Summary Length–weight relationships ( LWR s) for three fish species, Psiloryhnchus homaloptera Hora & Mukherji, 1935, Pseudecheneis sulcata (McClelland, 1842) and Devario aequipinnatus (McClelland, 1839), from the Kameng River in Arunachal Pradesh, India were estimated from August 2016 to October 2017. Fishes were collected seasonally using cast nets (2.5 m, 1.2 cm) and electrofishing device (Safari Surveyor, 12 V 7 amp). The b values in the LWR s were determined as 2.98, 2.93 and 2.72 for P. homaloptera , P. sulcata and D. aequipinnatus respectively. The coefficient of determination ( r ² > .95) for all the species is statistically significant.
