基于Argo数据的中西太平洋鲣渔获量与水温、表层盐度关系的初步研究

根据上海金汇远洋渔业公司2007年度在中西太平洋海域进行鲣Katsuwonus pelamis围网作业的生产数据以及Argo剖面浮标数据，利用地理信息系统软件Arcview，按1°×1°的格式绘制了各月产量、表层温度、表层盐度以及50m和200m水层温度等，并对数据进行了综合分析。结果表明：鲣的高渔获量区域主要分布于150°～153°E、160°-161°E，0°～2°S的水域；2007年最高月产量和最高单网平均日产量（CPUE）的月份分别为8月和2月；通过K—S检验，2007年最适表层温度为29．3～30．1℃，最适表层盐度为34．0～35．2；0～200m、50～200m水层的垂直温差为11℃时，渔获量达到最大。Shapiro—wilk正态性检验结果表明，渔获量与0—200m、50—200m水层的垂直温差服从正态分布关系。上述结论符合生产实践中获得的情况，表明Argo数据可以应用于渔业生产和科研中。

The relationship between skipjack Katsuwonus pelamis catch and water temperature and surface salinity in the west-central Pacific Ocean based on Argo data

The distribution maps with format of 1° latitude by 1° longitude include month production maps of skipjack Katsuwonus pelamis and distribution maps were drawn by Arcview, showing the relationship between monthly production and surface temperature, and surface salinity in depth of 50 m, and 200 m every month, based on skipjack purse data in the west -central Pacific Ocean by Shanghai pelagic fishery company and Argo profile data in 2007. The results showed that the high catch was mainly observed in 150 - 153°E,160 - 161°E,0° -2°S in 2007. The maximal catch was found in August, but the highest CPUE in Fehruary. With Kolmogorov - Smimov two sam- ple test methods, the most optimum surface temperature was 29.3 - 30.1 ℃ and the optimum surface salinity 34. 0 - 35.2. The maximal catch appeared at difference temperature of 11 ℃ between 0 - 200 m and 50 - 200 m. The Shapiro- Wilk normality test showed that the distribution of difference temperature in production followed norm school. The above results are accorded with the instance of production practice, indicating that Argo data can be used in fishery production and research.
