Feeding intensity and food spectrum of Labeo rohiia (Hamilton) were monitored along with water characteristics in Kulia bee! of West Bengal during premonsoon and postmonsoon seasons. Gastrosomatic Index and percentage of actively fed fish were significantly more during postmonsoon period. Diet composition during two sea.sons exhibited distinct variations. Such seasonal dynamics in feeding intensity and foraging was attributed to abundance of plankton and spawning of fish.
