Abstract
This paper presents experimental results of growing – out of golden trevally (G. speciosus Forsskal, 1775) in cages using pallets with three trials including two feedings/day, three feedings/day and four feedings/day. Results showed that, after one month, the mean lengths of fish in all three trials were not statistical significant different (P ≥ 0.05), but, mean weights of fish were statistical significant different (P < 0.05) between two and four feedings/day, while no statistical significant differences found between three with both two and four feedings/day (P ≥ 0.05). After three months, the mean length and weight of fish in two feedings/day were lower than mean length and weight of fish in three and four feedings/day (P < 0.05), while the mean lengths and weights of fish in the three and four feedings/day were not statistical significant different (P ≥ 0.05). The weight variation rations and survival rates of fish were not statistical significant different between all three trials (P≥ 0.05).
