Artificial Propagation
Anadromous fish hatcheries have existed in California since establishment of the
McCloud River hatchery in 1872. There are nine state hatcheries: the Iron Gate
(Klamath River), Mad River, Trinity (Trinity River), Feather (Feather River), Warm
Springs (Russian River), Nimbus (American River), Mokelumne (Mokulumne River),
and Merced (Merced River). The California Department of Fish and Game (CDFG) also
manages artificial production programs on the Noyo and Eel rivers. The Coleman
National Fish Hatchery, located on Battle Creek in the upper Sacramento River, is a
federal hatchery operated by the USFWS. The USFWS also operates an artificial
propagation program for Sacramento River winter run Chinook.
Of these, the Feather River, Nimbus, Mokelumne, and Merced River facilities comprise
the Central Valley Hatcheries. Over the last ten years, the Central Valley Hatcheries
have released over 30 million young salmon. State and the federal (Coleman hatchery)
hatcheries work together to meet overall goals. State hatcheries are expected to release
18.6 million smolts in 2008 and Coleman is aiming for more than 12 million. There has
been no significant change in hatchery practices over the year that would adversely affect
the current year class of fish. A new program marking 25% of the 32 million Sacramento
Fall-run Chinook smolts may provide data on hatchery fish contributions to the fisheries
in the near future.
Commercial and Recreational Fishing
The region is home to many commercial fisheries. The largest in terms of total landings
in 2006 were northern anchovy, Pacific sardine, Chinook salmon, sablefish, Dover sole,
Pacific whiting, squid, red sea urchin, and Dungeness crab (CDFG 2007). Red abalone is
also harvested. The commercial landings report does not include information on bycatch
of listed salmonids (CDFG 2007). The first salmon cannery established along the west
coast was located in the Sacramento River watershed in 1864. However, this cannery
only operated for about two years because the sediment from hydraulic mining decimated
the salmon runs in the basin (NRC 1996).
