Abstract

Trichodiniasis of fishes cause harm and economic losses in the fish industry. There are many records of trichodinids ectoparasites infesting fish throughout the World, but no such attempt has been made to study the parasitic group infesting goldfish, Carassius auratus in India. During survey, an attempt have been made to survey trichodinid ciliophorans of some ornamental fish occurring in different parts of West Bengal, India and revealed the occurrence of two new species belonging to the genus Trichodinella on the basis of silver nitrate impregnation technique followed by taxonomic description, morphometric variability and comparative data in respect to closely related species. Trichodinella rectangulata n. sp., Trichodinella bengalensis n. sp. The species has been uniquely characterized by the acute, straight rectangular blade and elongated ray structure respectively. The present study confirms the first report of this genus from C. auratus and added two more species to the genus along with new host, locality records and prevalence rates.
