A dramatic recovery has been found on Georges Bank, off New England. Improvements have been found in scallops and redfish, but cod and flounder still remain vulnerable.
The new study looked at 10 areas of the world and found overfishing continues in the North and Baltic seas and the Bay of Biscay.
Despite this bit of good news, 63 percent of the world's fish stocks remain below desired levels.
The study is in Friday's edition of the journal Science.
