Clams are bivalve molluscs, which burrows into the substratum with the help of a
well-developed foot. Among the exploited bivalve resources of India, clams are by
far the most widely distributed and abundant. The clams form subsistence fisheries
all along the Indian coast. Clam fishing plays an important role in the economy
of the coastal fishing villages. Clam meat is nutritious and is a cheap source of
protein rich seafood. Clam culture is practiced in several countries and in India
it is yet to take off on commercial lines. There is growing interest in several
tropical countries to develop clam culture on scientific lines.
