- W40145528 abstract "Of the 6 distinct species of Pinctada Roding (Pteridae) viz., Pinctada fucata (Gould), P. margaritifera(Linn.), P. chemnitzi (Philippi), P. anomioides (Reeve,) P. sugiUata (Reeve) and P. atropurpurea (Dunker),the first named species is the common pearl oyster of India, occurring on the pearl banks off Tuticorin coastin the Gulf of Mannar on the rocky ridges extending all along the coast of the gulf at depths of 15 m-25 m.They are occasionally found in the Palk Bay also in shallower waters lying in loose clusters over a bottomof coarse sand grains covered with a matrix of dead shells. In the Gulf of Kutch they are found on theintertidal reefs.The pearl fishery in the Gulf of Mannar is unpredictable and it is a question of utilizing the natural resourceas and when the pearl oyster spat settle down and grow. It is difficult to have effective control over the conditionsaffecting the settlement and growth of the pearl oyster in the natural beds because of their occurrencein the open sea.For the purpose of conducting an organized fishery, the population of fishable oysters should bedetermined with accuracy. The existing method of estimation of population, the knowledge of the groundsand the method of fishing require reorientation. To this end a thorough survey of the areas of oyster settlementwas undertaken for a period of 3 years and the grounds charted for the first time by means of directunder-water observations by SCUBA. The outlook for pearl fisheries in the next few years is rather bleakat present.The success and failure of the pearl fisheries of the past and the futile attempts made over a numberof years to watch for the possible settlemenet of the pearl oyster spat show that the only alternative to putIndia in the map of pearl producing nations is to resort to pearl culture practices." @default.
