| Descripción: | The amino acid profile of Colossoma macropomum was determined. Indispensable amino acid levels were sim ilar to those reported in other fish species. Suitability of local. Costa Rican, ingredients as protein sources for C. macropomum was evaluated based on their pro tein content and indispensable amino acid profile. It was calculated that, in a standard diet (40% protein, 25% fish meal), blood meal, soya meal, poultry by products, meat and bone meal, and meat meal can substitute more than 80% of the fish meal. More than 40% of the fish meal can be substituted by shrimp meal, pigeon pea, cotton meal, peanut oU cake, cow pea, corn gluten and water hyacinth. As differences between amino acid profiles between fish species seem to be small, promising alternative ingredients for C. macropomum might be equally interesting for formulation of feeds for other species. Soya meal is thecurrently used ingredient with the highest potential to substitute fish meal completely. Further research is needed to determine if the use of alternative ingredients is limited by constraints such as decreased feed digesti bility, presence of anti-nutritional factors, additional production and processing costs. |
