Abstract
A survey of fresh water fishes Anabas testudineus (B1.) and Channa gachua (Ham.) of Utra Lake, Nambel. Bishnupur District, Manipur with reference to helminthic infection in relation to host length and sex was successfully accomplished. Fishes of different length groups of C. gachua and A. testudineus were examined regularly for parasitic infection between May 2008 — April 2009. Two species of nematode and one species of acanthocephala were collected. The parasite species showed significant variation in the prevalence and intensity of occurrence in different length groups of fish hosts. Such variations shown due to considerable changes in the diet of fish hosts and choice of food items are also factors of parasitic infection.
