摘　　要：基于2020年的监测数据,对东南太平洋公海鱿鱼钓的渔业状况进行了分析。结果表明:东南太平洋公海鱿鱼钓按其作业海域可分为赤道渔场、中部渔场和南部渔场,总体而言,其中靠近专属经济区外侧公海的渔获量较高;渔期为全年,其中赤道渔场渔期为1-3月,中部渔场渔期主要为6-8月,南部渔场渔期主要为4-5月与10-11月;渔获组成以茎柔鱼为主,约占年总渔获量的99.51%;渔获量的月间分布以7月最高,12月最低,分别占全年总渔获量的20.48%与1.50%,空间分布以中部渔场与赤道渔场为主,两者分别占全年总渔获量的39.28%与38.44%。Based on the monitoring data in 2020,the fishery status of squid fishing in high seas of the Southeast Pacific Ocean was analyzed.The results showed that according to its fishing area,the squid fishing ground in high seas of the southeast Pacific Ocean could be divided into equatorial fishing ground,central fishing ground and southern fishing ground,generally,the catch in the high seas was higher when the fishing ground was closer to the Exclusive Economic Zone.The fishing period was year-round,with the equatorial fishing ground from January to March,the central fishing ground mainly from June to August,and the southern fishing ground mainly from April to May and October to November.The catch composition was dominated by Dosidicus gigas,accounting for about 99.51%of the total annual catch weight.The monthly distribution of catch weight was the highest in July and the lowest in December,accounting for 20.48%and 1.50%of the total catch weight of the whole year respectively.The spatial distribution of catch weight was dominated by the central fishing ground and the equatorial fishing ground,which accounted for 39.28%and 38.44%of the total annual catch weight respectively.
