摘要
根据１９９４年、１９９５年北太平洋鱿鱼钓生产船的渔获资料，分析了渔获量与作业时间、经纬度、水温等之间的关系，得出了北太平洋红鱿鱼渔场的一些特征。北太平洋红鱿鱼渔获旺发期在每年的９月份前后；９月中旬以前作业渔场可以逐步从南向北移，９月中旬以后渔场逐步从北向南移，能获得较好的产量；７月份的鱼体重量以２００～４００ｇ为主，９月份以后则以６００ｇ以上为主；海水的表面温度与渔获量之间的关系不十分明显，有必要测量水深５０、１００ｍ的温度做比较分析。
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.
