More Zebra Mussels Found in Upper Chesapeake Bay
Maryland Department of Natural Resources (DNR) biologists found young zebra mussels attached to buoys off Havre de Grace on December 3. DNR is asking boaters and anglers to be on the lookout for this harmful, invasive mussel.
The biologists collected 20 live zebra mussels attached to the concrete anchor blocks for three channel marker buoys. DNR discovered the mussels when Captain Shawn Orr and the crew of DNR’s A.V. Sandusky pulled the buoys from the water for cleaning and winter storage.
“We know that these mussels are from this year’s spawn since these buoys and anchors were deployed this spring,” said Matt Ashton, a DNR biologist and mussel expert who helped collect the mussels. “We plan to check these and other buoys every fall, as part of DNR’s limited zebra mussel monitoring effort in the upper Bay area.” ...
DNR asks that people who live and work on the water keep an eye out for zebra mussels and call 410-260-8615 if they find anything suspicious. More information about zebra mussels can be found here.
The non-native and invasive zebra mussel was first found in Maryland in late 2008 at two locations in the Susquehanna River: the Conowingo Dam and further upstream at Glen Cove Marina, Harford County. Sporadic sightings since then indicate establishment of a zebra mussel population in the lower river and downstream dispersal, but no apparent rapid increase in abundance. ...
