Abstract: This study aims to update the composition and the fishery production of the lake Ayamé 1.The fish were sampled from July 2017 to June 2018 with gillnets, traps, hawks, longlines, bamboo traps and seines. 9959 fish belonging to 37 species distributed between 14 families and 6 orders were during this study for a biomass of 606.002 kg. The best represented families are cichlids (8 species), followed by Mormyridae (6 species) and Alestidae (5 species). Regarding species, 7 species are best represented. This population is dominated by small individuals (81.41%).The fishing effort deployed by fishermen is 5374 trips, a production of 723488 kg or 723.49 t. The gillnet (56.76 %) is the most used fishing gears in the lake. The threat to this lake is the collapse of its fish fauna that would be subject to renewed conflict.
