dc.description.abstractMale and female sea bass (Lates calcarifer Bloch) from 1982 wild-caught juveniles reared in floating net cages matured at about 2.0–2.5 years (mean body weight =1.1 kg; mean total length = 42.0 cm) and 3–4 years (2,7 kg; 54.5 cm), respectively. To monitor the occurrence of natural spawning, thirteen females were paired with twenty-eight males in a separate net cage in 1986. A “hapa” net with the same dimension as the net cage was installed to retain the spawned eggs. Spontaneous spawning occurred from June to October. The monthly total number of eggs collected varied from 393,000 to 60 million. Spawning appeared to be related to the lunar phase. Of the 26 recorded spawnings, seventeen took place within four days before or after the first quarter moon, while nine occurred within five days before or three days after the last quarter moon. All spawnings were observed between 1900–2300 hrs. The results demonstrate the feasibility of breeding sea bass in floating net cages, which is relatively cheaper and simpler than other existing methods.en
