Virtual population analysis using the Jones’ length-based cohort method was conducted to the Glory scallop (Mimachlamys gloriosa Reeve, 1853) from Asid Gulf, Philippines. The study aimed to reconstruct the biomass and population structure as inputs to estimating the maximum sustainable yield (MSY) along with the fishing mortality expended on the stock and evaluate the effect of introducing minimum size restriction to the yield and biomass of M. gloriosa. Length-frequency data sampled from commercial catches covering 12 months from April 2018 to March 2019 were used and analyzed. The proportion of M. gloriosa from the total scallop production was transformed into total catches (in numbers) using the allometric length–weight relationship W = 0.5632L^2.295 (R² = 0.90). The estimated population of M. gloriosa is about 300,000 individuals, equivalent to a mean biomass of 6.76 tonnes (T). The estimated total yield of 8.09 T is relatively higher than the estimated maximum sustainable yield (MSY = 5.88 T), indicating unsustainable harvesting and high fishing pressure. This excessive harvest coupled with high exploitation ratios (E yr⁻¹) ranging from 0.65 to 0.84 directed toward the larger length-groups (5.65–8.45 cm, SH) would imperil the breeding stock and lead it to recruitment overfishing. Using Thompson and Bell model, the effect of imposing minimum size (6.35 cm shell height) restriction shows an increase of 7.62% and 20.45% to the annual yield and biomass, respectively which is a positive implication of this strategy.

对来自菲律宾 Asid 海湾的 Glory 扇贝 ( Mimachlamys gloriosa Reeve, 1853)使用琼斯基于长度的队列方法进行了虚拟种群分析。该研究旨在重建生物量和种群结构，作为估算最大可持续产量 (MSY) 以及种群的捕捞死亡率的输入，并评估引入最小尺寸限制对M. gloriosa产量和生物量的影响。使用和分析了从 2018 年 4 月至 2019 年 3 月的 12 个月商业渔获量采样的长度频率数据。使用异速生长长-重关系W将M. gloriosa占扇贝总产量的比例转换为总产量（数量） =  0.5632L ^2.295（R ²  = 0.90）。M. gloriosa的估计种群数量约为 300,000 只，相当于平均生物量 6.76 吨 (T)。8.09 T 的估计总产量相对高于估计的最大可持续产量（MSY = 5.88 T），表明不可持续的捕捞和高捕捞压力。这种过度的收获加上高开采率（E yr ^-1) 范围从 0.65 到 0.84，针对较大的长度组（5.65-8.45 厘米，SH）会危及种畜并导致其招募过度捕捞。使用 Thompson 和 Bell 模型，施加最小尺寸（6.35 厘米壳高）限制的效果显示年产量和生物量分别增加了 7.62% 和 20.45%，这是该策略的积极含义。
