The China government has introduced many strategies in fisheries management of the Yellow Sea and the Bohai Sea, the most stringent of which is the summer fishing moratorium. Whether the summer fishing moratorium can restore fishery resources has always been a concern. In this study, we selected eight representative commercial fish species the Yellow Sea and Bohai Sea, including , , , , , , and , and used the JABBA method to study their historical exploited dynamics and current stock status. We evaluated the effectiveness of the summer fishing moratorium based on the increments of biomass and catch after its implementation and adjustments. . and . stocks were in the healthy status in 2022, the other six fisheries stocks were overexploited. The summer fishing moratorium had a strong conservation effect, especially after the first implementation in 1995, with the biomass of six fish species increased and the catch of seven species increased, and the total average biomass and catch increments were 21.22 % and 89.72 %. This positive effect was also reflected after the first adjustment in 2003. Although the moratorium duration was continuously extended after the second and third adjustment, the conservation effect was offset by the flooding of fishing efforts immediately after the moratorium. For the six overexploited stocks, we suggest that the allowable catch of . , . , . , . , . and . is at most 527.91 kt, 147.51 kt, 93.43 kt, 81.51 kt, 1.25 kt and 4.95 kt in the Yellow Sea and Bohai Sea, respectively.
中国政府在黄海和渤海的渔业管理方面出台了许多策略，其中最严格的是夏季休渔。夏季休渔能否恢复渔业资源一直备受关注。在本研究中，我们选取了黄海和渤海8种具有代表性的商业鱼类，包括[此处列举的8种鱼类英文名称未给出中文对应，无法完整翻译]，并采用JABBA方法研究它们的历史开发动态和当前资源状况。我们根据夏季休渔实施及调整后生物量和渔获量的增量来评估其有效性。[此处部分英文表述不完整，无法准确翻译]和[此处部分英文表述不完整，无法准确翻译]种群在2022年处于健康状态，其他六个渔业种群被过度开发。夏季休渔具有很强的保护作用，特别是在1995年首次实施后，六种鱼类的生物量增加，七种鱼类的渔获量增加，总平均生物量和渔获量增量分别为21.22%和89.72%。这种积极影响在2003年首次调整后也有所体现。尽管在第二次和第三次调整后休渔期不断延长，但休渔后立即出现的捕捞努力激增抵消了保护效果。对于六个过度开发的种群，我们建议在黄海和渤海，[此处部分英文表述不完整，无法准确翻译]、[此处部分英文表述不完整，无法准确翻译]、[此处部分英文表述不完整，无法准确翻译]、[此处部分英文表述不完整，无法准确翻译]、[此处部分英文表述不完整，无法准确翻译]和[此处部分英文表述不完整，无法准确翻译]的允许捕捞量分别最多为527.91千吨、147.51千吨、93.43千吨、81.51千吨、1.25千吨和4.95千吨。
