But even species that appear undaunted by acidification in limited laboratory tests may not be home free.
Walleye pollock, a species that supports one of the largest and most valuable commercial fisheries in the world, appear able to cope with the level of ocean acidification scientists expect over the next century, said Thomas Hurst, a fisheries ecologist at Oregon State University.
But it's not clear whether their prey are as sturdy. Some research suggests that more acidic water shifts the balance of fatty acids in the plankton that pollock consume -- a change that could throw the fish off balance.
"There's still a lot of work to do," Hurst said. "This being one of the nation's fisheries, we can't close the book yet."
Beth Fulton, an expert in marine ecosystem modeling at Australia's Commonwealth Science and Industrial Research Organization, said it is also important to note that the world's fisheries were struggling before ocean acidification was on the horizon.
In many parts of the world, fisheries catches have declined even as demand for fish has ratcheted up.
"We're starting at a baseline where the stocks of the world are already under pressure," Fulton said. "About two-thirds of the world's commercially fished stocks are recovering from past overfishing or are still overfished."
Her work modeling the effect of ocean acidification in southeastern Australia suggests that, if humans continue producing CO2 emissions at the current rate, the region could see a reduction of up to 40 percent of its biodiversity and the average size of many marine species could be cut in half by the end of the century.
"We will still have fisheries -- if we are willing to eat different fish," she said.
