Abstract

An atlas showing the correlation of oceanographic features with zooplankton biomass, fish eggs and larvae along the west coast of India during 1963-1969 from Cape Comorin to Bombay is presented with essential discussions on the inter-relationship between the hydrographic features and the biological aspects. The continental shelf region is found to be conspicuously richer in zooplankton biomass than the offshore regions. The peak of zooplankton biomass is observed during monsoon and postmonsoon periods. The low concentration occurring during summer and premonsoon periods are in good agreement with the similar work done elsewhere. During the summer months fish eggs and larvae show generally an increasing trend, but exceptions have also been observed when there was a higher abundance during the peak monsoon.
