Marine Aquaculture

Marine aquaculture refers to the breeding, rearing, and harvesting of aquatic plants and animals. It can take place in the ocean, or on land in tanks and ponds.

U.S. marine aquaculture produces primarily oysters, clams, mussels, shrimp, salmon, and other marine fish. 

Marine aquaculture creates jobs, supports resilient working waterfronts and coastal communities, and provides new international trade opportunities. As aquaculture has grown to complement our wild fisheries, current and former fishermen are using aquaculture to supplement and support fishing livelihoods.

Farmed seafood products already make up half of the world’s seafood supply, but U.S. production lags behind much of the world, leading to a $16.9 billion seafood deficit in the United States in 2020.

Aquaculture currently accounts for 21 percent of the value of domestic fisheries landings. Doubling current production could result in tens of thousands of jobs in coastal communities.

Marine aquaculture provides a domestic source of economically and environmentally sustainable seafood that complements and supports our wild fisheries production.

The global level of wild-caught fisheries has been relatively steady for more than 20 years, even as the human population continues to grow. Today, the United States imports roughly 70 to 85 percent of the seafood we eat and about half of this imported seafood is farmed.

Global and domestic demand for seafood is poised to grow. Even as we maintain and rebuild our wild fisheries, we cannot meet increasing domestic demand for seafood alone through wild-caught fisheries. Shellfish, finfish, and seaweed farming is a steady source of safe, nutritious, sustainable seafood for consumers in the United States and worldwide.

The United States has a small and vibrant commercial marine aquaculture industry supported by world class research and technology. Aquaculture supplies only about 7 percent of the entire U.S. seafood supply and has a landed value of $1.5 billion. Top marine species grown include salmon, oysters, clams, mussels, and aquatic plants.

Over the past 30 years, we have learned how to manage aquaculture sustainably. The practices and technologies available today are significantly improved over what was available in the industry’s early years. NOAA is committed to monitoring siting and operation of aquaculture facilities to ensure sustainability in production. With our partners and collaborators, we will continue to develop economically and environmentally sustainable marine aquaculture practices in U.S. waters.
