Exploitation of clam Meretrix casta in Gadilam estuary

During the last two decades, clams were exploited in large quantities from estuaries and backwaters to feed shrimps cultured in the commercial ponds along the east coast of India. In recent years, clam meat is served as a dish in hotels in places like Bangalore, Kanyakumari, Chennai and Kerala. Heavy exploitation of the clam Meretrix casta along the bar-mouth of Gadilam estuary was observed during March and April 2006. About 80 to 100 men and women belonging to Kodikkalkuppam, Suthukulam and Devanampattinam were regularly employed in handpicking of clams for two months
