The fishing typology on the Buyo Lake Dam was studied monthly from July 2017 to June 2018. For this purpose, a questionary survey was administered to fishers, interviews were held with the lake managers and direct observations of the field were made. Fishing in this reservoir is of the artisanal type, practiced individually by Ivorians from non-Ivorians. A total, 215 fishermen were identified, including 70.7% Malians, 24.18% Ivorians and 5.12% Burkinabe. The fishing activity is dominated by fishermen of Bozo ethnicity from Mali (67.91%). Fishing is mostly practiced by adults ranging in age between 30 and 45 years and includes both professional fishermen and occasional. Most actors have no level of study. Only 11.54% of Ivorians have a primary level while 9.2% of non-Ivorians have done Koranic school. Gillnets are the most used catching gear. The low level of education of fishermen and the meshes below the standard they use are a real obstacle to the sustainable management of fisheries resources.
