Scientists find 30% of catfish population in Vermont lake affected by a transmissible cancer

A groundbreaking study has unveiled a new transmissible cancer affecting catfish populations, characterized by skin lesions that can spread from one fish to another, which is an unusual occurrence in the animal kingdom. Researchers are now delving into the mechanisms of this disease’s transmission, which has already affected numerous lakes throughout New England and Canada, placing catfish among a rare group of animals susceptible to transmissible cancers.
