The growers recognized the crabs as invasive while handling oysters and sorting out other animals, and quickly reported them to Washington Department of ...

Just as it feels right to us to hunker down and stay warm, cooler water temperatures also cause green crab to become less catchable in the fall and winter.

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 ...

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 ...

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 ...
