April 24, 2025 — A new climate vulnerability study paints a sobering picture for California’s fishing industry, highlighting serious threats to the state’s most iconic and economically critical species, including Dungeness crab, red abalone, and Pacific herring.
The study, first reported by NBC Bay Area’s Joe Rosato Jr., resulted from a collaboration between federal and state scientists and researchers from UC Santa Cruz and UC Davis. It evaluated 34 aquatic species for their sensitivity to projected climate change impacts, including warming seas, ocean acidification, and shifting upwelling patterns that drive productivity along the coast.
“The most striking thing that we found is among the species that were ranked as the most highly vulnerable happened to also be some of California’s economically valuable and culturally important species,” said Mikeala Provost, assistant professor of fisheries ecology at UC Davis and a co-author of the study.
