Abstract

Studies on the growth of Meretrix casta (Chemintz) showed that the clams in the natural bed grew at the rate of 3.6-3.9 mm per month while the speciemens kept in the cages showed growth rates of 0.9 mm and 0.77 mm per month respectively for on bottom and off bottom culture. The equation for length weight relation was found .The spawning period of M. casta was found to be between April-May. Dispersal of clam seed in virgin areas did not yield fruitful results as there was heavy mortality due to floods.
