Invasive European green crabs have unfortunately been found in the Skeena Estuary.
Why does the invasive European green crab matter?
These small but highly adaptable crabs are a threat to Skeena salmon survival as they dig up eelgrass beds. Eelgrass beds are critical nursery and feeding habitat for juvenile Skeena salmon, eulachon, and Dungeness crab. European green crabs also prey on native species such as oysters, muscles, clams and other juvenile crabs.
It is critical that the eelgrass beds of the Skeena estuary are protected from the spread of European Green Crab.
What can you do?
Learn how to identify European green crabs. Adults can reach about 10 cm and have five points on either side of their eyes. Their colour can range from green to red or yellow. More identification details: https://marinedata.psf.ca/knowledge-hubs/aquatic-invasive-species/
If you find a European Green Crab:
· Take a photo
· Record the exact location, ideally with GPS coordinates
· Report the sighting to Fisheries and Oceans Canada at [email protected]
· Put it in a sealed container
· Transport it to a freezer
· Freeze for 72+ hours
· Dispose of it in a compost facility or landfill
Every sighting helps researchers track this invasive species and understand where it is spreading.
