A study of the performance of Clarias gariepinus (African Mudfish) in a polyculture with Oreochromis niloticus (Tilapia), integrated with broiler chicken production was carried at the African Regional Aquaculture Centre, Nigeria. Three experimrntal treatments were utilized. Treatment I was a polyculture of C. gariepinus and O. niloticus integrated with broiler chicken production, with application of supplemental feed to fish. Treatment II was a repeat of treatment 1, except that no supplemental feed was applied to fish, while treatment III was a polyculture of the two fish species per se with application of supplemental feed to fish. Results showed that the final individual weight, individual weight gain and recovery rate were best for C. gariepinus, under treatment I. Moreover, C. gariepinus yield in treatment II was 47.7% of that of treatment I, while yield in treatment III was 15.6% and 32.7% of those treatments i and ii respectively. Furthermore the comparisons of the daily g.....
