MSY has been especially influential in the management of renewable biological resources such as commercially important fish and wildlife. In fisheries terms, maximum sustainable yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions. [22]
Sustainability can mean different things to different people. Some may view sustainable fishing to be catching very little in order for fish populations to return to their historical levels (represented by the upper left green area), while others consider sustainability to be the maximum amount of fish we can catch without depleting stocks any further (red dot).
For many of these stocks, the fishing moratorium started more than a decade ago, however two stocks (redfish and cod) were reopened to fishing after decade-long moratoria. NAFO co-manages the pelagic redfish in Subarea 2 and Div. 1F-3K (off Greenland) with its sister organization, NEAFC.
