Abstract:
The present study aims to evaluate the diversity of fish populations in urban and peripheral lakes of the city of Yamoussoukro. This study was carried out on 8 lakes (5 urban and 3 peripheral) during 08 sampling campaigns between December 2022 and February 2024. The collection of fish from experimental fishing was carried out using gill nets, creels and hawks. The ichthyofauna inventory made it possible to identify 18 species of fish divided into 9 families and 5 orders. Fish populations are more diverse in the peripheral lakes (16 species) especially in lake 4 (16 species) than in the urban lakes (7 species). The frequencies of occurrence of ichthyofauna show that Oreochromis niloticus and Coptodon zilii are the species most encountered in the lakes. Analysis of the diversity of fish populations in the reserve shows that fish populations are less diverse, stable and balanced.

Keywords: Fish populations, Urban lakes, Peripheral lakes, Yamoussoukro.
