| Abstract: | The length‐weight relationships (LWRs) of three fish species; Toxotes chatareus (Hamilton, 1822), Datnioides polota (Hamilton, 1822), and Chela cachius (Hamilton, 1822) collected between September 2016 and August 2017 from Tentulia estuary of Bangladesh were analyzed. Fish were caught seasonally using set bag net and cast net with mesh size of 0.5 cm and < 0.5 cm, respectively. LWRs of Toxotes chatareus, Datnioides polota and Chela cachius were calculated as W = 0.0154L2.926 (r2 = .962), W = 0.0149L3.106 (r2 = .992) and W = 0.0109L2.968 (r2 = .981), respectively. The study provides a new maximum total length for Chela cachius. |
