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

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 ...

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 ...

New Sighting of European Green Crab in Padilla Bay

September 23, 2016

Hot on the heels of the recent capture of the first confirmed European green crab along Washington’s inland shorelines by Crab Team volunteers, a second individual live invasive crab was caught in Padilla Bay, near Mt. Vernon, earlier this week.

The individual crab is a 34 mm female, and the small size suggests she is a young of the year, possibly arriving as a larva last winter. The crab was found by staff of the Padilla Bay National ...

First sighting of European green crab in inland Washington confirmed

September 2, 2016

Crab Team volunteers discovered the first confirmed sighting of a European green crab along inland Washington shorelines while conducting their regular monthly monitoring earlier this week.

Volunteers at Westcott Bay, on San Juan Island, discovered the large adult male in one of their Fukui traps (the larger of the two types we use). Because the crab was an adult, it is believed that it washed in to the area as a larva in 2015 or 2014, possibly ...
