About Us

SEMAC is an agency of Barnstable County, but the Center supports aquaculture interests in all of southeastern Massachusetts, including Barnstable, Bristol, Dukes, Nantucket, and Plymouth Counties. Funding is received from the Massachusetts Department of Agricultural Resources, and the budget is administered through the offices of Cape Cod Cooperative Extension. Priorities are determined by a thirteen member Board which meets twice a year. The SEMAC staff conduct research and monitoring, organize outreach and education events, administer grants, and serve as an unbiased source of information for shellfish and finfish growers in the region.
