Sreenivasan, P V (1982) Growth of the clam Meretrix casta (Chemnitz) transplanted in the Vellar estuary. In: Proceedings of the Symposium on Coastal Aquaculture part 2, MBAI, 12-18 January 1980, Cochin.
The backwater clam Meretrix casta on transplantation in the Vellar estuary, was observed to grow from 7.5 mm in length in September 1976 to 41.5 mm by October 1977 attaining 34 mm in 13 months. Corresponding increase in breadth, depth and weight was 29.9 mm, 24.8 mm and 31.07 gm respectively. Growth was retarded in October-December when low salinity prevailed in the estuary. Growth was fast In January- March when salinity and temperature began to rise. Growth was moderate to low from April to September which was the spawning period for the species in Vellar estuary. Growth of the transplanted individuals was much faster than those in the natural bed. Dimensional relationships of breadth, depth and weight on length of the cultured clams were so estimated.
