Abstract Stevenson, T. C., Tissot, B. N., and Dierking, J. 2011. Fisher behaviour influences catch productivity and selectivity in West Hawaii's aquarium fishery. – ICES Journal of Marine Science, 68: 813–822. In 1999, marine protected areas (MPAs) were implemented along the west coast of the Big Island of Hawaii, closing ∼35% of the coastline to aquarium fishing. Catch per unit effort and total catch of the most commonly targeted fish, yellow tang (Zebrasoma flavescens), have increased since the implementation of the MPAs, yet its abundance has declined by 45% in areas open to aquarium fishing between 1999 and 2007. How effort allocation, harvesting efficiencies, and job satisfaction influence catch productivity and selectivity in West Hawaii's aquarium fishery are investigated, and how these dynamics explain the discrepancy between catch rates and relative abundance for yellow tang is discussed. Cross-sectional fisher questionnaires, semi-structured fisher interviews, and in situ and ex situ catch analyses were performed. The results indicate that fishers dive deeper when reef fish recruitment is perceived as weak, increase harvest efficiency with larger fishing teams, and intensively harvest “coral-friendly” reef fish to supply the global aquarium fish trade. Experienced fishers were less likely to exit the fishery, and job satisfaction was high despite declining fish stocks. These findings may help explain harvesting efficiencies and fleet investment, underscore the importance for evaluating fisher behaviours, and have potential management implications for other aquarium fisheries.

Full textAbstract:
Illegal fishing in small-scale fisheries is a contentious issue and resists a straightforward interpretation. Particularly, there is little knowledge regarding cooperative interactions between legal and illegal fishers and the potential effects on fisheries arising from these interactions. Taking the Chilean king crab (Lithodes santolla; common name centolla) fishery as a case study, our goal is twofold: (i) to model the effect of illegal-legal fishers’ interactions on the fishery and (ii) analyze how management and social behavior affect fishery’s outcomes. We framed the analysis of this problem within game theory combined with network theory to represent the architecture of competitive interactions. The fishers’ system was set to include registered (legal) fishers and unregistered (illegal) fishers. In the presence of unregistered fishers, legal fishers may decide to cooperate (ignoring the presence of illegal fishers) or defect, which involves becoming a “super fisher” and whitewashing the captures of illegal fishers for a gain. The utility of both players, standard fisher and super fisher depend on the strategy chosen by each of them, as well as on the presence of illegal fishers. The nodes of the network represent the legal fishers (both standard and super fishers) and the links between nodes indicate that these fishers compete for the resource, assumed to be finite and evenly distributed across space. The decision to change (or not) the adopted strategy is modeled considering that fishers are subjected to variable levels of temptation to whitewash the illegal capture and to social pressure to stop doing so. To represent the vital dynamics of the king crab, we propose a model that includes the Allee effect and a term accounting for the crab extraction. We found that the super fisher strategy leads to the decrease of the king crab population under a critical threshold as postulated in the tragedy of the commons hypothesis when there are: (i) high net extraction rates of the network composed of non-competing standard fishers, (ii) high values of the extent of the fishing season, and (iii) high density of illegal fishers. The results suggest that even in the presence of super fishers and illegal fishers, the choice of properly distributed fishing/closure cycles or setting an extraction limit per vessel can prevent the king crab population from falling below a critical threshold. This finding, although controversial, reflects the reality of this fishery that, for decades, has operated under a dynamic in which whitewashing and super fishers have become well established within the system.

Abstract Understanding the income and costs of fishing is fundamental to managing fisheries and planning interventions to improve efficiency and gender equity. Few studies offer data on fisher incomes and fuel use in small-scale fisheries (SSFs), and fewer have assessed factors influencing variation among fishers and between genders. We interviewed 235 artisanal fishers among 34 island villages in an artisanal sea cucumber fishery in Fiji. Linear mixed models were used to determine the effect of geographic and socioeconomic variables on incomes and fuel use from fishing sea cucumbers. Net income of sea cucumbers to fishers, averaging FJ$8, 171 year−1 (US$4, 494 year−1) (range: FJ$0–52,008 year−1), varied among villages and was 47% lower for women than men. On an average, 60% of fishers’ gross annual income came from fishing and selling sea cucumbers, although this proportion varied greatly even within villages. Fishers who practised gleaning, fished less often, or possessing numerous livelihood income streams, were less economically dependent on sea cucumbers. Men tended to estimate higher incomes for an average day of fishing than women when compared with their recall of last sale. Fuel use varied greatly among regions in Fiji but, overall, averaged 428 L fisher−1 year−1, and represented 28% of gross income. More economical fishing strategies by women resulted in lower fuel use than men per fishing day. Breath-hold divers used less fuel (compared to fishers using scuba) and fishers targeting deep-water species used more fuel than other fishers. A best approximation of 8000 t CO2 year−1 for the carbon footprint of the whole fishery suggests that some SSFs, such as the one studied here, can be significant contributors to greenhouse gas emissions, even compared to many large-scale fisheries globally. Reforms to the management of SSFs should consider regulations that minimize carbon emissions and reduce economic dependency on vulnerable marine resources.

Full textAbstract:
Abstract Fisher perceptions are a useful source of information that allows changes in stocks to be detected quickly and indicate the social acceptability of different management regulations. Yet traditionally, such information is rarely employed when developing management approaches. Face-to-face interviews were used to elicit recreational and commercial fishers’ perceptions of a crab (Portunus armatus) fishery in three south-western Australian estuaries. Differences in the perceived changes in the average size of crabs and fishing effort, reported concerns and supported solutions were detected among the recreational fishers utilizing the three estuaries and between recreational and commercial fishers in the Peel-Harvey Estuary. However, some common views were expressed by recreational and commercial fishers, with both sectors stating concerns over recreational fisher compliance and increased fishing and environmental pressures. While both sectors believed that reducing fishing and increasing compliance would benefit crab stocks, the mechanisms for achieving this differed. Recreational fishers favoured increasing the length of the seasonal closure, while commercial fishers favoured the introduction of a recreational shore-based fishing licence. These findings suggest that sector- and estuary-specific management rules may better facilitate the amelioration of pressures affecting individual estuaries and could contribute towards a more socially and biologically sustainable fishery.

Full textAbstract:
Catch rates reported by fishers are commonly used to understand the status of a fishery, but the reliability of fisher-reported data is affected by how they recall such information. Recalling catch may be influenced by the choice of reporting time period. Using interview data from fishers in Thailand, we investigated (1) how the time period for which fishers report their catch rates (e.g., per day or month) correlates with annual catch estimates and (2) the potential of recall bias when fishers reported multiple catch rates. We found that the annual catch estimates of fishers who reported on a shorter time period (haul, day) were significantly higher than those reported on a longer time period (month, year). This trend held true when individual fishers reported over multiple time periods, suggesting recall bias. By comparing fisher reports with external data sets, we identified that the mean across all reports was most similar to other data sources, rather than any time period. Our research has strong implications in using fishers’ knowledge for fisheries management.

Full textAbstract:
A description of the marine ecosystem that sustains fisheries production around south-eastern Australia is based on a synthesis of fisher lore of the demersal trawling sector, a review of the literature and a decade of the author’s field observations. A wide range of species are fished demersally in the South East Fishery (SEF). Until recently, managers and researchers have often implicitly assumed that many of these demersally caught species were neritic and lived in close association with the seabed. In contrast, fisher lore emphasizes the pelagic and oceanic nature of the commercial resource together with its environmentally forced variability. This paper substantially supports the views of the fishers. Up to 90%of the primary production of the SEF ecosystem may be garnered by fish foraging through extensive, but relatively sparse, oceanic phytoplankton and gelatinous zooplankton communities. Sporadically, climatic conditions cause oceanographic features to interact with shelf-break features and create ephemeral hotspots of primary production along the shelf break. Fish of the SEF take advantage of these productivity events to aggregate for feeding and breeding and their episodes of aggregation and dispersion cause the large seasonal variations in catchability observed with the shelf-break species. Implications for ecosystem management are briefly discussed.

"Spatial distribution of commercial dredge fishing effort: application to survey design and the spatial management of a patchily distributed benthic bivalve species." Marine and Freshwater Research 58, no. 8 (2007): 756. http://dx.doi.org/10.1071/mf06101.
Full textAbstract:
The patchy spatial distribution of many benthic commercial bivalve species plays an important role in determining the fishing and management strategies applied within a fishery. This study used fisher catch-return data and high resolution Vessel Monitoring System (VMS) data to determine the distribution of fishing effort within a region opened to commercial dredge fishing during the 2003 Tasmanian commercial scallop (Pecten fumatus) fishery, Australia. Fisher catch return data suggested that most (88%) of the open region was fished, however, fine-scale VMS data showed that 50% of the fishing effort occurred within 0.85% of the total area available to fishing, and 95% of the effort occurred within ~12% of the open region. The distribution of VMS inferred that the fishing effort was found to be patchy at all measured spatial scales (5 × 5 km to 250 × 250 m grid cell sizes); however, the degree of patchiness decreased with lower spatial scale cell sizes. Significant differences in the dredged benthic communities recorded within regions exposed to different concentrations of fishing intensity (heavy, moderate and low) were observed, with low and moderately fished regions containing high abundances of screwshells and their associated hermit crabs. Water depth was found to explain some of these observed differences, suggesting that the results may be the consequence of fisher behaviour over pre-existing habitat types. The observed distribution of the fishing effort and scallop beds within the Tasmanian commercial scallop, Pecten fumatus, fishery suits a closed area spatial management strategy, with the areas opened to fishing potentially being of the same scale as scallop beds (km × km).

Full textAbstract:
We compared the artisanal fisheries, in terms of catch strategies, productivity, and gross per capita income, at two reservoirs: the Barra Bonita (an eutrophic reservoir with some introduced species), and the Jurumirim (an oligotrophic reservoir, with no introduced species). Published data and structured interviews with fishers were used to evaluate fishing activity, fish biomass, and the financial performance of the fisheries. In the Barra Bonita Reservoir we analysed data from 745 fishing trips, from which 86,691.9 kg of fish were landed, with a mean CPUE of 62.4 kg/fisher-1 day-1. The main type of fish caught was tilapia (71,513.5 kg; CPUE of 51.5 kg/fisher-1 day-1), which constituted 82.5% of the biomass caught. In the Jurumirim Reservoir, we analysed data from 2,401 fishing trips, from which 25,093.6 kg of fish were landed, with a mean CPUE of 10.4 kg/fisher-1 day-1. The main type of fish caught was "traíra" (6,158.6 kg; CPUE of 2.6 kg/fisher-1 day-1), which constituted 24.5% of the biomass caught. Ordination analysis (PCA) indicated that there was a difference in composition between the fishing reservoirs and ANCOVA showed that there was a significant difference in fish production between the reservoirs. A Student's t-test showed that fishers in the Barra Bonita Reservoir had a significantly higher gross per capita income than those from the Jurumirim Reservoir. Although the Barra Bonita Reservoir has a higher fish production and the fishers earn a higher gross per capita income, we recommend the Jurumirim Reservoir as a model for artisanal fishery management because fishing activity in this reservoir is viable in the long term and such a model would promote conservation and sustainability. This contrasts with the Barra Bonita Reservoir, in which the fishery is not viable in the long term, due to environmental problems caused by artificial eutrophication and the introduction of alien species. It is also noted that in many countries, management of fisheries based on exotic species has not been viable in the long term.

SUMMARYIllegal fishing has detrimental environmental and social impacts, but these effects are difficult to mitigate without reliable estimates of fisher non-compliance. Methods used by fisheries managers to estimate illegal fishing often require indirect estimation of poaching using biological, economic or sociological indicators. This study presents a unique application of the randomized response technique (RRT) for direct estimation of non-compliance in fisheries to the Northern California recreational red abalone (Haliotis rufescens) fishery. An anonymous paper-based compliance and sociodemographic survey of recreational fishers in Sonoma and Mendocino Counties estimated 29% non-compliance with the daily take limit, 23% with the minimum size limit, 19% with licensing laws and 15% with the annual take limit. RRT results also indicated how different sociodemographic characteristics related to non-compliance. Visitors had higher non-compliance rates than local fishers for all regulations except daily take limits, which an estimated 72% of locals violated versus 18% of visitors. High fisher awareness of regulations, fisher age, income and fishing experience did not appear to influence illegal take. RRT is a powerful tool which can aid conservation managers in prioritizing action.

Full textAbstract:
Shark catches have increased worldwide, threatening the survival of several species. This study describes historical trends concerning shark consumption and commercialization by artisanal fishers in northeastern Brazil. Semi-structured questionnaires were applied and respondents pointed out that sharks used to be locally regarded as low-quality fish in the past and rejected by fish consumers, with low fisher consumption frequency. However, this has changed in recent decades, as a total of 95.4% (n=62) of the questionnaire respondents reported currently consuming shark meat, while 61.5% (n=40) highlighted its high quality. In addition, most interviewees (90.8%; n=59) reported decreasing numbers of sharks caught over time, following worldwide trends, leading to decreased fisher access to shark meat. Because of this, most respondents (70.7%, n=46) now consider it more advantageous to sell the sharks they catch than to consume them. In addition, the local commercialization of these fish is currently based on immature coastal species (<1 m). Thus, economic and biological studies on local shark populations are suggested in order to preserve local fisher culture and ensure food security for artisanal fisher communities and a long-term sustainable fishery and conservation of exploited species.

Abstract The fish market in the state of Uttar Pradesh, India, is not formally organised. Rather, it permeates from a direct fisher market to a wholesale market. Fish caught from the River Ganga are distributed through many intermediaries and are transported to farther regions like Guwahati and Kolkata in the east. The objective of the study is to assess market efficiency and, with this assessment, make recommendations that can be used to improve the livelihoods of the fishers. We accomplish this by investigating market efficiency indicators including production capacity of the area, Percent Share of Fisher in the Consumer's Money, and price stability of fish markets in different districts (including Bulandshahr, Farrukhabad, Kanpur, Fatehpur, Prayagraj and Varanasi). These are the districts that are located on the bank of the River Ganga in the state of Uttar Pradesh. The study consists of interviews with fishers, wholesalers, vendors, auctioneers, and consumers. The study examines 9 wholesalers, 9 retail markets and 1 direct fisher market. The demographic variables of fish sellers viz. age, education, caste, family size, experience and occupation are also studied. Descriptive statistics and cross-tabulation are used for nominal variables to measure and test conceptions and misconceptions of the fish market. Fish selling is carried out through fish market channels including 220 middlemen, 249 retailers, 48 wholesalers, and 72 auctioneers. Together, these individuals make up the channel structure, channel strategy, and channel performance. The high number of middlemen demonstrates that the market structure is inefficient. Higher Percent Share of Fisher in the Consumer's Money was observed for fishes like Labeo rohita (65.8%), Cirrhinus Mrigala (64%), and Labeo Calbasu (64.3%). The average Percent Share of Fisher in the Consumer's Money is 54% and shows the fishers earn little more than half of the revenue generated. The study shows that high-value fish have less price stability and low-value fish have high price stability across the fish market channel, respectively. Our investigation recommends reducing the number of market channels with the application of modern infrastructure in order to increase the quality of products received by the consumer and to increase fisher share in consumer's money.

Full textAbstract:
Spatial and temporal closures of sections of the marine environment are proposed frequently as fishery management devices, particularly when specific areas, such as spawning aggregations, can be identified. The ultimate effectiveness of spawning area closures is unknown, as spawning-related determinants of catch rate have not been studied. A simulation model, based on existing biological and fisher information, was constructed to examine the most important determinants of the spawning season catch rates using the protogynous aggregative spawner Plectropomus leopardus (Family Serranidae, Subfamily Epinephelinae) as a test case. Model output indicated that spawning season catches rose as long as catchability of spawners was equal to or greater than that of nonspawners. Greatest increases in catch were produced by fish moving from habitats inaccessible to fishers into regularly fished locations during migrations to spawning aggregations. Elevated catches were not simply dependent on the targeting of aggregations by fishers. Small-scale spatial closures around spawning aggregation sites would not be sufficient to protect the spawning stock of fish such as P. leopardus, but larger scale closures during the spawning season may be useful even when fishers are not targeting spawning aggregations.

Nigerians are high fish consumers as the per capita consumption is 14.9 kg per year and has the largest market for fish and fishery products in Africa. Artisanal fishers provide fish for large proportion of fish consumed by our teeming population. These set of fishers depend on crude gears and technology and small vessels in capturing multiple fish species. This study examined the determinants of the capacity building needs of artisanal fishers in Kogi State, Nigeria. The study used primary data. The primary data were collected using structured questionnaire. Multistage sampling technique was use to select the respondents. A total number of 292 respondents were selected for the study. Data were analyzed using frequency, percentage, mean and Binary Logistic Regression. The results showed that more than half (71.6%) of the respondents had low knowledge level and majority (87.0%) of the respondents had high capacity building needs. The educational status (p<0.10), years of experience in fishing activities (p<0.10), contacts with extension services (p<0.01) and craft type (p<0.05) are the determinants factors of capacity building needs of the artisanal fishers. The study concluded that the majority of the fisher folks had low knowledge level on fishing practices. Majority of the fisher folks had high capacity building needs. The study therefore recommends the provision of training in the areas of high capacity building needs and that there should be consideration of factors influencing the capacity building needs of artisanal fisher folks during the planning and implementation of any training programme on artisanal fisheries.

The current study was conducted to evaluate the socio-economic profile of fisher communities in Dengar beel under Melandah Upazila of Jamalpur district, Bangladesh. A total of 45 fishers were surveyed from November 2020 to April 2021. It was found that the family size of 53% of fishers was medium, consisting of 5-6 members. Most of the fisher communities belonged to the age group above 45 years old, represented by 100% Muslim. About 73% of fishers were less educated, 13% primary level, 7% secondary level, and 7% Secondary School Certificate passed and above, respectively. Most of the fishers (60%) have katcha houses with tin roofing, 7% have katcha house with straw roofs, 13% have semi- pucca houses and 20% have pucca houses. Around 93% of fishers used their own tube-well while only 7% used neighbours’ tube-well. All of the fisher household were connected with electricity supply. About 27% of fisher communities used katcha toilets, 46% used semi pucca toilets and 27% used pucca toilets. About 47% of fisher communities were dependent on village doctors, 33% got health service from Upazila health complex, 20% from MBBS doctors, and others. About 46% of fishers were engaged in fishing as their primary occupation while 27% in agriculture with fishing, 20% in daily labour with fishing and 7% in livestock rearing. About 33% of the fishers had low income, 40% had medium income and 27% had high income. The present study revealed that the fishers of Dengar Beel were mostly less educated, less privilege to attain modern technology-oriented training experience, less income and less awareness about sanitation and health facilities. So, provide soft loans to fishers, and strengthening people awareness has been might be helpful to improve the socio-economic status of fisher communities in Dengar Beel. Asian J. Med. Biol.

Literature about the fisher (Martes pennanti) contains the following contradictions: (1) the species is an old-growth specialist versus a forest generalist, and (2) it lives with marten (M. americana) with minimal interaction versus densities of the two species are inversely related. These contradictions beg the questions of what is fisher habitat and does habitat affect the interactions of the two Martes. These questions were examined by analyzing the distributions of fishers (n = 15,549) and martens (n = 40,516) harvested in Maine, 1980–1987. This period was chosen because it had relatively stable pelt prices that were believed to result in harvests reflecting population occurrences. The spatial distribution of mean harvests of fisher and marten were compared to each other, and to snowfall distribution and frequency throughout Maine, 1980–1987. Martens were common only in northwestern Maine and were associated with frequent (monthly [Formula: see text]) and deep (total monthly [Formula: see text]) snowfalls, December–March. Fishers were rare in northwestern Maine but were common throughout the rest of the state where snowfalls were less frequent. We hypothesize that regular accumulations of deep snow reduce the fisher's fitness (via decreasing recruitment, survival, or both), resulting in a low abundance in northwestern Maine. In addition, we hypothesize that martens are rare in southern Maine due to competition from a dense fisher population. These hypotheses were evaluated by looking at patterns in age and recruitment ratios of fishers (n = 2,706) and martens (n = 5,572) harvested in core and non-core habitats for each species, 1980–1984. We found low indices of fisher recruitment (P <0.001) in the marten's core habitat consistent with the hypothesis that deep and frequent snowfalls limit fishers. Few adult martens were harvested (P <0.001) in the core habitats of fisher, consistent with our hypothesis that high fisher densities limit marten populations. Assuming our hypothesis on fisher–snow relations is true, and given that canopy closure affects snow accumulation, fisher habitats deserve more consideration in forest management in regions with frequent powder-snowfalls, fragmented forests, or both. We acknowledge, however, that both of our hypotheses (i.e., snow limits fisher and fisher limit marten) need direct testing because association does not prove causation.

Aims: The COVID-19 pandemic caused devastating and far-reaching impacts on the economic construct of several countries. The fisheries sector in India was impacted by the nationwide lockdown causing severe disruptions in fishing and marketing activities. In this context, an analysis of the socio-economic impact of the pandemic on small-scale fisher (SSF) households in Kerala was done.
Study Design: The fishery income, employment, household consumption, and indebtedness of the small-scale fishers during the pre- and post-pandemic period were analyzed based on the data collected from small-scale fisher households in Alappuzha, Ernakulam and Malappuram Districts. The information on access to relief and support measures and alternate livelihood sources was also collected to assess the economic security of the fisher households.
Place and Duration of Study: The study was conducted during the pandemic years 2020 and 2021 in the selected coastal districts in Kerala state.
Methodology: Snowball sampling was adopted followed by telephonic interviews to collect the information from the fisher households. Descriptive statistics and one-way ANOVA were used for data analysis
Results: The annual fishing days declined from 134 to 82 days in Alappuzha district (38.8% reduction) and from 134 days to 70 days in Ernakulam district(47.76% reduction). The respondents in Ernakulam district reported a 34% reduction in consumption expenditure followed by 13% in Alappuzha and 11% in Ernakulam district. More than 75% of the respondents borrowed money to meet household expenses during the pandemic. The results indicated that the COVID-19 pandemic deepened the debt burden and exacerbated the livelihood constraints of the small-scale fishers
Conclusion: The Government transfer payments and relief measures during the pandemic were inadequate. The study proposes measures to improve the livelihood security and resilience of the fishers through the creation of alternate livelihood options, incentives to compensate for the loss of fishing days, debt relief measures, and sustainable markets.

This study examined the socio-economic characteristics of the artisanal fisher’s folks in the study area, the dominant fish in the landing site, the type of fishing gear used at the location, their contribution to fish landing, the effect of by-catch on artisanal fish production and food security in Igbokoda, Ilaje Local Government Area of Ondo State. Data was collect by the random distribution of a questionnaire using statistical analysis such as; pie chart, bar graph and regression analysis to collate and show the data obtained from the study area. The output of an artisanal fisher was affected by gender and the season of fishing and not the educational status of the fisher men, 64% of the fishers were male and the highest age bracket was between 31-40 years. Only 10% of the respondents have tertiary education and 64% of the fishers have between primary and secondary education. The level of profitability was average (64%), 98% of by-catch were demanded for. This study hereby proves that fishing is profitable and therefore, suggests that policy variables such as extension, education, and credit identified in the study as important determinants of efficiency of artisanal fishers should be strengthen for sustainable fish production in the State and Nigeria at large

Abstract Small-scale fishers are frequently exposed to a variety of hazards that threaten their livelihood. Different socio-cultural, natural resource, environment conditions potentially create unique vulnerability and livelihood strategies which may exist in different places. Therefore, an investigation in two different fishing communities was carried out to understand the similarities and different of livelihood strategy works in both places. The study was conducted in two small scale fisheries community in village Betahlawang (north of java) and Glagah (south of Java). This research aims to describe livelihood aspects and strategies of fisher communities in both locations under different fishery resource and their dependency on the fishery through systematic surveys. The study showed that both communities are highly dependent on natural capital which mainly the abundance of the fishery resources. Others factors affecting both communities’ sustainable livelihood are the uncertainty in catch, weather and policy, limited capital ownership, access, and knowledge and skills other than fishing. Although the two study sites share some capital similarities, the livelihood vulnerability and their strategy is different. Betahlawang fishers more vulnerable than Glagah fishers because Glagah fishers has more diverse livelihood alternatives.

Full textAbstract:
We used the theory of the ideal free distribution (IFD) as a framework to understand the mechanisms underlying fishing site selection by Anguillian artisanal fishers exploiting shallow-water coral reefs. Contrary to the predictions of IFD, fishers did not distribute themselves so that average reward was equal among fishers using different fishing methods or among fishers using the same method. In addition, fishing pressure did not increase with resource availability. Key assumptions of the IFD were not met. The distribution of Anguillian fishers was not "ideal" because lack of knowledge prevented fishers from choosing fishing grounds with the greatest rewards. Not all fishers sought to maximise profit. In addition, all fishers were not "free" to distribute themselves among reefs owing to variation in social, economic, and physical characteristics of fishers that constrained fisher movements and ability to extract resources. This study shows that as a null model the IFD is useful to frame studies designed to gain detailed insights into the complexity and dynamics of a small-scale fishery. Alongside ecological data, this framework may inform efficient and effective development of reef and fishery management practice.

Late-winter habitat use by the Fisher, Pekania pennanti (Erxleben, 1777) in northwestern Saskatchewan was assessed in February 2009, 2011, and 2012. A total of 78 Fisher tracks were recorded over 60 300 m of snowshoe surveys. Fisher tracks were significantly less frequent than expected in Tamarack (Larix laricina [Du Roi] K. Koch) stands with > 40% crown closure and mainly 0–10 m trees (P < 0.05) and in open areas. Fishers used other habitat types equal to availability, including muskeg and coniferous, mixed, and deciduous forest stands. Maintaining mosaics of forest stands of different seral stages interspersed with muskeg would meet the late-winter habitat needs of Fishers in the Boreal Plains Ecozone of northwestern Saskatchewan.

Full textAbstract:
Fishers seek to maximize profits, so when choosing where to fish, they must consider interactions among the environment, costs, and fish prices. We examined catcher vessels in the US Bering Sea fishery for walleye pollock (Gadus chalcogrammus) (2003–2015) to characterize fisher responses to environmental change (e.g., abundance and water temperature). When pollock were abundant and the water warm, the fleet fished in similar locations. When temperatures were cooler or pollock abundance declined, two fishing strategies emerged, depending on the processor where a vessel delivered. One vessel group, whose catches were more likely to become fillets, often made shorter trips, requiring less fuel and time at sea. A second vessel group, whose catches were more likely to become surimi, traveled farther from port to regions with higher catch rates but generally smaller fish. By fishing in different locations to satisfy different markets, the fleet sustained revenues and buffered against environmental change. We identify a suite of socioeconomic indicators of the impacts of ecosystem change and illustrate that a one-vessel-fits-all approach may be insufficient for assessing the resilience of fleets.

Full textAbstract:
During stock assessment, fishery-dependent observations are often used to develop indices of abundance or biomass from catch per unit of effort (CPUE) and contribute catch at size or age information. However, fisher behavior, rather than scientific sampling protocols, determines the spatial and temporal locations of fishery-dependent observations. As a result, trends from fishery-dependent data may be a function of fishing activity rather than fish population changes. This study evaluates whether data collected from commercial fishing fleets in the Gulf of Mexico are representative of trends in fish population size. A coupled bioeconomic agent-based model was developed to generate simulated fishery data, which were used to populate an age-structured stock assessment. Comparison of stock assessment results with simulated fish population dynamics showed that management advice from assessment models based on fishery-dependent data could be biased. Assessment of fish with small home ranges harvested by fishing fleets that frequent the same fishing grounds could cause overestimation of fishing mortality. Not accounting for the spatial structure of the fishers or fish can cause biased estimates of population status.

Full textAbstract:
The Galápagos Islands, a world heritage region for the protection of the unique terrestrial and marine wildlife, are also home to a small human population, dependent on fisheries. There was a lucrative sea-cucumber (Stichopus fuscus) fishery in the islands, which began in 1992. After a rapid expansion in the Galápagos archipelago, the fishery has declined and now persists predominantly around the western islands. Initially, the fishery was largely illegal and uncontrollable. Subsequently, a co-management framework developed, with fisher participation. Gradually enforcement improved, apparent corruption declined, and research capacity increased. Although stock abundance surveys have been carried out annually since 1993, the paucity of background biological and fishery information does not allow rigorous stock assessment. The achievements of co-management through the participation of fishers in research and management have been: an acceptance of management controls on numbers of fishers and quotas, a reduction in conflict and increased co-operation. Persistent problems have been: weak enforcement capacity, limited funds for patrolling and research, corruption and declining stock abundance. Proposed application of precautionary principles to management, including a range of fishery indicators, may save the fishery from collapse. The principles are applicable to many other data-poor fisheries globally.

Full textAbstract:
Catch share systems are generally expected to increase economic rents in fisheries by increasing harvest efficiency, reducing capital costs through consolidation, and increasing the value of landed catch. However, these benefits may have costs, as consolidation and the potential for associated change in spatial distribution in landings can hinder social objectives such as maintaining access for fishery-dependent communities and small owner-operators. Achievement of such fishery management objectives are determined by changes in fisher behavior, which may be complex and difficult to predict. Predicting fisher behavior is particularly challenging in multispecies fisheries, in which the mix of species is a determinant of where and when fishing effort and landings occur. We evaluate changes in overall fishing effort, species targeting, and determinants of fishing location choice in response to catch shares in the US West Coast Groundfish Trawl Fishery. We found reductions in total fishing effort, increased targeting of some species, and no evidence of spatial effort concentration. Key determinants of location choice (distance, expected revenue, and recently fished locations) were similar among time periods, but after catch shares there was more avoidance of areas that lacked recent fishing activity or associated information with which to develop expectations of catch and bycatch. Additionally, location choice remained constant with up to 100-fold financial penalties on bycatch species.

Abstract Fishers' knowledge research (FKR) aims to enhance the use of experiential knowledge of fish harvesters in fisheries research, assessment, and management. Fishery participants are able to provide unique knowledge, and that knowledge forms an important part of “best available information” for fisheries science and management. Fishers' knowledge includes, but is much greater than, basic biological fishery information. It includes ecological, economic, social, and institutional knowledge, as well as experience and critical analysis of experiential knowledge. We suggest that FKR, which may in the past have been defined quite narrowly, be defined more broadly to include both fishery observations and fishers “experiential knowledge” provided across a spectrum of arrangements of fisher participation. FKR is part of the new and different information required in evolving “ecosystem-based” and “integrated” management approaches. FKR is a necessary element in the integration of ecological, economic, social, and institutional considerations of future management. Fishers' knowledge may be added to traditional assessment with appropriate analysis and explicit recognition of the intended use of the information, but fishers' knowledge is best implemented in a participatory process designed to receive and use it. Co-generation of knowledge in appropriately designed processes facilitates development and use of fishers' knowledge and facilitates the participation of fishers in assessment and management, and is suggested as best practice in improved fisheries governance.

In this study we tested the basic premise that fishers’ knowledge provides similar perceptions about exploited stocks to data gathered by standardised monitoring in a small-scale commercial fishery. To that end, we compared temporal trends in catch and individual size for fish species between data obtained from interviews with fishers and a 25-year dataset from a landing monitoring program in the Itaipu Reservoir (Brazil). Fishers described with accuracy changes in species composition of the catches, from large migratory species of high commercial value (common before impoundment) to migratory species of low commercial value and sedentary species following damming. Temporal trends in catches reported by fishers and documented in the landing data matched for most species. Histories diverge when absolute values are involved, such as when fishers were asked to recall their largest catch. Fishers were homogeneous in their reports, indicating that instead of individual opinions, they revealed knowledge resulting from their observation and fishery experience. Fishers can be a reliable source of information for detecting changes in catches over time, especially when large-scale habitat changes have occurred within the time scale of a fisher career. Fishers may be key partners to be considered by managers in information gathering for effective management.

Abstract Fisheries management is usually supported by technical and financial measurements (i.e. logbooks and market data), which are helpful for ecological or economic assessments. Yet this information is not able to address social heterogeneity and fisher motivations, which are key to understanding fisher behaviour. This case study of the demersal segment in the Netherlands shows that combining quantitative analysis of logbooks with qualitative data collected by engaging with fishers can capture both fishing activity and its motivations, generating a more social understanding of fisher behaviour. A métier analysis of logbook data describes five dominant fishing practices among the selected segment. Twenty-five in-depth interviews with fishers along with focus groups including other experts identify three social factors that influence fisher behaviour in the Dutch demersal fleet: business structure, working rhythm, and polyvalence. The results show that motivations for fisher behaviour are more complex than complying with regulations or seeking profit: social factors also influence fishing activity. Furthermore, these social factors have real implications for the impacts of management measures on both the fishing communities and the environment, especially in times of change. These results are useful for management strategy development or evaluation because they are feasibly observable through existing data collection protocols.

Small-scale marine capture fisheries have contributes to community welfare at Yogyakarta’s south coast. Government has planned some programs to develop fisheries. The development supposed only at rational effort in which fishers still gain advantages. Precautionary approach using bio-economic model of Gordon-Schaefer was applied to analyze the issue. The linear regression model of catch per unit of effort (C/f) (CPUE) and effort (f) was C/f = 59,851 – 0,0005f (R2 = 82, 71%). Fish price assumed at Rp 7,735.19 /kg with operational cost of Rp 59,835.67/trip. Total revenue and effort at maximum sustainable yield was predicted at Rp 13,396 billion and 56,860 trip (equals to 327 vessels), respectively. Fisher income at this level was Rp 167,774.51/trip/vessel. Fish exploration level in this area has already closed to total allowable catch. Free access equilibrium in which cost is equal to revenue might reach at effort of 102,231 trip (equals to 568 vessels). Managing fisheries at maximum economic yield might rise fisher income 17.83% comparing to maximum sustainable yield, but total revenue decreased 1.77% at 56.13% of existing effort. Some management strategies should be promoted and regulated for the fishery exploitation. Based on the results, those possible strategy were 1) limiting investment through regulation and permission; 2) improvement of fishers productivity through technology improvement to exploit under-used fish resources; 3) expanding the fisheries activity to offshore through harbor development and social preparation; 4) marketing improvement through revitalization of fish action; 5) improving hadling and post harvest fish technology through training and extension; 6) the increasing of bargaining position through empowering fishers group; 7) promoting alternate incomes through integrated coastal tourism development; and 8) avoiding competition and conflict through developing Java’s south coast cooperation. Participatory approach in planning, developing and evaluating should be promoted to develop fishery a southern coast of Yogyakarta.

Abstract Assignment problems in quota-managed fisheries are caused by spatial and temporal heterogeneity in the productivity of the stock. If the quota management system is not fully delineated (e.g. harvest rights assigned to particular areas) then fishers will compete with each other and overexploit parts of the fishery where or when the quota unit value is highest (i.e. fishing costs low and/or market price high), leading to economic rent dissipation. This study used experimental economics to assess the effectiveness of fishery temporal closures and income-sharing fishery cooperatives in resolving assignment problems across three different fisheries with varying levels of fisher heterogeneity (i.e. numbers of quota owners and lease quota fishers). While most fisheries were successful in reducing economic rent dissipation under the fishery closure management structure relative to their baseline(s), fisheries characterized by a greater number of lease quota fishers were less effective. This was due to the differential values that lease quota fishers place on the resource relative to quota owners, due to having insecurity of tenure and diminished wealth in having to bid for a quota package and pay for it using their revenue from fishing. Conversely, income-sharing fishery cooperatives were equally successful across all three fisheries in reducing assignment problems relative to their baseline(s). This was because income-sharing created an incentive to coordinate fishing effort, particularly among heterogeneous groups. While requiring further exposition in the field, these experimental results represent a first step in identifying management institutions that may assist fishers under quota management to resolve assignment problems in a dynamic environment.

SUMMARYTwo main drivers of global trends in noncompliance of marine protected areas regulations are food and income security. Declines in fish stocks have resulted in greater concerns for food security, especially in developing and coastal areas, and calls for environmental conservation are growing. Planning of marine protected areas has traditionally been based on biological and ecological data, only recently focusing on the human communities that are significantly dependent on coastal resources. The hypothesis that marine resource use is determined by socioeconomic factors (such as food security and income) and livelihood options was tested in two communities on the island of Rodrigues (Western Indian Ocean). As livelihood development can be a response to fisher displacement by protected areas, willingness towards alternative livelihood options and the differences in this between fisher demographic groups were also examined. Using semi-structured interviews, 72 fishers were surveyed on topics such as fishery and marine protected area (MPA) regulation noncompliance, current livelihoods and willingness to consider alternative livelihoods. Fishers believed Rodrigues fisheries suffer from high levels of noncompliance, owing mainly to a lack of livelihood alternatives and depleted stocks. Rodriguan fishers had low mobility, both within the fishery (for example gear types used and target species) and in movement to occupations outside the fishery. The fishers were generally willing to consider alternate livelihoods. Age was significantly correlated with overall willingness to consider alternative work, while gender and village were found to have a significant relationship with types of work that an individual was willing to consider. Policy makers and marine resource managers need to identify drivers of noncompliant behaviour and examine livelihood preferences at different scales (individual, within and between communities) prior to users being affected by MPA created displacement to more effectively address marine conservation and food security goals. The findings offer new empirical evidence to strengthen support for arguments that could be made by policy makers to demand more balanced consideration of the effects of MPAs on socioeconomic factors along with environmental considerations in communities highly dependent on access to the marine areas that will be affected by MPAs.

The present study assessed the levels of literacy, health, income and livelihood security of fisher households across different fisheries sectors in Kerala. Primary data collected across 567 households during January to December, 2011were used for the study. The general trend in Kerala shows that majority of the fisherfolk were of the age group 36-55, with a small family norm and high literacy rate. The marine capture sector has the highest annual income in comparison with other sectors but registered higher indebtedness. While the highest income from non-fishery activity was from labour followed by business, other sectors and agriculture. The study revealed that the fishers spend their major share of income towards food expenditure. Inspite of the income from various sources, majority of the households are swamped with debts which make them to rely on private money lenders for sustaining their living standards. The study is a cross sectoral analysis of the fisher households in Kerala and provides a base for implementing developmental plans for the betterment of the fishing community.

These Fisher Women working in the “Warrahs” have been deprived off the basic fundamental rights of an Industrial Worker. This discrimination is because the fisher workers being women, resulting in appalling work conditions, low wages, insecurity of job and all types of malpractices are inflicted upon them. All these malpractices are drastically causing health problems and low productivity of fisher women thereby increasing poverty in the society.

Fishery management relies on forecasts of fish abundance over time and space, on scales of months and kilometres. While much research has focussed on the drivers of fish populations, there has been less investigation of the decisions made day-to-day by fishers and their subsequent impact on fishing pressure. Studies that focus on the fisher decisions of smaller vessels may be particularly important due to the prevalence of smaller vessels in many fisheries and their potential vulnerability to bad weather and economic change. Here we outline a methodology with which to identify the factors affecting fisher decisions and success as well as quantifying their effects. We analyse first the decision of when to leave port, and then the success of the fishing trip. Fisher behaviour is here analysed in terms of the decisions taken by fishers in response to bio-physical and socio-economic changes and to illustrate our method, we describe its application to the under 10-meter fleet targeting sea bass in the UK. We document the effects of wave height and show with increasing wave height fewer vessels left port to go fishing. The decision to leave port was only substantially affected by time of high tide at one of the four ports investigated. We measured the success of fishing trips by the landings of sea bass (kg) per metre of vessel length. Fishing success was lower when wave height was greater and when fish price had increased relative to the previous trip. Fuel price was unimportant, but a large proportion of the variation in success was explained by variation between individual vessels, presumably due to variation in skipper ability or technical restrictions due to vessel characteristics. The results are discussed in the context of management of sea bass and other small-scale inshore fisheries.

Effective fisheries management requires an understanding of human dimensions. This study elicited the salient motivations for recreational blue swimmer crab and black bream fishing in Western Australia and whether these views differed depending on the fishing location and/or the characteristics of the fisher. Crab fishers were strongly consumption-orientated and aimed to “catch big crabs” and “catch enough crabs to eat”. Furthermore, 91% consumed their catch, with only 2% practicing catch-and-release fishing. In contrast, 81% of black bream fishers did so for the sport/challenge, with the strongest motivation being to catch a bream considerably above legal size and with food only selected by 15% of respondents; most fishers released caught fish. The marked differences between the fisheries for the two species, which co-occur in the same estuaries, are likely driven by the accessible nature of the crab fishery, ease of catching crabs, the low cost of fishing equipment, and their taste. Fishing for black bream, however, requires more expensive equipment, patience, and a greater skill level. Fishers considered crabbing to be as important as other fishing and outdoor activities, whereas bream fishers considered bream fishing considerably more important, reflecting the trophy nature of this fishery.

Abstract Collecting spatial information on fisheries catch and effort is essential to understanding the spatial processes of exploited population dynamics and to manage heterogeneously distributed resources and uses. The use of fishers' knowledge through geographical information systems (GISs) is increasingly considered as a promising source of local information on small-scale coastal fisheries. In this paper we describe the first framework for mapping entire small-scale coastal fisheries using fishers' knowledge on catch size and fishing effort. Four mangrove and coral reef fisheries targeting invertebrates or finfish in New Caledonia (southwest Pacific) were mapped following a five-step framework: (i) stratified random sampling of regular fishers; (ii) collection of fishers' knowledge of fishing areas, fishing effort, and catch size through map-based interviews; (iii) data integration into a spatial geodatabase; (iv) statistical extrapolation of fisher data to the fishery scale; and (v) mapping of catch, effort, and catch per unit effort (CPUE) for each fishery using a GIS overlay procedure. We found evidence that fishers' knowledge supplied precise and accurate quantitative and spatial information on catch size, fishing effort and CPUE for entire fisheries. Fisheries maps captured the fine-scale spatial distribution of fishing activities in a variety of ways according to target taxa, gear type, and home ports. Applications include area-based marine conservation planning and fishery monitoring, management, and governance. This integrated framework can be generalized to a large range of data-poor coastal and inland small-scale fisheries.

Abstract Marine protected areas (MPAs) are increasingly used to address multiple marine management needs, and the incorporation of stakeholders into the MPA planning and designation processes is considered vital for success. Commercial fishers are often the stakeholder group most directly affected by spatial restrictions associated with MPAs, and the success of MPAs often depends, at least in part, on the behaviours and attitudes of fishers. MPA planning processes that incorporate fishers, and minimize the negative impact of MPA designation on the fishing community, should therefore have a greater chance of success. Here, the incorporation of both quantitative and qualitative fisher-derived data in MPA planning is investigated using strategic conservation planning software and multi-scenario analysis. We demonstrate the use of spatial access priority data as a cost layer, and suggest a process for incorporating fishers' MPA suggestions into planning scenarios in a transparent, but flexible, way. Results show that incorporating fisher-derived data, both quantitative and qualitative, can significantly reduce the cost of MPA planning solutions: enabling the development of MPA network designs that meet conservation targets with less detrimental impact to fishing community. Incorporating fishers and fisher-derived data in MPA planning processes can improve both the efficiency and defensibility of planning outcomes, as well as contribute to reducing potential conflicts between biodiversity conservation and the fishing industry.

The major aim of this research was to determine the application of net production as management strategy for fisher women activity in Selangan Laut of Bontang City in the field of integrated domestic and public sectors in order to increase the quality life of fishers family. The results showed that fisher women activities were classified as follows: (a) in domestic sector such as performing meals for the family; (b) in social aspect like providing meals for public/specific events, and (c) in productive one, i.e. the making of fish paste, sea weeds processed product, and salted and dried fishes, the performance of grilled fish culinary services and sea weeds cultivation activity. The activities above have a prospect to implement the net production. The application of net production can be done by managing and utilizing solid and liquid wastes. In addition, the further efforts to ensure net production are formulating procedure operation standard of net production, organizing raw materials and their supplement by the creation of ‘come in first come out first’ model, preparing adequate equipments, increasing the number of demand, and extending market channel through the creation of product diversification, modification and packaging

This study explores the marginalization of a poor fishing community in Gwadar, Pakistan. The study provides an insight into how different levels of power, such as hidden, visible/pluralist, and invisible ideological powers, are used in policy arenas to hinder fishers’ access to participatory spaces, decision-making, and resource use. By employing Gaventa’s power cubes analytical model, we analyze fishers’ experiences and prevailing scenarios. Qualitative research methods were used to collect data, including in-depth interviews and participant observation. The finding shows that the interests of the fishing community in fishery policies and ongoing development projects are excluded both with intention and unintentionally. The exclusion of the local fisher community from key spaces brings interruptions and transformations that influence their lives. Due to this, they are induced to join insurgent groups to confront exclusion-based policies in Gwadar, Pakistan.

Abstract Community management of inland openwater fisheries in Bangladesh has introduced and practiced through the Community Based Fisheries Management (cbfm) approach with partnership arrangement of government and non-government organisations, fisher communities and other stakeholders. One of the principles behind community based fisheries management is to improve fishers’ income and reduce transaction costs efficiently. The implementation of the cbfm approach has experienced a significant contribution towards fishers’ income and transaction costs. cbfm arrangement introduced fisher led, community led and women led approach. Community based organisations (cbo s) as local institutions have been established through community participation under cbfm approach. This paper presents and assesses the impact of cbfm approaches on fishers’ income and transaction costs in inland openwater fisheries in Bangladesh. This study might have policy implication to scale up cbfm approach to promote fishers’ income for better management of inland open water fisheries with a long term commitment.

This paper investigates the impact of exchange rate movement and the nominal interest rate on inflation in Ghana. It also looks at the presence of the Fisher Effect and the International Fisher Effect scenarios. It makes use of an autoregressive distributed lag model and an unrestricted error correction model. Ordinary Least Squares regression methods were also employed to determine the presence of the Fischer Effect and the International Fisher Effect. The results from the study show that in the short run a percentage point increase in the level of depreciation of the Ghana cedi leads to an increase in the rate of inflation by 0.20%. A percentage point increase in the level of nominal interest rates however results in a decrease in inflation by 0.98%. Inflation increases by 1.33% for every percentage point increase in the nominal interest rate in the long run. An increase in inflation on the other hand increases the nominal interest rate by 0.51% which demonstrates the partial Fisher effect. A 1% increase in the interest rate differential leads to a depreciation of the Ghana cedi by approximately 1% which indicates the full International Fisher effect.

The habits of Indonesian fisher who ride into the territory of the Australian fisheries often causing fluctuative relations between two countries, because repressive action of the Australian Government's apparatus. Therefore, the purpose of this study are: to assess the economic interest of fisher when get into the fishery regions of Australia, to analyze the offense of illegal fishing, and to get the eradication strategies of illegal fishing in two countries agreement areas. This study is a descriptive analysis, using a normative juridical approach which is equipped with comparative approaches. Based on the analysis yielded that 1) sea cucumbers and sharks are the main target of Indonesian fisher, wherein the value of profits from sea cucumbers of AU $ 14,000-AU $ 30,000, 2) illegal fishing violation occurred, i.e.; breach of the agreement not only operating areas, the utilization of fishery resources, environmental pollution, but also agents of illegal immigrants, 3) eradication of illegal fishing through the establishment of a legal approach by arbitration forming, and economic approach with alternative livelihoods development.

This research explores the issue of the legal entity for fisher-women. Feminists Legal Theory is the main foundation. This theory seeks to criticise and dismantle the law by questioning the existence of laws that bring injustice to women's groups. In the Indonesian context, where the influence of patriarchal ideology and legal positivism theory is still active, the view that the law is believed to be neutral and objective has resulted in many things that discriminate and marginalise women's groups. This research presents the criticism of Law Number 7 of 2016 concerning the Protection and Empowerment of Fishermen, Fish Cultivators and Salt Cultivators for the recognition of the legal entity of fisher-women. This research is theoretical with the type of literature study focusing on ideas using a feminist perspective research approach. The results of the study indicates the that Law Number 7 of 2016 concerning the Protection and Empowerment of Fishermen, Fish Cultivators and Salt Farmers contains many weaknesses. There is a prejudice towards the work of fishers, there is a problem defining fishers because women are excluded from defining fishers, the absence of recognition of fisher-women affects the law and becomes indirect discrimination because of gender blindness and does not take into account in terms of women's experience or interests.

This paper outlines the alternative livelihood practices used by artisanal fishers for household improvement in five Zanzibar Islands fishing villages: Kizimkazi Dimbani, Chwaka, Unguja Ukuu Kaepwani, Tumbe Mashariki, and Michenzani. The cross-sectional research design was used to collect quantitative data via a questionnaire survey and qualitative data via Focus Group Discussions (FGDs) and key informant interviews. Data were collected from a sample of 333 artisanal fishers drawn from the 1991 population using the Yamane formula. According to the findings of the study, approximately half of the artisanal fishers (53.45%) did not engage in any alternative livelihood practice to support the livelihood of their households and instead relied solely on artisanal fisheries. (23.12%) of the artisanal fishers were farmers, (9.91%) were seaweed farmers, and (5.41% were animal keepers. A small percentage of artisanal fishers (8.11%) engage in petty trade, tourism, and dagaa processing for sale. It is therefore recommended that the respective government, in collaboration with other fisheries stakeholders, establish the sustainability of alternative livelihood opportunities for artisanal fisher communities in order to improve their household livelihoods by diversifying their household survival and reducing the challenge of overexploitation of fishery resources.

Full textAbstract:
Fisheries management has evolved in Malawi from a traditional system to a centralized regime and lately to co-management fisheries systems, although, success stories about sustainability of the fishery resources are few. Open access nature of fisheries resources has posed a challenge to management regimes. Resource over exploitation has continued in a majority of fisheries worsened by large stretches of the shoreline manned by a single fisheries field staff, and limited capacity by DoF to monitor and manage the fishery. However, isolated localities have upheld management styles that have facilitated sustainable exploitation. Mbenji Island fishery ‘managers’ have ensured high compliance to fisheries rules and regulations among fishers through strict enforcement and maintained abundant fish stocks amid visibly declining levels of fish in vast localities of Lake Malawi and other water bodies in Malawi. There is,therefore, need to take the Mbenji Island success story to other fishing communities to learn from their fisheries management strategies. Information Communication Technology (ICT) as a powerful means in mobilizing communities to take charge of their own development should support ‘best practices’ and offer fishing communities access to the same type of services and advantages. If appropriately applied,ICT can provide for real-time monitoring of fisheries resources as fishers alarm law enforcers to move in at appropriate times. Fishers also strike deals on mobile phones for the day's catch even before landing at shore. This reduces post-harvest waste from delayed handling of fish. Computers have been used for data management, storage and analysis as well as accessing internet services. Studies have shown commonalities in fisher communities in terms of socio-economic and cultural characteristics. On the basis of such an advantage, more could be shared among such communities. Management success can be adopted by other communities of fishers through use of ICT such as radio programs (supplemented by phone-in sessions) undertaken by local-level resource users. These programs provide locally available information and knowledge on best practices aimed at sustainability with means within communities. This encourages community members in other localities to come together to seek the way forward on the basis of lessons from successful communities aired on local radio stations (both community or national radio stations). It is easier to adopt practices that have worked in near vicinities. After all,what is currently called co-management is seemingly based on indigenous knowledge of fishers and other resource users. Mbenji Island is one of the custodians of ICT option in small-scale fisheries management of Lake Malawi. Information Communication Technology provides opportunity for both the Malawi Department of Fisheries (DoF) and fishers with information about fisher community activities including catch and market regardless of distance.

Full textAbstract:
Social networks can profoundly affect human behavior, which is the primary force driving environmental change. However, empirical evidence linking microlevel social interactions to large-scale environmental outcomes has remained scarce. Here, we leverage comprehensive data on information-sharing networks among large-scale commercial tuna fishers to examine how social networks relate to shark bycatch, a global environmental issue. We demonstrate that the tendency for fishers to primarily share information within their ethnic group creates segregated networks that are strongly correlated with shark bycatch. However, some fishers share information across ethnic lines, and examinations of their bycatch rates show that network contacts are more strongly related to fishing behaviors than ethnicity. Our findings indicate that social networks are tied to actions that can directly impact marine ecosystems, and that biases toward within-group ties may impede the diffusion of sustainable behaviors. Importantly, our analysis suggests that enhanced communication channels across segregated fisher groups could have prevented the incidental catch of over 46,000 sharks between 2008 and 2012 in a single commercial fishery.

Full textAbstract:
Abstract Understanding current and predicting future behaviour of fishers is fundamental to designing effective management strategies. The management of most recreational fisheries requires releasing fish not meeting size or daily limits, and assuming the majority survive. In the Marlborough Sounds, New Zealand, a maximum size limit imposed on the blue cod (Parapercis colias) fishery aimed to achieve a more balanced sex ratio for this hermaphroditic species. We tested three alternative size limit scenarios (current, increased, and no maximum size) in a study with recreational fishers (N = 420) to investigate whether regulation change would influence their intentions to discard fish and fishing satisfaction. Increasing or eliminating the maximum size led to lower discard intentions and greater fishing satisfaction, suggesting strategies to achieve both management goals (e.g. more large fish) and increased fisher satisfaction (potentially increasing compliance). More broadly, the results demonstrate the benefits of using scenarios to evaluate potential regulatory changes prior to implementation.

Full textAbstract:
Abstract Species-transformation provisions allow fishers to convert quota of one species to that of another species at prescribed conversion rates. These provisions, along with other catch-quota balancing mechanisms, are meant to aid fishers in matching available quota to actual catch so that incentives to discard are reduced. In this paper, we use a bioeconomic model to examine how species-transformation provisions affect sustainability and profitability of a multispecies fishery. We base parameterization of the model loosely on management of the Icelandic demersal fishery, which currently employs one of the broadest implementations of species transformations. To represent fisher behaviour in each year, effort is allocated among two or three métiers, such that total profit for that year is maximized. Each métier represents a combination of three species’ catchability rates that define which species are targeted by each métier and how independent a species’ catch rate is from that of other species. Assumptions regarding the degree to which fishers can target specific species by shifting effort between métiers, as well as how relative profitability among métiers varies, are paramount to understanding more generally how fishing regulations such as species transformations can be expected to change fishing patterns. This constraint depends not only on how strongly associated species catches are within a métier but also on relative species abundance and what alternate métiers are available.

<p><strong>Abstract </strong></p><p>Rainfall drives fishery fertility in Mweru-Luapula, thus rainfall variability contributes to frequent changes in fishing catches. Fishers and traders have adapted their institutions to this variable ecology in a variety of ways, including learning to read the fishery for productive periods and practicing multiple modes of income procurement. By accurately identifying inter-annual, inter-decadal, and longer spans of rainfall trends, future high and low yields can be forecast. This article presents and analyzes annual rainfall in the fishery from 1916-1992 and quantitative fish market data comprised of observed fish catch numbers by species in three markets from September 2004 to September 2005. It uses political ecology to better understand fish production, trade, and subsistence in this South-Central African freshwater fishery. We combine qualitative analysis of fisher and marketer perceptions of the fishery and knowledge of rainfall patterns to show how human behavior is not "tragically" driven, but instead based on the state of the ecological, sociocultural, and socioeconomic environment at a given time.</p><p><strong>Keywords</strong>: African freshwater fisheries, rainfall modeling, political ecology, Mweru-Luapula, Zambia, climate change</p>

Full textAbstract:
The failures of traditional target-species management have led many to propose an ecosystem approach to fisheries to promote sustainability. The ecosystem approach is necessary, especially to account for fisheryecosystem interactions, but by itself is not sufficient to address two important factors contributing to unsustainable fisheries: inappropriate incentives bearing on fishers and the ineffective governance that frequently exists in commercial, developed fisheries managed primarily by total-harvest limits and input controls. We contend that much greater emphasis must be placed on fisher motivation when managing fisheries. Using evidence from more than a dozen natural experiments in commercial fisheries, we argue that incentive-based approaches that better specify community and individual harvest or territorial rights and price ecosystem services and that are coupled with public research, monitoring, and effective oversight promote sustainable fisheries.
