| Abstract: |
| It is important to find a reliable method to estimate maximum sustainable yield (MSY) or total allowable catch (TAC) for fishery management, especially when the data availability is limited which is a case in China. A recently developed method (CMSY) is a data-poor method, which requires only catch data, resilience and exploitation history at the first and final years of the catch data. CMSY was used in this study to estimate the biological reference points for Largehead hairtail (Trichiurus lepturus, Temminck and Schlegel) in the Yellow Sea and Bohai Sea, based on the fishery data from China Fishery Statistical Year Books during 1986 to 2012. Additionally, Bayesian state-space Schaefer surplus production model (BSM) and the classical surplus production models (Schaefer and Fox) performed by software CEDA and ASPIC, were also projected in this study to compare with the performance of CMSY. The estimated MSYs from all models are about 19.7×104-27.0×104 t, while CMSY and BSM yielded more reasonable population parameter estimates (the intrinsic population growth rate and the carrying capacity). The biological reference points of B/BMSY smaller than 1.0, while F/FMSY higher than 1.0 revealed an over-exploitation of the fishery, indicating that more conservative management strategies are required for Largehead hairtail fishery. |

| 估计最大可持续产量（maximum sustainable yield，MSY）或总可捕量（total allowable catch，TAC）的可靠方法在渔业管理中十分重要，尤其是对中国这样的渔业数据贫乏的情况。最近发展的一种聚焦于数据贫乏的方法（CMSY）仅需要渔获量、恢复力和开发历史的数据。本研究基于1986-2012年《中国渔业统计年鉴》的渔业统计数据，使用CMSY估算了黄渤海带鱼（Trichiurus lepturus， Temminck and Schlegel）的生物学参考点。本研究使用了贝叶斯状态空间Schaefer剩余产量模型和经典剩余生产模型（Schaefer和Fox模型）（使用CEDA和ASPIC软件计算）同CMSY的评估效果进行了比较。MSY的估计值约为19.7×104-27.0×104 t，CMSY和BSM估计得到的种群参数（内秉增长率和环境容纳量） 更为合理。结果表明生物学参考点B/BMSY小于1.0，F/FMSY大于1.0，所以该渔业处于过度捕捞状态，建议采取更保守的渔业管理策略。 |
