Report of research fishing operations at Subarea 48.6 between the 2012/13 and 2023/24 fishing seasons

This paper represents the report of a multi-member longline research fishing on Antarctic toothfish (Dissostichus mawsoni) in Subarea 48.6 between 2012/13 and 2023/24 fishing seasons by Japan, Spain, and South Africa. Since the beginning of the structured research plan in 2012/13 fishing season, there have been different year cycles of the plan, the current proposal (2021/22-2023/24) being the fourth research proposals in Subarea 48.6. The periodic cycles of the plans are from 2012/13-2014/15, the second from 2015/16-2017/18 and the third from 2018/19-2020/21. The data set, C2 and Observer data, were provided by the CCAMLR Secretariat on the 7th of August, 2024. In this paper, the data set during current fishing season (2023/24) were used for reporting the quantity of data, samples collected, and results of quick analysis as a progress toward research millstones.
