Venerid clam, Paphia malabarica Chemnitz, is the commercially exploited species distributed exclusively in Vembanad Lake and
Ashtamudi estuary, along the south west coast of India. In this study, the survival rate and
development of P. malabarica larvae were studied for 3 days in ambient salinity (33), copper (2.5 μg
Cu2+ l−1), reduced salinities (25 and 20) and a combination of copper in low salinities. No significant
differences were found in larval development between treatments. The survival rates decreased
considerably with low salinities although the combination of copper and low salinity gave
synergistic effects. The reduced survival in low salinities would limit population growth of this
species in estuarine areas experiencing low salinities and also explains the absence of larval
settlement on habitats close to harbors or river mouths.
