Abstract
Lernaea spp., belonging to the family Lernaeidae were studied from Catla catla from February 1999 to January 2000 at Government Fish Hatchery Pirowal (Punjab, Pakistan). Four species of lernaeid found were Lernaea cyprinacea Linnaeus, L. polymorpha Ya, L. oryzophila Monod and L. lophiara Harding. Lernaea (yprinacea had maximum overall prevalence (26.67%) followed by L polymorpha (25.83%), L. oryzophila (4.17%) and L. lophiara (2.50%). The results of mixed infestation showed that L. cvprinacea was the most abundant parasite. Maximum infestation in C. catla for L. cyprinacea (36), L. polymorpha (34), L. oryzophila (3) and L. lophiara (1) was recorded in 214-413 g weight groups while minimum in highest weight groups. The infestation was lowest in minimum and maximum length ranges of host.
