Biologists Trevor Kennedy, bottom right, and Roxanne Kessler, top center, release smolts, younger versions of chinook salmon, onto holding pens with the help of boat captain Doug Wagoner, bottom left, in Vallejo, Calif., Thursday, June 4, 2009. Biologists from the Fishery Foundation of California were releasing 550,000 smolts into the San Francisco Bay Thursday in hopes of restoring commercial and recreational fishing. Federal fisheries regulators released a wide-ranging plan Thursday to help the struggling chinook salmon, saying state and federal water projects have contributed to the decline of the fish and other endangered species in the Central Valley. The National Marine Fisheries Service recommends a new water temperature management plan for the upper Sacramento River and Shasta Reservoir and opening dams to allow for better salmon migration, among other things, in the new report.
