ARTIFICIAL FERTILIZATION IN CATFISH

ARTIFICIAL FERTILIZATION  

       Artificial propagation through hormonal treatment and stripping under controlled environmental condition in the hatchery had become a necessity to ensure mass production of fry and fingerlings of the African catfish (see section 6.2). This is the current status of fish seed production in Nigeria. The procedure has been generally standardized as a synthesis of local experience, trial and error as well as from literature and largely from the Manual on Catfish Hatchery and production which has become the filed guide for Nigeria catfish breeders. Depending on available resources, infrastructure facility and experience of the hatchery manager, the standard procedure, for convenience, had been classified into small (cottage), medium (indoor) or large (flow-through and water recirculation) hatchery production and management.
