Abstract: In this paper,effect of inter-annual change in sea surface water temperature and Kuroshio on fishing ground of squid Ommastrephes bartramii was studied based on the fishing data by Chinese squid jigging boats between June and November from 1998 to 2007.The results showed that the area with more than 5% of the total catch was distributed in the longitude direction as follows： 171°-174°E and 176°-180°E in June,157°-161°E,167°-169°E and 179°-180°E in July,151°-158°E in August,152°-160°E in September,146°-147°E and 151°-160°E in October,145°-148°E and 150°-156°E in November.In the latitude direction,however,the area with more than 20% of the total catch was found in the waters as follows： 39°-41°N in June,40°-42°N in July,41°-44°N in August,42°-45°N in September,42°-44°N in October and 40°-42°N in November.The more change in fishing ground was observed in the latitude than that in the longitude.The reasons for changeable fishing ground were attributed to the inter-annual change in SST（the large standard deviation of SST in the same month） and the Kuroshio.When there was a large bending with Kuroshio,the sea surface temperature were generally lower in the waters from 150°to 160 E,the fishing ground were widely distributed,with a lower CPUE.However,when there has been a small bend with Kuroshio,the case was the opposite.
