There are many factors which effects the production of fishes, parasites infection is one of the main reasons for increasing mortality of fish. The present study was performed to find out the effect of parasites on some economically important freshwater fishes with special reference to cestodes (tapeworms), as two more types of parasites were there other than cestodes which can badly affect the fish production such as trematode (flatworms) and nematode (roundworms). A total of 160 commercially important fishes belonging to eight families were taken for this study. 20 each from the following species Catla catla, Labeo rohita, Channa punctatus, Clarias batrachus, Cirrhinus mrigala, Heteropneustes fossilis, Mystus vittatus, Wallago attu were taken. Extreme infestations were observed in the fishes. The production of fishes were decreased due to the infestation of cestode parasites. Very few work has been done in this topic till date, especially studies on cestode parasites. It is an attempt to find out those parasites which are particularly affecting these commercially important fishes.
