The growth performance was conducted using Clarias gariepinus and Clarias anguillaris obtained from 3 ecological zones namely; Argungu (Clarias anguillaris), New Bussa (Clarias gariepinus) and Yola (Clarias gariepinus) respectively, to evaluate the differences in survival and growth rates to have fast growing fingerlings for replenishing stock. Eight (8) weeks periods were taken to conduct this work using a semi-flow through a system of fish culture, under open shade containing 25 litres of plastic bowls filled with 20 litres of water, in which 20 fry each from the parental crosses and their reciprocals were randomly selected and stocked in each bowl of the 9 treatments with 3 replicates each. The growth was found to vary from each eco-zone which was highly significant (P<0.05>). Survival 70-90%, the highest mean weight gained was 106.7±21.246 (NB♂ x YY♀) while the least was 45.5±1.674 (AR♂ x YY♀) while the mean increase in length was 20.867±0.664 (NB♂ x NB♀) and 16.467±0.333 (NB♂ x AR♀) and New Bussa broodstocks are recommended for our fish farmers as they proved to have the basic potentials required in aquaculture.
