Abstract

The diet and feeding habits of the African electric catfish Malapterurus electricus in their natural habitat in Lake Kainji, and in the River Niger, downstream of Kainji dam, Nigeria, have been described and compared. The study showed the electric catfish is a voracious piscivore. It feeds on cichlids, clupeids, schilbeids and other available fish species. From the size distribution, numbers and composition of the small prey fish species examined in electric catfish stomachs, it was inferred that the powerful high‐frequency electric organ discharge volleys serve as major predatory mechanism.
