Wildlife experts in both California and Oregon report they’re seeing a high number of newly released Chinook salmon sickened and killed by a parasite. The salmon have been found dead at multiple traps in Oregon and California in the Klamath River. The deaths, first reported by Oregon Public Broadcasting, are believed to primarily be due to a parasite called Ceratonova shasta. The parasite, which is linked to the salmon, has reached farther north in the river than ever before following the destruction of four dams near the Oregon-California border. … A recent count from the U.S. Fish and Wildlife Service found that almost half, or 46%, of nearly 700 salmon found in traps have tested positive for C. shasta.
