Aquaculture as a whole is the second most valuable fishery in Maine, right behind the iconic lobster. Maine’s cold water is ideal for fish production, and the state’s clean environment and close access to markets has allowed Maine producers to fetch as much as 10 to 15 percent more than competitors. The state’s aquaculture industry also is diversifying. Seaweed and scallops are just a couple of the new areas Maine aqua farmers are exploring. Some companies are even exploring land-based fish farms for salmon and yellowtail, although none have gone commercial yet.
