| Most of the fishes living in the lagoons do not spend all their time in these brackishwaters. Sometimes, they go back to the river to spawn as in the case of freshwater fishes like Chrysichthys nigrodigitatus. Others like marine fishes (e.g., Ethmalosa jimbriata) feed or reproduce in lagoons for a time. Even true lagoon fishes are generally able to live in freshwater and/or in marine water. This is the case for two brackishwater tilapias, Sarotherodon melanotheron and Tilapia guineensis. Both are present in lagoons from Senegal to Congo (formerly Zaire). S. melanotheron is present in marine water near Dakar, Senegal, and in some freshwater lakes in Cote d'Ivoire. 1: guineensis is also present in freshwater in Cote d'Ivoire. |

| Coastal lagoons form an integral part of marine fisheries and provide important spawning and nursery grounds for many fish species. The economic contributions of lagoon fisheries have not been given adequate consideration by fisheries authorities. Ghana's 550-km coastline includes over 90lagoons. These lagoons and their wetlands provide valuable products and services, which include supporting the fisheries, absorbing floodwaters and protecting biodiversity. They also serve as roosting, nesting and feeding sites for many species of birds. Through the support of the World Bank and the Global Environmental Facility, Ghana has designated five coastal wetland areas as Ramsar sites due to their importance as fishing areas and as roosting, nesting and feeding... |

| Dans le présent travail, les profils lipidiques des acides gras du pétoncle Flexopecten glaber récolté dans la lagune de Bizerte pendant le mois de mai 2007 ont été déterminés. Les pourcentages des différents groupes d’acides gras dans les organes (manteau, muscle adducteur, gonade, branchies et glande digestive) ont été calculés. Les résultats de la chromatographie en phase gazeuse ont révélé des pourcentages élevés en C20:5n-3 et en C14:0 et le rapport C22:6n-3/C20:5n-3 (DHA/EPA) est inférieur à 1, au niveau de la glande digestive du bivalve. Ceux-ci nous ont permis d’en déduire que le régime alimentaire de ce bivalve est essentiellement basé sur les diatomées. Les pourcentages les plus élevés des acides gras polyinsaturés de la série n-3 (EPA et DHA... |
