Stock assessment of barred spiny eel, <i>Macrognathus pancalus</i> (Hamilton, 1822) in a wetland ecosystem, northwestern Bangladesh: A fundamental approach to ensure sustainability and conservation.

ABSTRACT: This research delved into the management approach for Macrognathus pancalus within the Gajner Beel of northwestern Bangladesh, employing a comprehensive array of length-based indicators. The study encompassed an investigation into population structure, growth parameters (including asymptotic length (L _∞ ), asymptotic weight (W _∞ ), growth coefficient (K), and age at zero length (t ₀ )), mortality parameters, growth performance indices, recruitment pattern, exploitation rate (E), relative yield per-recruit (Y'/R), optimum catchable length (L _opt ), longevity, biomass, and maximum sustainable yield (MSY). The TL and BW ranged from 5.00 to 16.20 cm and
