Aquatic Invasive Species

What are Aquatic Invasive Species?

Aquatic invasive species are fish, animal and plant species that have been introduced into an aquatic ecosystem (ocean, lake, river or stream) where they have not been found historically. They establish themselves in our coastal or inland waters where, in the absence of their natural predators, the most aggressive of them spread rapidly. This can, and often does, result in harmful consequences for the native species. Introductions of aquatic invasive species can result in damage to sensitive ecosystems, as well as fisheries, aquaculture, municipal infrastructure, tourism and other important industries.

Occurrence of aquatic invasive species is on the rise with increases in global trade. As of 2010, five marine aquatic invasive species have been identified in Newfoundland and Labrador waters.  These pages can help you recognize, remove, and report aquatic invasive species in Newfoundland and Labrador.
