摘要/Abstract

摘要： 根据2009年6月—2012年1月上海金优远洋渔业有限公司在中东太平洋作业的5艘金枪鱼延绳钓渔船的渔捞日志资料，结合卫星遥感反演的海表温度数据，分析了中东太平洋金枪鱼延绳钓渔场的年际和季节变化规律以及渔获量与海表温度的关系。结果表明：在厄尔尼诺年（2009年），金枪鱼延绳钓渔场作业重心会向偏东方向移动，且金枪鱼钓获率较高；而拉尼娜年（2010、2011年）则向偏西方向移动，且钓获率下降；研究海域作业渔场的最适宜海表温度范围为25～30 ℃；2009年最适海表温度略高于2010年和2011年；平均月渔获量与月平均海表温度呈显著正相关（P<0.05）。

Abstract: The present study explored the seasonal and interannual patterns of fishing grounds of tuna longline fishery in the mid-eastern Pacific Ocean according to the catch data of tuna fishing (June 2009 to January 2012) from five vessels of Shanghai Jinyou Fishing Company, and examined the correlations between the catch and sea surface temperature (SST) obtained by satellite remote sensing. The results sho〖JP2〗wed that the location of the central fishing ground shifted from the east in 2009 to the west in 2010 and 2011. In general, the catch rate of tuna and the optimal SST in the central fishing ground were higher in the El Ni-o year (2009) than in the La Ni- years (2010-2011). The optimum range of SST of fishing ground was 25-30 ℃. It was found that the mean catch had a significant positive correlation with the mean monthly SST (P<0.05).
