The actors and fishing gears on the Fresco lagoon (Côte d’Ivoire, West Africa) were studied from August 2018 to July 2019 by administering questionnaires to fishermen, interviewing them and observing them during their various activities. The fishing practiced on this lagoon is of the artisanal type. A total of 59 fishermen were surveyed, including 49 Ivorians (83.05% of all fishermen), with a predominance of Godiés (62.71%) and 10 Malians (16.95%), with a majority of Bozos (10.17%). All are male. Most of them are professionals (55.93%), adults (59.32%), have primary school education (49.15%), are married with family responsibilities (74.58%), have personally financed their activities (82%) and are Christians (71.19%). They are not united into cooperatives. Materials used include longlines, hawks, gillnets, wire traps and barrage nets. The density of fishermen is relatively low (2 to 4 fishermen/km2). Motorized pirogues, bamboo traps and ichthyotoxins are prohibited. Unfortunately, materials with mesh sizes below regulatory standards are used. These results constitute a database for an efficient management of the fisheries resources of the Fresco Lagoon.
The aim of this study is to make the qualitative and quantitative inventory of the fish population settlement of Kaby Lake. It was conducted every month from May 2017 to April 2018 on Lake Kaby in Bongouanou, in Côte d'Ivoire. Its objective is to characterize the fish fauna. To do this, experimental fisheries were made there, by means of a battery of six monofilament nets of meshs 15, 20, 25, 30, 40, and 60 mm. In this context, four (4) species, divided into three genera and three families, including Oreochromis niloticus (an introduced species), have been inventoried. The results of the study show that the fish population of Lake Kaby is dominated by Clariidae, with two (2) species accounting for 50% of the total fish fauna of this lake. In addition, the Cichlidae and Channidae families are monospecific, representing 25% of the population for each. Finally, this stand remains predominantly dominated by the species Oreochromis niloticus with 90.5 %, representing 76.43 % of the total biomass. Thys study allowed to make the first qualitative and quantitative inventory of the fish population settlement of Kaby lake. These results will serve as a reference for future investigations of this fish fauna and the development of appropriate arrangements to ensure the protection and sustainable exploitation of the services of this lake environment.
