Ocean Acidification Linked to Mass Death of Northwest Oysters

Posted by on Thu, Apr 12, 2012 at 9:19 AM

Today in alarming:

Researchers said Wednesday they can definitively show that ocean acidification is at least partly responsible for massive oyster die-offs [over the last eight years] at the hatchery in Netarts Bay, Ore.

It's the first concrete finding in North America that carbon dioxide being taken up by the oceans already is helping kill marine species.

Eat 'em while we got 'em.

@14 I come from a long line of hillbillys who hunt and fish and everything has dwindled? chinese carp are as close as Congress has come to environmental solutions?…

My family has had property in the San Juan Islands since 1952, and we have noticed a precipitous decline in oyster production on our beach in the last 20 years. I know the plural of anecdote does not equal data, and I'm not a marine biologist, but I'll tell you I'm inclined to believe that this is a problem.

@2 is right.

@9 is correct. But we knew that.

Most "wild" oysters are actually Japanese imports grown in hatcheries like this. The numbers of true native oysters, Olympia oysters, have been dwindling for years, as I understand it, because it's more profitable to grow the Japanese varieties (Kumamotos, Pacifics, etc.), which are easier to spawn, and larger; although they've been making a comeback in some places.

This article doesn't say what kind of oysters are dying, though I suspect it's all varieties. One of the biggest Olympia oyster breeding projects is also in Netarts Bay, but this is about the hatchery, which I believe grows all kinds from the description in the article.

It's interesting that we're hearing about this from the Oregon coast, which is where the reports of unusual deep water upwelling have also come from, in addition to the wind events they're talking about, and from Willapa Bay, which is close to Oregon. Have they noticed this die-off in Puget Sound? The article doesn't say.

Cold, acidic deep water upwelling is very obviously a climate-change event, and scares me quite a bit.

It would be really interesting if climate change drives growth in Olympia oysters' comeback. The little buggers have already proven they like polluted water.

Acid rain was know about since "?" we are way past the organic natural of the 1800's. As for America we are not a Nation of science and education. as for the rest of the world they use the ocean to dump radio active drums and all kinds of crap.

The coast guard would rather sink ships then tow them to port and chop them up.

It makes me sad that even in the face of real-world concrete evidence, all you get is denial, denial, denial.

I'd prefer the headline "Ocean Acidification Link to Mass Death of Climate Change Deniers"

What's depressing about this regrettable (and widely reported) phenomenon is the virulence of the comments by climate-change deniers.

Fuck. They can't make their shells.
