  1. An innovative detection tool: Environmental DNA or eDNA

    Environmental DNA is an innovative method used to detect different species in the aquatic environment. Similar to barcodes used to identify items at the grocery store, eDNA allows biologists to identify different aquatic species through their unique genetic fingerprint. By releasing cells and other biological material such as skin particles, mucus, urine and feces into the environment, scientists are able to identify a species with its eDNA.

  2. State of the St. Lawrence 2019: A slight improvement, but a fragile balance

    The latest version of the Overview of the State of the St. Lawrence 2019 is now published! Updated every five years by the Working Group on the State of the St. Lawrence Monitoring, the Overview provides a diagnosis of the state of the St. Lawrence River. To do so, partners analyze at regular intervals, some 20 environmental indicators related to water, sediment, biological resources, shorelines and uses of the St. Lawrence River. The results make it possible to assess the state of the ecosystem and to provide guidance for decision-making towards ensuring conservation and sustainability of the St. Lawrence.
