For the first time, the province of Nova Scotia is proposing to poison a lake to kill off an invasive species. It’s a last resort to stop the spread of smallmouth bass from a headwater lake that flows into the St. Marys River system, which is home to trout and a surviving Atlantic salmon population. “We want to eradicate them from this lake to ensure the integrity of the St. Marys River watershed is left intact,” says Jason LeBlanc Since the illegally introduced bass were first detected in July 2019, biologists have removed hundreds from Piper Lake in Pictou County.
