The European green crab might be small, but it can destroy vital habitats for animals all along the food chain. It’s already costing New England shellfisheries million of dollars.
In July 2020, green crab were found in Haida Gwaii, the closest they’ve ever been to Alaska. With the help of volunteers, the Alaska Department of Fish and Game hopes to stay one step ahead of the invasive species.
At low tide at Sandy Beach in Petersburg, Sunny Rice and a group of volunteers walked toward a crab trap — on the lookout for European green crab.
Green crab are small but mighty, measuring around 3 or 4 inches wide. Their shells are a dark, greenish-brown shell with yellow spots, with five triangular points on either side of the eyes.
