A method for predicting the quantity of squid resources in the north pacific ocean based on the pacific oscillation index

The invention discloses a method for predicting the quantity of squid resources in the north pacific ocean based on the pacific oscillation index. The method comprises the following steps: obtaining the monthly Pacific oscillation index PDO value of the North Pacific Ocean where the squid is distributed in the North Pacific Ocean in the previous N years; The correlation between squid abundance ln(CPUE) and monthly PDO values in the first N years in the North Pacific Ocean was analyzed by using time series analysis method. The monthly PDO values were obtained as climatic factors affecting theabundance of squid resources in the North Pacific Ocean. Multivariate linear equation was used to establish several abundance prediction models of squid resources in the North Pacific Ocean and to calculate the statistical P value.in the above-mentioned North Pacific resource abundance prediction models, the model with the smallest statistically P value is selected as the optimal model. 本发明种基于太平洋涛动指数的北太平洋鱿鱼资源量预测方法，其包括：获取前N
