Abstract

Abstract:

In this study, patio-temporal distribution of Pacific Saury （ Cololabis saira） and its correlation with SST （ sea surface temperature） in the Northwestern Pacific from July to September 2005 were investigated with the GIS software of Marine Explorer 4.0 on a weekly by a grid of 1°× 1° scale. The results indicated that the fishing ground varied with a tendency of moving from Southwest to Northeast during this period. SST in the fishing grounds ranged from 11 to 15℃ with the optimum of 12-13℃. Krnskal-Wallis test showed that there were not significant differences in CPUE among temperatures during surrey period.

Key words: cololabis saira, fishing ground , northwestern pacific , SST

摘要：

根据2005年7月中旬砷月下旬西北太平洋公海秋力鱼生产调查资料及其表温度数据，按周及经纬度10×1°时空分辨率，利用GIS（渔业地理信息系统）软件Marine Explorer4．0和数理统计方法对西北太平洋公海秋刀鱼作业渔场分布及其与表温的关系进行了初步分析。结果表明，各周作业渔场的分布变化较大，且呈西南向东北变化的趋势。作业渔场分布在表温为11～15℃的海域，最造作业表温为12—13℃。调查期间各个温度组作业CPUE（单位捕捞努力量渔获量）不存在显著性差异。
