Map of Maine Soft-Shell Clam Recruitment Network

The Downeast Institute is establishing the first ever clam recruitment monitoring network in nine towns spanning the entire coast of Maine. The network will measure clam and other shellfish recruitment as well as survival in two flats in each of the nine towns (n=18) in towns from Wells in southern Maine to Pleasant Point/Sipayik in eastern Maine.

DEI is partnering with the Wells Shellfish Committee, Scarborough Shellfish Conservation Commission, Brunswick Marine Resources Committee, Wiscasset Shellfish Conservation Committee, Bremen Shellfish Conservation Committee, Isleboro Shellfish Conservation Committee, Frenchmen’s Bay Regional Shellfish Committee, Beals Shellfish Commitee, and the Natural Resources Board of the Passamaquoddy at Sipayik to conduct the research. Clammers, municipal officials,  and community volunteers will work alongside DEI staff to collect data.

The study will use an array of 16 recruitment boxes deployed in the lower mid intertidal of two flats of each town. The boxes will be deployed before the beginning of the clam spawning season (and baseline sediment core samples will be taken to assess baseline densities of clams) and boxes will be retrieved at the end of the growing season. At the same time additional sediment core samples will be taken to assess the amount of recruit survival that occurred on the flat.
