| Les implications de la biodiversité sur les pratiques de pêche dans les milieux continentaux en général etestuariens en particulier, sont relativement peu étudiées au Sénégal. les connaissances accumulées sur la bio-écologie des espèces et les modes d’exploitation utilisés par les pêcheurs artisans permettent cependant d’en tirer les grands traits. Les estuaires du fleuve Sénégal, du Sine Saloum Et de la Casamance ont des systèmes d’alimentation en eau différents. Les variations du régime pluviométrique et l’évolution de la pluviométrie ces trois dernières décennies (succession d’an.nées humides et d’années particulièrement sèches) ont influencé fortement les caractéristiques physico-chimiques de ces cours d’eau. Les espèces de poissons ont développé des... |

| The inland fishery in South Sumatra, Indonesia, is an important source of income, employment and protein to small-scale fishers. Some overall indicators, such as virtual disappearance of certain important species and continuous reduction in the size of harvested fish, indicate that the fishery is not being exploited on a sustainable basis. In this study, an evaluation of the status of the existing fish stock is undertaken, and an analytical model for identifying efficient levels of exploitation of the fishery is developed. Primary data are used to describe the current costs of fishing effort. Secondary data, combined with results of analysis of primary data, are then used to derive a supply function for the fishery. Different types of fishing gear are... |

| Topics on Lake Victoria limnology, benthic fauna, stock assessment, catch assessment survey, gear selectivity, fisheries ecology, fish parasites and marketing economics are covered. Management and conservation of the lake's fisheries and other aquatic resources are discussed. Dialogue between fishermen, scientists and administrators is stressed, measures to be undertaken are addressed and further research is recommended. |

| Neste boletim encontram-se as informações sobre a pesca profissional e esportiva coletadas e analisadas pelo Sistema de Controle da Pesca de Mato Grosso do Sul (SCPESCA/MS) no ano de 2013. 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 333 t de pescado, das quais 165 t (49,5%) foram capturadas pela pesca profissional (estimativa de captura) e 168 t (50,5%) pela pesca esportiva. As espécies mais capturadas pelas duas categorias juntas foram: pintado Pseudoplatystoma corruscans (83 t, 26%), cachara Pseudoplatystoma reticulatum (79 t, 25%) e pacu Piaractus mesopotamicus (32 t, 10 %). Os rios que mais contribuíram... |

| 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... |
