Abstract:
A protocol for rearing orange-spotted rockcod, Epinephelus suillus in
the hatchery is described. The feeding regime consisted of Chlorella,
Brachionus, Artemia and minced fish. With this regime, survival rates
at Day 24 were 19.8% in 3-ton tanks and only 7.4% in 0.5-ton tanks.
From an initial length of 1.62 mm on Day 0, larvae grew to 10.94 mm
on Day 24 and 51.4-65.1 mm on Day 60. Larval growth and survival
rate were improved when larvae were fed screened (less than 90
micro m) Brachionus during the first 2 weeks. Survival was even
better among larvae fed Brachionus until Day 35. Artemia, at a
density of 3/ml, given once daily to larvae in 24 ppt seawater
improved growth and survival.
