B.C. freedivers help scientists remove invasive green crabs to protect coastal ecosystems.

B.C. freedivers are teaming up with scientists to combat the spread of invasive European green crabs in coastal waters, helping to monitor and remove the crustaceans from sensitive ecosystems. The effort, part of a broader conservation initiative, leverages divers' access to underwater habitats to identify and capture crabs, reducing their impact on native species and shellfish populations.
