“…This observation contrasts with that made in Fiji, where older fishers tended to have a more pessimistic point of view about shellfish stock depletion (Bao and Drew, 2017). Our study shows the potential utility of local ecological knowledge (LEK) of fishers in understanding stock status in artisanal fisheries in which longitudinal data on catches are often lacking (Medeiros et al, 2018). The dramatic increase in participation rates that we report for Samoa's trochus fishery should be a concern and stricter management measures might be needed to ensure sustainability.…”

Understanding Gender and Factors Affecting Fishing in an Artisanal Shellfish Fishery

Fishing strategies, effort and harvests of small-scale fishers are important to understand for effective planning of regulatory measures and development programs. Gender differences in fishing can highlight inequities deserving transformative solutions, but might mask other important factors. We examined fishing modes, fishing frequency, catch-per-unit-effort (CPUE), resource preferences and perceptions of fishery stock among artisanal gastropod (trochus) fishers in Samoa using structured questionnaires and mixed effects models. The fishery has an extremely modest carbon footprint of 18-23 tons of CO 2 p.a., as few fishers used motorized boats. Trochus (Rochia nilotica), an introduced gastropod, was the second-most harvested resource, after fish, despite populations only being established in the past decade. Daily catch volume varied according to gender and villages (n = 34), and was also affected by fishing effort, experience, assets (boat), and fishing costs of fishers. Boat users had much higher CPUE than fishers without a boat. Fishers who practised both gleaning and diving caught a greater diversity of marine resources; effects that explained otherwise seeming gender disparities. Trochus tended to be ranked more important (by catch volume) by women than men, and rank importance varied greatly among villages. Local ecological knowledge of fishers informed the historical colonization of trochus around Samoa and current trends in population abundance. Fishing efficiency, catch diversity and perspectives about stocks were similar between fishermen and fisherwomen, when accounting for other explanatory variables. Greater importance of these shellfish to women, and gender similarities in many of the fishing responses, underscore the need to ensure equal representation of women in the decision making in small-scale fisheries.

“…Studies with this social group have demonstrated that small-scale fishers apply LEK in their daily resource exploration practices and have relevant knowledge about the biology and ecology of fishery resources in their region (Silvano & Begossi 2012, Lima et al 2018, Medeiros et al 2018. The combination of this source of information with academic knowledge can result in more assertive management practices, as well as may create new hypotheses of studies, changing the scientific knowledge (Zappes et al 2013).…”

In order to contribute to the management of small-scale trawling fishing of the Xiphopenaeus kroyeri shrimp, the aim of this study was to evaluate the local ecological knowledge (LEK) and the conservationist attitudes of artisanal fishers in four fishing communities along the central Brazilian coast. This study was based on 80 ethnographic interviews conducted in two communities are in the state of Bahia (Santa Cruz Cabrália and Barra de Caravelas) and two communities in the state of Espírito Santo (Barra Nova and Anchieta). The fishers present knowledge compliance with literature, except in aspects reproductive of the shrimp and are willing to exchange knowledge with researchers. The mean attitude index of the fishers was 0.65. Education activities should focus on the reproductive biology of shrimp to include fishing communities in the drafting of legislation about closed season period, as this issue is directly related to possible divergences between fishers do not adhere to them. The results suggest that, dialogue and knowledge exchange is necessary among the stakeholders, including the fishers, scientists and managers, who are responsible for the elaboration of management measures.

“…These factors include water color, wind direction and current, lunar periodicity, sediments and topography, celestial navigation, birds and animals, mangroves and fishing sites. Grant and Berkes (2007) identified nine categories of knowledge, that are important for finding and catching large pelagic fish, including seasons, bait use, gear technology, weather conditions, fishing practices, fish habits and behavior, fish movements, "popular oceanography" (seabirds, seawater color, current), and fish stomach contents (Medeiros et al, 2018).…”
