Abstract

The bagrid catfish Chandramara chandramara (Hamilton) was originally described from North Bengal province, India and has now been recorded from Arunachal Pradesh, for the first time. The specimens were collected by the authors using cast net from the Singen river of East Siang District, Arunachal Pradesh. The specimens were preserved in 10 % formalin and deposited in Rajiv Gandhi University Museum of Fishery (RGUMF), Rajiv Gandhi University, Itanagar, Arunachal Pradesh, India. The detailed description, diagnostic, and comparison of the specimens agreed with the original description of Chandramara chandramara (Hamilton) and thereby it extends the geographical distribution of the species chandramara chandramara (Hamilton) up to the water bodies of Arunachal Pradesh, exhibiting its wide range of habitat adaptability.
