Some farmed salmon slip into Alaska streams
At fish farms hundreds of miles away, along the coasts of British Columbia and Washington state, Atlantic salmon raised in ocean pens are a lucrative cash crop. But some have escaped and made their way into Alaska streams, where they are unwanted invaders.
So far, Atlantic salmon don’t seem to have established new populations here. But Doug Mecum, the director of Alaska Department of Fish and Game’s Commercial Fisheries Division, says the fact that some farmed salmon have been found breeding successfully in creeks in Washington and British Columbia is cause for concern.
“We have observed that they actually can successfully reproduce, so that’s one of the reasons why we’re concerned,” says Mecum.
