Abstract
Two experiments were performed in order to evaluate two feed stuffs, namely fermented fish silage (FFS) and boiled full-fat soybeans (BFS) as alternative protein sources for fish meal (FM) or fish meal replacers in Nile tilapia feeds. Both FFS and BFS performed well up to 50% substitution of FM without a significant loss in performance reared fish. These results also indicated that FFS is a promising feed ingredients for substituting fish meal at 25-50% dietary protein in Nile tilapia diets.When different levels of boiled full-fat soybeans (BFS) were tested in the next experiment, similar results were obtained. Among this tested levels, substitution of fish meal with 25% dietary BFS was possible without any significant reduction in performance parameters The utilization of FFS or BFS as the only dietary protein source (100%) significantly reduced growth performance of the tested fish.
