The Academy of Fisheries Science in Korea is conducting voluntary research on Patagonian toothfish (mero) in the Southwest Atlantic Ocean to promote responsible deep-sea fishing. The research involves tracking the short-term and long-term movements of 50 mero specimens using satellite electronic labels, which have revealed that the fish migrate from the Falklands to South Georgia. This research is expected to be used as basic data for evaluating the resource status of mero by a regional fisheries management organization, and could be beneficial to Korea when catch quotas are allocated.
