31,000 Atlantic salmon euthanized at Michigan's Harrietta State Fish Hatchery due to bacterial kidney disease.

31,000 Atlantic salmon were euthanized at Michigan's Harrietta State Fish Hatchery due to bacterial kidney disease (BKD), a disease linked to the decline of Great Lakes Chinook salmon populations in the 1980s. A 28-day antibiotic treatment was attempted, but failed. The Michigan Department of Natural Resources is updating its hatchery system to improve biosecurity and prevent future issues.
