Description 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.
