%X The species and size composition, relative abundance and biomass were studied in fish assemblages inhabiting various habitats of the Central Delta of the Niger River with a special regard to young-of-the-year fish. A beach fry seine, fine-meshed gill net and fry traps were used when sampling the fish in floodplain sectors Ouro Modi, Mopti and Walado Debo during November 1990, i.e. during just decreasing flood and beginning downstream migration of juvenile fish. The results of sampling were strongly dependent upon the types of habitat studied and fishing device used, as well as upon the day time during which the fishing action was performed. Altogether, 38 taxa were registered. The relative abundance and biomass (in terms of catch per one action of a 8-m beach seine) ranged 16 - 2,680 inds and 7 - 976 g, resp. The maximun values of both variables were found on a littoral shallow section of the main channel of the Niger near the village of Barigondaga. (D'après résumé d'auteur)
