| Abstract: | The present study describes the length‐weight relationships (LWRs) for nine fish species from the Tetulia River, southern Bangladesh, namely Anabas testudineus, Coilia dussumieri, Otolithoides biauritus, Otolithoides pama, Pethia conchonius, Polynemus paradiseus, Puntius lateristriga, Setipinna taty and Sillaginopsis panijus. A total of 1380 specimens were caught using traditional fishing gear from March 2012 to February 2013. Individual total length (TL) and body weight (BW) were measured by digital slide calipers and digital balance, respectively. The LWR was calculated as W= a Lb, where the W is the BW in g and L the TL in cm, a and b are regression parameters. This study presents the very first references on LWRs for seven of the species. The results are valuable for the application of sustainable management and conservation of these fishes in the Tetulia River and surrounding ecosystems. |
