The objective of the study was to determine the hatchability rate of African cat fish eggs under artificial condition in Adamawa State, the guinea savannah zone of Nigeria. The female fish was artificially induced using ovaprim at 0.2ml in the cool hours of evening. The eggs were stripped in the morning hours after 12 hours of stimulation and were fertilized externally with sperms collected from the male fish. Fifty percent (50%) of the eggs were observed to have hatched successfully within 12 hours though; the entire system ran out of water supply in the middle of the night. This led to the death of all the fry and prevented all the other eggs from hatching resulting to 0% fingerlings. The quality of water used was not ascertained because, it was not tested and the source unknown. The climatic conditions were observed to be favourable because, the work was performed during the raining season between August and September, 2017. It was observed that, in most of the African catfish hatcheries, fry ‘come out’ from eggs under an artificially controlled condition in commercial numbers. Water quality forms part of the most important factors in achieving high hatchery success rate. These fry grow into fingerlings and they later become juveniles. These fry need consistent good food provided in sufficient quantities at regular intervals for smooth transitional growth. A lot of uncertainties have been linked to the propagation of African Catfish and this may be probably due to inadequate knowledge of the fish. Therefore, a successful hatchery relies on efficient facilities and equipment that match excellent up to date technical know-how, standard procedures, and dedicated and skilled personnel.
