More Information
Summary:The formulation and manufacture of fish feed, the principal cost factor in fish production, must be based on sound information regarding nutritional requirements if the process is to be economical. Assessing nutrient requirements from growth experiments depends on the availability of a suitable model of growth, the analysis used to identify required levels of nutrients, choice of response variables, and the feeding scheme used to deliver the target nutrient to the fish. The review examines specific elements critical in experiments designed to estimate nutrient requirements for vitamins, proteins, amino acids, essential fatty acids, and minerals. Also provided are formulations for semi-purified diets and examples of data interpretation.
