North Pacific Ocean squid central fishery predicting method

The invention relates to a North Pacific Ocean squid central fishery predicting method. The method includes time-space scale setting, environmental factor setting and central fishery prediction model establishing. According to the time-space scale setting, three levels of spatial scales and two levels of time scales, namely, a weekly scale and a monthly scale are adopted; according to the environmental factor setting, sea surface temperature (SST) is adopted as a main environmental factor, and two environmental factors, namely sea surface height (SSH), and chlorophyll a (Chl-a), are used in an auxiliary manner, and the environmental factors are divided into four types when a central fishery prediction model is established; a sample scheme set about 24 conditions is established according to the setting conditions of the time-space scales and the environmental factors; and a classical error back propagation (BP) neural network model is adopted as the central fishery predicting model, and the BP neural network m
