智利外海茎柔鱼产量分布及其与表温的关系

Catch distribution of jumbo flying squid and its relationship with SST in the offshore waters of Chile

根据2004年4～6月我国鱿钓船在智利外海生产统计数据和表温资料,用Marineexplore4.0绘制各月产量、CPUE与表温关系的分布图并进行分析。结果表明,4～6月茎柔鱼产量主要分布在28°～30°S、76°～78°W附近海域,平均CPUE在10t/d以上。作业渔场的表温范围为17～20℃,主要集中在表温为17～19℃海域。

Based on the catch data of Chinese squid jigging vessels in the offshore waters of Chile from April to June in 2004, the production and catch per day distribution and its relationship with SST with the format of 1° latitude by 1° longitude were analyzed by Marine explorer 4.0. The results indicated that the catch mainly concentrated in the waters near 28～30°S,76～78°W, the average CPUE was more than 10 t/d. The SST ranged from 17℃ to 20℃ in the fishing grounds, but mainly located in waters between 17℃ and 19℃.
