Feeding of the larvae
was started two days
after fertilisation. The
initial larval stages of
the three species were
fed with Chaetoceros spp.
(20,000–40,000 cells ml-1).
The latter larval stages of
H. scabra were fed with
grounded shrimp pellets
and fine paste of Sargassum
spp. The larval stages
and juveniles of P. violaceus
and C. quadrangularis
were fed with Chaetoceros
spp. (40,000 cells ml-1)
continuously. After one
month, H. scabra juveniles
were transferred into an
indoor nursery tank and
maintained until they
reached 1 g in weight
(~ 3 cm) and then they
were nursed in outdoor
