Fish species, catch per unit effort (CPUE) and size structure in the lower Bandama River (Côte d’Ivoire, West Africa)
Abstract
This study helped to fill the information gap on some characteristics of the fish and fish fishery on the Bandama River. Data were collected using the fishermen catches.
It gives information on species composition, CPUE and size structure of fish in three localities of the Lower Bandama River. 44 species belonging to 19 families were recorded during this sampling. The locality of Tiassalé is the richest with 39 species followed Singrobo (37 species) and N’Zianouan (33 species).The family of Cichlidae (20% of catches) and Chrysichthys nigrodigitatus (15% of species) dominate catches throughout the area. The CPUE average values varied from 6.36±2.81kg/trip at Tiassalé to 5.41±1.7kg/trip at N’Zianouan and are generally higher in all localities in the drop season. The minimum and maximum average sizes are higher at Tiassalé which has 22.59% of large individuals. Furthermore, the modal classes vary from 11.25 to 17.95cm at Tiassalé, Singrobo and N’Zianouan. This study on fishing in Lower Bandama River has provided information on the exploitation of fishes at Singrobo, N’Zianouan and Tiassalé.
