为了解渔业资源的时空分布及与海洋环境之间的关系 ,根据 1995～ 2 0 0 1年 6～ 11月西北太平洋海域我国鱿钓生产统计及其表温度数据 ,利用地理信息系统软件和数理统计方法分 3个海区 (14 0°E～ 15 0°E ,15 0°E～ 165°E和 165°E～ 180°E)对柔鱼产量分布、作业渔场与表温关系进行分析。研究表明 ,柔鱼产量主要分布在海区I和II ,且资源密度大 ;在海区III海域产量比重低 ,资源密度也低。 6～ 7月作业渔场广泛 ,平均日产量基本上在 1t /d以下 ;8～ 10月作业渔场集中在海区II,平均日产量基本上在 1.5t/d以上。在同一时期 ,不同海区作业渔场的最适表温有较大差异 ,并表现出自西向东逐渐降低趋势。在海区I,7～ 11月各月最适水温分别为 17～ 19℃ ,18～ 2 2℃ ,17～ 19℃ ,13～ 18℃和 10～ 14℃。在海区II ,6～ 11月各月最适水温分别为 12～ 14℃ ,14～ 17℃ ,15～ 19℃ ,14～ 18℃ ,12～ 15℃和 10～ 13℃。在海区III ,6～ 7月最适表温均为 11～ 15℃。以上结果经非参数统计的K～S检验是可信的。 3个海区柔鱼资源密度、产量分布及其作业渔场形成与各自海洋环境条件有着密切关系。
In order to understand the spatial and temporal distribution of fishery resources and its relationship with the marine environment, according to the statistics of squid fishing production and its table temperature in Northwest Pacific from June to November in 2001 ~ 2001, using GIS software and mathematical statistics Methods The distribution of squid production, relationship between fishing grounds and surface temperature in three seas (14 0 ° E ~ 15 0 ° E, 15 0 ° E ~ 165 ° E and 165 ° E ~ 180 ° E) were analyzed. The results showed that the production of squid was mainly distributed in the sea areas I and II, and the resource density was high. In the sea area III, the yield was low and the resource density was also low. From June to July, the operating fishing grounds were extensive with the average daily output basically below 1t / d; from August to October, the operating fishing grounds were concentrated in the sea area II with the average daily output basically above 1.5t / d. During the same period, there was a big difference in the optimum table temperature for operating fishing grounds in different sea areas, and showed a gradual downward trend from west to east. In the sea area, the optimum water temperature in each month from July to November was 17-19 ℃, 18-22 ℃, 17-19 ℃, 13-18 ℃ and 10-14 ℃ respectively. In sea area II, the optimum water temperature in each month from June to November was 12-14 ° C, 14-17 ° C, 15-19 ° C, 14-18 ° C, 12-15 ° C and 10-13 ° C, respectively. In the sea area III, 6 ~ July the most suitable surface temperature are 11 ~ 15 ℃. The above results by nonparametric K ~ S test is credible. The density and distribution of squidfish resources and the formation of their fishing grounds in the three sea areas are closely related to the respective marine environmental conditions.
