Prediction method and application of squid resource abundance based on Pacific Oscillation Index

摘要

Based on the Pacific oscillation index, a method and application for predicting the abundance of sea squid resourcesObtaining the monthly Pacific Oscillation Index PDO value of the sea area where the squid was distributed in the past n yearUsing time series analysisA correlation analysis was carried out for the PDO value of the pineal resource abundance CPUE in the past n years.Select the PDO value of the moon showing statistically significant correlationThe PDO values of these selected months are sequentially numberedX1,X2X3Against any 1 to m climate factorsUsing a multivariate linear equation, we developed a model for predicting the maximum abundance ofCalculating P values for each prediction modelSelecting a model with the smallest p value as an optimal model and.The present invention realizes the prediction of the abundance of sea squid resources using the Pacific Oscillation Index PDO value, and serves as a guidance in fishery production, improves the fishing efficiency, reduces the fishing cost, and expects the future.Diagram
