During early southwest and northeast monsoon periods of 1967, zooplankton standing stocks and abundances were high all along the west coast of India. Swarms of zooplankton were common in the shelf areas resulting in a low diversity-high biomass community. Paradoxically, this happened when nutrient concentrations and phytoplankton biomass were low. The zooplankton `high` might have arose from an earlier nutrient enrichment through land run-off and increased phytoplankton or through the microbial loop. Distinct coastal and offshore communities among copepods were discernible. Their distributions did not show much change among seasons indicating an ability to maintain their positions in the preferred niches. Niche-partitioning among congeners was indicated
