Overview

Alaskan aquaculture
Aquaculture
Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the...

, plants, and other species that all play an important role in the aquaculture process. Commercial salmon and herring fisheries dominate Alaskan harvesting and production and harvesting sights are located on the coast line throughout the state, producing an average of 750 million pounds each year. Commercial shellfish fisheries also greatly contribute to annual statistics and at its high point 400 million pounds of shellfish have been produced in one year.

Salmon

 to Alaskan waters provide one of the most important industries in Alaska. Beginning in the 1880s, commercial salmon fishing has become a dominant area of Alaskan aquaculture. Over the course of four years the average salmon harvest by commercial fishermen was approximately 157 million fish or 742 million pounds and averaged an annual value of over $230 million. Many inhabitants of Alaska greatly rely on the salmon harvest each year for income and cultural purposes. Major salmon fisheries in Alaska are located in the Yukon, Bristol Bay, Southeast/Yakutat, Cook Inlet, Chignik/Kodiak, Copper River, and Prince William Sound areas..

Herring

Crabs

Crabs are a dominant and famous source of aquaculture found in Alaska, particularly the king crab

King crabs, also called stone crabs, are a superfamily of crab-like decapod crustaceans chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food, the most common being the red king crab, Paralithodes camtschaticus.King...

Red king crabs dominate over the other species in commercial harvesting and are most commonly found in the Bristol Bay area and less commonly but still found in the Southeast, Norton Sound, and Adak areas. Other important crabs harvested in Alaskan areas include the Tanner crab, snow crab, and Dungeness crab.
