根据２０００年５－７月北太平洋鱿钓探捕调查所收集的海水盐度、温度及渔获量等数据，分析了调查海域表层盐度、不同水层水温的分布特征及鱿钓渔场的形成。利用聚类和相关分析方法，研究了单位捕捞努力量渔获量与表层盐度及不同水层水温的关系。结果表明，鱿钓渔场形成于表层低盐水舌和１００ｍ层水温暖水舌的交汇区，单位捕捞努力量渔获量与１００ｍ层水温相关性最好，但表层海水盐度的分布对鱿钓渔场的确定仍具有一定指示意义。
Based on the data of seawater salinity, temperature and catch collected in the North Pacific squid fishing investigation from May to July in 2000, the distribution of surface salinity, water temperature at different water layers and the formation of squid fishing grounds were analyzed . Using cluster analysis and correlation analysis, the relationship between catch of unit fishing effort and surface salinity and water temperature of different water layers was studied. The results showed that the squid fishing farm was formed at the intersection of the surface saltwater tongue and the warm water tongue of 100m layer water. The correlation between fishing effort and water temperature of 100m layer was the best. However, the salinity distribution of surface seawater had a negative influence on squid fishing grounds The determination still has some indication.
