Trichodiniasis is a fish disease caused by ectoparasitic trichodinid ciliophorans and often causing a threat to the fishery sectors around the world. Infestation of fishes by this particular group of protozoan parasites is held responsible for low production caused by massive destruction of skin and gill epithelium of host fishes and further gets exposed to bacterial and viral diseases due to damaged tissue. Icthyoparasitological surveys in search of trichodinid ciliophorans were conducted in variouswild and cultured edible fishes in various ponds, lakes, rivers of the Purulia district of West Bengal during July, 2015 to June, 2018. Out of 593 host fishes of thirteen genera 142 fishes of eight genera were found to be infested by various species ofTripartiella. The study reveals that prevalence rates of the parasites vary with the seasons and hosts and interestingly it is evident that hybrid carps appear to be more susceptible than pure carps.
