Abstract

The Gulf of Mannar and the Palk Bay zones of the southeast coast of India, the Halar coast of the Gulf of Kutch especially the reefs of Sachanai Salaya, Piroton, Ajad etc. and a narrow strip in the extreme southwest coast of India from Colachel to Trivandrum arc all places where either the chanks or the pearl oysters or both occur in fairly large numbers. In addition to the above, chanks occur along the Coromaadal coast upto Madras although this stretch is of minor importance. In some places in Andamans also chanks occur in limited quantities. Of all the places the most productive areas, as far as the pearl oysters are concerned, are located in the Gulf of Mannar and very rich chank beds exist both in the Gulf of Mannar and in the Palk Bay. Naturally much attention has been focussed on these two regions to study the fisheries and ecology of these two commercially important molluscs as evidenced by the works of Hornell (1914, 1916, 1922a), and Mahadevan and Nagappan Nayar (1966,1967, 1968). Very little is known about the other areas except for Hornell's report (1909) on the marine biology of the Okhamandal coast of Kathiawar.
