The freshwater cichlid, Sarotherodon galilaeus (Linné, 1758) is an economically and commercially
important fisheries species that has naturally colonized and dominated a sand-dragged man-made
freshwater lake of Ahozon (South-Benin) where the species made about 85.21% of the fish community.

During

1189
individuals of S. galilaeus have been monthly sampled in the open water and in the aquatic vegetation
habitats. The study showed that S. galilaeus consumed about seventy (70) food items dominated
by algae (52.88%) composed of 28 families and 52 genera from blue-green a |
