| Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. The ichthyofauna consisted of 245 species (81 families, 32 orders and 2 classes). Among the species, 50 species were... |

| Neste boletim encontram-se as informações sobre a pesca profissional e esportiva (pesca recreativa) coletadas e analisadas pelo Sistema de Controle da Pesca de Mato Grosso do Sul (SCPESCA/MS) no ano de 2014. Os dados obtidos são provenientes do pescado capturado em toda a Bacia do Alto Paraguai em Mato Grosso do Sul (BAP/MS) e vistoriado pela Polícia Militar Ambiental/MS. Foi registrado um total de 306 t de pescado, das quais 136 t (44,4%) foram capturadas pela pesca profissional (estimativa de captura) e 170 t (55,6%) pela pesca esportiva. As espécies mais capturadas pelas duas categorias juntas foram: cachara Pseudoplatystoma reticulatum (69 t, 22,6%) pintado Pseudoplatystoma corruscans (67 t, 22,1%), e pacu Piaractus mesopotamicus (43 t, 14,3 %). Os... |

| Following the decision of the European Union to enforce drastic management actions in the fishery sector, there is now a debate on the reality of the overexploitation of the major living resources. This paper firstly provides an overview of the state of the world fishery resources as it is shown by international studies. It then focus on European fisheries which are of interest for the French fleets, including those which are not managed by a TAC and quotas system. Finally, various arguments which are often used to explain the depletion of fishery resources in European waters are examined. We conclude that fishing dominates all other factors with regard to the evolution of marine living resources. |

| ABSTRACT Two Coryphaena hippurus morphotypes (dourado and palombeta) are found along the Brazilian coast and are considered by Rio de Janeiro’s fisherman and fishmongers as two different species. Furthermore, these morphotypes are commercialized under different values and suffer different fishing pressure. Therefore, a definition of their taxonomic status is an important economic and biological matter. In order to investigate this problem, allozyme electrophoresis method was undertaken for seventeen loci on 117 individuals of C. hippurus sampled at Cabo Frio/RJ (Brazil). The data indicate homogeneity between the morphotypes gene pools. Nevertheless, differences were found for genetic variation among dourado and palombeta, especially due to alcohol... |

| Fishing plays an important role in the Senegalese economy and society. Indeed, it is a multipurpose activity that contributes towards reducing the balance of payments deficit, reducing unemployment and satisfying the protein needs of the population. Despite its importance, the fishing sector is facing serious socioeconomic disequilibria, which has lead to overfishing and the use of harmful methods of production. This, in turn, has resulted in the shortage of supplies to local markets and a reduction in protein intake for populations dependent on fishing. Furthermore, the strong tendency to export Senegalese piscatorial products has led to a shift in focus of the fishing effort from locally consumed species (pelagic) to export oriented ones (demersal),... |

| Marine protected areas (MPAs) are defined as “Any area of the littoral or subtidal terrain, together with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by law or other effective means to protect part or all of the enclosed environment” (Kelleher and Kenchington, 1992). This definition includes intertidal reserves, as well as areas for the protection of shipwrecks and archaeological remains. Marine protected areas are designated to conserve the diversity of life according to the three aspects of Biodiversity: ecosystems diversity (habitats and species), species richness and genetic diversity. Also MPAs play a key role in promoting sustainable development. They are designed to enhance the... |

| Wetlands in most parts of the world are under threat of over-exploitation partly because their socio-economic value is not well known. Yala Wetland, the largest freshwater wetland in Kenya, with a large part of it bordering Lake Victoria’s shoreline, faces even greater threats of extinction. This wetland measures about 17,500 ha and is host to a number of indigenous fish species, animals and plants which are exploited by the local communities for subsistence and commercial purposes.There has been pressure to reclaim portions of this wetland for agricultural activity. So far, 2,300 ha has, indeed, been drained for commercial agriculture. Furthermore, it is difficult to control effort in the exploitation of the remaining wetland resources since the... |
