There is quite a bit of literature now on ranched salmon impacts from not just Alaska but from Asia also. I posted this one a little while ago:
Hard to compare salmon ranching to salmon farming.
First off its a different species of salmon,Atlantic vs a resident,endemic species
Ranching is used to boost wild stocks, if you wanted to ,you could compare Alaska's Ranching to our hatchery production ,the difference being that they are raised in different locations.
You could say our method is more hands off as the fry and smolts are not raised in net pens as they are in ranching.
As for reading all the links, I agree with Tb I dont want to download 4 different links to 40 page documents .If you have something to say, just say it , if we need corrobaration we will ask .
As for the cohen report, how can you use this as evidence for anything , you keep mentioning it like it should have more evidence ,it doesnt.Wouldnt salmon survival be more effected when they are at a young stage.
Anything that would affect them, IE sea lice, would affect them in there early stages not as grown adults.
We need a study on this young stage, I am sure someone has a link to a study on that, it would be an interesting read.
