Warming rivers in US West killing fish, imperiling industry


              In this photo provided by the California Department of Fish and Wildlife, juvenile Chinook salmon flow through a tube toward a hatchery truck at the Iron Gate Fish Hatchery, Siskiyou County, Calif., before their relocation on July 7, 2021. Recently California fish and wildlife officials decided not to release more than 1 million hatchery-raised baby chinook salmon into the wild, and instead drove them to several hatcheries that could host them until Klamath River conditions improve.
