The paper deals with the feeding habits and sensonal variance of the feeding intensity of Hemibarbus maculatus in lake Nanhu, Wuchang. Specimens were taken from November 1984 to April 1987. It was found that Hemibarbus maculatus feed chiefly on non-spinal animal, such as chironomus, Oligochaeta, Gastropoda larva and Lamellibranchia larva, and that algae,protozoa,cladocerans and copepoda are secondary feed. Seasonal changes of the feeding intensity of Hemibarbus maculatus are not noticeadle difference, hence it is a kind of the good natured carnivorous fishes to eat all the year over.
