Hydrographic data collected from east coast of India during 1994 monsoon periodrevealed that these waters are highly characterized by upwelling especially in the coastalwaters with more intensity in the southern part of the region. However, the near surfacesalinity stratification consequent to high fresh water inflow into the bay was absent inthe present study. Oil sardines are directly influenced by hydrographic parameters suchas salinity and temperature and stratification of these parameters are the major reasonsfor non-availability/migration of oil sardine from this region in the earlier years.Considering the recent topographical change in the east coast coupled with hydrologicalstability an attempt has been made in this paper to give reasonable justification to thereported bumper catches of oil sardines from 1994 on wards in the east coast of India.
