dc.description.abstractThis research work affirms the morphometric characters and meristic counts of Channa punctata (Bloch, 1793) in a wetland ecosystem (Gajner Beel) from the northwestern Bangladesh. A sum of 307 specimens of C. punctata were sampled intermittently from the Gajner Beel during July 2017 to December 2018, using different established fishing gears (cast net, gill net and square lift net with mesh size ranges: 1.50-2.50 cm, 1.50-2.00 cm, & ~2.00 cm, respectively). Fin rays were counted by a magnifying glass. Seven diverse morphometric lengths were assessed and BW (body weight) was weighted for each specimen. The fin formula was: dorsal, D. 30-32; pectoral, P1. 15-17; pelvic, P2.5; anal, A. 19-21; and caudal, C. (ii -iv/12-14). Minimum and maximum sizes were 5.80 and 23.00 cm in total length (TL), whereas BWs were1.96 and 126.90 g, respectively. All length-weight relationships (LWRs) were greatly significant (p < 0.001) with r2 ≥ 0.986. Based on r2 value, BW = 0.0112*(TL)2.98 was the most appropriate model among seven equations. Besides, based on r2 values, length-length relationships (LLRs) by TL vs. SL was the finest model among six equations. These findings will help for species identification and further stock/ biomass estimation of C. punctata in the Gajner Beel or connected ecosystems.en_US
