Abstract

Indian pearl oyster belonging to the Genus Pinctada occurs in the two Gulf zones of India ie., Gulf of Kutch in Gujarat and Gulf of Mannar in Tamil Nadu. Commercial fishery existed in GoM till 1961 and then has gone into a dormant period due to many reasons including insignificant natural settlement of spat in the pearl beds (‘paars’) of Gulf of Mannar. To sustain a pearl culture industry, a steady supply of pearl oyster seed and farming it to mother oysters is a pre requisite. Large scale collection of pearl oyster spats either by using spat collectors or from their natural beds was not always found dependable owing to the irregular spat fall. Hence, hatchery production of pearl oyster seed and mother oyster culture has become an essential aspect as far as pearl culture is concerned. The following account details the basic hatchery requirement, broodstock maintenance and spawning and hatchery production of spats of Pinctada fucata and the methods of farming the spats for mother oyster development.
