In the Congo, Clarias gariepinus (catfish) is traditionnally fished in the numerous aquatic ecosystems. Fish farming-which could play a significant role in the national economy, particularly by improving protein self-sufficiency, is still in its infancy. However, fish feed represents a major constraint on the development of this sector. This study aims to evaluate the effect of a local feed (XXX) on zootechnical performance and to assess the impact of seasonal variations on Clarias gariepinus (Burchell, 1822). To do this, an experiment with three repetitions (dry season, rainy season, and the intermediate season) was conducted over 56 days at the SAPE company's premises in the village of Léfini (Republic of Congo). For this, for each season, a total of 150 juveniles with an average weight of 10.79 ± 0.48 g; 10.98 ± 0.5 g and 10.48 ± 0.26 g were placed in above-ground cylindrical tanks. In Clarias gariepinus individuals fed during the rainy season, the final average weight was 195.36 ± 5.53 g, the daily weight gain (DWG) was 3.3 ± 0.09 g/day, and the average specific growth rate (SGR) was 4.96 ± 0.08 %/day. For Clarias gariepinus individuals fed during the dry season, the final average weight was 168.16 ± 5.35 g, the DWG was 2.82 ± 0.09 g/day, and the average SGR was 5.17 ± 0.09 %/day. For Clarias gariepinus individuals fed during the intermediate season (dry and rainy seasons), the final average weight was 184.43 ± 5.55 g, the DWG was 3.1 ± 0.1 g/day, and the average SGR was 5.04 ± 0.09 %/day. The food and temperature variation affect the expression of better zootechnical performance in Clarias gariepinus.
