The three simulated fisheries were estimated by Monte Carlo simulation, the white noises were generated from Box-Muller method; the levels (Coefficient of Variation, CV) were 1%, 10%, 30% and 50%.

• 三种模拟渔业来自蒙特卡罗模拟，白色噪音由Box-Mueller方法发生，其水平(变差系数，coefficient of variation，CV)设为CV=1%25，10%25，30%25和50%25。
