The fauna of cestodes are found both in marine and fresh water fishes of different part of our country. The species Puntius is one of the important freshwater fish with high nutritional value and market demand because of its relatively little bit lesser cost and abundance in the fish market. But due to parasitic infection it poses threat to fish cultivation, which is a valuable source of nutritional food and employment. In the present study the survey of IMC and quantification & incidence of the cestode parasite of fresh water fish in Puntius conchonius has become of high concern. These fishes were collected from local fish market Dumraon, Dist. Buxar, Bihar, during the month of January to February 2018. Out of 105 fishes specimens of P conchonius 10 were highly infected with adult cestode parasites. The encountered parasitic species includes Senga spp. & Circumoncobothrium spp.
