Abstract

The commercially important bivalves along the Indian coast are clams, mussels, edible oysters and pearl oysters. Except pearl oysters, bivalves have been fished either for their meat or shell since time immemorial. Till 1961, pearl oysters were fished for the golden coloured pearls. When the pearl oyster beds became barren these activities became uneconomic and were not repeated. On the other hand, edible bivalves and ornamental shells became more popular and their fishery improved. During 1995-99, the average quantity of edible bivalve products exported per annum have been estimated as 580 tonnes, worth Rs.26 million and 567 t of oyster shell powder valued at Rs.1.5 million. The status of bivalve fishery ranges from under exploitation in the northwest and northeast coast to overexploitation in the southern maritime states.
