摘要: 本文根据北太平洋渔业委员会(North Pacific Fisheries Commission,NPFC)1995—2014年全球秋刀鱼(Cololabis saira)生产统计数据和美国夏威夷大学网站的黑潮(Kuroshio current,KC)、亲潮(Oyashio current,OC)及其交汇区(Transition zone,TZ)的海表面温度(Sea surface temperature, SST)和海表面温度异常(Sea surface temperature anomaly, SSTA)数据,利用关联度法和频次统计法分析了秋刀鱼资源丰度与黑潮、亲潮及其交汇区SST和SSTA的关系。结果表明,秋刀鱼资源丰度年间变化较大,呈现出“大小年”的现象;各月份水温因子(SST KC1表示黑潮区1月SST,SSTA OC7表示亲潮区7月SSTA)与秋刀鱼资源丰度关联度均在0.6以上,关联度较高,大小顺序依次为SSTAKC1>SSTAOC7>SSTAOC9>SSTATZ6>SSTATZ5>SSTATZ4>SSTAOC8>SSTAKC2>SSTOC9>SSTKC3>SSTKC2>SSTTZ6>SSTTZ5>SSTOC8>SSTKC1>SSTTZ4>SSTOC7>SSTAKC3,SSTA的关联度普遍高于SST,其中SSTA的适宜范围为0~1.5℃,SST的适宜范围为14~20℃;K-S检验(P<0.01)结果表明SSTA和SST的适宜范围是合适的。本文主要对黑潮、亲潮及其交汇区海域水温与秋刀鱼资源丰度的关系进行研究,研究内容可使我国提前掌握秋刀鱼资源丰度异常变动的情况,为合理安排捕捞努力量提供帮助。

Abstract: Based on the 1995—2014 global Cololabis saira catch data collected by North Pacific Fisheries Commission,sea surface temperature (SST) and sea surface temperature anomaly (SSTA) of the Kuroshio Oyashio and Kuroshio-Oyashio Transition Zone from the website of Hawaii University, this paper analyzed the relationship between C. saira resource abundance and SST and SSTA of the Kuroshio, Oyashio and Kuroshio-Oyashio Transition Zone by using the method of grey relation analysis and frequency statistic. The results indicated that the inter-annual variation of C. saira dramatically presented an “on and off-year” phenomenon. The correlation of temperature factor in each month and the saury resource abundance correlation was high and all above 0.6, the order was in turn: SSTAKC1>SSTAOC7>SSTAOC9>SSTATZ6>SSTATZ5>SSTATZ4>SSTAOC8>SSTAKC2>SSTOC9>SSTKC3>SSTKC2>SSTTZ6>SSTTZ5>SSTOC8>SSTKC1>SSTTZ4>SSTOC7>SSTAKC3, and SSTA correlation degree was generally higher than that of SST. The optimum range of SSTA and SST were 0~1.5℃ and 14~20℃, respectively. According to K-S test (P<0.01), the range of SSTA and SST were reasonable. The research content could help the Chinese mainland master saury resource abundance abnormal changes ahead of time, which helps to arrange fishing effort reasonably.
