According to the executive director of the the Pacific Fishery Managment Council, Donald McIsaac, the West Coast is facing "what appears to be an unprecedented collapse in the abundance of adult California Central Valley... fall chinook salmon stocks."
Blogger OneMuleTeam says: What really has fisheries managers (and me) worried is that only about 2,000 2-year-old juvenile chinooks — which are used to predict returns of adult spawners in the coming season — returned to the Central Valley last year, by far the lowest number recorded. On average, about 40,000 juveniles, or “jacks,” return each year. I was no math major but I know that 1/20th of average = not good.
