I want to know the answer to the following question:
When did the Convention for the Conservation of Antarctic Marine Living Resources  come into force?
All the background I'm provided with is that "The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR), a treaty that came into force in 1980, requires that regulations managing all Southern Ocean fisheries consider potential effects on the entire Antarctic ecosystem.". Is that enough to answer the question?
Answer: yes
