Another point that has to be considered is the reference compares farmed salmon (Atlantic Salmon) to wild salmon without regard to the species of wild salmon. This is a common approach of both the opponents and the supporters of salmon farming. I suspect if one were to construct a table comparing the nutritional benefits of eating wild pink salmon to those of eating wild chinook there might be even more differences then wild and farm reared. At the end of the reference where the author mentions pollutants he makes the same mistake. If you read the actual studies wild chinook are as toxic if not more so than west coast farmed reared salmon.
