Abstract

The experiment was aimed to know dietary protein requirement and the effect of dietary protein levels on juvenile red snapper (Lutjanus argentimaculatus). The experiment was conducted in 18 polycarbonate tanks, with each 30 liter volume. All tanks were equipped with aeration and flow through water system to maintain good water quality. Hatchery produced juvenile red snapper of 9.4 ± 0.1 g average body weight and total length of 7.7 ± 0.4 cm was randomly selected and 10 fish was stocked in each tank. Fish were fed with experimental diets contained different levels of protein, i.e., 32, 36, 40, 44, 48, and 52%.The experiment used completely random design (CRD) in triplicates. Results showed that dietary protein levels influenced growth, feed efficiency, feed intake, body protein content, and protein retention of juvenile red snapper (p<0.05). The highest weight gain (263.7%) was found on fish fed diet with 40% protein. Based on the growth and feed efficiency data, it was concluded that dietary protein requirement for juvenile red snapper was 40%.

Abstract

ω-3 HUFA are essential fatty acids for marine fish. Deficiency of these essential fatty acids is responsible for high mortality, low growth rate, incomplete formation and disfunction of swim bladder. This experiment was conducted to know dietary ω-3 HUFA requirement for growth of humpback  grouper juveniles.  Juveniles (9.8-10.3  g) were reared in 100 l of polycarbonate  tank with density of 12 juveniles/tank for 8 weeks with flow through system. The levels of ω-3 HUFA (EPA +DHA) supplementation in the test diet  were 0.0, 0.5, 1.0, 1.5, 2.0  and 3.0%. The results showed that the levels of ω-3 HUFA affected the growth and feed efficiency of humpback grouper juveniles (P<0.05). The growth of juveniles fed diet with 0.0-3.0% ω-3 HUFA were  significantly different with the growth of juveniles fed diet with 0.0 and 0.5% ω-3 HUFA. The growth of juveniles fed diet with supplementation levels of ω-3 HUFA at 1.0,  1.5,  2.0,  and 3.0% were 182.2, 168.5, 183.4, and 189.4%, respectively. Whereas supplementation of  ω-3 HUFA at 0.0 and 0.5% resulted the growth of  114.9 and 139.6%, respectively. These results indicated that the requirement of ω-3 HUFA for growth of humpback grouper should be around 1.0% in diet.ω
