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.
