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 ...

Building Capacity to Protect the Salish Sea From European Green Crab

 July 5th, 2018

As we wrote last week, the first half of this monitoring season has seen several new detections of European green crab, but as green crab appear to be ramping up, so is the group of humans ready to control them. WSG Crab Team is now a project with five team members (including two full time staff), more than 200 volunteers, and 25 partner staff from agencies and tribes. That’s a lot of people ...

Single Green Crab Found During Follow-Up Assessment on Whidbey Island

June 11, 2018

Last week, WSG Crab Team spent three full days in the mud at Lagoon Point on Whidbey Island. After two European green crab were discovered there last year, one during regular volunteer monitoring and a second during the subsequent rapid assessment, Crab Team HQ decided another multi-day trapping assessment could help us better understand the status of green crab at the site. ...

HEOR or HENU?

May 11, 2018

HEOR or HENU? Crab Team volunteers know it’s one of the most challenging questions we face during sampling. Telling hairy shore crabs (HEOR) apart from purple shore crabs (HENU) can be very tricky, especially when all you have is two tiny molted carapaces. It’s not only shore crabs; several groups of crabs can be tricky to distinguish from each other, even if you know what you are looking for.

As you learn a new set of species, whether it’s birds, ...

Protocol In Focus: HEOR Parasites

May 10, 2018

One strength of the Crab Team protocol is that it enables us to confidently compare findings among sites, and track changes over time – even if different people are doing the sampling. With sampling on this scale, even the small steps can be important to what we learn from the data. Protocol in Focus allows us to expand on these details, and offer an opportunity to see all the behind-the-scenes planning that goes into methodology.

Where are the European Green Crab in the Salish Sea Coming From?

April 25, 2018

Finding a few isolated pockets of invasive European green crab in Washington’s Salish Sea over the past two years indicates the early stages of a possible range expansion. Certainly, it is the goal of WSG Crab Team and management to protect shorelines from the damage this crab has done in other parts of the world. In order to do that, it’s important not only to know where green crab are found – and to try to remove them ...

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 ...

New Coastal Site for European Green Crab: Makah Bay

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 ...

Trapping for European Green Crab on Whidbey Island

October 12, 2017

Following the recent capture of a single European green crab at Lagoon Point, on Whidbey Island (read more), Crab Team staff and volunteers, in consultation with the Washington Department of Fish and Wildlife (WDFW), headed back to the site last week to carry out assessment trapping as an expanded early detection effort. Over three days, the group conducted 114 trap sets, and captured only one additional European green crab.

This type of assessment trapping is the first step ...
