Using Chinese squid fishing production data during the main fishing season from 1999 to 2004 in the waters of 150—165°E, the present study combines the sea surface temperature with the horizontal gradient and the percentage of fishing times and daily catch as the suitability index. Using arithmetic mean model and geometric mean model, the integrated habitat suitability index is established based on SST and GSST .
