Abstract

Tropical marine aquarium fishes have demand in the international market. Clownflshes or anemonefishes are most popular among marine aquarists due to their attractive colours and interesting display of behaviour with sea anemones. A technology for the hatchery production of the clownfish, Amphiprion chrysogaster was developed for the first time in India. The broodstock maintained in the hatchery spawned frequently and methods were developedfor hatching the eggs. The hatching period was 6-7 days. A simple biological detoxifying filtration system with effective circulation was designed and fabricated for larval rearing. The larvae were fed with the rotifer Brachionus rotundiformis at a concentration of 6-8 numbers per ml for the first four days. From the fifth day onwards they were fed with a mixture of B.rotundiformis and freshly hatched Artemia nauplii. The larvae metamorphosed into Juveniles in 12 to 15 days from, the day of hatching. Thejuveniles were kept in the rearing tank for one week to one month by feeding them with Moina mlcrura and then transferred to grow out tanks with sea anemones. By upscaling the present technology, large scale hatchery production of clownfish young ones could be achieved.
