Present study was conducted to investigate the occurrence and pathological changes induced by Gangesia sp. in the intestine of freshwater fishes, Wallago attu. The study was conducted during July 2010 to December 2011. A total of twenty four (24) samples of fish, wallago attu were collected from Sukhana Dam. Sixteen (16) species of tapeworms were collected from the intestine of host fish. The incidence of infection, intensity of infection, index of infection, abundance and dominance of parasite has been recorded. The parasites have caused severe changes in the host. The infestation of helminth parasites to the fish brings vital changes in the host body.
These changes not only reflect on the physiological status of the organism but many important physiological functions are interrupted. The energy yielding process of the body is generally effected thus the physicochemical constituents of various regions of the host effected. Worms penetrate through intestinal layers causing damage to mucosa, submucosa, and come to lie near the muscularis mucosa.
