The CCAMLR Conservation Measure 41‑05 (2025) regulates the exploratory longline fishery for Dissostichus mawsoni in Statistical Division 58.4.2 for the 2025/26 season, defining the activity as a one‑year exploratory operation, limiting access to two Australian and two French vessels, and confining fishing to designated research blocks with a precautionary catch limit of 281 tonnes apportioned among them. It sets operational conditions including longline‑only fishing, by‑catch controls, seabird‑mortality mitigation requiring a switch to night setting after three seabirds are caught, and mandatory carriage of at least two scientific observers per vessel. The measure further requires fishery‑based research and tagging at a minimum rate of five fish per tonne, detailed daily and fine‑scale catch‑and‑effort reporting, and biological data collection to support scientific review and monitoring of the exploratory fishery.
