What can be learned from fishers? An integrated survey of fishers’ local ecological knowledge and bluefish (Pomatomus saltatrix) biology on the Brazilian coast
TLDR
The results and approach could help involve fishers in management, thus contributing to development of co-management systems more suitable to local conditions and to complex tropical fisheries.Abstract:
Bluefish (Pomatomus saltatrix) has a worldwide distribution, being targeted by fishers all along its range, which includes the Brazilian coast. We formulated and checked hypotheses regarding bluefish diet, migration, and reproduction based on fishers’ local ecological knowledge (LEK). We interviewed 49 experienced fishers (40 years and older) from five communities along the Brazilian coast and analyzed the diet and reproduction of 185 fish. According to fishers’ LEK, the bluefish spawn mainly during the winter, migrate throughout year (from the South to North), and eat mainly small fish (Clupeidae and Engraulidae), plus shrimp and squid. The biological survey confirmed the hypothesis on bluefish diet (78% of fish with stomach contents had fish in their stomachs) but not that on reproduction: we observed larger fish and more fish with visible eggs during summer and autumn. Migratory movements mentioned by fishers agreed with literature data. Besides providing data to support conventional management decisions in the absence of biological surveys, our results and approach could help involve fishers in management, thus contributing to development of co-management systems more suitable to local conditions and to complex tropical fisheries.read more

Local ecological knowledge and scientific data reveal overexploitation by multigear artisanal fisheries in the southwestern Atlantic.

TL;DR: The decline of multigear fisheries catches is shown – combining anecdotal and scientific data – as well as changes in environmental perceptions over generations of fishermen, which show both the decline of multi-species fisheries catches and the occurrence of the shifting baseline syndrome.

Rômulo Rn Alves,Wedson Ms Souto +1 more
TL;DR: This work presents a historical view of ethnozoological research in Brazil and examines its evolution, tendencies, and future perspectives as well as suggesting research strategies that will maintain the quantitative growth observed in the recent years but foster needed qualitative improvements.

Fishers' knowledge identifies environmental changes and fish abundance trends in impounded tropical rivers.
TL;DR: The hypothesis that large dams may adversely affect small-scale fisheries downstream is reinforced and a feasible approach for applying fishers' LEK to fisheries management is established, especially in regions with a low research capacity.

Suggestions for fixing top-down coastal fisheries management through participatory approaches
TL;DR: In this paper, the potential to change conflicting MPAs into conservation areas that take into account fishers' use and knowledge is assessed based on a case study on the Brazilian coast (Paraty town).

Rediscovery of traditional ecological knowledge as adaptive management
TL;DR: In this article, the role of traditional ecological knowledge in monitoring, responding to, and managing ecosystem processes and functions, with special attention to ecological resilience, was surveyed and case studies revealed that there exists a diversity of local or traditional practices for ecosystem management, including multiple species management, resource rotation, succession management, landscape patchiness management, and other ways of responding to and managing pulses and ecological surprises.
