In the shared waters of Lake Champlain, where Vermont meets Quebec, catfish have been passing a melanoma between themselves for more than a decade — a phenomenon so rare it challenges one of biology's most fundamental assumptions: that cancer is a solitary affliction, born and contained within a single body. Nature has quietly assembled an open-air laboratory, and scientists are beginning to understand what it is trying to teach. The lessons, researchers believe, may reach far beyond the lake, into the deeper mystery of how cancer travels, establishes itself, and endures.

Consumers may face potential restrictions on catfish consumption from Lake Champlain if disease spreads significantly, though current risk appears low. Local fishing communities and tourism dependent on lake recreation could experience disruption if catfish populations decline substantially.
Likely regulatory responses include enhanced monitoring protocols, potential fishing restrictions or advisories, aquaculture biosecurity standards, and increased funding for disease surveillance in freshwater ecosystems. Cross-border coordination between Vermont and Quebec authorities will be necessary.
