To Breed An Oyster
In the ocean, climate change involves more than just warming temperatures. Water levels are shifting, and ocean chemistry is changing. Changes to ocean salinity caused by shifting amounts of freshwater could have big effects on the health of oysters, who need a certain range of saltiness in the water to be happy.
As part of her doctoral work at Louisiana State University, researcher Joanna Griffiths bred hundreds of families of oysters, looking for clues to what makes an oyster more able to endure salinity changes. She found that there is a genetic component to an oyster’s salinity resilience.
Griffiths joins SciFri’s Charles Bergquist to talk about the work, and the challenges of conducting a laboratory oyster breeding program—in which it’s difficult convince an oyster that it’s time for romance, and often even hard to discern the sex of the oysters involved.
Joanna Griffiths is a postdoctoral student at the University of California, Davis in Davis, California.
