1. Actual status of fishing reserves of the Yesil River
ABSTRACT In this article, the study and prediction of the state of fish resources in the Yesil River was carried out to determine the boundary reference points of the reserve and management decisions in case they are exceeded, to ensure sustainable fisheries and preserve biological diversity. Ichthyological studies, retrospective analyses and rankings of the

2. IS POWER LISTENING TO SCIENCE? THE CASE OF ICCAT AND THE EASTERN BLUEFIN TUNA (2004-2014)
Resumo Este artigo conclui que, diante da crise internacional da gestão da pesca do atum em 2009, uma comunidade epistêmica emergiu na ICCAT e empregou esforços coletivos para lidar com problemas compartilhados e isso melhorou a eficácia do acordo em termos de recuperação dos estoques pesqueiros do atum azul. Nesse sentido, a principal questão a ser r

3. The bony fishes (Teleostei) caught by industrial trawlers off the Brazilian North coast, with insights into its conservation
RESUMO A costa Norte do Brasil é um dos pesqueiros de camarão mais importantes do mundo, com uma área total de aproximadamente 223.000 km2. No entanto, dados disponíveis sobre a diversidade de peixes capturados pela frota industrial de arrasto de portas na região são limitados às espécies com valor comercial. Essa lacuna no conhecimento sobre a fauna

4. Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil
Resumo: Nas costas tropicais e subtropicais, sobre as plataformas continentais, os recursos pesqueiros demersais são abundantes e considerados uma parcela importante do ambiente marinho. Os recursos pesqueiros demersais marinhos são capturados por diversas modalidades de pesca, muitas vezes de forma insustentável, o que vem provocando o esgotamento de seu

5. Length-based estimates of growth parameters and mortality rates of fish populations from a coastal zone in the Southeastern Brazil
ABSTRACT Small-scale fisheries in Brazil contribute to a significant share of total fish production, accessing a large variety of species. Life history parameters from these resources are important for their management and conservation, based on primary data. The objective of this article is to generate growth parameters and mortality rates of ten fish popul

6. Reproductive biology of Cetengraulis edentulus (Cuvier, 1829), the major fishery resource in Guanabara Bay, Brazil
Cetengraulis edentulus is a broadely distributed engraulid in Southwest Atlantic, currently accounting for the main fish species commercially exploited at Guanabara Bay, Brazil. This study aimed to extend the knowledge on reproduction of C. edentulus at Guanabara Bay and to test whether some descriptors of reproductive activity, especially the gonadosomatic

7. Biodiversity, distribution and abundance of shrimps Penaeoidea and Caridea communities in a region the vicinity of upwelling in Southeastern of Brazil
This study evaluated the spatial-temporal distribution of the abundance of Caridean and Penaeid shrimps during the period of two years in the coastal region of Macaé, state of Rio de Janeiro, southeastern Brazil, using ecological indices (Shannon-Wiener diversity and Pielou's equitability). Monthly samples were carried out from March 2008 to February 2010 d

8. Bio socio economic evaluation of artisanal fisheries of Barra Bonita reservoir (SP) / Avaliação biossocioeconômica das pescarias artesanais da represa de Barra Bonita (SP)
The artisanal or small scale fisheries are practiced in small reservoirs, with an operation area restricted and familiar labor. It´s common in inland waters and the fish caught is an important source of protein for people who depend on them and provide economic returns to the fisher, despite the presence of intermediaries in the marketing of fish. The Barra

9. Identification and phylogenetic inferences on stocks of sharks affected by the fishing industry off the Northern coast of Brazil
The ongoing decline in abundance and diversity of shark stocks, primarily due to uncontrolled fishery exploitation, is a worldwide problem. An additional problem for the development of conservation and management programmes is the identification of species diversity within a given area, given the morphological similarities among shark species, and the typica

10. Análise comparativa da variação genética entre os estoques cultivado e natural de Prochilodus argenteus : implicações para o repovoamento de rios
Introduction of hatchery fish in river has been the major using strategy for river fishery rehabilitation, working to attenuate river damage in short time. But there are effective risks about their efficiency and results, concerning the pool gene preservation and illness proliferation, beyond others ecologies and economics aspects.

11. EvoluÃÃo das capturas, idade, crescimento e recrutamento de espÃcies de Lutjanidae do nordeste do Brasil / Catcha evolution, growth and recruitment of lutjanidae species ocurring on northeast coast off Brazil
Lutjanid species are widely distributed on tropical and subtropical seas, occurring on hard bottom environments. Constituted by one hundred and three species, the family Lutjanidae is distributed in four subfamilies (Apsilinae, Etelininae, Lutjaninae and Paradicichtinae) by four genera (Etelis, Lutjanus, Ocyurus and Rhomboplites) where eleven species of thes

AvaliaÃÃo dos procedimentos de introduÃÃo do Pirarucu (Arapaima gigas) na regiÃo Nordeste: retrospectiva histÃrica, situaÃÃo atual e perspectivas futuras / Evaluation of procedures for submitting Pirarucu (Arapaima gigas) in the Northeast: historical overview, current status and future prospects
The national fish farming production is vastly increasing, especially in northeastern Brazil. There is currently a demand for new management techniques for native species. This is because most of Brazilian production is based on farming of exotic species. The bonytongue is a native species with great potential for farming. The bonytongue was first introduced
