Evaluating biometric indices for Indian Gagata, Gagata cenia (Hamilton, 1822) through multi-model inferences

First report on population dynamics and stock status of Badis badis in a wetland ecosystem (NW Bangladesh): Insights from new recorded maximum length

“…The slope parameter ( b ) in LWR is employed to determine the pattern of fish growth [ 38 , 58 ] and the condition factor (CF) is crucial for gaining information on ecological adaptation of fish [ 58 , [63] , [64] , [65] ]. In fisheries, LWRs prove extremely valuable for converting length distributions into weight measurements, facilitating biomass assessment [ 66 , 67 ]. The size categories of fish can impact on the distribution of individuals within a population of fish [ 66 , 68 ].…”

The size categories of fish can impact on the distribution of individuals within a population of fish [ 66 , 68 ]. To construct ecosystem models, it is essential to have information on growth parameters like the von Bertalanffy growth coefficient ( K ), asymptotic length ( L ∞ ), age at zero length ( t 0 ), maximum reported age ( t max ), size at sexual maturity ( L m ) and natural mortality ( M w ) [ 66 , 69 ].…”

Moreover, L m is a critical management metric used to determine whether a collected stock contains a sufficient number of juveniles that are mature and ready for reproduction [ 66 , 71 ].…”

Moreover, L m is a critical management metric used to determine whether a collected stock contains a sufficient number of juveniles that are mature and ready for reproduction [ 66 , 71 ]. Furthermore, morphometric relationships such as LWR, K R , and K F are crucial biological measurements for fish, which can be used to evaluate the condition of fish stocks and the well-being of fish populations [ 66 , 72 ].…”
