Diversity of Fresh Fish Sold at the Carriére Landing Stage Located Along Lake Sélingué in Mali

Lake Sélingué is one of the main fish production areas in Mali. The fish are concentrated at the Carrière landing stage, in the Prefecture of, before being transported to urban centers. The purpose of this contribution is to establish the list of fresh fish landed at this landing stage, coming from the waters of Lake Sélingué. The study was spread over a period of 10 months with one outing per month. Landed fish were identified on site and then counted by species to determine specific diversity, frequency and groups based on occurrence. The results showed the presence of 56 species of fish distributed in 17 families and 35 genera. The Mormyridae family with 10 species is the best represented in the landing stage, followed by the Alestidae, Cichlidae, Cyprinidae and Mochokidae with 6 species each. Eight (8) species represented 71.92% of the catches, the most frequent of which were Chrysichthys auratus, Sarotherodon galilaeus and Coptodon zillii. Mochokus niloticus and Marcusenius cyprinoïdes are added to the list of fish recorded in the area of Lake Sélingué. The fish consisted of 50% constant species, 17.86% incidental species and 32.14% accidental species. The specific diversity index is 4.19 with a maximum diversity of 5.80. Given the great diversity of species, the Carrière landing stage could serve as a reference site for research and conservation of ichthyological diversity.
