Last year the Commission considered a proposal for a Conservation Measure concerning the adoption of a trade measure that will promote compliance with CCAMLR’s agreed upon rules to bring sustainable fishing. The proposal received the support of all but one State. ASOC would like to support the adoption of this Conservation Measure by the Commission at its XXVII Meeting, and clarify why the adoption of such a measure is a positive step for CCAMLR. ASOC reviews in this paper the relevant international legal framework, and concludes that a measure such as the one proposed does not challenge in any way the existing international legal regime, including neither the rules of the WTO nor the rules and principles of CCAMLR. On the contrary, there is full international support to taking trade measures to combat IUU fishing.
