ABSTRACT
One hundred and twenty fishes (Labeo rohita) were examined for ectoparasites. Four species of the genus Lernaea recorded were L. polymorpha, L. cyprinacea, L. oryzophila and L. lophiara. The overall prevalence of ectoparasites was studied and observed that L. polymorpha had maximum overall prevalence (5.83%) followed by L. cyprinacea (5%), L. oryzophila (1.66%) and L. lophiara (1.66%). L. polymorpha and L. cyprinacea were the most abundant ectoparasites in mixed infestation and L. cyprinacea had highest parasite burden (4). Maximum intensity of infestation in L. rohita for L. cyprinacea (23), L. polymorpha (9), L. oryzophila (2) and L. lophiara (1) was recorded in 10-265g weight group, while minimum in 522-777g, 778-1033g, 1034-1289g and 1290-1540g weight groups. The infestation was not observed in minimum and maximum length ranges of host.
