The fishery and population dynamics of Otolithoides pama (Hamilton, 1822) were studied from the Hooghly-Matlah estuary of West Bengal from November 2016 to April 2018. The average annual catch of sciaenids for the last five years was estimated at 22 mt and formed 12.66% of the total marine production of the state of West Bengal, India. The peak landings of O. pama were found during March from gill net catches and November–December from bag net catches. The species followed continuous recruitment throughout the year with two distinct peaks during March–August and July–October. The probability of capture was estimated to be 148.35 mm, while the length at recruitment was 104.5 mm. The rate of exploitation (0.73) was found to be higher than Emax (0.58), indicating a higher fishing pressure of the species. The length-based Virtual Population Analysis revealed that the highest fishing mortality occurred from the 140–159 mm length group onwards. Both Beverton and Holt yield per recruit analysis and Thompson and Bell prediction analysis revealed higher fishing effort being employed for the species, which would need to be reduced by 20% for sustainable management of the species at the studied estuarine system.

印度西孟加拉邦 Hooghly-Matlah 河口的 Otolithoides pama (Hamilton, 1822) 的渔业和种群动态

2016 年 11 月至 2018 年 4 月，研究了西孟加拉邦 Hooghly-Matlah 河口的 Otolithoides pama (Hamilton, 1822) 的渔业和种群动态。过去五年的平均年捕捞量估计为 22 公吨，形成 12.66印度西孟加拉邦海洋总产量的百分比。3 月的刺网渔获量和 11 月至 12 月的袋网渔获量发现了 O. pama 的上岸高峰。该物种全年持续招募，在 3 月至 8 月和 7 月至 10 月有两个明显的高峰。捕获的概率估计为 148.35 毫米，而招募时的长度为 104.5 毫米。发现开发率（0.73）高于Emax（0.58），表明该物种的捕捞压力较高。基于长度的虚拟种群分析显示，最高的捕捞死亡率发生在 140-159 毫米长度组以上。Beverton 和 Holt 每次新兵的产量分析以及 Thompson 和 Bell 预测分析都显示，该物种的捕捞工作量较高，需要减少 20% 才能在所研究的河口系统中对该物种进行可持续管理。
