Aquaculture in Alaska

Shellfish farming and salmon ranching

Private non-profit (PNP) hatcheries, primarily owned by commercial salmon fishermen, support the fishery with releases of approximately 1.5 billion salmon smolt each year. In recent years, these smolt releases have contributed nearly 30 million fish annually to the commercial fishery.

New supplies of salmon from worldwide farming and strong wild runs in Alaska have reduced the market price, causing economic distress for the Alaska salmon fishery and PNP hatchery income.

How the Marine Advisory Program assists

The Marine Advisory Program is involved in PNP hatcheries in efforts to facilitate sharing of resources and information, and conduct a coordinated applied research program.

State law restricts aquatic farming to seaweeds and shellfish. Started as a fledging industry in the late 1970s, shellfish farming has been revitalized with passage of the Alaska Aquatic Farm Act in 1988. Since 1988, the aquatic farming industry has grown from a single farmer to over 60 farms. In 2002, the State of Alaska passed legislation intended to increase the number of shellfish farms and the variety of species available for farming.

The Marine Advisory Program's aquaculture mission is to provide support for the rapidly expanding shellfish farming industry and provide technical assistance to the salmon ranching effort.

Aquaculture resources

The Sea Grant network has established a National Seaweed Hub to serve as a science-based, non-advocacy resource for the domestic seaweed and seaweed aquaculture industry. This collaboration provides a framework to share information, address challenges, identify needs, and find opportunities in this emerging industry.

We are hosting the Access to Capital for Mariculture Businesses webinar series in collaboration with the Kodiak Archipelago Leadership Institute to share information about sources of capital for starting and expanding mariculture operations. Visit the site for information, dates, registration, and recordings.

We have compiled a directory of farms and retailers in Alaska that sell or ship Alaska-grown seaweed or shellfish products. Alaska seafood, whether grown or wild harvest, comes from pristine waters and is prized as some of the highest quality seafood in the world.
