ABSTRACT. The Meretrix casta is an edible clam for human beings and it is widely distributed around the aquatic ecosystem. The clam has relatively thick shells that can attain a length of three inches. The knowledge of the biology, culture and biochemical composition of any edible organism is extremely important. Though the size, shape and colour of clam are different their nutritive value is very good. A maximum average length of 27.15mm was observed in the M.casta studied during 2011 and a maximum average length of 26.51mm was observed during 2012. The average lengths of M.casta in all the three different estuaries studied were as follows: 27.15 > 25.82 > 25.04 mm in 2011 and 26.51 > 25.88 > 25.17mm in 2012. A maximum average weight of 7.824 and 7.155g was observed during 2011 and in 2012; a maximum weight of 7.528g and minimum of 6.941g was recorded uniformly in all the three different estuaries. However, in 2011and 2012 a maximum and minimum of average length of 26.86, 25.10 mm, and average weight of 7.67 and 7.05g respectively were noticed in both Vellar and Uppanar estuaries of M.casta. the present investigation, it is clearly observed that M.casta can grow a weight of 0.13g/day and length of 0.122mm/day among the three different estuaries studied in the Cuddalore district which is located in Bay of Bengal.

Seafood is an excellent provider of protein with high biological values. Fish, shellfish and other aquatic organisms are appropriate for food and have world-wide importance. They're wonderful sources of high quality proteins, superior to those in red meat and poultry foods. The human dietary amendments that characterize the "nutrition transition" include every quantitative and qualitative change in the human diets. The present study Meretrix casta meat is used for the preparation of excellent recipes like cake, soup and mint stuffed tomato with yellow clam using M. casta meat, that have the potential to be become a regular food item in the house hold diet with consumer acceptance. The differences in food habits over the length and breadth of the nation are most that available food resources are not being used properly due to the lack of information regarding their importance. The panel of judges vouched safe for taste and delicacy of the dishes in the present study. The panel detected that the dishes were a lot of as good as those created out of the much sought after seafood in taste, smell and flavor
