Aquaculture Opportunity Areas
Aquaculture Opportunity Areas will expand economic opportunities in coastal and rural areas, and increase seafood security.
Overview
An AOA is a defined geographic area that has been evaluated to determine its potential suitability for commercial aquaculture. NOAA will use a combination of scientific analysis and public engagement to identify areas within the AOA that may be environmentally, socially, and economically appropriate for commercial aquaculture.
Identifying Aquaculture Opportunity Areas
NOAA Fisheries developed programmatic environmental impact statements identifying AOAs in U.S. federal waters of Southern California and the Gulf of America* (formerly Gulf of Mexico). We are also working to identify AOAs in Alaska state waters.

Why is NOAA identifying Aquaculture Opportunity Areas (AOAs)?
NOAA has directives to preserve ocean sustainability and facilitate domestic aquaculture in the U.S. through the National Aquaculture Act of 1980, the NOAA Marine Aquaculture Policy, and Executive Order 13921, “Promoting American Seafood Competitiveness and Economic Growth” (May 7, 2020). NOAA has a variety of proven science-based tools and strategies that can support these directives and help communities thoughtfully consider how and where to sustainably develop offshore aquaculture that will complement wild-capture fisheries, working waterfronts, and our nation’s seafood processing and distribution infrastructure.
Identifying AOAs is an opportunity to use best available global science-based guidance on sustainable aquaculture management, and support the “triple bottom line” of environmental, economic, and social sustainability. This approach has been refined and utilized widely within states and by other countries with robust, sustainable aquaculture sectors.
Considering NOAA-trust resources and stakeholder uses of a defined area will help to encourage the sustainable growth of aquaculture by siting aquaculture farms in ways that minimize impacts to those natural resources and reduce user conflicts while maximizing public input in the AOA identification process.
Areas Selected for Focused Evaluation
Starting in 2020, NOAA’s Aquaculture Program began meeting mandates set by the White House and announced the selection of southern California and the Gulf of America as the first regions for focused evaluation to find AOAs. This selection does not mean the entire regions are opportunity areas. Instead, the selection allowed NOAA to deploy our resources to investigate the two regions.
NOAA Announces Regions for First Two Aquaculture Opportunity Areas under Executive Order on Seafood
On June 1, 2023, NOAA announced the beginning of the process to identify AOAs in Alaska state waters, in partnership with the State of Alaska. In Alaska, the effort to identify AOAs will be focused in state waters and NOAA will only consider shellfish and seaweed farming. NOAA will not consider finfish aquaculture during identification of AOAs in Alaska because it is prohibited by state law.

Final Programmatic Environmental Impact Statements for Southern California and Gulf of America
On September 19, 2025 NOAA identified 13 Aquaculture Opportunity Areas totaling more than 21,000 acres in U.S. federal waters of the Gulf of America and off Southern California.

Draft Programmatic Environmental Impact Statements for Southern California and Gulf of America
On November 22, 2024, NOAA released two draft Programmatic Environmental Impact Statements for Southern California and the Gulf of America that bring us one step closer to identifying Aquaculture Opportunity Areas.
Two 90-day public comment periods for each document, and five total public listening sessions, were held for the public to provide feedback, which closed on February 20, 2025.

Notice of Intent
On May 23, 2022, NOAA Fisheries published a Notice of Intent(NOI) in the Federal Register announcing the preparation of the Southern California AOA draft PEIS. The NOI initiated a 60-day public comment period, during which NOAA requested comments concerning the scope of the proposed action to identify an AOA in Southern California. The public comment period lasted from May 23, 2022, to July 22, 2022. For an overview of the public input received during this period, view our Public Scoping Report.

Request for Information
NOAA Fisheries invited public comment on two aspects of AOAs during a 60-day public comment period. The agency requested information on (1) specific areas to consider for the first two AOAs within the Gulf of America and waters off Southern California; and (2) other areas NOAA should consider nationally for future AOAs.

AOA Atlases Released
NOAA has released two Atlases compiling the best available science to inform the identification of AOAs in the Gulf of America and Southern California. Areas in the Atlases have characteristics expected to support multiple types of aquaculture industries including finfish, shellfish, seaweed, or some combination.
NOAA’s National Centers for Coastal Ocean Science developed each Atlas using more than 200 data layers accounting for key environmental, economic, social, and cultural considerations, including fishing interests and marine protected areas. The studies identified nine areas in the Gulf of America and 10 areas in the Southern California Bight that may be suitable for aquaculture, while also reducing conflicts with other ocean uses.

Alaska Updates
Aquaculture Opportunity Area Atlas
On February 19, 2026 The National Centers for Coastal Ocean Science (NCCOS) published an Atlas identifying 77 options (50 to 2,000 acres) for Aquaculture Opportunity Area (AOA) identification across 10 study areas in Gulf of Alaska state waters.

*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.
