Larval and small juvenile catfish inhabit flotsam and the rootstocks of plants in very shallow marginal areas. They serve as veritable sources of fish production, animal protein, economic empowerment, and employment in Nigeria and globally (Annune et al 1994). This book contains comprehensive overviews and original studies focused on ecological and ecosystem functioning studies, hazards and conservation management, assessment of environmental variables affecting species diversity, also ... The results obtained expressed in mean percentage indicated that out of the three hundred and fifty (350) individual fish of each species examined, 121 (35%) fish had an empty stomach contents in Clarias gariepinus, and out of the 350 samples examined, 145 fish had an empty stomach content in Oreochromis niloticus representing 41%. Clarias gariepinus is discovered all through Africa and the Center East, and resides in freshwater lakes, rivers, and swamps, in addition to human-made habitats, akin to oxidation ponds, and even city sewage techniques.
