Zusammenfassung: | The invention relates to an Argentina squid resource recruitment prediction method, which is characterized in that by using the correlation between a time sequence value formed by marine environment factors of a feeding ground in a feeding month and a CPUE (Catch per Unit Effort) time sequence of the current year, marine environment factors of a sea area with high correlation are selected to act as correlation factors for influences of a feeding and inhabiting environment for Argentina squid resource recruitment; by using the correlation between a time sequence value formed by marine environment factors of a spawning ground in a spawning month and a CPUE time sequence of the next year, marine environment factors of a sea area with high correlation are selected to act as correlation factors for influences of a spawning and inhabiting environment for the resource recruitment; the inhabiting environment appropriateness degrees of the spawning ground and the feeding ground are expressed through the proportion PS |
