Steps taken for broodstock development of Neopomacentrus nemurus, Coral demoiselle
(Bleeker, 1857) in a hatchery, its spawning and development of egg to the juvenile
stage are described. Among the three treatments tried, only the trial using
Parvocalanus crassirostris nauplii as the first diet helped in the development of larvae.
Larval and post‐larval growth was studied for a period of 65 days post hatch. The
larva measured 2–2.4 mm in total length at the time of hatching. The mouth size of
larva at the time of hatching measured 237.92 μm. By the 5th day, the width of the
larval body had significantly increased. All the fins were conjoined, except for the
caudal fin which had begun its appearance on the 2nd day itself. The digestive system
was functional by the 5th day and the copepod remains were seen in the digestive
tract. The larva metamorphosed by the 15th day with fully developed fins and
fin rays. On the 20th day, the larval body had begun to display signs of fin pigmentation.
The larva assumed adult pigmentation by the 35th day. By the 65th day, the
larva grew to a total length of about 27 mm and weighed about 0.56 g.
