“…This study's findings, however, show that juvenile and immature fish made up the bulk of the catch (P mat = 17% and P opt = 20.65%), and the number of mega-spawners was low; this is evidence that the stock is being overfished in terms of both recruitment and growth. According to the results of a gonado-somatic index (GSI) investigation [66], males reach maturity at 26.5 cm in length, whereas females reach maturity at 28 cm. However, 50% maturity length (L m ) was calculated to be 30.63 cm based on the results from this study's catch composition analysis.…”

The black pomfret (Parastromateus niger) is one of the high-income-generating carangid fish species and the only known member of its genus. This study aims to identify existing gaps in stock status and population demography of this species and provide viable management recommendations to enhance the sustainability of this fishery. Therefore, three methodological approaches have been used in this study; TropFishR to present the current exploitation status, the length-based spawning potential ratio (LB-SPR) to quantify stock spawning biomass, and Froese’s sustainability indicators (LBI) to establish a basic standard for sustainable management of the fishery. In the length-weight relationship of black pomfret, an allometric growth pattern (b = 2.19) was found. The VBGF life history parameters for black pomfret were L∞= 55.25 cm, K = 0.54 year−1, and based on LCCC analysis, the total mortality (Z = 1.61 year−1), natural mortality (M = 0.69 year−1) and fishing mortality (F = 0.91 year−1) are calculated. The result reveals that this fishery is currently suffering from overexploitation and the stock’s spawning biomass (SPR = 13%) is below the limit reference point because most of the catch (82%) was found to be under the maturity level. Based on the results, this study recommended strictly maintaining the mesh size of the net to ensure not to catch immature fish with a length smaller than 30.63 cm, recommended the length to catch be between 29 and 35 cm, and reducing fishing pressure by one-third to ensure the sustainability of the black pomfret fishery.

“…Parastromateus niger, is one of the important fish species from the economic point of view (Salim et al 2020;Islam et al 2021), with systematic position of this species as among the perciform (Bloch, 1795). These fishes are exported to various countries of world like China, Sri Lanka, Thailand, Malaysia and Japan, which is an important factor to boost the economic growth of Gwadar.…”

Background: Parastromateus niger, is one of the important fish species from economic point of view in Gwadar, Balochistan-Pakistan. This study was carried out to determine the growth and fecundity of Parastromateus niger. Methods: Growth of P. niger was determined by applying Le Cren formula while mean fecundity and relative fecundity of this fish was calculated by using equation of Yelden and Avsar. Result: Relationship between fish weight and ovary weight was found as 0.384 and 0.898 respectively in 1st and 2nd year of research. Annual mean fecundity of P. niger was calculated as 43165.4 eggs with relative fecundity of 73.7 in 2017-18 and annual mean fecundity in 2018-19 was 39759.5 eggs with 50.2 relative fecundity. Value of R2 in first year of research between fecundity and ovary weight was 0.751, for mean fecundity and relative fecundity was 0.545, in term of fecundity and total length of fish was 0.60 and for fish total weight and fecundity was 0.596. Value of R2 between fecundity and weight of ovary was 0.951, with mean fecundity and relative fecundity as 0.968, between fish fecundity and total length was 0.578 and in case of fecundity and total body weight was found 0.809 in second year of research period.
