Didymo Algae


While Didymo Algae is no longer considered alien,
its proliferation remains detrimental

An article published in the Canadian Journal of Fisheries and Aquatic Sciences reports a recent study, which demonstrated that Didymo Algae already existed in the rivière Matapédia watershed. As such, while it is no longer deemed an alien species, its proliferation is a new phenomenon in Eastern Canada.

Consequently, information and documents posted on this page will be updated shortly.

Aquatic invasive species - Don't give a ride to intruders (PDF file, 717 Ko)

In 2006, a new aquatic invasive species called Didymosphenia geminata appeared in Rivière Matapédia. This alga, also known as didymo, is not toxic. It is not harmful to human health and does not render water unfit for consumption. However, once it has invaded a water body, it can modify natural habitat and species composition of the various algae and invertebrates living on the bottoms of rivers and lakes. In this section, you will find information that can be used to raise the awareness of persons who fish and canoe our waters so that they can take the necessary precautions and avoid spreading invasive algae.
