Great Marsh Projects

Green Crabs are an invasive species that seriously threaten the natural resources of Great Marsh, particularly softshell clams, mussels, and eelgrass meadows. Twenty-four permanent stations have been established in Plum Island Sound and Essex Bay to monitor green crab abundance for development of green crab management strategies.

Invasive Green Crab Management

Partnership member Green Crab R&D is creating new, high-end culinary commercial markets for the ultimate removal of invasive green crabs to help restore the ecological balance in the Great Marsh. This effort will generate a new source of revenue for commercial trappers and seafood wholesalers through market-driven incentives, while ridding the waters of a destructive, invasive threat.
