Abstract: The information on the feeding habits of fish helps to know about the inter-specific relationship of aquatic fauna and the productivity of the water body. In the present study, the feeding habit and preferred food contents of Cirrhinus mrigala from Ukai reservoir of Gujarat was discussed with reference to index of preponderance. The quantitative composition of food components was analysed during June, 2013 to May, 2014 and found that the gut was consisted by decay matter, phytoplankton, plant material, zooplankton and insects. The results showed that decay matter and plankton dominated in gut contents and considered as main food component during breeding, post breeding, pre-breeding seasons and pooled data. Hence, it can be concluded that C. mrigala was omnivorous in feeding habit and findings were also verified by the index of preponderance.
