本文介绍了东南太平洋南部公海智利竹筴鱼的探捕、加工情况,并对不同时间、不同海区的探捕生产进行了分析,认为东南太平洋南部公海智利竹筴鱼6～7月份渔场主要集中于38°～41°S之间,其中以39°～40°S为最好,平均网产、日产、CPUE均为最高。6月份的平均CPUE和平均网产、日产呈下降趋势,一直持续到7月上旬,7月中旬开始回升,各项指标呈上升趋势。同时对我国渔船今后生产提出了设想和建议。

This paper introduces the exploration and processing of Chilean mackerel in the high seas of the southeast Pacific Ocean and analyzes the exploration and production at different time and different sea areas. It is concluded that the fisheries of Chilean mackerel in the high seas of South-East Pacific Ocean mainly focus on 38 ° ~ 41 ° S, of which 39 ° ~ 40 ° S is the best, the average net production, Nissan, CPUE are the highest. June average CPUE and average net production, Nissan showed a downward trend, continued until early July, mid-July began to rise, the indicators are on the rise. At the same time, the future production of fishing vessels in China put forward ideas and suggestions.
