Ruffe: A New Threat to our Fisheries

The ruffe (pronounced ruff), is a small but aggressive fish species native to Eurasia. It was introduced into Lake Superior in the mid-1980s in the ballast water of an ocean-going vessel.

Because the ruffe matures quickly, has a high reproductive capacity, and adapts to a wide variety of environments, it is considered a serious threat to commercial and sport fishing. It also has the potential to seriously disrupt the delicate predator/prey balance vital to sustaining a healthy fishery.
