Danger in the Great Lakes: The Asian Carp

The Asian carp is an invasive species that poses a great threat to the native species in the Great Lakes. Although they were first introduced to control algae in farms, they managed to escape to the rivers. They grow very quickly and are not prey for any of the natural predators. Soon, Ontario may have a very serious carp problem!

Meet the Invaders

There are 4 main types of Asian carp present in U.S rivers that lead to the Great Lakes.

Bighead Carp
Silver Carp
Black Carp
Grass Carp

Which species poses the biggest threat at this moment to the Great Lakes?

Did you know?

Grass carp feed on huge amounts of aquatic plants needed for other species and can grow up to 5 ft long!

Confused with Carp?

Identifying Asian Carp can be very difficut since they resemble many native Ontario species. The best way to avoid confusing them with common look-a-likes is to look for distinct markings/features.

Plan of Action: Keep the Carp Out!

Biological Control - Predators

Manipulate natural enemies to control the population and growth of carps in waterways. A silly example would be sharks!

Chemical Control - Pesticides

Use pesticides and other chemical solutions to eliminate carps from rivers.

Manual Control - Netting

Destroy the invasive species by hand, which involves netting and removal of carps via fishing.
