Abstract

The black lip pearl oyster, Pinctada margaritifera (Linnaeus,1758) is a marine oyster distributed in the South Pacific, Indo-Pacific regions and the Red Sea. Globally, it is one of the three valuable pearl producing oysters in the pearl culture industry, apart from Pinctada fucata and Pinctada maxima. However, in India, the distribution of P. margaritifera is limited to Andamans and Nicobar Islands and occurring very rarely in Gulf of Mannar. (Alagarswami, 1983). Spat of Pinctada margaritifera was collected from the intertidal rocks off the coast of Visakhapatnam 17.7° N–83.3° E, Andhra Pradesh (Bay of Bengal) during low tides. The spat was light green in colour with alternate white and green radial pattern with distinct growth processes. They were acclimatized and reared in 1 t fiberglass tanks in the marine hatchery.
