Environmental DNA (Part 2): A Cautionary Carp Tale

March 3, 2022

This is the second in a series of posts sharing new research on the use of environmental DNA (eDNA) in detection of green crabs. For our introduction to eDNA, check out the previous post.

As a detection tool, the process of sampling eDNA is relatively simple, but interpreting results can actually be more complicated than you might expect. While the laboratory process and equipment might tell you – within some window of tolerance – whether green crab DNA ...

Environmental DNA (Part 1): Green Crab Monitoring 2.0?

February 24, 2022

Early detection is one of the best ways to thwart an invasive species, but trying to find some of the first individuals to arrive in a new habitat is no easy task. WSG Crab Team built a monitoring network to meet this challenge: by using multiple search methods and finely tuning the search protocols for green crabs, we hope to be able to uncover evidence of green crabs even while they are still extremely rare. Early detection successes ...

Coastal Green Crab Captures Increased in 2021

January 20, 2022

Trapping throughout 2021 indicates that the European green crab invasion has grown across Washington’s coastal estuaries, namely Willapa Bay, Grays Harbor, and Makah Bay. This year’s collaborative efforts by many partners to remove crabs and track the invasion also confirmed that green crabs are more abundant and widespread in these locations than they are along inland shorelines, and will likely continue to increase.

A Collaborative Approach

2021 marked the second year of intensive and systematic trapping for European green ...

What Does the Invasion at Lummi Mean for the Salish Sea?

December 6, 2021

The recent report by the Lummi Nation of more than 70,000 European green crabs captured this year has many wondering what this could mean for efforts to prevent green crabs from establishing in the Salish Sea. This number certainly indicates that the population of green crabs within the sea pond on the Lummi Reservation has grown exponentially since their first detection in 2019 (Mueller and Jefferson, ...

Padilla Bay: In It For The Long Haul

August 23, 2021

August 30 of this year will mark the fifth anniversary of the first confirmed detection of invasive European green crab along the inland shorelines of Washington which occurred on San Juan Island. Three weeks later, the region will hit the same milestone for the second confirmed detection: Padilla Bay, near Mt. Vernon.

As home to a National Estuarine Research Reserve (NERR), Padilla Bay is one of the ...

Protocol in Focus: Is it a molt or a dead crab?

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.

The molt ...

Washington Sea Grant Provides a Food Security Rapid-Response to Tribal Communities During Pandemic

 

The pandemic revealed acute food insecurity, health risks, and economic vulnerabilities in fishing communities in Washington State, particularly amongst Washington tribal nations who grappled with these challenges in addition to direct COVID-related impacts that included outbreaks, quarantines, closures and delayed harvests.

 Washington Sea Grant initiated two pilot demonstration projects for the Makah and Lummi Tribes, to swiftly deliver food security and extension services while building resilient marine food systems within these coastal communities for future catastrophic events. They coordinated a seafood ...

Completing the First Year of a Collaborative Removal Effort at Drayton Harbor

December 23, 2020

One of the big successes this year was the launch of a local removal effort in Drayton Harbor. In spite of COVID, in spite of wildfire smoke, in spite of everything that 2020 had to throw at us, the collaborative management team was able to make great strides in trapping the Washington’s northernmost green crab hotspot. From May through October of this year, the crew was out trapping, trapping, and … trapping, with two ...

2020 Salish Sea Green Crab Update

November 23, 2020

Trapping for European green crab has mostly concluded for the 2020 season, enabling us to take stock of all that was accomplished this year and provide some status updates on green crab. The obstacles this year were considerable, but volunteers and managers were more than equal to the task, masking, attesting, and distancing, not to mention riding out wildfire smoke, to trap for green crabs. The next few posts will provide updates on what was accomplished and what ...
