Abstract


The diet of Hemichromis fasciatus (Perciformes, Cichlidae) was studied in the lake dam of Ayame 2 (Côte d'Ivoire) from September 2015 to August 2016. A total of 141 specimens were captured using gill nets and hawks. The relative importance of food index has been calculated to assess the relative abundance of the preys. The standard length of fish varied between 70 mm and 250 mm. The global percentage of emptiness and intestinal coefficient mean were 23.40 % and 1.35 ± 0.48 respectively. The food spectra constituted of fishes, insects, arachnids and plants debris showing that this species an omnivorous fish with predatory fish tendency. The comparison of the food habits between size ranges (LS ≤ 110 mm and LS ˃ 110 mm) did not show any significant difference. But, a significant variation of the diet according the sexes and seasons was observed.
