Abstract : A survey of freshwater fishes, Channa striatus of Rohilkhand region with reference to Genarchopsis infestation in relation to host length and sex was successfully accomplished. Channa striatus (n=210) were grouped arbitrarily into three length groups (Group A: 7-10cm., Group B: 11-14cm. and Group C: 15-18cm.). The trematode parasite, Genarchopsis (Hemiuridae) was recovered from their intestine. The percentage of fish infestation was highest in Group A (20.83%) and lowest in Group C (3.03%). Concentration index was maximum, 3 par/host in Group B. It was observed that parasitic infection was higher (10.75%) in female fish hosts as compared to males (9.40%)
