摘 要:
利用1995—2001年7~11月表温数据和生产统计数据,采用GIS软件Marine Explorer4.0和统计软件SPSS11.0分析了东太平洋金枪鱼延绳钓大眼金枪鱼钓获率与海水表温之间的关系。结果显示:7月份,81.55%的钓获率分布在表温21—27℃范围内;8月份,93.08%的钓获率分布在表温19~28℃;9月份,93.06%的钓获率分布在表温18~28℃;10月份,76.79%钓获率分布在表温21~27℃;11月份,88.89%钓获率分布在表温21—28℃。同时,利用K-S检验可知,以上分析出来的海水表温(SST)范围基本上可以作为各月份形成渔场的适宜指标之一。[著者文摘]

Abstract:
The relationship between hooking rates of bigeye tuna and sea surface temperature in tuna longline of the East Pacific Ocean was analyzed by Marine Explorer 4.0 and SPSS 11.0 with the environmental data derived from website and fisheries data derived from SPC. The findings showed that the hooking rate is distributing the range of SST 21 - 27 ℃ in July, 19- 28 ℃ in Aug. 18 - 28 ℃ in Sep. 21 - 27 ℃ in Oct. 21 - 28 ℃ in Nov. respectively. K-S test testifies the above temperature range of SST can be referred to one of index of forming fishery ground every month.[著者文摘]
