To analysis the suitability of using wind field data for forecasting Pacific saury habitat in the northwest Pacific, this paper use the generalized additive model to fit the habitat suitability index (HSI) for Pacific saury in summer and autumn, based on the Chinese fishery data, environmental data and four types of wind field data included the China-France oceanography satellite (CFOSAT) during June to November in 2019−2020. The result indicates that: (1) Weighted analysis shows distinct seasonal variation of environmental variables on catch per unit effort, with chlorophyll concentration and sea surface temperature having the highest weights in summer and autumn respectively, while wind speed had the lowest weight and direct proportionality to the weight. (2) The average accuracy of the four data in summer and autumn is 68.37% and 76.65% respectively, and CFOSAT reaching the highest accuracy of 80.94% in autumn. (3) The high-HSI areas are consistent with the fishing grounds of Pacific saury, while the HSI high-value regions of scatter meter in autumn seems more robust. There are advantages of using wind speed on the forecast model in autumn, as this model can reflect the influence of transient variation factors on the migration and aggregation of Pacific saury.
