Description Seasonal fluctuations in the food of the oilsardine Sardinella longiceps landed by ring seines from the inshore waters off
Cochin were studied during 2010. S. longiceps is chiefly a plankton feeder with diatoms, dinoflagellates and zooplankton
appearing in the diet in decreasing order of abundance. During pre-monsoon (February-May), Pleurosigma was present in
70% of the stomachs analysed followed by Thalassiosira, Biddulphia and Coscinodiscus. During monsoon season
(June-September), 87.5% of the stomachs contained Coscinodiscus followed by Thalassiosira and Pyrophacus. During
post-monsoon (October- January) again, the frequency of occurrence of Pleurosigma (74.2%) was higher followed by
Biddulphia and Thalassiosira. Zooplankton, represented by tintinnids and copepods, were present in the diet throughout the
year, but in relatively less number of stomachs. Higher feeding activity was observed during monsoon (June-September),
which coincided with maximum spawning activity.
