Condition factors and growth trends indices such as allometry coefficients are decisive fisheries management
tools that evaluate the well-being of fishes, their establishment and the quality of their habitat. We investigated
the condition factors and length-weight relationships of a freshwater tilapine cichlid, Sarotherodon galilaeus,
that has naturally colonized the artificial lake of Ahozon (South-Benin). S. galilaeus individuals has been sampled
every month in the “aquatic vegetation” and in the “open water” habitats with seines, cast nets, gill nets and
hooks. This species dominated Lake Ahozon and made about 85.21% of the fish community. Fish sizes showed
