According to the squid catch data in North Pacific within two years of 1994 and 1995, the relationship between catch and fishing time,position and water temperature is analyzed, and some characters of Ommastrephes bartrami fishing ground are obtained.It is inferred that the best time for fishing Ommastephes bartrami in North Pacific is around September. It is possible to have good catch shifting the fishing ground from south to north before the middle days of September and vice versa after middle days of September.The weight range is 200 g to 400 g in July, and more than 600 g after September. The realtionship between the surface temperature and catch is not very clear, it is necessary to get temperature at 50 m and 100 m in depth for comparing analysis.
