"Wild salmon count is currently at an all-time low due to the collapse of the Sacramento River Chinook run, which is usually one of the most productive on the Pacific Coast, providing the bulk of the salmon caught by sport and commercial trollers off California and Oregon.

But only about 90,000 adult Chinook returned to the Central Valley last fall - the second lowest number on record and well below the number needed to maintain a healthy fishery. That number is projected to fall to a record low of 58,000 this year. By contrast, 775,000 adults were counted in the Sacramento River and its tributaries as recently as 2002."
