Abstract
The study was conducted to determine the growth performance and survival rate of African catfish (Clarias gariepinus) fry fed with freshwater mussel meal during 21 days of nursing period. The experimental treatments were; T1 (Commercial feeds), T2 (80% freshwater mussel + 20% cornstarch), T3 (60% freshwater mussel + 40% cornstarch). Result of the study showed that African catfish fry fed with commercial feeds (T1) obtained the highest survival rate (94.67%) and final total body length (5.26 cm). On the other hand, African catfish fry fed with 80% freshwater mussel meal (T2) obtained the highest gain in weight (1.34 g), average final body weight (1.36 g), absolute growth rate (AGR) (0.06 g/day and specific growth rate (SGR) (8.33%). While African catfish fry fed with 60% freshwater mussel meal (T3) obtained the lowest final total body length (4.78 cm), gain in weight (1.10 g), average final body weight (1.11 g), absolute growth rate (AGR) (0.05 g/day), and specific growth rate (SGR) (8.15 %) but highest in survival rate (80%) than treatment T2 (61.33%). Despite these differences, analysis of variance showed no significant difference in all treatment groups. Based on the result of the study, the performance and survival rate of African catfish fry fed with commercial feeds (T1) had no significant difference from fry fed with freshwater mussel meal (T2 and T3)
