What are some cold water fish that are edible?

Some cold water fish that are edible include the Atlantic salmon and blue cod. Typically, both of these fish arrive at market in the form of fillets and steaks.

The Atlantic salmon is often poached, grilled, baked, fried and smoked. This type of salmon covers 25 percent of the world's production of the fish. Very few of these fish are caught in the wild; most of them are raised on fish farms and harvested.

The blue cod finds a home in the Pacific ocean. When purchasing this cod, customers need to refuse any fish that is brown or red, as it's a sign of lack of freshness or incorrect preparation.
