To protect fish stocks, Atlantic countries have implemented several management tools to regulate fishing activity within their territorial waters and 200-nautical-mile exclusive economic zones. These measures include:1
- Catch Limits and Quotas: Authorities establish annual limits on the total allowable catch for specific species, which are often allocated among fishing fleets or member states to ensure sustainability.12
- Area Closures and Marine Protected Areas (MPAs): Governments designate specific regions as protected zones where fishing is restricted or prohibited entirely to provide safe havens for biodiversity and migrating species.13
- Time and Season Restrictions: Fishing is often limited to specific times of the year to protect stocks during critical periods, such as spawning seasons.1
- Permits and Monitoring: Access to fisheries is controlled through permit systems, and monitoring programs—sometimes involving observers aboard vessels—are used to enforce regulations and track compliance.12
- Gear Regulations: To reduce bycatch, countries have implemented technical requirements, such as the use of turtle excluder devices, acoustic pingers, and the prohibition of large-scale drift nets.4
While these tools are essential for conservation, their success has been limited, as many Atlantic fish stocks remain overfished.1
