Description Microzooplankton is an important component in the plankton food web transferring microbial food web carbon to the higher
trophic levels, including fishes. This study investigates the role and significance of microzooplankton in the diet of three
economically important small pelagic fishes along the southwest coast of India: Indian oil sardine (Sardinella longiceps),
Indian mackerel (Rastrelliger kanagurta) and Commerson’s anchovy (Stolephorous commersoni). The diet content of oil sardine
was dominated by diatoms throughout the year with an increase in the presence of microzooplankton and copepods during the
Northeast Monsoon. Phytoplankton, microzooplankton and copepods represented the diet of Indian mackerel throughout the
year. Commerson’s anchovy differed considerably in their diet composition from both Indian oil sardine and Indian mackerel as
they chiefly depended on a carnivorous diet feeding on copepods, fish eggs, ostracods, lucifers and microzooplankton. The
present study concludes that organic carbon from the microbial food web also, through microzooplankton, provides nutritional
support to small pelagic fishes along the southwest coast of India but in varying degrees depending on the fish species as well the
seasons.
