Their numbers have been increasing ever since.


Maine Sea Grant sponsored a Green Crab Summit at University of Maine in December 2013.  Many Frenchman Bay Partners were in attendance.  The presentations provided a lot of detail about green crabs, their life history, and their impacts on shellfish populations and as well as salt marshes and seagrass beds.  They can be viewed at Several Frenchman Bay Partners, including representatives of the Bar Harbor Shellfish Committee, MDI Bio Lab, and Frenchman Bay Regional Shellfish Committee participated in a  one-day, state-wide survey of green crabs last summer, focusing their sampling efforts in Bar Harbor, Lamoine, Trenton, Sorrento and Sullivan.  The results of the survey can be found on the Maine DMR website .  The report concludes that green crabs are present throughout the state and in numbers that represent a detrimental impact to bivalve shellfish.
