A pretty decent article at the Tyee on ocean acidification.
I’m not always a big fan of constantly reporting on the bad news… but then… when talking about wild Pacific salmon it’s pretty tough sometimes to report good news.
The ocean acidification discussion is a nasty one. In essence, as we continue to pump carbon into the atmosphere the ocean absorbs it and as more is absorbed, we get acidification… not good for coral reefs, shelled critters, and otherwise. (about the only thing it might be good for… jelly fish)
When baby salmon swim out of their home streams and start migrating up the Pacific coast towards the North Pacific they rely a lot on small shelled critters as one of their main food sources. Slight rises in acidification have drastic consequences on the small shelled critters — and thus a major wild salmon food source at key times of their lives.
There’s another article at the American Fisheries Society: Ocean acidification causes negative effects on fisheries
…highlights how some changes may be coming for some of the starts of one of the only T.V. shows I tend to watch: Deadliest Catch.
…the acidification process in the Arctic, Bering Sea, and Gulf of Alaska is developing faster than expected. Some predictions made for the acid levels said corrosive effects shouldn’t become evident until 2050 or 2100.
As well as the Gulf of Alaska being a pretty key part of most BC wild salmon migrations…

Search the term online and there is a mass of articles dating back several years on this issue.
One key similarity between all the articles…?
Almost all of them suggest that any ‘computer modelling’ on this issue… has been wrong. Various scientists suggest that ocean acidification is occurring at a rate anywhere between 10 time to 50 times faster than any ‘models’ predicted…
Wonder if any of the salmon “scientists” are working these into their computer modelling programs?
