Joint report on exploratory fishing in Divisions 58.4.1 and 58.4.2
Robust stock assessments and catch limits according to CCAMLR decision rules remain to be determined for Divisions 58.4.1 and 58.4.2, and precautionary management arrangements are in place as set out in Conservation Measures 41-11 and 41-05. Multiple exploratory fishing research plans are currently...
