The European green crab is aggressive and feeds voraciously on shellfish. They have no natural predators and reproduce at high rates. Each female can have up to 185,000 offspring at a time. Prime concern is the impact on eelgrass, a critical habitat for young salmon. The invader was introduced in California 3 decades ago and is steadily moving north. In the past 3 years they have appeared in Haida Gwaii and their numbers are huge and growing. |
Conservation groups trap crabs by the tens of thousands and freeze them to kill them. They are crushed and used for compost. |
