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,评估和预报结果对渔业生产和管理部门有一定的参考价值。
From the early 1980s onwards, the actual population analysis method and computer programming are used to estimate and forecast the resources and yield of the green fins in the East China Sea each year. In more than 10 years of work, taking advantage of the increasing speed of computing, And gradually improved. According to the fishing equation, the fishing mortality coefficient F was directly calculated by iterative method, and the initial value was canceled by repeated iterations, which improved the estimation accuracy and convenience of calculation. Practice shows that the assessment and forecast results have certain reference value for the fishery production and management department.
