Cod stocks refer to the populations of cod, a popular fish species found in the North Atlantic Ocean. These stocks are important for both commercial fishing and ecological balance. Overfishing and environmental changes have led to significant declines in some cod populations, particularly in areas like the Northwest Atlantic. Efforts to manage and restore cod stocks include implementing fishing quotas, protecting spawning grounds, and promoting sustainable fishing practices. Monitoring these stocks is crucial for ensuring the long-term health of the fishery and the marine ecosystem, as well as supporting the livelihoods of communities that depend on cod fishing.
