Ocean acidification is bad news for shellfish, as it makes it harder for them to form their calcium-based shells. But climate change could also have multiple other impacts that make California bays less hospitable to shelled organisms like oysters, which are a key part of the food web.
Changes to water temperature and chemistry resulting from human-caused climate change could shrink the prime habitat and farming locations for oysters in California bays, according to a new study from the University of California, Davis.
The study, published today in the journal Limnology and Oceanography, shows that changes to dissolved oxygen levels, water temperature, and salinity could have an even greater impact than ocean acidification on oyster growth in estuaries and bays.
