Abstract
Five studies on the feeding of Tilapia nilotica in floating cages were conducted. Stocking densities of 100 to 200 fish per m 3 were used. Only commercially available ingredients were used in the feed. Results of the studies showed that diets containing fish meal, fine rice bran and copra meal had significantly better feed conversion ratios than diets with ipil-ipil leaf meal. Diets with 25% fish meal and 10% copra meal were found to be efficient and economical for T. nilotica. Chicken grower mash enriched with fish meal did not significantly differ from a diet consisting of 25% fish meal and 75% fine rice bran. Fish given moist pellets had significantly higher production than fish fed with dry pellets.
