Relationships between fish weight and length, otolith length and fish length, and otolith weight and length were analysed in
two cichlid fish species, Coptodon guineensis (Günther, 1862) and Sarotherodon melanotheron Rüppell, 1852 (Perciformes,
Cichlidae), collected in two lakes in southern Benin (western Africa). The analysis of covariance (ANCOVA) was used to
detect differences in the relationships between the specimens of the two species collected in the two lakes. To the authors’ best
knowledge, this study represents the first reference available on morphometric relationships for C. guineensis and S.
melanotheron in the investigated area.
