The proximate composition of some wild tilapiine fishes in Epe lagoon, Lagos, Nigeria was analyzed. The species were Sarotherodon melanotheron, Tilapia guineensis, Tilapia mariaei, Sarotherodon galileaus and an ecotype cichlid popularly called ‘wesafu’. Major nutrient compositions of raw muscles like protein, fat, moisture and ash were determined. Proximate compositions were found to be varied among the species. Protein was determined in Sarotherodon melanotheron (19.13%), T. guineensis (18.71%), T. mariae (18.08%), S. galileaus (18.34%) and ‘wesafu’ (21.80%) respectively. Lipid content was recorded as 0.82%, 0.40%, 0.60%, 0.65%, and 0.90% for the tilapia species. The highest level of moisture content was found in T. guineensis (81.70%) and the lowest was in ‘wesafu’ (78.50%). The percentage of ash content was highest in S. galileaus and S.melanotheron (1.75%) and lowest in T. guineensis (1.00%). The present study revealed highest protein content in the ecotype cichlid, wesafu (19.22%) and lowest value in T.mariae (18.08%) while fat was highest in ‘wesafu’ (0.90%). The results of this study reveal the nutritional significance of the ecotype cichlid, ‘wesafu’ above other cichlids of the lagoon.
