Summary Length‐weight relationships ( LWR s) were determined for Dermogenys pusilla (n = 75) and Labeo bata (n = 304) from the Ganges River, northwestern Bangladesh, collected between July 2013 and June 2014, using traditional fishing gear (e.g. cast net, square lift net and gill net). Total length ( TL ) was measured to 0.1 cm and whole body weight ( BW ) was taken to the nearest 0.1 g for each individual. The TL varied from 6.60 to 16.10 cm for D. pusilla and 7.90–25.20 cm for L. bata . The BW ranged from 1.20 to 10.90 g for D. pusilla and 4.70–167.30 g for L. bata . All LWR s were highly significant (P < 0.001), with all r 2 values ≥0.976. Moreover, the present study provides a new record of the maximum length (16.10 cm TL ) for the D. pusilla female. The present study can assist in the management of these two endangered species in the Ganges River ecosystem.
