California

Coho Salmon – Oncorhynchus kisutch

  • Status – Endangered
  • Estimated numbers – The Coho salmon population in the Southern Oregon and Northern California region has declined from an estimated 150,000 to 400,000 spawning fish in the 1940s to fewer than 10,000 adults today
  • Population trend – Decreasing
  • Location – The traditional range of the Coho salmon runs along both sides of the North Pacific Ocean, from Hokkaidō, Japan and eastern Russia, around the Bering Sea to mainland Alaska, and south to Monterey Bay, California.
  • Why are they under threat – These reductions are due to natural and man-made changes, including short-term atmospheric trends (such as El Niño, which causes extremes in annual rainfall on the northern California coast), predation by the California sea lion and Pacific harbor seal, and commercial timber harvesting
