Abstract

Broodstock development, breeding, spawning, larval rearing and growth of black Amphiprion ocellaris in captivity are
described in this study. The black ocellaris, a magnificent colour morph of A. ocellaris was bred in captivity at Vizhinjam
Research Centre of ICAR-Central Marine Fisheries Research Institute (ICAR-CMFRI). Two adults, approximately 4-6 cm
in total length (TL) were stocked in FRP tanks of 300 l capacity, under optimum water quality. The broodfishes were fed a
combination of boiled mussel meat, boiled squid and semimoist feed (protein - 40 %, lipid - 9.5 %, fibre - 2% and moisture
- 31%) twice daily at a rate of 3-5% of their body weight. After a period of 1.7 years, the fishes started showing courtship
behaviour and initiated spawning. The oocytes were of 3-3.3 mm in length and 1.1-1.9 mm in width. Approximately
200-300 eggs spawned the first time and the number of eggs gradually increased in subsequent spawnings. Spawning was
obtained at an interval of 12-14 days providing an average of two spawnings per month. The incubation period of the eggs
were 7-8 days and the fertilised eggs hatched on the 8th day, soon after sunset, generally between 19.00 and 20.00 hrs.
Different strains of cultured plankton like Isochrysis galbana, Nanochloropsis oculata, L-type rotifer Brachionus plicatilis,
calanoid copepod Acartia southwelli and Artemia were used as feed for larvae. The newly hatched larvae with a total length
of 5±0.16 mm metamorphosed to juveniles on the 40th day (18.87±0.07 mm). Black ocellaris is a highly priced clownfish
and can be used to crossbreed with the normal orange coloured ocellaris clown fish to produce different colour variants.
