Summary The present ichthyological report describes the length‐weight relationships ( LWR s) of three catfish species ( Eutropiichthys murius, Nangra nangra and Gagata viridescens ) belonging to two families from the Kaliganga River, a tributary of the Dhaleshwari River, Bangladesh. The analyses included 306 specimens collected monthly from fishermen's catches during October 2015 to April 2016. Ranges of regression parameters a and b of the three species were within 0.0058–0.0099 and 2.900–3.142, respectively with highly correlated coefficients of determination ( r 2 > .995; p < .001). The LWR s for all three species presented herein for the first time with a new maximum length record for N. nangra .
