Labeo calbasu (Ham.) was found to be a bottom dwelling illophagic fish. The food of the fish consisted of decayed organic matter, molluscs, diatoms, plant matter, green-algae, blue-green algae and zooplankton. The fish was selective in feeding. Juveniles showed a positive selection for zooplanktonic organisms. The adult showed a negative selection for the zooplankton and a positive selection for decayed organic matter and molluscs. The increased feeding intensity of the fish corresponded to a period of maximum available food in the habitat. Maturation of gonads also influenced the feeding intensity of the fish. Post spawning feeding intensity was found to be maximum.
