WSG Crab Team Trip to Makah Bay

August 8th, 2018

Last month, Washington Sea Grant Crab Team staff traveled to the Makah Reservation in the northwest corner of the Olympic Peninsula to participate in the Makah Tribe’s European green crab trapping efforts. As you might remember, in October of 2017, we reported the very first sighting of a green crab in Makah Bay. Since then, Adrianne Akmajian, Marine Ecologist for the Makah Tribe, has been leading extensive trapping efforts to better understand and manage the population ...

CORRECTION: First European Green Crab Confirmed in Port Angeles

February 5, 2018: CORRECTION

Since this report was made, we have determined that the evidence originally submitted of the crab’s identity was not verifiable as a direct observation of the crab. Because European green crab is currently very rare in Washington’s Salish Sea, the majority of reports are of mistaken identity. This is why photographs of the crabs captured are required before we can confirm a sighting. It is therefore with some relief that we retract this ...

October 25, 2017

At the end of August, Crab Team received an email on our “tip line” from a beachwalker who had spotted a European green crab near Hobuck Beach in Makah Bay. The photograph submitted enabled us to immediately confirm the sighting, which was a new record for that area. The crab was located on Makah tribal land, and the Makah subsequently undertook a rapid assessment trapping effort to determine the extent of any green ...

European Green Crab Captured on Whidbey Island

September 19, 2017

Crab Team volunteers at Lagoon Point, on the west side of Whidbey Island, captured a single European green crab in their final sampling effort for this year. The male crab, at 47 mm across the carapace, is most likely a 2017 crab, part of this year’s cohort. A team of four volunteers from the island has been monitoring the site, April through September, for the past two years, but this is the first evidence of European green crab ...

European Green Crab Found in Sequim Bay

August 23, 2017

A single European green crab was captured in Sequim Bay last week by Neil Harrington, an Environmental Biologist with the Jamestown S’Klallam Tribe. Since the discovery of a small population of green crab in nearby Dungeness Bay this April, Harrington has been steadily trapping his way around Sequim Bay on the lookout for more of the invaders. Intensive trapping by Harrington and coworkers over the last week did not capture any additional European green crab, suggesting that ...

Evidence of Predation on European Green Crab from Padilla Bay

August 14, 2017

It looks as though Crab Team, now a network of 52 early detection sites monitored by more than 200 volunteers and several dozen staff from partner agencies, might have another ally out in the mud. Last week, during regular monthly sampling in a channel at the south end of Padilla Bay, Lindsey Parker found a European green crab. This was definitely notable, because we would rather not find any green crab, but not entirely surprising because the monitoring ...
