Description The clam Meretrix meretrix, the green mussel Perna viridis and the oyster Crassostrea madrasensis
exist in the Ennore Estuary. The ' bar' is open throughout the year and as a result except during
the Northeast Monsoon period when there is significant fall in salinity, higher salinity as in the inshore
waters are prevalent. The present investigations were designed and aimed at studying the salinity
tolerance of the above mentioned bivalves. In the experiments conducted they were subjected to a
series of salinity changes ranging from 0 to 35 %„. The rates of mortality of the animals in different
salinity media were noted at the end of 24 hours for a consecutive period of ten days. It was found
that the bivalves were tolerant to the salinity change of the experimental media when the survival
rate was 50% and above at the close of this period. The results obtained show that Crassostrea
madrasensis, Meretrix meretrix and Perm viridis can tolerate an approximate low salinity of 7,
13 and 16%, respectively under laboratory conditions.
