| dc.description.abstract | The 28 days rearing experiment was done to evaluate the growth performance of African catfish (Clariasgariepinus) fry reared with limited water flow in circular tank. The study had for treatments which were replicated thrice, namely: Treatment 1 (Control) - continues water inflow; Treatment 2-no water inflow and no aeration; Treatment 3 - No water inflow with 12 hours aeration; Treatment 4 - no water inflow with 24 hours aeration. Results of the study showed that Treatment 1 and Treatment 4 - no water inflow with 24 hours aeration. Results of the study showed that Treatment 1 and Treatment 4 have better growth performance as compared to the other treatments. African catfish reared in continues water inflow provided the the highest values in growth parameter such as average final weight at 1.040g, gain in weight at 1.008g, absolute growth rate (AGR) at 0.036g/day, specific growth rate (SGR) at 12.420% followed by no water inflow with 24 hours aeration with average final weight at 0.667g, gain in weight at 0.635g, AGR at 0.023g/day and SGR at 10.832%. The lowest values for the growth performance were from T2 for average final weight at 0.631g, gain in weight at 0.599g, absolute growth rate (AGR) at 0.021g/day, specific growth rate (SGR) 10.643%. In addition, fry subjected to the T2 had the lowest final total length of 0.631cm. In term of survival rate, the highest was observed again in T1 at 50.666% followed by T4 with 45.833% and the lowest was T2 with 36.66%. It is recommended the conduct of a study particularly on the comparison among continues water inflow, aeration with heater and no aeration with heater. A simple cost and return analysis is also significantly recommended. | |
