The CCAMLR Conservation Measure 41‑04 (2025) regulates the exploratory longline fishery for Dissostichus mawsoni in Statistical Subarea 48.6 for the 2025/26 season, defining the species, area, season and authorised participants (Japan, Spain and Korea, with no more than one vessel per flag State operating at a time). It sets a precautionary catch limit of 713 tonnes allocated across designated research blocks, prohibits offal discharge, and requires by‑catch controls and seabird‑mortality mitigation, including an obligation to switch to night setting after three seabirds are caught. The measure mandates fishery‑based research and tagging at a minimum rate of five fish per tonne, carriage of at least two scientific observers per vessel, and detailed daily and fine‑scale catch‑and‑effort reporting together with biological data collection to support monitoring and scientific assessment of the exploratory fishery.
