根据2004年5—11月我国鱿钓船在北太平洋生产数据,结合表温资料,按经纬度1°×1°的格式,利用Marineexplorer4.0软件作图进行分析。结果表明,5—7月在160°E以东海域作业,产量较低;8—10月在150°—160°E海域作业,为生产作业的产量高峰期,占总产量的62.5%;11月在150oE以西海域作业,产量也较低。在150°E以西海域CPUE最高,150°—160°E中部海域次之,160°E以东海域最低。作业渔场的适宜表温呈现出季节性变化。各月适宜表温分别为:5月12℃～14℃;6月15℃～16℃;7月14℃～16℃;8月18℃～19℃;9月16℃～17℃;10月15℃～16℃;11月12℃～13℃。K-S检验表明,上述表温可作为寻找中心渔场的指标。
According to the production data of squid fishing vessels in the North Pacific Ocean from May to November in 2004 and the data of surface temperature and the latitude and longitude of 1 ° × 1 °, the data were analyzed by using Marineexplorer 4.0 software. The results show that from May to July, the output was lower in the east of 160 ° E with a lower yield; from August to October in the sea area of 150 ° -160 ° E, it was the peak output of production operations, accounting for 62.5% of the total output; Month 150oE west of sea operations, production is also lower. In the west of 150 ° E, the CPUE was the highest, followed by the middle 150 ° -160 ° E and the lowest east 160 ° E. The suitable surface temperature of the operation fishing ground shows a seasonal change. The appropriate monthly table temperatures are: May 12 ℃ ~ 14 ℃; June 15 ℃ ~ 16 ℃; July 14 ℃ ~ 16 ℃; August 18 ℃ ~ 19 ℃; September 16 ℃ ~ 17 ℃; October 15 ℃ ~ 16 ℃; November 12 ℃ ~ 13 ℃. K-S test showed that the above table temperature can be used as an index to find the center fishery.
