No surprises there.
Also not surprising to me is the CBC article in which the dept of Aquaculture minister dismisses accumulating evidence suggesting that aquaculture can be harmful to wild stocks. It is criminal how short-sighted our government policies are when it comes to industry over ecosystem. :mad:

Honestly, I don't think it will be much longer before wild Atlantics are essentially extinct in much of Atlantic Canada. Many of the remaining populations are hanging on by their finger nails, and many if not most are not meeting the minimum escapement numbers. Time to cut down some more forests in the watersheds, dig a few more mines in the river headwaters, and open a few more aquaculture facilities in the estuaries. :Eyecrazy:

While they are at it they can continue to ignore live release angling as well and keep killing the ones that have made it back to the rivers for spawning. Might as well eat the salmon while they are still here; tartar sauce anyone

Thank's for posting the URL's . Interesting stuff !! Fred Worisky will be updating his"migration pattern" report in the June FQSA "Saumons " and ,I believe in the ASF Journal . An interesting part of which , was found that the Grilse migrated to the sea around NFLD .The sea temp in Aug and Sept last yr was -1C. .Salmon DIE at -.8C !!!.This would explain the dearth of Grilse in '07 and doesn't bode well for '09 !
Cheers

Outlawing fish farms in areas where indigenous salmon live, migrate or are otherwise negatively influenced is a no-brainer.

In fact since it's such a huge business now maybe the companies should ante up and conduct more responsible practices instead of being hungry for the billions they make.

A capitalist would point out that this kind of law would tilt the scale toward Argentina and other parts of the world where they raise salmon now, and hurt the North American and European fish farmer - but unless they can mitigate the risks they will just have to find another line of work.

Alaska outlawed fish farming and coincidentally (or not) have the biggest salmon runs on Earth.
