Diversity and structure of the fish fauna of Rêverie Farm Water Reservoir at Anyama (Côte d’Ivoire)
Abstract
The Rêverie farm reservoir is an important eco-geographic area. It is inhabited by a variety of animals among them fishes that come to occupy its waters for reproduction and food needs. Reliable and basic information on these fishes is required for the sustainable management of this resource. The ichthyofauna was sampled monthly from July to December 2014. Experimental fisheries were conducted on the water body with various capture gears. A total of 820 fish samples was collected and belonging to 9 species, 6 genus and 5 families. The family Cichlidae (3 species with 1 hybrid) dominated qualitatively and quantitatively the population of this water reservoir. It was followed by the family Claroteidae (2 species). In terms of number and biomass and even in both seasons, the dominant species were Coptodon zillii, Oreochromis niloticus, Chrysichthys nigrodigitatus and hybrid (Coptodon zillii x C. guineensis). From a distribution point of view, the ShannonWeaver (H '> 2) index and equitability (E > 0.5) values calculated reflect a good organization and stability of the ichthyological population. The results will serve as references for the fish fauna and also to guide decision for the Rêverie farm reservoir.
