To identify the food habits of three species of Mastacembelidae namely Mastacembelus armatus, Mastacembelus pancalus and Macrognathus aculeatus, the gut content analysis was performed by three methods i.e. occurrence method, points method and index of fullness method. All three species were found to consume prawn, molluscs, insects, earth warm, debris and plant materials. M. armatus and M. pan cal us were found to feed mainly on animal food items and 84.68% of different types of animal food were taken by M. armatus and 62.72% by M. pancalus. M. aculeatus was found to consume 44.86% of different types of animal food items, 53.51% of debris and plant materials which indicated that this fish feeds almost equally on animal and plant food. Analysis of the food habits showed that both M. armatus and M. pancalus are carnivore in nature with higher feeding preference for animal food namely prawn, crabs, fishes, molluscs etc. On the other hand, M. aculeatus is an omnivore in nature feeding almost equally on animal and plant food.
