The CCAMLR Conservation Measure 41‑06 (2025) regulates the exploratory longline fishery for Dissostichus eleginoides on Elan Bank (Statistical Division 58.4.3a) outside national jurisdiction for the 2025/26 season, defining the area open to fishing through a designated research block and setting a precautionary catch limit of zero tonnes. It prohibits directed fishing, limits operations to longlines, and requires vessels to carry scientific observers, apply seabird‑mortality mitigation, manage by‑catch, and submit daily and fine‑scale catch‑and‑effort reports together with biological data. The measure also mandates fishery‑based research, including tagging at a minimum rate of five fish per tonne and calculation of tag‑overlap statistics, and establishes operational timelines and data‑collection standards to ensure precautionary management and effective monitoring of the exploratory fishery.
