Q

What must all vessels in the CCAMLR region participate in?

A

Monitoring systems to report krill catches

38
Q

Why are pharmaceutical companies interest in Antarctic species?

A

For their anti-freeze proteins in the blood, and for how fish slow their heartbeat to save energy in cold environments
