Extension of distributional range with a new record of cyprinid Opsarius dogarsinghi (Hora, 1921) from river Torsa of Jaldapara National Park complex, West Bengal, India

Abstract

A cyprinid, Opsarius dogarsinghi (Hora, 1921) was recorded for the first time in September 2021 from the Kodalbasti section of the river Torsa, Jaldapara National Park complex. In September 2021, gill nets with a mesh size of 30 mm were used to catch a total of three specimens of O. dogarsinghi from the flowing water in the Kodalbasti section of the river Torsa. The species is endemic and has only been reported from a few north‐eastern regions of India. The current research widens the species' geographical range from its original habitat in the river Torsa of West Bengal, India. The physicochemical properties of their riverine habitat were also described.
