| Abstract: |
| Most fisheries in China do not have maximum sustainable yield (MSY) estimates due to limited and poor data. Therefore, finding a common method to estimate MSY or total allowable catch (TAC) for fishery management is necessary. MSYs of three important fisheries in the East China Sea were evaluated through a catch-based model. Estimates for intrinsic rate of increase (r) and five levels of process error were considered. Results showed hairtail Trichiurus japonicas (Temminck and Schlegel) and small yellow croaker Larimichthys polyactis (Bleeker) fisheries experienced overfishing from the mid-1990s to the early 2000s, and the suggested TACs were 55.8×104 t and 9.06×104 t, respectively. Decades of overfishing in wintering and spawning grounds of large yellow croaker Larimichthys crocea (Richardson) caused the fishery's collapse in the 1980s, and it has not recovered until today. The Catch-MSY model generated similar estimated MSYs with other methods and may be a useful choice for the assessment of regional stocks in China. |

| 由于数据缺乏等原因，中国大部分渔业种群缺乏最大可持续产量（MSY）和总可捕量（TAC）的评估研究。本文利用一种基于产量数据的Catch MSY模型对东海三个重要渔业MSY进行了评估，利用自然死亡系数M、生长系数k和极限体重W∞等种群参数对内禀增长率r的先验分布进行设定，并考虑了5个水平的过程误差。评估结果显示，东海带鱼和小黄鱼渔业在20世纪90年代中期到21世纪初处于过度捕捞状态，建议的TAC分别为55.8×104t and 9.06×104t。数十年来，对东海大黄鱼越冬场和产卵场的过度捕捞导致该渔业在20世纪80年代崩溃，至今尚未恢复。Catch MSY模型需要较少数据，评估结果与其它方法的评估结果较为一致，可以考虑作为中国近海渔业资源评估方法之一。 |
