Sea bass larvae of 4 different sizes, 2.59; 3.08; 3.75 and 4.19 mm. average total length, were put into 4 sets of five 15-litre aquariums at the rate of 1,000; 1,000; 800 and 800 fish/aquarium respectively. Five concentrations of rotifer containing 5, 10, 15, 20 and 30 organisms/ml. were fed to each aquarium. The feeding rate of each size of fish were observed hourly and then, daily consuming rate was calculated. The numbers of rotifer consumed per day were 388; 538; 1,083 and 1,643 organisms/larvae/day by the fish of 2.59; 3.08; 3.75 and 4.19 mm.TL, respectively. The relationship between total length of larvae and number of rotifer consumed was calculated to be R = 19.68 TL3.0475 individual and was plotted into a curve.
