Integrated broiler chicken-fish culture trials were conducted simultaneously at the D'joumona National Fish Farm and rural areas in Congo. The principal objectives were estimation of the optimal number of chickens for pond fertilization and the economic aspects of such integrated systems. Five hundred and fifty-six kg of Nile tilapia (Oreochromis niloticus) were harvested from six ponds (total 0.44 ha) after 165 days. The fish stocking density was 2.2 fingerlings/sq m. Extrapolated net fish production ranged from 72 kg/ha/year (control ponds with no chicken manure) to 2,971 kg/ha with 10 chickens/100 sq m of pond. There were five chicken production cycles/year of 66 days each. Some 924 kg of broilers were produced. These trials, highly preliminary and the first of their kind in Congo, indicated that integrated broiler chicken-fish culture was not yet economically viable, but recommendations are made to improve this.
