Aquatic Invasive Species

BY DAVID COPPLESTONE, INVASIVE SPECIES RESEARCH TECHNICIAN, OFAH

What are aquatic invasive species?

Zebra MusselAquatic invasive species or AIS are fish, plants, or invertebrates that originate from other parts of the world, and when introduced outside of their native range can cause enormous ecological and economic harm. The zebra mussel, purple loosestrife and the sea lamprey are the most well known examples of AIS, having caused huge changes in the Great Lakes ecosystem as well as cost millions of dollars in control efforts. Invasive species share many common traits, including a high reproductive rate enabling them to build their populations quickly, they also tend to be very adaptable and are able to outcompete native species for food and habitat.

There are over 185 non-native species in the Great Lakes basin, with a new introduction occurring approximately every 8 months. Not all of these introductions have become a problem, but a small percentage as in the case of the zebra mussel have had major impacts and have begun to spread into Ontario’s inland lakes and waterways. Unfortunately once established it is very difficult to control or eradicate invasive species. Thus the best defense we have is prevention and limiting the spread of invasive species from one water body to another.

Best Management Practices for Recreational Boaters and Anglers

Gear such as boats, trailers, motors, fishing tackle, and bait buckets are all capable of transporting aquatic invasive species to new water bodies. Through the use of the following best management practices, anglers and boaters can stop the spread of aquatic invasive species to new water bodies.

You can learn more about aquatic invasive species and obtain educational materials to distribute to your customers through the Invading Species Awareness Program: a partnership initiative of the Ontario Federation of Anglers and Hunters and the Ministry of Natural Resources.
