Reviewing stock hypothesis of Antarctic toothfish (Dissostichus mawsoni) as a part of 2021/22-2023/24 research plan in Subarea 48.6

All of the additional data and findings during ongoing research program period exploratory fishery in the Subarea 48.6 (2021/22-2023/24) support the existing stock hypothesis of Antarctic toothfish (Dissostichus mawsoni). Updated data and insights suggest that adult migration is infrequent, and stock structure of D. mawsoni in the Weddel Sea is primarily determined by the migration of juveniles.
