- Abstract
Broodstock development, spawning and larval rearing of the false clown fish, Amphiprion ocellaris is studied under captive condition. A. ocellaris spawns in seawater and has also been bred in captivity using estuarine water. Continuous aeration and 10-20% water exchange was provided on alternate days. Temperature, salinity, pH, dissolved oxygen and ammonia were maintained at optimum levels. The fish were fed twice a day with various feed combinations like prawn/mussel/squid meat and live Acetes spp. At the age of six months in the hatchery, the fish attained 6.5-8 cm length and 14.6-15 g weight at the time of first spawning and laid eggs. The newly laid eggs were orange in colour, translucent and capsule shaped. The parents were allowed to remain in the spawning tank till hatching, which took place after 6-8 days and the hatching success rate was 90-95%. The newly hatched larvae measured 3-4 mm in length and were transferred into separate rearing tanks. They were fed with rotifers and Artemia nauplii and 21 days after hatching, the juveniles shifted from pelagic to epibenthic mode of life. The young ones were fed with different wet feed and they attained marketable size within three months. This is the first report on hatchery production of false clown fish, A. ocellaris both in India and elsewhere using estuarine water.
