Commercial landings, ex-vessel value and price per pound from the California Department of Fish and Wildlife, 1980–2025.
Ocean conditions from the Relative Oceanic Niño Index (RONI), NOAA.
Expert climate vulnerability scores from the California state CVA (Frawley et al. 2025, PLOS Climate), covering 34 state-managed species, 19 of which appear in this catch record.
A correlation points to a relationship worth studying, not a cause. Catch records also carry fishing effort, quota changes and market shifts that no ocean index attempts to explain.
