The U.S. West Coast’s native Olympia oysters face a greater threat from invasive predatory snails as climate change raises the acidity of oceans, research by the University of California, Davis found.
Predatory snails ate 20 percent more young bivalves when both species were raised in ocean conditions forecast for the end of the century, according to a university report published in the journal Proceedings of the Royal Society B. Oysters raised by the researchers under the high carbon dioxide conditions forecast for 2100 stayed smaller, while the snails were not affected and as a result ate more shellfish.
“It’s like if you go out for tacos,” Eric Sanford, professor of evolution and ecology at UC Davis and lead author of the study, was cited as saying. “If the tacos are smaller, you’re going to eat more of them.”
Olympia oysters were once so common in San Francisco Bay that they were a cheap food during the California Gold Rush, before the population collapsed from overfishing in the late 1800s, never to recover, the university wrote.

Inside the Industry

The anti-mining group Salmon Beyond Borders expressed disappointment and dismay last week at Alaska Governor Bill Walker’s announcement that he has signed a Memorandum of Understanding with B.C. Premier Christy Clark.

This came just days after his administration asked members of his newly-formed Transboundary Rivers Citizens Advisory Work Group to provide comment on a Draft Statement of Cooperation associated with Transboundary mining.


NMFS recently released a draft action plan for fish discard and release mortality science, creating a list of actions that they hope can better inform fisheries.

We know that fishermen have to deal with bycatch by discarding or releasing unwanted catch overboard, but there is a data gap regarding how those fish survive.
