Abstract: 343 specimens of Sarotherodon melanotheron melanotheron are sampled from March 2017 to February 2018 with carp nets. They are sexed, weighed and measured. This operation made it possible to obtain size distribution frequency, allometric coefficient (b) and condition factor (k) modal class is [17.78-19.03] for each of the two sexes in sector VI. In the females of Ayame 1 artificial lake and Aby lagoon, modal class is [19.04-20.29] while in the males it is [20.30-21.55]. Only in lagoon males, cases of positive and isometric allometric growth appeared. Positive allometric growth is obtained in males during short dry season (b=3.23) and short rainy season (b=3.07) in Aby lagoon. In sector VI, males of the flood season had a positive allometric growth (b=3.04) while it was isometric in rainy season (b=2.99). As for condition factor, it was greater than 1. In conclusion, species adapts to any environment but with growth favorable to weight in males in lagoon.
