Description 103-106
Food and feeding habits of J. axillaris (9 to 20.6 cm standard length) were studied from May 1977 to April 1978 using the points, volumetric and frequency of occurrence methods. Crustaceans, mainly composed of prawns, formed the bulk of the stomach contents followed by Squilla, teleosts, polychaetes and crabs in the order of abundance. There was no marked seasonal variation in the average amount of feeding and feeding index. However, the feeding intensity was high during May, June, August and September. The index of preponderance was calculated to grade the food items preferred. Comparison of all the results showed that in a carnivore like J. axillaris the 3 methods are equally useful.
