Archana Naganyal, Amita Saxena
The knowledge of the food of fishes, their feeding behaviour and physiology of digestion is of great importance for planning modern fishery programmes. In view of this fact in mind, food and feeding habits of different fishes of Kosi and Sharda Rivers had been studied. According to Polling (1993), feeding habits of fish help to find out the ecological condition of fish, niche in the ecosystem and preferred food items. In the present investigation, the feeding habits of different fishes were observed and it was concluded that some fishes were herbivorous (Glyptothorax pectinopterus, Garra gotyla, Schizothorax richardsonii), some fishes were carnivorous (Bagarius bagarius, Channa punctatus), some were omnivorous (Barilius barila, Botia almorhae, Puntius ticto, Xenentodon cancila, Tor putitora, Labeo dyocheilus) and Catla catla was found to be zooplanktivorous.
