About the Event

Join the New Hampshire Green Crab Project to search the coast for green crabs! Volunteers will contribute to a study evaluating the potential for a commercial fishery to help control this invasive 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). The event will start with a brief training in crab identification and survey methods. Then we will survey the coast together for green crabs!

Accessibility: Participation in this project requires walking on rocky shorelines and uneven terrain. Waterproof shoes are highly recommended, but not necessary.

What to bring

Dress for the weather! Sunscreen, hat, closed-toed shoes/boots.
