Hundreds of thousands of salmon released in Northern California river die in ‘large mortality’ event
As many as hundreds of thousands of fall-run Chinook salmon died early last week due to suspected gas bubble disease. The fish were released into the 257-mile-long Klamath River near the California-Oregon border following November’s historic dam removal at the site, which was intended to help the stream flow freely again and bolster the habitat for the protected species. Still, the CDFW said those conditions, while unfortunate, were anticipated, and that its hatchery has over three million more salmon it plans to release later this month, downstream from the dam and tunnel. Juvenile fish like salmon fry can have high mortality rates due to predators, lack of food or disease, and the CDFW’s planned release will include fish in later stages of the species’ life cycle, specifically smolts and yearlings. more, >>click to read<< 09:28
Why California’s most productive salmon hatchery is millions of fish short
California’s most productive salmon hatchery has 6 million fewer fish this year, another sign the state’s drought woes linger despite last winter’s record rainfall. The federal Coleman National Fish Hatchery tries to produce about 12 million fall-run Chinook salmon for release each spring into Battle Creek, a Sacramento River tributary south of Redding. This spring, the Coleman hatchery will only have half as many young salmon to release. click here to read the story08:16
