Larval rearing of African catfish, Clarias gariepinus fed decapsulated Artemia, wild copepods or commercial starter diet

Abstract

K.B. Olurin, P.O. Iwuchukwu and O. Oladapo

A feeding trial was conducted on Clarias gariepinus larvae using three diets: decapsulated Artemia, wild copepods or commercial starter diet. On the fourth day post hatch, larvae were randomly distributed into nine plastic tanks at a density of 80 fish per tank, using a completely randomized design, and each treatment condition was triplicated. Survival was highest in fish fed decapsulated Artemia, and least in fish fed commercial starter diet. Growth rate , specific growth rate and final weight were highest in fish fed decapsulated diet, while the least growth were observed in fish fed commercial starter diet. Growth performance and survival were intermediate in fish fed copepods. The same trend for survival and growth performance was observed for length measurements (p<0.05). It is concluded that inert diet may not be suitable for first feeding of C. gariepinus larvae.
