This Book is about comparative effects of carp pituitary extract (CPE) and Ovaprim on induced breeding of African catfish (Clarias gariepinus) was carried out using eighteen broodstocks (nine females and nine males). The broodstocks were obtained from a private fish farm in Jos, Plateau State, Nigeria. Experimental fish were isolated by sex and acclimated in two holding tanks (each 1500L capacity) for two weeks. Broodstocks were fed 5% body weight with 40% protein pellet diet. Water quality parameters such as temperature, dissolved oxygen (DO), hydrogen ion concentration (pH), total alkalinity (TA) and free carbon dioxide (CO2) were monitored throughout the two weeks acclimation.
