Abstract
The present investigation deals with the accounts of a novel species of ciliate parasite belonging to the genus Paratrichodina namely, Paratrichodina indiana n. sp. identified from the respiratory organ of goldfish Carassius auratus at Nadia district of West Bengal, India. 276 fish have been collected for parasitological examination from various fish farm of West Bengal, India. The parasitological investigation was conducted using the AgNO3 impregnation technique, which was supplemented by a taxonomic description, morphological variations and data comparison with previously documented closely related species. Paratrichodina indiana n. sp. is a small-sized trichodinid, measures uniquely 19.21 ± 1.6 µm in body diameter, with prominent adhesive disc measure 15.55 ± 1.22 µm. The current investigation supports the first record of the genus from C. auratus and adds one new species to the genus Paratrichodina, as well as report of a new host, region and prevalence rates.

Ethical approval
Fish were collected in fresh form from the different fish farms of West Bengal. At the point of time when work began on the parasites of ornamental fish, we approached Committee for the Purpose of Control and Supervision of Experiments on Animals (CPCEA), Ministry of Environment, Forest and Climate Change, and Government of India for ethical clearance. The committee informed that CPCEA instruction’s protocol for experimentation on fishes does not require CPCEA approval.
