Abstract Length–weight relationships (LWRs) and length–length relationships (LLRs) of three ecologically important fishes ( Aplocheilus panchax , Danio rerio and Esomus danrica ) were reported from a wetland, northeastern Bangladesh (23 58 N, 89 38 E). Samples were collected monthly using traditional fishing gear including fine meshed (2.0 mm) push net and fine meshed (3.0–4.0 mm) surrounding net during January to December 2014. For each individual, total length (TL), fork length (FL) and standard length (SL) was measured to 0.1 cm, while body weight (BW) was measured to 0.01 g accuracy. Allometric coefficient ( b ) values were 3.10 for A. panchax , 3.38 for D. rerio and 3.52 for E. danrica . In addition, the LLRs were also highly significant with r 2 ≥ 0.954.
