摘　　要：１９９６年７～１０月份在西北太平洋作业的鱿鱼钓船经济效益普遍不太好，主要原因是渔场鱿鱼分布稀疏时，钓机的ＣＰＵＥ（单位努力渔获量）低。相比之下，手钓的ＣＰＵＥ却较高。笔者分析了在原抖动方式下，鱿鱼稀疏时鱿鱼钓机的ＣＰＵＥ较手钓的ＣＰＵＥ低的原因，进而对钓机原抖动方式提出了改进意见，并对改进方案的可行性进行了探讨。The output of squid jigging boats in Northwest Pacific during the time of July and October in 1996 was low. The main reason is that when squid resource is poor, the CPUE of jigging machines is low too. On contrast with it, the CPUE of manual fishing is comparatively high. In this paper the authors discuss the reason why the CPUE of jigging machines is lower than that of manual fishing on poor squid resources and the improvement on shaking way of jigging machines as well as its feasibility.
