Ocean acidification linked to larval oyster failure
Date:4/11/2012

heric CO2 levels have risen significantly in the past half-century, it means that the water that will be upwelled in the future will become increasingly be more corrosive," Hales said.

The OSU researchers also found that larval oysters showed delayed response to the water chemistry, which may cast new light on other experiments looking at the impacts of acidification on shellfish. In their study, they found that larval oysters raised in water that was acidic, but non-lethal, had significantly less growth in later stages of their life.

"The takeaway message here is that the response to poor water quality isn't always immediate," said Waldbusser. "In some cases, it took until three weeks after fertilization for the impact from the acidic water to become apparent. Short-term experiments of just a few days may not detect the damage."
