Abstract: The feeding periodicity and dietary changes of Haplochromis graueri, H. olivaceus, H. nigroides and H. kamiranzovu, 4 endemic species from lake Kivu, were investigated by determining the stomach fullness index at intervals of 3 hours over a 24-hour cycle. These 4 species showed 2 types of daily feeding activity rhythm both characterised by a major food intake at daytime. A first type of bimodal feeding rhythm with the first peak situated in the morning between 6.00 a.m. and 12.00 a.m. and a second one in the evening between 3.00 and 9.00 p.m. characterizes H. graueri, and H. olivaceus. H. kamiranzovu and H. nigroides on the other hand showed a unimodal feeding rhythm with a single peak situated in the afternoon between 3.00 and 6.00 p.m.
