dc.description.abstractThe amount of rotifers consumed by a single sea bass Lates calcarifer larva per day (R) was examined by both the direct and by the satiation-digestion methods. In the direct method, R is estimated by the number of rotifers left in the larval tanks and larval density in the tanks, while in the satiation-digestion method R is estimated by the amount of rotifers found in the digestive tract of the larvae. In both methods, the amount of rotifers consumed by the larvae increased exponentially with larval growth. The relationship between the total length (TL) and the log-log plots of the maximum amount of rotifers eaten by a larva can be expressed by the following equations; \(R=1.799 \times TL^{4.398} (r=0.975)\) for the direct method and \(R = 4.861 \times TL^{3.432} (r = 0.907)\) for the satiation-digestion method. The relationship between TL and body wet weight (BW) can be expressed as: \(BW = 2.607 \times 10^{-4} \times TL^{3.786} (r=0.960)\) for larvae smaller than 6.5 mm TL and \(BW = 15.053 \times 10^{-3} \times TL^{2.855} (r = 0.916)\) for those larger than 6.5 mm TL. The index of satiation was almost the same for day 6(0-6), D-9 and D-12 (8.3-23%), higher range was observed in D-15 larvae. The index of daily feeding amount was comparatively higher in D-12 larvae compared to D-6, D-9 or D-15 larvae.en
