摘 要:根据 2 0 0 1年 2~ 8月我国鱿钓船在西南大西洋的生产数据 ,结合表温资料 ,按经纬度 1°× 1°的格式进行分析 ,利用MarineExplorer4 .0软件作图。结果表明 ,产量主要集中在 6 0°W、4 5°S附近的公海渔场 ,2~ 3月为产量高峰期 ;4~ 5月产量开始下降 ;6~ 8月产量急速下降。在福克兰群岛海域平均日产量较高。作业渔场的表温呈现出季节性变化 ,2~ 6月平均每月下降约 1.2℃。用K -S检验法对各表温值所累加的出现频度进行检验 ,结果表明表温与CPUE的差异性不大。Based on the production database of Chinese squid fishing vessels and the sea surface temperature with the format of 1° latitude by 1° longitude, the distribution maps were drawn by Software Marine Explorer 4.0. The results show that the central production area was around 45°S、60°W; that the summit of production was in Feb. and March; that the production began decline during April and May; that it was very low from June to August. The higher CPUE are located around Falkland Islands. The SST in fishing grounds seems to change seasonly and falls 1.2 ℃ every month from Feb. to June in average. The result of K-S test shows that the differences between sea temperature and CPUE are not remarkable.
