‘Explosion’ of invasive European green crabs reported in Southeast Alaska - Chilkat Valley News

Invasive European Green Crabs in Southeast Alaska

The Metlakatla Indian Community has been leading the effort to control the invasion, trapping over 40,000 crabs this year.

In July 2022, a Sealaska intern found the first evidence of European green crab presence in Alaska, a discarded shell on a beach on Annette Island.

Since then, the Metlakatla Indian Community and its partners, including Alaska Sea Grant, have discovered more shells and live invasive crabs, with numbers growing from a handful to thousands.

This year, the tribe's team has trapped over 40,000 crabs on and around Annette Island, according to a representative.

The findings signify an "explosion" of invasive European green crabs in Southeast Alaska.
