Transmissible cancer detected in 30% of catfish across Vermont lake
A new study has identified a contagious form of cancer spreading among catfish populations in a Vermont lake. The disease manifests as skin lesions that can pass directly from one fish to another, a phenomenon considered highly rare in the animal kingdom. The infection has already been detected across multiple lakes in New England and Canada, suggesting a wider regional spread. Researchers are currently investigating how the disease transmits between fish. The findings place catfish among a small group of animals known to be vulnerable to transmissible cancers.
