BRUNSWICK, Maine — Brunswick Marine Resources says shellfish harvesters took to the Brunswick clam flats Sunday to remove a “vicious clam predator that’s been wreaking havoc” in Maine’s intertidal zone in recent years.

The milky ribbon worm is believed to be causing moderate mortality to the soft shell clam population, according to the Brunswick Marine Resources.

The worms are found primarily in the clam beds and are stumping resource managers on how to mitigate the problem.

In the meantime, the Brunswick Marine Resources says harvesters are doing all they can to save some of their most productive flats.
