The feeding ecology of Raiamas moorei, Enteromius kerstenii, and Enteromius pellegrini was studied as a contribution to the comprehension of the ecological functioning of Lake Kivu, especially its littoral zone. Fish specimens were collected during 68 fishing campaigns from 2007 to 2017 among which are 25 campaigns 24-h full daily cycles and 43 overnights campaigns. Morphometric parameters and gut contents of all fish individuals were sampled and analyzed. For Enteromius spp., entomophagy is the main strategy as they are revealed to feed mainly on insects while R. moorei combines two different prey categories: insect and fish. The reasons of this partial food partitioning among these three species are discussed. The observed feeding behaviors of these species indicate that they could compete with the new invader Lamprichthys tanganicanus and with some cichlids such as Haplochromis vittatus which inhabit the littoral zone.

Raïamas moorei Boulenger 1900、Enteromius pellegrini（民意调查，1939 年）和 Enteromius kerstenii（彼得斯，1868 年），基伍湖（东非）的三种鲤科鱼类的食物和摄食习惯

研究了 Raiamas moorei、Enteromius kerstenii 和 Enteromius pellegrini 的摄食生态，以帮助理解基伍湖的生态功能，尤其是其沿岸地区。在 2007 年至 2017 年的 68 次捕捞活动中收集了鱼类标本，其中 25 次 24 小时全日循环和 43 次夜间活动。对所有鱼类个体的形态测量参数和肠道内容物进行采样和分析。对于 Enteromius spp. 来说，食虫是主要策略，因为它们被发现主要以昆虫为食，而 R. moorei 结合了两种不同的猎物类别：昆虫和鱼类。讨论了这三个物种之间这种部分食物分配的原因。
