1. an Argentinian squid resource magnitude of recruitment Forecasting Methodology, including selecting the marine environment factor and to set up BP network structure pre-Survey model, it is characterized in that utilizing the time sequential value of the marine environment factor composition in Argentina squid forage month feeding ground and thisThe dependency of year CPUE seasonal effect in time series, selects the marine environment factor in dependency height marine site as forage habitat to Ah rootThe correlation factor of court of a feudal ruler squid resource magnitude of recruitment impact;

  • Utilize Argentina squid in the marine environment factor set in month spawning ground of laying eggsThe time sequential value become and next year CPUE seasonal effect in time series dependency, select the marine environment factor in dependency height marine site as productThe ovum habitat correlation factor on Argentina'"'"'s squid resource magnitude of recruitment impact;

    Utilize Argentina squid lay eggs month spawning ground fitPreferably surface temperature scope accounts for ratio P of the gross areaS, forage month feeding ground suitable surface temperature scope account for ratio P of the gross areaF,Use PS

    PFExpress the suitable degree of Argentina'"'"'s feeding ground, squid resource spawning ground habitat;

    Relative coefficient uses PearsonCorrelation coefficient, formula is as follows;
