFAMS provides an important, standardised approach to characterising fish landing sites and markets in developing countries. This approach was proposed in the late 1990s during surveys of fish markets in the Philippines led by one of us (PL). The initial aim of this survey method was to determine whether it could be used to provide an indication of ecosystem and/or fishery health. For example, the species or taxonomic groups present or absent in a market are likely to partly reflect the level of fishing pressure in a particular area or fishery; for example, less commercially valuable species such as lizardfishes (Synodontidae) and ponyfishes (Leiognathidae) become increasingly more abundant in overfished demersal habitats at the expense of more valuable species such as snappers (Lutjanidae) and emperors (Lethrinidae) [20] , [21] . Similarly, heavily fished areas/regions are likely to experience a trophic shift with decreasing proportions of top order predators and increasing proportions of lower trophic levels in the catch. This method alone will not provide the necessary information to determine ecosystem health, but will provide crucial baseline information required to support more focused investigations. This pilot study was subsequently adapted and implemented herein on a much larger scale in southern Indonesia.

The RFAMS approach is important for those contexts where there are no detailed and accurate data collection protocols. During this study, RFAMS was shown to effectively characterise the landings at each of the different landing sites and/or fish markets surveyed. This method allowed for data to be collected in a consistent, standardised manner across a wide range of sites, regardless of the size of the site and the scale of the landings. The multivariate analyses highlighted the way the resulting data can be used to characterise various sites based on catch data for each taxonomic category, fishing method and bathomic combination.

One of the main challenges of this methodology is the basic taxonomic knowledge required to allocate the landings to family-level (or proxy, e.g. squids) categories. However, multivariate analysis highlighted that the sites are better characterised from one another when using landings data for family-level categories, rather than functional groups (e.g. reef fish-herbivore) or major taxonomic groups (e.g. crustaceans). Species-level data should provide a better discrimination of sites, but such detailed information would be impossible to collect due to the high species richness at most landing sites. For example, at the Kedonganan fish market, an estimated average of 88 teleost species was observed each day. The speed of turnover at sites surveyed would also hinder species-level information to be collected. There is usually a constant movement of fish reaching and leaving these sites so data needs to be collected rapidly. Identification guides are needed for users of this method to be able to assign landings into the family-level categories. A line drawing guide, which includes basic identifying features, for Indonesian fish families is now available in [17] . This guide can be used effectively in adjacent regions in South-east Asia; although the species may differ, the families present will be very similar.

This novel approach for assessing landings at fish markets provides an important capacity building tool for developing countries. If used in the proposed standardised manner, the data from RFAMS can be used to ground-truth catch statistics from particular landing sites or fish markets. For example, at Tanjung Luar, the results from RFAMS for sharks were compared with local fisheries data and provincial ( Dinas Perikanan ) data for the times they overlapped. This comparison highlighted that the local fisheries data was similar to that collected in RFAMS, but the provincial data suggest far greater volumes and appears to be erroneous. Data from these surveys also provide important baseline information which can be used as a benchmark against which future changes in catch and market demographics can be assessed.

The data collected by RFAMS is also extremely useful for future studies in the regions surveyed. The data can be explored to show where particular groups are consistently landed and in what quantities, and the fishing methods dominating particular sites, etc. This can provide important information to direct future research and to allow comparisons to be made with other regions.

7. Recommendations and future efforts

The RFAMS method is an extremely useful tool for recording catches at fish landing sites in tropical developing countries where the catches are highly diverse with many fishing types involved. However, a potentially major issue is whether a large portion of the catches is being missed for any particular reason, e.g. catches by-passing the surveyed part of the landing site, sale direct from boats prior to catches entering landing site, etc. This needs to be determined on a case by case basis depending on the landing site being surveyed. Thus, one of the critical first steps of using this method is to develop a good understanding of the dynamics of the landing site or sites being surveyed. Using this method without understanding how a landing site operates can lead to significant underestimation of landings and potentially erroneous data being collected.

Landing sites can, and typically do, vary substantially in how they operate. Two landing sites which have similar catch composition and quantities may vary in other ways which can strongly influence the data being collected. A good example is timing of the landings. One landing site may have all catches landed in a two hour period while a second could have a similar period of landing followed by a second landing/unloading of catches much later in the day. This latter landing could simply be missed if it is assumed they operate at similar times. Similarly, one landing site may have certain components of the catch (e.g. high quality tuna of certain sizes) by-passing the typical landing site area. This process needs to be understood before data collection using the RFAMS method should be commenced.

The aim of this paper was to trial a rapid data collection method for complicated fisheries in data poor regions in a standardised manner. This study has demonstrated that RFAMS can be used to collect catch composition data in a standardised manner from different landing sites in Indonesia, but how this will be adopted by fisheries managers is the next major step. For the Indonesian context, RFAMS should ideally first be used at various fish landing sites and ports within each of the provinces for short period and compared with the fisheries statistics currently captured for the same period. This would highlight discrepancies in catch information and indicate where problems may be occurring. In this context, the RFAMS could be used as a quality control mechanism which could be extremely beneficial for local fisheries authorities. The adoption of RFAMS as a useful tool for helping to quality control and potentially standardising fisheries catch data collection would be highly beneficial to Indonesia and adjacent developing nations with large complex fisheries.

Fish is an important food item that contains perfect combination of essential nutrients. The main consumable fishes in West Bengal, India are various carps and other small indigenous fishes. The objective of the study was to find out whether fish weight was a crucial factor to decide pricing and what kind of fish was beneficial for consumer from economic perspective. Thirteen markets in four districts (Kolkata, North and South 24 Parganas, Howrah) of West Bengal were surveyed to collect information about price, weight and number of vendors selling a particular fish considering 22 fish species. Subsequent statistical analyses were performed to conclude about the relationship between fish weight and price. The study indicates that pricing of every fish species does not depend solely on their weight. Weight plays important role to determine the price of few fish species such as Liza persia , Lates calcarifer , Wallago attu , Ompok pabo and Mystus tengara . But, the price of small indigenous fishes like Chanda nama , Colisa fasciata , Harpadon nehereus , Monopterus cuchia , Rhingomugil corsula , Sperata aor and Puntius puntio does not depend on the weight of individual fish. Seasonal availability, taste, consumer’s personal preference have important role to determine fish price.

A Study on Fish Diversity, Marketing and Economics in Fish Markets at Kharagpur, West Bengal, India

2021, Bharatiya krishi Anusandhan Patrica

Background: There is no previous published record regarding different fish species found in fish markets of Kharagpur town. The place is internationally renowned due to first Institute of Technology of India. Due to largest railway establishment in Kharagpur town, an influx of population is always here from different states. As such their food preference and cultural practice is different. Present survey is relevant to depicts fish preference of the town dwellers and socioeconomic status of market associated people. Methods: The study have been conducted from November 2018 to January 2020 thoroughly from 13 fish markets of Kharagpur town, West Bengal, India. Fish specimens collected, identified and preserved. Market related data have been collected from different agents, wholesaler etc. through questionnaire interviews. Result: During the study period it has been observed that 28 freshwater inland fish species; 6 freshwater exotic fish species; 19 marine fish species and 4 crustacean species are available in the Kharagpur town. Some marine molluscs like Loligo sp and Sepia sp are also sold here. There are different peoples, those belong from different districts of West Bengal and involved in fish marketing activities. Therefore, a marketing chain is being established which is interdependent to each other with a socioeconomic framework. Some measures have been highlighted towards improvement of infrastructure, hygienic conditions.

The present study was conducted to know the fish markets and marketing practices in Noakhali district for a period of 5 months; November 2014 to March, 2015. Five types of marketing channels were found in this study and most were similar in nature as marketing places were in same town and not far apart. The average cost by a retailer to trade fish was estimated at Tk. 171.6 /day. This cost included rent of trading spot, ice and local transportation. The average income of retailers in three markets was estimated at Tk. 640/day/retailer. It was found that 21% of fish supplied in the markets were carps (Indian and Exotic), 17.3% marine fish, 15.7% hilsa, 12.7% catfish, 11.3% small fish, 11% Tilapia and pungus, 7% others mix species and 4% prawn. It was reported that availability fish species in three different markets round the year ranged from 55 to 72. However, during the study period, a total of 39 fish species under 24 families were found in three markets. It was found that marine fish comprises average 33% and freshwater fish comprises average 67% in the three markets. The price of fish depends on market structure, species quality, size, weight and season. The price of galda and bagda were varied from 580±10 to 560±8 Tk. /kg, and 370±10 to 350±5 Tk. /kg respectively. The price of catla, tilapia, ilish, Thai pangus and silver carp were varied from 390±10 to 360±8 Tk. /kg, 165±5 to 150±8 Tk. /kg, 900±10 to 860±5 Tk. /kg, 140±10 to 125±5 Tk. /kg, and 160±8 to 155±5 Tk./kg, respectively. In Noakhali, around 50-180 retailers were involved in each market. It was found that the daily supply of fish in Municipal market, Datter hat and Sonapur was about 12-13, 7-8 and 2.5-3ton, respectively. Inadequate infrastructure, transportation, shortage of ice in peak season, hygienic condition and packaging facilities were cited as main constraints. It was found that 80% of the fish retailers have improved their livelihood status through fish trading to a certain degree.

This study was carried out to explore the fish marketing system and species combination in five village fish markets of Paikgachha Upazila, Bangladesh. Nine marketing channels were found in the retail markets and the shortest channel was observed when consumers directly bought fish from the producers. Most of the retailers were 30-45 years old whereas, 40% had no opportunity to receive institutional education though all of them can sign their name. In the retail markets, most of the fishes were sold without ice. Moreover, a total of 93 species were found whereas 65.59, 10.75, 9.68 and 13.98% were inland fish, marine fish, exotic fish and crustacean species, respectively. Perciformes (29.03%) outnumbered the other 11 orders and Cyprinidae was represented as dominant following 38 families. Most of the fish and shellfishes were (73.12%) available from capture fisheries and the fishes were harvested from nearby rivers of the study area. In the markets 37, 10, 8 and 6 inland species were in the least concern, near threatened, endangered and vulnerable category, respectively in the aspect of their biodiversity status in Bangladesh. Among the inland fishes, 39 species were small indigenous fish species (SIS) and demands for riverine fishes were higher than the culture fishes. The price of most of the fish and shellfishes were within 251 to 500 BDT per kg whereas, the maximum price of Tenualosa ilisha was higher than 750 BDT kg. Thirteen major constraints in the fish markets were 1 identified by the fish traders.

The fish availability and marketing system at three markets in Barisal were studied for a period of twelve months from August 2012 to July 2013. Data were collected through questionnaire interviews and focus group discussions. A total number of 64 fish species were recorded in the three markets during the study period. Among them highest amounts were ilish (39%) and lowest amounts were Thai koi (2%). About 85% of the fishes were brought from different rivers and ponds of the Barisal region and only 15% from Mymensingh, Jessor, Satkhira and from India (major carps). The marketing channel from fishermen/fish farmer to consumers passes through a number of intermediaries such as local paikers/aratdar/mahajan (local agent), wholesalers and retailers. The average gross profit of fish retailers in Port Road Bazar, Natun Bazar and Lakhutia Bazar were estimated as BDT 950/day, BDT 750/day and BDT 400/day (1 US$=78 BDT), respectively. Lack of storage facilities, poor supply of ice, exploitation by middlemen, lack of money and infrastructure were the common constraints of the fish marketing.

The current study is focused on Sundarbans's fish marketing aspects, taking into account some inefficiencies, economic characteristics of marketing activities, and existing marketing systems. In Shyamnagar, a huge number of people depend on fish distribution and marketing networks for their livelihoods. Fish marketing is virtually entirely a private sector domain. Local merchants, agents/suppliers, wholesalers, and retailers are just a few of the intermediaries in the market chains that connect producers with the consumers. The daily supply of fish at the Shyamnagar upazila fish Market, kalbari fish market and Nwabeki fish market in Shyamnagar was estimated to be 15-16, 18-19 and 12-13 tons, respectively, based on a sample of 60 dealers from the three major markets in the upazila. Almost all of the fish (80%) is imported from Sundarbans and the surrounding areas and just 20% of the seafood is produced locally. According to estimates, carps make up 40% of the fish sold in marketplaces. 13% hilsa, 10% catfish, 7% native small fish, 10% prawns and shrimp, 7% tilapia, and 13% other species, including small chingri (shrimp) are the other aspects. Fish prices are influenced by market dynamics, species quality, size, and weight; it has been discovered that the cost per kilogram of carp rises with size. In three markets, every trader generated a sizable profit.

In Sylhet district, several markets and super shops are developed to continue fish related business. Therefore, the study was undertaken to discern about the inclusive market status by employing PRP tools for a period of six months from June-November 2015. The study revealed that in supply chain about 5% consumers received fish and fishery products from fish farmers directly and rest 95% fishes reached to the consumer levels through intermediaries. About 55% fish species were found as local origin and 45% came from different parts of the country. The gross margin of paiker, wholesaler and retailer was 800, 400, 1100 taka/quintal whereas net margin was 600, 320 and 960 taka/quintal, respectively. It was found that 45% consumer not prefers to take fish in fillet form and rest 55% accepted fish fillet for consumption. Major constraints of the study areas were poor drainage, transportation, icing facilities, unhygienic environment. Not only GO but also NGO should take recommended measures to overcome the existing problems of fish market in Sylhet district.

Consumers&#39; preference for fish in Tripura is facing an interesting dynamism where consumers are supplied with variety of fish species or groups. Preferences for different fish depend on the relative importance given to various attributes of fish and the utility received from it. This paper aims at finding the consumers&#39; preferences towards various consumption attributes for different fish groups in Tripura. The study was conducted for five selected fish groups across five selected consumption at-tributes for rural and urban Tripura separately. Local carps, inter-state carps, local non-carps, inter-state non-carps and small weed fish were the five major fish groups identified in fish markets of Tripura. Conjoint analysis of consumption attributes showed 34.08% (for rural Tripura) and 29.72% (for urban Tripura) of relative importance to &#39;price&#39; among five selected attributes (price, taste, availability, fresh-ness and source). &#39;Freshness of fish&#39; was found to b...

This study aimed to explore the availability of fish species, marketing channel and constraints associated with bus-stand kacha bazar fish market in order to provide recommendations for efficient fish marketing system by collecting primary data from January to December 2017. A total number of 74 fish species belonging 52 freshwater, 10 exotic, 8 marine and 4 crustacean species were available. Among them highest amounts were Ilish (35%) and lowest amounts were eel fish (2%). A majority portion of fish (70%) was supplied from rivers and ponds of the surrounding area. In this area, the majority (65%) of fish was transported through fishermen-aratdar/local paiker/Mahajan-wholesaler-retailer-consumer channel and least portion (10%) of fish were transported through fish farmer-retailer-consumer channel. Establishment of ice factory, improved electricity and water supply, construction of cold storage, modern communication system was recommended to mitigate the constraints associated with the fish market.

Fish trade, price realization and species diversification across markets in Maharashtra

Shyam, S Salim and Stanley, Lowrane and Athira, N R (2021) Fish trade, price realization and species diversification across markets in Maharashtra. International Research Journal of Agricultural Economics and Statistics, 11 (2). pp. 285-298.

The study was conducted in 22 well-structured fish markets across Maharashtra state including landing centres, retail and wholesale markets to assess the trade of commercially important fishes. The field survey was conducted during the period of August 2019- March 2020 using a structure field survey tool-Fish Market Prices (FMP). During the survey period, total of 97 species of fish fauna was traded which included 61 marine species, 21 fresh water species and 15 brackish water species. It has been observed that among the total species traded/ available across different markets of Maharashtra, inland species (Catla, Rohu, Tilapia, Asian Seabass, Common carp, Grass carp, Silver carp) were the most prominent compared to other fishes. As the theory goes the price and demand of a fish is influenced by market structure, seasonal abundance and origin of species, size and quality. Fish demand was sensitive to the price changes and their availability. The study revealed that the share of Maharashtra to total marine fish production of India has been slackening. The major reason behind the devolution of marine sector is the extreme bad weather events which adversely affected the marine fisheries during 2018. Inaddition lower catch per unit effort and non-availability of fish also resulted towards the decline of marine fish landings. The study also offers scope for the Government to intervene in the fish markets so that more fish species become available, accessible and affordable to consumers. Creation of infrastructure and provision of infrastructure seems to be the buzz word towards improved marketing efficiency.

Market Research Survey: The Complete Guide

This process involves gathering primary (self-conducted) and secondary (information already researched and made available) sources, to fully assess how a business will fare within a particular market and audience.

A market research survey is typically a source of primary information that businesses can use as part of their market research campaigns. It can also exist as a secondary source, in which case, its studies and results are published online or in a print publication.

This article will take a close look at the market research survey, so that you can use it to the optimum benefit for your business.

What Can you Achieve with Market Research?

A market research survey, as its name entails, is used for research purposes. Before we dive into all the aspects of this survey, it is apt to learn how you can use market research to your full advantage.

Market research is critical for a variety of purposes, including marketing , advertising , and branding campaigns. 

Aside from providing data-based support for these macro purposes, market research gains you invaluable insight into particular markets. For example, you may consider running a research campaign for the retail market . Market research will help you gather all the relevant information pertaining to this specific market.

Aside from retail, you can conduct market research in a number of verticals, including ecommerce , technology, real estate and many others.

There are plenty of other applications for market research. Here are some of the ways to use market research to your advantage:

• Observe data to prepare for challenges in advance
• Gauge the demand for your product or service
• Learn key market trends and staples
• Discover how your competitors are winning or losing
• Uncover your target market’s desires, preferences, aversions and thoughts

The final point is remarkably crucial for market research and for generally keeping your business afloat. And so, we’ll now dig deep into the market research survey, as this tool is especially useful for this purpose.

Defining a Market Research Survey

This tool is the most commonly used market research method — and for good reason. A market research survey allows you to gather data on your target market. Moreover, it allows businesses to do so by accessing any insights they need, as long as they form corresponding questions to their investigation.

Surveys have a far-reaching history, as they date back to ancient civilizations such as Greece and Rome. There was a surge in survey use in 1930s America, in which the government sought to understand the economic and social state of the nation.

Surveys have taken up a variety of forms, including analog forms, such as paper and mail-in formats . 

Telephone surveys were the medium of choice for survey research during the 1960s-90s. But, as technological advancements would have it, those have declined in usefulness as well.

In the present day, surveys are conducted online, particularly through the use of designated software platforms. This type of software has paved the way for easy access to primary research. 

Businesses can use online survey software and tools and to carry out all their survey research (save for creating the screener and questions). Many such tools available both allow you to build surveys along with deploying them. 

To reiterate, market research surveys are powerful tools, in that they empower businesses to ask any question they choose to better understand their market and consumer base. They also can offer key insights into competitors. 

The Components of a Market Research Survey

This tool contains two major components: the screener and the questionnaire . These form the bulk of the insights your primary research will gather.

There are also two auxiliary components to incorporate to make your survey research successful. These include the call-out (introduction) and the thank you message (conclusion).

Unlike the essential components, the need to use these will vary based on your survey deployment method and campaign. For example, an emailed survey won’t require a call-out, as the email itself serves this purpose.

A web or mobile survey, on the other hand, will need a call-out to get the attention of your respondents. 

Here is a break-down of each component, beginning with the essential elements:

• These conditions often deal with demographics, which is incredibly important, as you would need to first and foremost, survey your target market. The screener will ensure it is only your target market that takes part in the survey.
• The screener is often comprised of 2-3 questions.
• The questionnaire should ask all the necessary questions you need for a particular campaign or sub-campaign. Or, if used in a preliminary stage of your market research, they can deal with questions particularly designed to segment your target market.
• If respondents are contacted via email, the call-out is in the email’s body, inviting participants to take it, listing why it’s important, its length and what it’s used for.
• If the survey exists within a website (either as a banner, or button), the call-out is the clickable element itself (the button/banner to the survey). It too should explain the survey to respondents.
• If the survey is on a website/app, the call-out has to be visible and attractive enough for users to notice it and click on it.
• The survey often routes users to another page with a thank you message. 
• It’s important, as it lets participants know that their survey has in fact been submitted.

How to Create a Market Research Survey

Here are a few steps to take into consideration when starting on a market research survey project.

Step 1: Find a topic your business needs to learn more about.

This is particularly important if it is a topic that has little to no secondary sources. In this case, opting for a survey is the best way to learn more about it firsthand, from the people who matter most: your target market. Pay attention to any problems your business may experience, as surveys should help resolve them. 

Step 2: Consider the topic in regards to your target market

When you’ve narrowed down a problem or two, think about your target market. Do you know who constitutes it? If yes, tailor your survey topic into a subtopic that they’ll be most likely to respond to. For example, if your target market is middle-aged men who watch sports, consider whether your problem/topic will be relevant to them.

If you don’t know your target market, you should conduct some secondary research about it first, then perform market segmentation (surveys can help on this front too).

Step 3: Find the larger application of the survey campaign

Now that you’ve settled on a topic/problem and decided on whether it’s fitting for your target market, consider what the parent campaign of the survey would be. Let’s hypothetically say your topic is related to a product. Would a survey on that topic benefit a branding campaign like finding your next slogan? Would it be better suited to settle on a theme for an advertising campaign? 

Once you find the most appropriate application or macro campaign to house the survey, your market research will be organized and your survey will be better set up for success.

Step 4: Calculate your margin of error

A margin of error , in simple terms, is a measurement of how effective your survey will be. Expressed as a percentage, it measures the difference between survey results and the population value.

You need to measure this unit, as surveys represent a large group of people, but are made up of a much smaller group. Therefore, the larger the margin of error, the less accurate the opinions of the survey represent an entire population. 

Step 5: Create your survey(s)

Now that you’ve calculated the margin of error, start creating your campaign. Decide on how many surveys you would need, in regard to your margin of error and your market research needs. 

Start with a broader topic and get more specific in each question. Or, create multiple surveys focused on different but closely related subtopics to your main topic.

Send out your surveys through a trusted survey platform. 

Questions to Ask for Various Campaigns

The steps laid out above are part of a simple procedure in developing a market research survey. However, there is much more to these steps, especially that of creating the survey. 

Namely, you would need the correct set of questions, as they are the lifeblood of a survey. With so many different survey research campaigns and purposes, brainstorming questions can seem almost counterintuitive. 

To avoid information overload and any confusion that creating a survey may incite, review the below question examples. They are organized per campaign type, so you can discern which questions are most suitable for which corresponding research purpose.

Questions for Branding

Branding campaigns include efforts that build the identity of your business; this includes gathering data-backed ideas on logos, imagery, messaging and core themes surrounding your brand. You can use these when embarking on a new campaign, revamping an existing one or when you’re looking to change your brand’s reputation and style.

• Which of these brands do you know?
• What do you like most/least about this brand?
• Which idea is more important? (Use an idea behind setting up your brand’s image/style)
• Which images do you find the most inspiring? (To compare images you’ll use in your marketing/ definitive to your brand)
• What do you like about [brand]? (Can be open-ended)

Questions for Advertising

Using market research for advertising will help you obtain ideas for new advertising campaigns, testing already established campaign ideas and predicting the success of new ones.

• How would you rate the motivating power of this ad?
• Which of the following ads resonate the most with you?
• Do you remember this ad? (Name and image/video of a popular ad within your industry)
• How do you feel after watching this ad?
• What kind of use do you think this product/service produces?

Questions for Comparing Yourself with Competitors 

Studying your competitors is often associated with secondary research, but you can gain intelligence on this topic through your own survey research. The great thing about surveys is that you don’t have to focus on one competitor when managing these surveys.

• How often do you use this product/service?
• Which brand do you use for this product/service? (Include one open-ended answer).
• Which of the following products (same kind, different brand) do you find the most useful?
• What about [competitor product] would you like to see change?
• Which brand has improved your life? (Include one open-ended question).

Questions for Market Segmentation

This application is possibly the most challenging, as it involves understanding who your target market already is, then further segmenting it. We understand coming to terms with your target market first, before narrowing it any further down.

Here is how to segment your target market; you’ll notice that the questions are much more granular than the typical questions associated with each topic. (Ex: demographics typically ask for race, age, gender, income, etc).

• Demographic segmentation: Which of the following groups do you identify with most closely? (It can involve anything from music, to shopping habits, to lifestyle choices)
• Geographic segmentation: Which of the following areas do you typically spend time in to make physical purchases?
• Psychographic segmentation: How do you feel about retailers who test their products on animals?
• Behavioral segmentation: How often do you buy this kind of product?
• Sentimental segmentation: How do the following [practices, images, actions] make you feel?

Securing the Most Benefits Out of Your Market Research Survey

As we can deduce from this guide, the market research survey is a critical tool for market research . There is so much to discover about your industry, competitors and chiefly, your customers. But before making any hasty decisions, it is vital to peruse all your research documents, not just the primary research ones, such as surveys.

When you combine primary and secondary research sources, you’re setting up any business move for greater success. 

That’s because market research involves studying more than one source. It may appear daunting, but with the right tools, you can design better products, innovate on existing products, appeal to a wider audience and gain more revenue from your marketing efforts. 

Thus, pair your market research survey with other research means for a lucrative market research campaign. Knowledge truly is power.

Every September, Bob Carroll turns his driveway on Bedell Street in Deering Center into a stage for Porchfest, when bands play in front of homes throughout the neighborhood. He’s been a host for nearly all of the festival’s 10 years and credited the organizers for the hard work they’ve put in over a decade to realize their vision. This year’s festival is 12:15-5 p.m. Sunday, and more than 65 bands will play throughout the afternoon. (Carroll, 53, will host 3rd Shelf Cava.)

Porchfest is free and open to all. For more information, including a map and parking details, check the Deering Center Neighborhood Association Facebook page . This interview has been edited for length.

What is involved in being a host for Porchfest?

The date has always been ingrained. It’s always been the Sunday after Labor Day when people are mostly around, so having that in your schedule.

The actual day-of is pretty easy. Unless you’re doing acoustics. I just put out power and make it nice. People set up in my driveway. People might do that or set up on their actual porch. It’s mostly a willingness to have them use that space for an hour, maybe 45 minutes, for them to set up, and the hour that they’re playing. The bands do the brunt of the work. I put out power and some chairs. The committee does a lot of the work. They put signs out.

There’s not that much labor involved, and you have to have a willingness to have them use your space. Advertisement

Let’s say someone is coming to Porchfest for the first time. What advice would you give them about enjoying the day?

If you’re coming for a longer period of time or with your kids – it’s very kid-friendly – be prepared to meet some new people. It might be good to bring a snack because that stuff’s not really provided.

Get a map. The maps are posted, but also there’s hard copies. They’ll put it online so you can have a map on your phone. A lot of people might know two or three bands that are playing, so you can map it out.

But you don’t have to plan it out. You’re going to be surrounded by music in a six-by-six-block radius and you can just go with the flow and just have a fun day of hearing different cool music and just being around people that want to be outside and listen to music.

We try to free up the street, so there is parking at Deering High School or places that they don’t barricade off. It’s good to be prepared. You might be doing some walking. A bike is a great way too to utilize the space.

Do you usually stay at your own place? Advertisement

With two bands, it was a little harder, but I don’t usually have to go far. But if you’re a host, you still get to walk around and enjoy the music and see some of the crowds. You don’t have to stay the whole time. Most people might want to do that, but a half hour in or whatever, you can go see your friend’s band too and come back. People are really respectful about people’s property, about their space. That hasn’t been an issue for us. That’s another reason we continue to host.

Do you have a favorite Porchfest memory?

One got canceled over COVID, but the one the year after, in 2021, people just really wanted to be outside and see people and experience this. It was busy that year, and it ended up being a great day. I think people just wanted to be outside and doing stuff and seeing one another and supporting one another. I could go around and see a variety of different bands but also see a lot of people I hadn’t seen in a while due to being more around the house. That was probably my best memory, but there’s been a lot.

What do you think Porchfest has brought to the Deering Center neighborhood? How has it impacted the neighborhood identity?

It’s a strong sense of community that we look out for one another. It’s good to laugh and be social and listen to music. The music brings people together and has that sense of community. You look around, and you’re smiling and laughing, and people might be dancing, and you’re seeing kids that are now grown. If I had to sum it up, it would be a strong sense of community.
