Abstract

A full fledged pearl oyster hatchery was established at R.C. of CMFRI, Mandapam Camp along with a temperature controlled micro algal culture laboratory. The hatchery house four 5 ton capacity circular FRP tanks for storage of filtered sea water and 28 nos of 1.5 ton rectangular FRP tanks for larval rearing. A central drain of 80 m length connects the hatchery to the sea. Sea water supply is effected through 7.5 and 10 HP pumps connected to sedimentation tanks, ground level sumps and to overhead tank. Two sand filters were erected for effective filtering of sea water. Aeration is provided with air blowers and air compressors. The annual production capacity is estimated to be 2.8 million spats. Induced spawning and larval rearing gave encouraging results and 0.7 million spats were produced during June-August 1997.
