Map of Madison and Swanson sites and Steamboat Lumps, and the Edges fishery management areas. This map was created prior to Executive Order 14172 and shows the area formerly known as the Gulf of Mexico. The name is now Gulf of America. This change did not result in any changes to, and had no effect on the applicability or enforceability of, any existing regulations.

The Southeast Region, Sustainable Fisheries Division is responsible for managing commercial and recreational fisheries in the southeastern United States and the U.S. Caribbean under the Magnuson-Stevens Fishery Conservation & Management Act.

These seasonal/area closure maps and Geographic Information Systems (GIS) data represent areas that include the Gulf of America:

Title 50, Code of Federal Regulations, Part 622—Fisheries of the Caribbean, Gulf of America, and South Atlantic

For the precise legal definition of the fishery management plan and geographic coordinates, please consult Subpart B:

Section 622.34 Seasonal and area closures designed to protect Gulf reef fish (a) Closure provisions applicable to the Madison and Swanson sites and Steamboat Lumps, and the Edges

The CFR should be consulted for the precise legal definition of fishery management areas and geographic coordinates. Esri's ArcGIS software or Google Earth can be used to open GIS shapefiles. Google Earth can also be used to open zipped KML (KMZ) files to view the management areas. Click here to download Google Earth. Metadata (information about the GIS shapefile data) is available in XML or an easy-to-read HTML format, and is included in the zipped shapefile.

*Executive Order 14172, “Restoring Names That Honor American Greatness” (Jan. 20, 2025), directs that the Gulf of Mexico be renamed the Gulf of America. On August 7, 2025, NOAA Fisheries and the National Ocean Service amended regulations in the Code of Federal Regulations to reflect the renaming. The name change did not result in any changes to, and had no effect on the applicability or enforceability of, any existing regulations. This website continues to use “Gulf of Mexico” when quoting statutes or previously published materials.
