    In the same vein.Why would the Canadians allow the fishfarmers to have huge Atlantic Salmon farms in the pacific.with the industries record of escapees.

    Wasn't it a Scot that populated Patagonia & Tierra Del Fuego with brown trout? John Goodall back in 1935, this intervention of introducing non-native species isn't something new. These destinations are now well renowned for the sea trout fishing & the immense sizes these fish are capable of reaching.

    Absolutely. But having had decades to study the effects of invasive species you'd think that lessons would have been learned since 1935.

    The Romans were at it well before then though.

    Pacific salmon are very adaptable and introduce more successfully. They are superior in just about every way. Better eating too.

    I first came across the pink salmon introductions when I worked for the fish culture research institute in Hungary in 1998. I came across it in our library there which was naturally full of fishy scientific papers.
    They introduced them in the white sea as they wanted a commercial fishery closer to Moscow (or habitation in Russia!) As pink salmon is a high commercial sector for them. they also released king crab at roughly the same time. If i remember rightly, pink salmon spawn lower down a system, often just above the tidal zone, so hopefully they won't share spawning zone as Atlantic's. But I have seen them about 200 miles above the tide on the skeena system in Canada, their rivers are a lot bigger than ours so who knows what will happen.
    They like shallow water so they can be easy to spot off gravel bars etc, so keep an eye out.
    Sorry, I types this on my phone so may seem disjointed!

    Brave new world, courtesy of the Russians. How could that go wrong?

    Compared with other countries, a few pacific salmon shouldn't be as destructive as the silver carp & snakehead fish which decimate natural fish stocks, these, like Atlantic salmon, rarely feed in freshwater & will no doubt, provide excellent sport for migratory anglers. After all, carp, zander & other species were introduced and provide the same angling challenges for coarse anglers. Rainbow trout in stillwaters have had their fare share of escapees & even breed in rivers up around the Derbyshire Wye.

    Thanks Taffy for posting the news report.

    I'm on the Tweed and Tyne this week, it's looking quite dry so even a Pacific might be welcome

    When our Atlantic salmon stocks are under such pressure, when the stock levels in the majority of our rivers are borderline self sustaining or below, I doubt you'll get much support for that point of view. You say 'shouldn't' but the difficulty is that nobody knows what impact their presence will have upon native stocks.

    Did Eric Verspoor not say he wouldn't worry as these obvious hatchery fish would enter a destructive vortex and die out in a few generations? I'm sure that was what he said about Atlantics, perhaps he could get funding for a genetic study!!
