On above parameters, the utilization situation is simulated by dynamic synthetic model, and the result show that the stock of Scomber japonicus has been severely overfished.

By comparing Scomber japonicus's growth status of different periods, the growths of 1960 ', 1980' and 2000 'are similar, but that of 1970' is obviously different.

比较不同时期鲐鱼的生长情况显示，20世纪60、80年代和21世纪初期鲐鱼的生长较接近，而20世纪70年代的鲐鱼生长情况与其他3个时期的鲐鱼生长相差较大。
