Mollusks' descendants are intended to strengthen commercial shellfish industry
As carbon dioxide levels in the oceans climb, researchers at Nanaimo's Pacific Biological Station are trying to breed oysters that can survive in these new conditions and help prevent a shellfish industry collapse.
For the project, researchers collected 19 families of oysters from Canada, Washington, Chile and the U.K., a variety intended to mirror the composition of oysters sold in the industry. "I screen and find what I would call 'selection candidates' continue our program," Green said."The most important bit for why we do the research is so the shellfish industry in B.C. can take those animals and spawn more and create offspring for B.C. shellfish farms that are now going to have high survival."
After the current three-month phase of the project is completed, Green will be doing a thorough analysis of the oysters, examining ways to further improve them. He will then turn his attention to some of the other climate stressors. The Haida First Nation is working with Pearce and Mackenzie on identifying the reasons for fewer baby razor clams joining adult populations on their beaches in recent years.
