Abstract: The diet of Synodontis schoutedeni from the lower Tsieme River was investigated according to specimen size, the sampling season and sex. Stomach contents of 195 individuals captured monthly from January 2013 to December 2014 were examined. The specimen size ranged between 50.51 and 97.12 mm, for an average of 63.73 ± 13.46. The intestinal coefficient varied between 0,054 and 2,579, an average of 1.44 ± 0.4 mm, which suggests that the intestine of S. schoutedeni has omnivorous diet. All stomachs were full, representing a vacuity coefficient of 0%. The food spectrum of S. schoutedeni mainly consisted of sand (Ip = 50.41%) and preys ni (Ip = 23.63%). Horn's Food Overlap Index (Ch) showed a similariy of fish diet according to the size, the season and the sex.
