Canadian filmmakers have filmed coaster brook trout spawning on the outer islands of the Lake Superior National Marine Conservation Area. It is believed to be the first footage of the event.

While most Coaster Brook Trout spawn in rivers, researchers and Indigenous knowledge holders have long suggested that some may also spawn among Lake Superior's remote outer islands. Witness what we believe to be the first documented footage! @ParksCanada
