Basin-scale planning is needed to minimize impacts in mega-diverse rivers
We analyzed fishermen's local ecological knowledge (LEK) about the feeding habits, trophic interactions, habitats, fishing grounds, migration, and reproduction of nine coastal fishes in Búzios Island, southeastern Brazilian coast. interviewed 39 fishermen using standardized questionnaires. Fishermen's LEK on habitat use interactions for studied agreed with scientific literature, allowing organization reef pelagic food webs. The mentioned that submerged rock formations would be important...
The long‐term impacts of large hydroelectric dams on small‐scale fisheries in tropical rivers are poorly known. A promising way to investigate such is compare and integrate the local ecological knowledge (LEK) resource users with biological data for same region. We analyzed accuracy fishers' LEK dynamics environmental changes Lower Tocantins River (Brazilian Amazon) downstream from a dam. estimated through interviews 300 fishers nine villages collected 601 fish landings five these villages,...

Abstract This study aimed to link basic ethnobiological research on local ecological knowledge (LEK) the conservation of Brazilian streams, based two case studies: original data LEK fishermen about freshwater fish in Negro River, Amazon, and previously published farmers relationship between forest streams Macabuzinho catchment, Atlantic Forest. Information was obtained from through interviews using standard questionnaires containing open‐ended questions. Informants for interview were...
Dusky grouper (garoupa, Epinephelus marginatus) is an important catch for several artisanal small-scale fisheries along the Brazilian coast. It a sedentary, monandric, and late maturing protogynous species, which makes it vulnerable to overharvesting even though mainly caught through hook line or spear fishing free diving. Lack of information on ecology biology this species in Brazil astonishing. Much found literature concerns Mediterranean dusky groupers. Studies compiling local knowledge...
Abstract This study uses the socio-ecological resilience concept to compare two categories of fisheries co-management in Brazil: Extractive and Sustainable Development Reserves. Ecological was estimated by indicators: reserve areas, human density existence buffer zones around reserves. Indicators for social-resilience were grouped categories: flexibility (assessed livelihood diversification resources exploited) capacity organize local/governrnenta1 demand creation, fishing management rules...
Tropical fisheries, which are considered multi-species, may show selectiveness. We analyzed the degree of selectivity fish catches in 46 sites along Amazon basin through percentage biomass corresponding to most caught species. Amazonian fisheries were moderately selective, as 54% directed more than a quarter fishing effort one species and 87% half was five Commercial selective subsistence fisheries. Eleven (nine them migratory) have received pressure studied regions catch composition...
Analysis of Brazilian fishers' classifications 24 marine (Atlantic coast) and freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify mainly through generic names (primary lexemes), while riverine Amazonian typically them binomials. The similarity seems to contribute detailed folk taxonomy used by fishers. High‐ranking groups called "relatives" or "cousins" are sorted in terms similarities habitat, diet, morphology and, secondarily, behavior. general...
Abstract In this study, we sought to investigate the biology (diet and reproduction) ethnobiology (fishers knowledge fishing spots used catch snappers) of five species snappers (Lutjanidae), including Lutjanus analis, synagris, vivanus, Ocyurus chrysurus , Romboplites saliens at sites along northeast (Riacho Doce, Maceió in Alagoas State, Porto do Sauípe, Entre Rios Bahia State) southeast (SE) Brazilian coast (Paraty Rio de Janeiro cities Bertioga, São Paulo State.). We collected 288...
Although fishers' knowledge has been recently considered into management programmes, there is still the need to establish a better understanding of perceptions and cognition. Fishers can provide novel information on biology ecology species, which potentially be used in fisheries. The fishers have how they classify nature empirically based. It common, for example, observe that taxonomy often represented by generic level, one hierarchical categories folk classification somewhat analogous...
Abstract The local ecological knowledge (LEK) of fishermen has been applied to reconstruct temporal patterns resource abundance and assess exploitation, especially in tropical ecosystems. Protected areas (PAs) are the main conservation measure Amazon, but their efficacy improve fisheries is poorly known. goal this study was apply fishermen’ LEK evaluate changes composition exploited fish species among three different categories PAs Tapajós River, Brazilian Amazon. We interviewed 203 fishers...
Abstract Protected areas are one of the main tools for biological conservation worldwide. Although they have contributed to an increase in fish abundance and alleviated impacts fishing on marine ecosystems, protected freshwater ecosystems less well known. We compared productivity assemblage descriptors two distinct designated sustainable use natural resources unprotected area Tapajós River, Brazilian Amazon. Two hypotheses were tested: (1) fishers from higher catch per unit effort than those...
