The catch-maximum sustainable yield (CMSY) method and a closely related Bayesian state-space Schaefer surplus production model (BSM) were combined with published catch data and catch per unit effort (CPUE) time series or spawning stock biomass (SSB) data to evaluate fisheries reference points for exploited resources of the Japan Sea. Eleven fish and invertebrate stocks were assessed; outcomes obtained through this analysis were the carrying capacity, biomass trajectory, maximum sustainable yield, and related parameters of each stock. Results showed that the stock of Arctoscopus japonicus was slightly overfished; the stocks of Cleisthenes pinetorum, Hippoglossoides dubius, Paralichthys olivaceus, and Chionoecetes opilio were overfished; and the stocks of Eopsetta grigorjewi, Pagrus major, Gadus chalcogrammus, and Glossanodon semifasciatus were grossly overfished; Pseudopleuronectes herzensteini was proved to be severely depleted; only Pandalus eous was in good condition. These results are consistent with the few previous studies on the status of fish species around the Japan Sea, where overfishing is becoming increasingly apparent. These assessments provide a basis for guiding the use, management, and rebuilding of fishery resources in the Japan Sea.

使用 CMSY 和 BSM 方法评估日本海 11 种被开发的鱼类和无脊椎动物种群

捕捞最大可持续产量 (CMSY) 方法和密切相关的贝叶斯状态空间 Schaefer 剩余生产模型 (BSM) 与已发布的捕捞数据和单位努力捕捞量 (CPUE) 时间序列或产卵种群生物量 (SSB) 数据相结合，评估日本海开发资源的渔业参考点。评估了 11 种鱼类和无脊椎动物种群；通过该分析获得的结果是每个种群的承载能力、生物量轨迹、最大可持续产量和相关参数。结果显示，北蚬种群略有过度捕捞；Cleisthenes pinetorum、Hippoglossoides dubius、Paralichthys olivaceus 和 Chionoecetes opilio 的种群被过度捕捞；以及 Eopsetta grigorjewi、Pagrus major、Gadus chalcogrammus 的种群，和 Glossanodon semifasciatus 被严重过度捕捞；Pseudopleuronectes herzensteini 被证明严重枯竭；只有潘达卢斯状况良好。这些结果与之前关于日本海周围鱼类物种状况的少数研究一致，那里的过度捕捞变得越来越明显。这些评估为指导日本海渔业资源的利用、管理和重建提供了基础。
