Abstract

Bivalves are notorious for their ability to bioconcentrate contaminants and hence they can be used as effective indicators for monitoring trace toxic contaminants in coastal waters due to their wide distribution, sessile life style, euryhaline nature, resistance to stress and high accumulation of wide range of chemicals and ease of sampling. Bivalve resources of Kerala State mainly include different species of clams, oysters and mussels. During 2005- 2006 period, the total bivalve landing was about 61280 tones, of which 75% was contributed by a single species, Villorita cyprinoides (black clam). More than 90% of the total black clam production of the state is supported by Vembanad Lake system.
