In Brazil, Nile tilapia ("Oreochromis niloticus") fish skin applied as a bandage is being used in a new clinical trial to treat burn injuries. In the United States, tilapia skin has been used to successfully treat third-degree wounds to the paws of two black bears caught in California's Thomas wildfire, and also to treat burns on the paws of a black bear from California's Carr wildfire. Nile tilapia skin has completed a phase III clinical trial for burn treatment, but no results have been posted as of November 2020.
