| 摘 要： | 从８０年代初年起，应用实际种群分析法和计算机编程每年对东海绿鳍马面Ｔｕｎ资源量及产量作估算和预报，在１０多年的工作中，利用计算机运算速度不断提高的优势，对评估方法逐步作了改进，根据捕捞方程采用迭代法直接求算捕捞死亡系数Ｆ值，利用反复迭代取消了初始值的估算，使得估算精度和计算便利性都有所提高。实践表明，评估预报结果对渔业生产和管理部门有一定的参考价值。

| Abstract: | Stock assessment and yield prediction of filefish, Thamnaconus septentrionalis (Gunther) in East China Sea has been carrying out every year since early 1980's by using Virtual Population Analysis (VPA) and computer programming. With increase of the computer calculation speed, the assessment method was improved, which increased both the estimation accuracy and convenience. More than 10 years practice showed that the estimated results were useful to the fishing Companies and government management boards |
