status of major fish stocks.

"A biological fish stock is a group of fish of a single species that live in the same geographic area and mix enough to breed with each other when mature. A management stock may refer to a biological stock, or a multispecies complex that is managed as a single unit. The Status of Major Fish Stock indicator classifies management stocks into Healthy, Cautious and Critical zones, as outlined in the Fishery Decision-Making Framework Incorporating the Precautionary Approach (2009) (hereafter referred to as the precautionary approach). For those stocks in the Healthy zone (i.e., above the Upper stock reference point, which is determined by the productivity objectives of the fisheries), fisheries management decisions and harvest strategies are designed to maintain fish stocks within this zone, while providing sustainable economic, social and cultural benefits. For fish stocks in the Cautious zone (i.e., between the Upper stock reference point and the Limit reference point), decisions and strategies promote stock rebuilding to the Healthy zone. In the Critical zone (i.e., below the Limit reference point, which is the stock level below which productivity is sufficiently impaired to cause serious harm to the resource), stock growth is promoted and removals are kept to the lowest possible level"--Description, p. 6.
