MARK BITTMAN: What oysters tell us about ocean acidification

July 21, 2015 — MARK BITTMAN — This is kind of the good news/bad news department, as so many things are: The good news is that terrific oysters are being farmed in several locations in California; the bad news is that ocean acidification — the absorption of carbon dioxide into the sea, a direct result of high levels of carbon in the atmosphere — is a direct threat to that industry.

I saw both when I visited Hog Island Oyster Co. in Marshall, an operation north of San Francisco on Tomales Bay. (Actually, I’ve eaten at and of Hog Island dozens of times, and even shot video there for a PBS series more than 10 years ago.)

Lessons for Alaska: Oregon Shellfish Hatchery Tackles Ocean Acidification

July 13, 2015 — A recent NOAA study pegged 2040 as the date for the potential end of Alaskan shellfish hatcheries. That is, unless serious mitigation efforts are put in place to combat ocean acidification. Last week we reported on the research, done at the Alutiiq Pride Shellfish Hatchery in Seward. Now, we’ll take a look at what a hatchery on the Oregon coast is doing to deal with these harmful changes in ocean chemistry.

The Whiskey Creek Shellfish Hatchery is located in the small town of Tillamook, Oregon.

“This hatchery was started by Lee Hanson,” says Sue Cudd, who owns the hatchery now. “It was really the first shellfish hatchery that was commercial in operation. It started in 1978.”

She studied biology in school, worked for an oyster company for a while, and then came on with Lee Hanson to learn about the hatchery world. From the 1970s until 2006, there were natural ups and downs, but overall, things ran relatively smoothly.

“Then all of a sudden, in about 2006, we started seeing some pretty major problems. Then from the end of 2007 to the end of 2008, we couldn’t produce larvae anymore,” says Cudd.

For a year and a half, they tried to produce. Even when they did manage to get some larvae, they wouldn’t survive and develop. It was a financial nightmare for the business.

“We lose money really fast because the production cost is the same without having any production. So, it was tough,” says Cudd. “We got help from some customers. The oyster growers association [helped] and one of our state senators got us some community development money, so we had time to be able to try to solve this problem. Without that, I don’t know what would have happened because we just lost money so fast.”
