Town partners with Downeast Institute to deploy shellfish recruitment boxes for monitoring
Summary
Cumberland will host 24 shellfish recruitment boxes, placed at two sites on local flats in partnership with the Downeast Institute, to monitor clam recruitment, growth and environmental factors; boxes will be retrieved in the fall for analysis and volunteers from the shellfish commission and local high school will assist.
Police Chief Rumsey, speaking for the Cumberland Shellfish Commission, told the council that the town has entered a memorandum of understanding with the Downeast Institute (DEI) to participate in a shellfish recruitment monitoring program.
The plan calls for 24 wooden boxes — two sites with 12 boxes each — to be placed on town flats near Town Landing and Broad Cove Beach. The boxes create sheltered settling areas where tiny clam larvae can settle and be retrieved later for measurement. "When the clam larva are very tiny, they're small enough to go through the mesh that's on the top of this box. They'll settle inside that area, and then in the fall, these boxes will be collected, and they'll be able to take a look to see what happened inside these boxes," Chief Rumsey said.
The project will collect data on recruitment density, growth rates, predator impacts and seawater temperatures; DEI will compare results year‑to‑year and site‑to‑site along the coast. The town will publicize the placement with kiosk notices and a QR code linking to more information. Chief Rumsey and councilors also discussed signage and volunteer protections near tidal flats; DEI will return monitoring data late fall or winter after retrieval and lab processing.
