The Commission’s decision-making is informed by scientific advice provided by the Scientific Committee and its working groups. Members undertake research, often collaboratively, on many issues such as the Antarctic ecosystem and physical environment, the ecology of key organisms and the impact of fisheries on target species and the ecosystem. CCAMLR also specifies data required from fishing vessels and by scientific observers onboard vessels. Much of the CAMLR Convention Area is in the high seas and therefore data are combined from multiple Members for analyses with results reviewed at meetings of working groups and the Scientific Committee.   

The Commission has divided the Convention Area into a number of smaller areas, each with specific management requirements. Some areas are closed to certain types of fishing activity. Some are open to fishing but are subject to the requirements of conservation measures.

CCAMLR conservation measures include monitoring and compliance systems and tools that ensure that fishing in the Convention Area is conducted in a manner that meets the Convention’s principles of conservation.
