Upcoming Opportunity: Monthly summer 2018 Great Green Crab Hunts!
In summer 2018 we are hosting monthly Great Green Crab Hunts at various locations along the coast. Volunteers will come together for a quick training in green crab identification, and then we will search the coast for green crabs to collect important data on their locations and molt stages. This project is great for groups and families!
Fast Facts: What are Green Crab Surveys?
Volunteers are needed to search the coast for green crabs (Carcinas maenas) to contribute to a study evaluating the potential for a commercial fishery to help control this nonnative species. Green crabs are edible, but because they are smaller than other popular crabs, they are not commonly harvested for food. To this end, NH Sea Grant is researching when green crabs molt to explore the feasibility of a soft-shell crab market (similar to blue crabs). Green crab surveys are conducted as part of NH Sea Grant's NH Green Crab Project.
Volunteer Description: What do Green Crab Survey volunteers do?
Volunteer Experience: Volunteers will receive a brief training in crab identification and survey methods with Sea Grant biologist Dr. Gabby Bradt. Small groups of volunteers will then choose a location on the coast to conduct a crab survey, and volunteers will depart for their survey locations. Once you're trained, you can survey for green crabs anytime you're near the coast--the more data, the better!
Time Frame: Expect to spend about two hours in the training and on your survey. Once trained, you can conduct brief surveys near the coast anytime you'd like.
Project Impacts: The green crab is an invasive species that has wreaked ecological and economic havoc along the New England coast for decades. As ocean temperatures have increased, the populations of these crabs continue to explode. Currently, there is no strategy in place to control the populations of green crabs, and there is no real commercial market or fishery for these invaders. The goal of the NH Green Crab Project is to identify a clear window of time when male and female green crabs are molting as part of the exploration of the soft-shell green crab market and fishery in the Granite State.

Upcoming Opportunities: Join a Green Crab Survey!
Join us on April 14, 2018, for the first Great Green Crab Hunt. Green Crab Hunts will be held periodically throughout summer 2018. For more information on upcoming survey dates, keep an eye on our website or sign up for our newsletter.
There may also be opportunities for more in-depth volunteer experiences, including trapping green crabs and helping to process green crabs at Jackson Estuarine Laboratory. If you're interested in these additional volunteer opportunities, contact Sea Grant's Dr. Gabby Bradt at firstname.lastname@example.org or 603.862.2033.
