| General trends in the feeding habits of the main families of Africans freshwater fishes are discussed, and dietary changes at different ages and in different seasons are described. The main conclusions reached are : feeding habits within a genus are usually similar, even over a wide distribution area, fishes grouped in some genera are specialized feeders e.g. piscivores (#Lates, Hydrocynus, Bagrus,$ etc), microphages #(Tilapia, Citharinus, Labeo)$, benthic insectivores #(Mormyrus, Marcusenius, Auchenoglanis)$ whereas other genera comprise mainly omnivores (e.g. #Alestes, Eutropius, Clarias, Schilbe, Heterotis$), ommivores and some piscivores, due to their euryphagic habits, are better able to adapt to harsh environmental conditions, generally speaking,... |
