This is a wonderful article for all salmon fans. When they tested "wild salmon" from 8 restaurants in New York, only one turned out to be genuinely wild. They are able to tell this by testing the astaxanthin pigment which makes salmon pink. Farm raised salmon have to be fed an artificial form of astaxanthin which is distinguishable from the natural form.
Just to be clear, this is NOT a wild caught salmon.Posted by Randy Olson at April 15, 2005 05:42 PM
