On a Metlakatla beach, scientists and concerned Alaskans recently got a firsthand look at the European green crab — an invasive species that showed up in Southeast Alaska last summer.
At a workshop in Metlakatla last month, citizen scientists learned from experts how to look out for the invasive crabs in their own communities.
Taylor Stumpf tries to get a crab out of a trap to check if it is a European green crab or a Dungeness crab. Stumpf explained a few key tells for a crab that doesn’t belong. Wildlife officials also handed out laminated guides showing pictures of the green crab to all the participants. “They usually like chum and herring fish,” Booth said. “We haven’t really used cat food like they suggested.”“Eelgrass is important because it’s like habitat for other clams, and like juvenile fish, juvenile salmon,” Booth explained. “So it was kind of a worry for us when they first arrived. And I’ve noticed that they’ve gotten a lot shorter, too, like, the eelgrass.”An invasive green crab found near Tamgas Harbor last month.
Each female crab is capable of laying hundreds of eggs. In Metlakatla, green crab catching is a full day’s work. Just ask Gabriel Nathan.
