Abstract: Based on 195 samples from the Bia River (Ivory Coast-Ghana) on which a hydro-electric dam was built in 1959, the diet of Mormyrops anguilloides was studied in relation to fish size, locality and season. A feeding index was computed by combining the occurrence and weight percentages of the items identified in the stomach contents. In the lacustrine environment, M. anguilloides mainly fed on fish, especially on tilapias (Cichlidae) Sarotherodon melanotheron and Tilapia spp., whereas in riverine localities two groups of preys (Crustacea and fish) were mainly eaten. This dietary shift is statistically significant. In the lake, the dirt varied significantly with size; young fishes preyed on benthic invertebrates, mostly aquatic insects whereas larger fishes were exclusively piscivorous. Significant variation in the diet was observed between seasonal samples examined from the lacustrine environment.
