California Trout’s landmark report on the state of California’s trout, salmon & steelhead populations paints a troubling picture of the state’s native salmonids.

SOS: California's Native Fish in Crisis cover

SOS: California’s Native Fish Crisis was written and researched by Dr. Peter Moyle, UC Davis professor and renowned expert on California’s water systems and the fish that inhabit them.

The report’s findings indicate the state’s native salmonids are in unprecedented decline and with many teetering towards the brink of extinction – an alarm bell that signals the deteriorating health of the state’s rivers and streams (that also provide drinking water to millions of Californians).

All indications show that California’s native fish are in crisis:

  • If present trends continue, 65% of native salmon, steelhead, and trout species will be extinct this century
  • 65% of the species headed towards extinction are found only in California
  • Of the state’s 22 anadromous fish species (which spawn in freshwater and live most of their adult lives in the ocean), 59% are in danger of extinction
  • Of the state’s 9 living native inland fish, 78% are in danger of extinction
