Abstract
It is generally recognised that fluctuatiops in the environmental parameters in the seas have a significant influence on the life history, abundance and migratory habits of fishes. It is well known that along the south west coast of India seasonal ab~ndance and migration towards coastal area by pelagic species such as oil sardine and mackerel are governed by several meteorological and oceanographic parameters such as seawater temperature, salinity, pH, upwelling, nutrient concentration and plankton production which are in turn influenced by wind, rainfall and coastal currents
