Scientists have now found evidence the 'voracious' fish are spawning in Ontario's Thames River.

Flathead catfish "get very large and they eat a lot of fishes, so they're likely to have a substantial negative impact if we do not do anything to control their populations," Mandrak said.CBC News contacted both the Upper Thames River Conservation Authority and Lower Thames River Conservation Authority.
