For the first time, live invasive green crabs have been found in Alaska

Wildlife monitors in Metlakatla have found 13 invasive European green crabs in the waters around Annette Island — the first time they have been documented alive in Alaska, Alaska Public Media reports.

Staff from the community’s Division of Fish and Wildlife have been combing the beaches and waters around Metlakatla for the five-spined crabs, which federal officials have called one of the most invasive marine species around.

The crabs are largely falling into salmon traps around Tamgas Harbor. Shrimp pots are also being set to catch the crabs.

In a statement, the Tribe announced that officials are working with federal and state partners to conduct genetic analysis and outreach efforts.

“It is essential that we address this matter urgently as GC (green crab) target juvenile Dungeness crab, juvenile salmon, shellfish and mollusks,” the statement read.

“This species poses a real and present threat to our most critical subsistence and commercial resources.”
