Abstract

This experiment was conducted to study the effects of different stocking densities of Asian sea bass (Lates calcarifer) juvenile on growth and survival. The juvenile's sea bass were stocked at 4 different stocking densities with constant seven liters of filtered sea water. The treatments were including 1 juvenile/L, 5 juveniles/L, 10 juveniles/L and 20 juveniles/L with three replicate for each treatment. 30 day after hatch of juveniles were used in this experiment. The experiment lasted for three weeks. Green water (Nannochloropsis oculata) was added to each treatment to protect the juveniles from strong sunlight. These juveniles were fed Artemia twice a day in the morning and evening. The feeding was giving enough according to their densities. The results showed that there has significant difference among four treatments (P < 0.05) on growth of total length and body weight but there was no significant different (P > 0.05) on survival in Asian sea bass (Lates calcarifer) juveniles when analyses with one-way ANOVA. Juveniles which were stocked at 35 juveniles/L showed the highest growth of 1.45 ± 0.28 cm on total length and 0.059 ± 0.03 g on body weight, while the survival of this treatment was 100%, compared to other treatments. Therefore, 35 juveniles/L was the best stocking that can be suggested in juvenile rearing of Asian sea bass (Lates calcarifer).
