DO you really think there is a difference in nutrition in salt water and fresh water salmon. Salmon is very high in EFA,omega 3, and protien....But the difference in the salt water and fresh water...
Often times salt water salmon is faked. It's a much harder catch so counterfieters take advantage of the situation. Now fresh water farm raised salmon should be a safe bet. Plenty of supply and relatively low prices for any incentive in faking it. Know what your salmon should look like before you buy it and know you salmon source.
