I gotta laugh when they say they don't want to label this fish if it ever shows up in stores for what it is. I'm with you guys on this, there is too much risk involved here. And if this stuff starts appearing at Walmart, then it should be clearly labeled for what it is.
On a side note, I lived on the Pacific Northwest for 20 years, there are many Atlantic salmon farming operations going on there, I can remember one mass escape in Puget Sound where 60,000 3-5 lb Atlantics made a breakout (I think they tunneled under the fence). I caught one in the Skykomish river while steelhead fishing and they were caught all over in area rivers and in the Sound. Then they disappeared, there never were any proven reports of Atlantics successfully spawning in the wild from that escape or any escapes in the PNW. Not that it couldn't happen, but it's very unlikely.
On an even further side note, I also used to live in New England, used to travel up to the White river in Vermont (It's a beautiful river to fish if you're ever up that way, rainbows and browns and it also has a population of under fished and under appreciated smallies). But there's an Atlantic salmon hatchery on the upper White that has been in existence since 1970, they are trying to reestablish Atlantics in the White and other rivers in New England, I think there best return was a couple of hundered fish and that was 20 years back, Atlantics are a very difficult fish to reestablish even in their (altered) native habitat. Personally I think they should shut down the effort, but it's not a total loss, there has been and are continuing habitat projects and passage work done in the name of Atlantics that have benefited other fish species.
