Researchers tracking whether contagious catfish cancer in Quebec has spread to N.B.
Scientists say DNA results from New Brunswick catfish could confirm the first known transmissible melanoma in a freshwater fish population.
- Researchers are investigating whether a rare, transmissible catfish skin cancer discovered in Lake Memphremagog along the Quebec-Vermont border has reached New Brunswick, following reports of similar lesions on local fish.
- University of Vermont scientists determined the melanoma is the fourth known naturally occurring transmissible cancer in the animal kingdom, a development researchers called a "puzzling biological phenomenon."
- In May, Cambridge researcher Zoe Clarke collected samples with fisherman Scott Young, and she is now awaiting results from the Hubbard Center for Genome Studies in New Hampshire.
- While experts confirm the cancer poses no risk to humans, the U.S. Fish and Wildlife Service advises against eating fish with obvious lesions or growths.
- Clarke plans to return to New Brunswick next year to sample fish throughout the Saint John River, aiming to solve the mystery of how the cancer is spreading through freshwater ecosystems.
