The growth response, survival and feed utilization of hybrid catfish (Heteroclarias) under different feeding levels were evaluated for 12 months. Methodology: The experiment was carried out at the Department of Fisheries and Aquatic Environmental Management, University of Uyo, Nigeria using 9 tarpaulin tanks of 1 M3 volume. The study employed completely block design with three feeding levels (FL), 1.0% Fresh Body Weight (FBW) of fish (FL1), 1.5% FBW (FL2) and 2.0% FBW (FL3) as treatments. These were replicated three times at a stocking density of 75 fish m2. The feeding rate was adjusted monthly with increase in body weight. Sampling of fish was done monthly by draining whole water from all tarpaulin tanks. Results: Result shows that, there was no significant difference (p>0.05) for mean final weight, mean weight gain, specific growth rate and daily weight gain for FL1, FL2 and FL3, respectively. Feed conversion ratio at FL1 was significantly different (p<0.05) from FL2 and FL3. However, protein efficiency ratio showed no significant (p>0.05) difference among the feeding levels. Survival rate showed significant difference (p<0.05) among the feeding levels and the values increased with increasing feeding levels. Conclusion: On the basis of growth response and nutrient utilization data obtained, feeding hybrid catfish (Heteroclarias) at 1.5% body weight per day is recommended for raisinghybrid catfish at reduced cost of production.]]>Suleiman, M.A. and R.J.
