Controlled hatchery production of African catfish,Clarias gariepinus(Burchell): an overview

摘要

AbstractIn order to promote the successful supply and satisfactory survival of African catfish,Clarias gariepinus(Burchell), it is advocated that the fish be reared in hatcheries until they begin air breathing. Research conducted over a number of years to develop culture technology for intensive hatchery rearing to the stage of air breathing is brought together here as an overview. In particular, the definition of early development stages is considered as well as induced spawning, egg incubation, larval rearing and fry rearing.
