A multi-model analysis of growth and maturity biometrics in common Snakeheads, Channa striata, and Channa punctatus collected from Hakaluki Haor, Northeast Bangladesh

The Snakeheads are the most common fishes in freshwater wetlands of Bangladesh, but recent years they subjected to decline by overfishing pressure, anthropogenic factors, and climate changes. A one-year-long biometric investigation was undertaken which involve monthly random sampling Channa striata punctatus from local wetland waters measured total length, body weight data, gonad’s laboratory. Then data were treated analyzed following different multi-model tools i.e., Fulton’s condition factor, relative allometric Pearson’s correlation coefficient. results exhibit a strong between length with an r2 value 0.826, 0.819, respectively. showed trend both positive negative coefficients conditions factors morphometry for species. peak weight, gonadosomatic index, Dobriyal index reported monsoon while bottom winter sexes temperature, dissolved O2, turbidity found as fluctuating throughout season NH3 pH remained constant. This will help betterment conservation, management, fishing policy government, scientists, fisheries industry.
