Rainbow, brown, and brook trout

Rainbow, brown, and brook trout (Oncorhynchus mykiss, Salmo trutta, and Salvelinus fontinalis, respectively) are cold water fish which require well oxygenated water below 65F. They are cultured commercially in many northeastern states. Pennsylvania and New York are the leading producers in the region.

Most trout are grown in flow-through systems; although some culturists currently reuse their water and a few use cages or net pens. Rainbow trout are marketed for stocking and as food fish. Brown and brook trout are stocked for recreational fishing; some are also sold as food fish.

Atlantic salmon

Atlantic salmon (Salmo salar) are native to the eastern United States and better suited to aquaculture conditions than their Pacific coast relatives. The Atlantic salmon has become an important aquaculture species. Most commercial aquaculture in the Northeast is located in New England, particularly Maine.

Atlantic salmon are released as smolts in streams to enhance natural populations and cultured in cages or net pens placed in areas with substantial flushing. Smolts may be produced in freshwater hatcheries or purchased
