dc.description.abstractFragments of Gracilariopsis heteroclada weighing 10 g each were inserted in a polypropylene rope, suspended at different depths (25 cm, 50 cm and 100 cm below the water surface) and cultured with Lates calcarifer fingerlings (22-25 cm long and 158-252 g) in floating net cages from April to October. After seven months of culture, the specific growth rate of G. heteroclada was found to be influenced significantly (p ≤ 0.05) by the interaction of three factors: sea bass, water depth, and month of culture. Highest growth rate of Gracilariopsis heteroclada was recorded at 25 cm below the water surface during the month of April unaffected by the presence or absence of sea bass; while the lowest growth rale was observed at 100 cm during the months of September and October in the absence of sea bass. Approximately, 172 (dry) g m-2 mo-1 is produced from this culture system. The average length and weight of Lates calcarifer at the end of seven-month culture period was 35-39 cm and 565-741 g, respectively. Percentage weight gain/cage was 195-258, survival rate was 92-100%, and total fish production per cage was 6,780-9,637 g.en
