African catfish, <i>Clarias gariepinus </i>(Burchell, 1822): An ideal candidate for biowaste management

Abstract

Juveniles of African catfish, <i>C</i>. <i>gariepinus </i>were fed with different biowastes procured from various stations viz., slaughter houses, poultry sheds, fish markets, hotel kitchens and ware houses. Maximum growth was obtained in the fishes fed with poultry wastes and minimum in the fishes fed with warehouse waste. Total protein, fat, and dry matter contents were high in poultry and butcher wastes fed fishes. Culture of catfishes in controlled conditions by feeding biowaste is an alternative step to control the prevailing wide spreading culture practices of African catfish, which poses a threat to inland aquatic biodiversity. The present approach is ideal for recycling biowastes to fish protein and to keep our environment clean and hygienic.
