Acidification, predators pose double threat to oysters
Date:1/15/2014

The once-booming, now struggling Olympia oyster native to the West Coast could face a double threat from ocean acidification and invasive predators, according to new research from the University of California, Davis' Bodega Marine Laboratory. The work is published Jan. 15 in the journal Proceedings of the Royal Society B.

Invasive snails ate 20 percent more juvenile oysters when both oysters and snails were raised under ocean conditions forecast for the end of this century, the researchers found. The results highlight the dangers of multiple stressors on ecosystems, said Eric Sanford, professor of evolution and ecology at UC Davis and first author on the study.

"You might decide to go to work if you had a toothache. But what if you had a toothache, the flu, and a broken leg? At some point, multiple stressors will cause natural systems to break down," he said.

Native Olympia oysters were once so common in San Francisco Bay that they were a cheap food during the Gold Rush, commemorated in Hangtown Fry, an omelet of eggs, bacon and oysters. The population collapsed from overfishing in the late 1800s and has never recovered.

Atlantic oysters imported to the West Coast brought predatory snails such as the Atlantic oyster drill, which uses acid and a rasping tongue to drill holes in oyster shells.

Scientists have become increasingly concerned about the effects of climate change on ocean chemistry. As heat-trapping carbon dioxide builds up in the atmosphere, some of the gas dissolves in the oceans, causing a steady rise in the overall acidity of the oceans. An interdisciplinary team of researchers based at UC Davis' Bodega Marine Laboratory is looking into the oceans' future by raising animals in seawater with raised levels of dissolved carbon dioxide. In earlier work, they found that oysters raised under conditions predicted for the end of this century are smaller than present-day animals.
