Aquaculture
Marine aquaculture (or farmed seafood) is vital for supporting our nation’s seafood production, year-round jobs, rebuilding protected species and habitats, and enhancing coastal resilience. Aquaculture—the breeding, rearing, and harvesting of animals and plants in all types of water environments—is one of the most resource-efficient ways to produce protein and has helped improve nutrition and food security in many parts of the world. Globally, aquaculture supplies more than 50 percent of all seafood produced for human consumption—and that percentage will continue to rise.
At NOAA Fisheries, we support cutting-edge science and research as well as federal policy making and regulation to grow sustainable aquaculture in the United States and reap its social, economic, and environmental benefits while supporting commercial and recreational fisheries. We foster responsible aquaculture that provides safe, sustainable seafood; creates employment and business opportunities in coastal communities; and complements NOAA’s comprehensive strategy for maintaining healthy and productive marine populations, ecosystems, and vibrant coastal communities.

U.S. Aquaculture
We are working hard to foster the growth of aquaculture in the United States not only to help meet U.S. seafood demand, but also to help encourage job growth. We are involved in a variety of aquaculture activities around the country and offer assistance through our regional aquaculture coordinators.
Global Aquaculture
Fisheries and aquaculture remain important sources of food, nutrition, income and livelihoods for hundreds of millions of people around the world. World per capita fish supply reached a new record high of 20 kg in 2014, thanks to vigorous growth in aquaculture, which now provides half of all fish for human consumption, and to a slight improvement in the state of certain fish stocks due to improved fisheries management.
Shellfish Aquaculture
Shellfish farming and restoration is critical to get more oysters, clams, and mussels in the water for food, jobs, and ecosystem services. We are working with partners to address environmental research, spatial planning, permitting, restoration, and farming techniques for shellfish aquaculture.

Understanding Marine Aquaculture
The United States has a small and vibrant commercial marine aquaculture industry supported by world class research and technology.

Regulation & Policy

United States marine aquaculture operates within one of the most comprehensive regulatory environments in the world. Projects that are sited in U.S. waters must meet a number of federal, state, and local regulations that ensure environmental protection, water quality, and healthy oceans.
NOAA Fisheries plays a central role in developing and implementing policies that enable marine aquaculture, and works to ensure that aquaculture complies with existing federal laws and regulations that NOAA enforces under its marine stewardship mission.
Science and adaptive management inform NOAA policy, regulatory, and management decisions regarding aquaculture in marine waters.
Regulations
NOAA conducts regulatory activities for marine aquaculture under a suite of federal statutes designed to sustain healthy oceans. The agency also engages in consultations with other agencies that issue permits for aquaculture activities in state and federal waters.
The National Aquaculture Act of 1980 established aquaculture as a national policy priority for the United States and created the Interagency Working Group on Aquaculture as the institutional structure through which NOAA coordinates with other federal agencies on aquaculture-related activities.
Opportunities for More Efficient Permitting of Commercial Shellfish Aquaculture
Executive Order on Promoting American Seafood Competitiveness and Economic Growth
Section 6 of Executive Order 13921, Promoting American Seafood Competitiveness and Economic Growth (May 7, 2020), states that NOAA will serve as the lead agency for National Environmental Policy Act (NEPA) review for aquaculture projects when the projects meet all three of the following criteria:
- located within the EEZ and outside of the waters of any State or Territory,
- require environmental review or authorization by two or more (federal) agencies, and
- the agency that would otherwise be the lead agency has determined that it will prepare an environmental impact statement (EIS).
For purposes of Executive Order 13921, environmental review is the agency procedures and processes for preparing a document required under NEPA. Authorization is any license, permit, approval, finding, determination, or other administrative decision issued by an agency that is required or authorized under Federal law in order to site, construct, reconstruct, or commence operations of a covered project administered by a Federal agency. This includes Marine Mammal Protection Act incidental take authorizations and consultations under the Endangered Species Act and the Magnuson-Stevens Fishery Conservation and Management Act (MSA).
As lead agency, NOAA would ultimately be responsible for completing the NEPA EIS process. Per the E.O. and consistent with One Federal Decision process enhancements described in section 5(b) of Executive Order 13807, NOAA would be responsible for navigating the project through the Federal environmental review and authorization process and preparing a permitting timetable for the project that is made publicly available on its website. NOAA must also identify a primary point of contact at each cooperating and participating agency. All individual agency decisions shall be recorded in one Record of Decision (ROD), unless the project sponsor requests that agencies issue separate NEPA documents, the NEPA obligations of a cooperating or participating agency have already been satisfied, or the lead agency determines that a single ROD would not best promote completion of the project's environmental review and authorization process.
The U.S. Army Corp of Engineers and Environmental Protection Agency remain the main permitting agencies for aquaculture. These agencies, and NOAA if a NOAA permit is required consistent with NOAA's authority under MSA, would consider the specifics of a proposed aquaculture project to determine whether an EIS is appropriate, and if so, NOAA would assume the EIS lead agency role. The E.O. does not prescribe that NOAA serve as lead agency for a NEPA Environmental Assessment.
Interagency Subcommittee on Aquaculture
NOAA is a co-chair of the Subcommittee on Aquaculture (SCA). The SCA coordinates federal agencies to increase the overall effectiveness and productivity of federal aquaculture research, regulation, technology transfer, and assistance programs.

National Strategic Plan for Federal Aquaculture Research
National Shellfish Initiative
The National Shellfish Initiative aims to increase populations of bivalve shellfish (oysters, clams, and mussels) in our nation's coastal waters through commercial production and conservation activities. Efforts focus on encouraging shellfish aquaculture, advancing science and research, and streamlining permitting at federal, state, and local levels.
Inspired by this national initiative, the Washington State Shellfish Initiative was the first partnership of federal and state agencies, tribes, the shellfish industry, and the restoration community to restore and expand shellfish resources to promote shellfish aquaculture and create family-wage jobs.
Today there is a growing number of state shellfish initiatives including California, Connecticut, North Carolina, and Rhode Island. Alaska has also launched a mariculture initiative to expand both shellfish and seaweed farming in the state.
Science & Technology
We are working to address the technical and scientific barriers of marine aquaculture and to provide science information for management in a number of ways, including through in-house research at NOAA, grants and cooperative agreements with Sea Grant and other stakeholders, and by coordinating research with other federal agencies.
Aquaculture Research at NOAA Fisheries
Several NOAA Fisheries Science Centers explore a wide spectrum of issues including the culture of specific species, life-cycle analysis, alternative feeds, ocean acidification, and habitat benefits and impacts.
For example, the Northeast Fisheries Science Center Milford Laboratory, established in 1931, is located on the shore of Long Island Sound. The facility comprises two laboratory/office buildings and support buildings housing raceway and circular tanks. A 49-foot vessel, the R/V Victor Loosanoff, is also docked at the Laboratory for nearshore research. Present research emphasizes aquaculture and habitat-related work. The aquaculture program includes studies of the culture of fish and shellfish to develop methods suitable for commercial use as well as for stock enhancement and restoration. Nearshore habitats are being studied to determine what characteristics make a habitat suitable for a particular species.
Additionally, the Northwest Fisheries Science Center Environmental and Fisheries Science Division conducts research to improve methods for fisheries restoration and production in conservation hatcheries and in aquaculture. Research focuses on the effects of ocean acidification on shellfish, shellfish safety (harmful algal blooms and pathogens), and native Olympia oyster restoration. Lab research also includes alternative marine fish feeds, larval fish physiology and nutrition.
At the NOAA Beaufort Laboratory, scientists from NOAA Fisheries and National Ocean Service conduct a variety of research including harmful algal blooms, seafloor mapping, and aquaculture.

Regional Activities
Aquaculture is present along our coasts and in our oceans across the nation. Activities and products vary by region so we have regional coordinators supporting these activities and increasing awareness of region-specific issues.
Alaska
The Alaska mariculture industry produces shellfish and aquatic plants along Alaska’s coastline. As of 2016, mariculture activity in Alaska consists of approximately 75 operations, including 65 authorized farms, seven nurseries, and three hatcheries. Most operations are located along the coastline in either Southeast or Southcentral Alaska.

New England/Mid-Atlantic
The New England/Mid-Atlantic region has a commercial marine aquaculture industry supported by a research and technology sector. Landings from marine aquaculture (predominantly Atlantic Salmon and oysters, but also clams, mussels, and other species) totaled approximately $219 million in this region in 2013. This makes aquaculture the third most valuable fishery in the region in terms of economic revenue, behind scallops and American lobster.
Farmed items in New England and the Mid-Atlantic include finfish, shellfish, and sea vegetables grown as food for human consumption. Hatchery-raised species are also used habitat (e.g., oyster) and endangered species (e.g., Atlantic salmon) restoration.

Aquaculture Opportunity Areas
An Aquaculture Opportunity Area is a small, 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 that are environmentally, socially, and economically appropriate for commercial aquaculture.
AOA Frequently Asked Questions

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.
First Regions Selected for Focused Evaluation
NOAA’s Aquaculture Program is already moving forward to meet the mandates set by the White House and recently announced the selection of southern California and the Gulf of Mexico as the first regions for focused evaluation to find AOAs. This selection does not mean the entire regions are opportunity areas. Instead, the selection allows NOAA to deploy our resources to investigate the two regions.
The exact AOA locations will be identified based on best-available science, including data-driven siting analysis using hundreds of types of data on ocean conditions and uses such as existing fishing locations. Stakeholder input is also essential and these AOAs will be shaped through a public process.
NOAA Announces Regions for First Two Aquaculture Opportunity Areas under Executive Order on Seafood
Request for Information and Public Input
NOAA Fisheries invites public comment on two aspects of AOAs during a 60-day public comment period. The agency is requesting information on (1) specific areas to consider for the first two Aquaculture Opportunity Areas within the Gulf of Mexico and waters off Southern California; and (2) other areas NOAA should consider nationally for future Aquaculture Opportunity Areas.
