Stay tuned for Fact Sheets for all of the aquatic invasive species legislated by the Fisheries Act (Alberta) to be added soon.

“Invasive species can threaten aquatic ecosystems, occupying habitats or out-competing native species. These invasive species may show rapid population growth in the absence of natural predators and may soon become established to the point where eradication is impossible. Aquatic invasive species can be introduced in several ways: either naturally as larvae or as fragments drifting in water currents; or through human activities, attached to boat hulls or in ballast waters for instance. These various invaders pose threats to ecology and the economy. While regulators, scientists, and members of the aquaculture and fishing industries are the most concerned, the problem affects everyone using our waters: recreational boaters, fishers and harvesters, cottage owners, divers, etc. The best approach for protecting our ecosystems from these invaders is to keep them out in the first place, and to do this, everybody’s cooperation is essential.” – Fisheries Canada.
