The feeding experiment was designed on the basis of food allowance rather than on feed formulation. Food allowances are fixed in an attempt to provide the desired amount of nutrients per body mass of fish per day (g* kg −1 * d −1 or J* kg −1 * d −1 ). Therefore, the initial determination of optimum feeding ration is not required, and utilization of neutral feed complement (e.g. cellulose) is unnecessary. Data interpretation for such a design study is presented by a sample experiment for protein‐energy requirements of a tilapia species, Sarotherodon melanotheron. The interrelationships of commonly used indices for growth and nutritional efficiency are discussed.
