Abstract
The use of Cockroach (Periplaneta americana) meal was studied to ascertain its digestibility and effect on growth performance of Clarias gariepinus. A 40% protein basal and test diets using fish and cockroach meal respectively with inert biomarker at 70:30% were fed for 42 days to Clarias gariepinus of average weight 29.22±0.18g. Catfish response to diets in terms of growth parameters revealed the following for reference diet fed and basal diet fed fish: weight gain (52.59g vs. 36.31g); specific growth rate (2.46%/g/day vs. 1.91%/g/day); feed conversion ratio (1.71 vs. 2.13); and percentage weight gain (181.44% vs. 123.35%). Apparent digestibility values of test diet were higher significantly (P<0.05) than basal diet. Digestibility coefficient in reference diet fish and basal diet fish showed that: protein (88.48% vs 87.01%); dry matter (87.35% vs. 86.82%); energy (86.88% vs. 85.48%); and fat (39.67% vs. 27.75%). African catfish responded positively to CIM diet with improved growth performance up to 30% inclusion level. Apparent digestibility of the CIM diet was superior to the fishmeal reference diet.
