AbstractAmong the important oceanographic parameters considered, the effect of
sea water tensperature and salinity on the Evaitebility of oil sardine and mackerel
appear to be very significant. The best catches of oil sardine were obtained when
surface-water temperature ranged from 27.7Â°C and 29.9''C and surfjce salinity
â€¢ ranged between 32.6 %. and .34.9 %.. No definite relat'oaship was found between
phytoplaaikton and oil sardine. High aibundance of mackerel was recorded when
the r:nge in surface-water temperature and surface salinity was from 28.4 to
29.9Â°C and 32.6 to 34.9 %. respectively. Correlation betw-sen zooplanktoa and
mackerel has not revealed any exact relationship between the two.
