Pinto abalone was once plentiful in Washington’s waters but has declined by a shocking 97% since the early 1990s. What is causing this massive decline in population? A new Northwest Climate Adaptation Science Center-supported study, led by former NW CASC Research Fellow Eileen Bates and other researchers from University of Washington, Puget Sound Restoration Fund, and Washington Department of Fish & Wildlife explores how climate warming and ocean acidification are threatening hatchery-raised abalone in the early life stages. The findings of this research are actively helping to improve hatchery practices and locate climate-resilient restoration sites.
