Hi Rat; Nice try but quoting from your article: "The waters were not manipulated and differences in the chemistry were accounted for by shallow and deep water intake pipes at the hatchery."
We already knew that deep ocean water has a lot of CO2, and that upwellings can be tough on oysters:
CLIMATE: Wind-driven Ocean Upwelling Kills Oysters
Researchers indicated in a recent article (TNT, 4-13) that huge oyster die-offs are occurring along the Northwest coast, but only when wind-driven upwelling events bring deep and naturally corrosive water containing more dissolved carbon dioxide up to the ocean surface.

In other words, it's not man's CO2 on the surface that damages oysters, it's CO2 from the deep. And the winds have been switching directions on the Pacific for thousands of years. It's the "Pacific Decadal Oscillation".
The Willapa Bay oyster reserves in Washington state: fishery collapse, creating a sustainable replacement, and the potential for habitat conservation and restoration.
Seasonal recruitment and survival of Pacific oysters to shell strings averaged 8.3 recruits per shell, although the range was high (0 90 recruits per shell), and commercial sets (>3 recruits per shell) occurred in more than half (44 of 73) the years monitored (Fig. 4). More consistently high recruitment occurred from the late 1930s through about 1959, after which recruitment was low through 1981 and then increased and was generally better through 2005. The period of low recruitment roughly brackets a period of low harvest from the reserves that began in 1969 and ended in 1979 (Fig. 3) and an extended period of low values of the Pacific decadal oscillation, a climate index for the northeast Pacific (Hare & Mantua 2000). Although records are incomplete, recruitment of Pacific oysters in Willapa Bay from 2005 to 2010 has also been minimal, but it is too soon to know whether this represents another shift in the long-term pattern.

As usual, the basic problem with the research is that it ignores the natural long term oscillations in the climate. Oysters have had difficulties making new oysters for thousands of years. This is not news, it's just a diversion from the failing "global warming is gonna kill us all" theme.
And I think it's a good diversion. The reason why CAGW failed is that it got too many people working on it and couldn't survive the attention. The "ocean acidification" BS could live on for years, unexamined because it doesn't matter, like the "honeybee crisis".
As the sea ice grows back and temperatures refuse to keep rising, you'll be forced to post articles like the above, LOL.
