The discovery of mature zebra mussels on the hydroelectric dam in Edmundston, New Brunswick, at Maine’s border where the Madawaska River flows into the St. John has put the state’s biologists on higher alert. Zebra mussels could already be establishing themselves in the St. John River, according to an invasive species biologist at the Maine Department of Inland Fisheries and Wildlife. Zebra mussels are filter feeders that very quickly drain nutrients from a body of water, which would endanger some of Maine’s prime fisheries.
