| Resume | The global objectives of this campaign were to assess biomass and map the distribution of stocks of small coastal pelagic fish from Côte d'Ivoire, Ghana, Togo and Benin. The study was carried out with the help of hydroacoustic method. Besides, one of the other objectives was to describe the hydrographic conditions in the area during 3 days in 2012. It was found that the fish density was rather less in comparison with Nansen’s survey (2002–2006). However, it should be noted that both researches were made during different time periods. The analysis of the obtained data has shown that Ilisha africana is the most important pelagic fish. This species was caught by most of the fishermen using non-motorized boats. The main pelagic species biomass is 3490 tons, including biomass of Ilisha africana that equals 310 tons, while the other species of pelagic fish are 3180 tons. Apart from Ilisha africana, there were other pelagic fish such as horse mackerel, mackerel and barracuda. Some bottom fishes were inaccessible. This study should promote more effective control of fishery at the continental shelf. |
| Mots clés | continental shelf, pelagic fish, hydroacoustic methods, Ilisha africana. |
