Over the summer, DFO and Saint Mary\u2019s University researchers trapped and removed 70 live red swamp crayfish from Three Mile Lake, located next to Windsor Junction.<\/em><\/p>\n During a media presentation along the Cobequid Road shore of the lake on Thursday, DFO aquatic invasive species biologist Sarah Kingsbury told reporters this type of crayfish has \u201csevere or potentially severe\u201d impacts on ecosystems. It preys on fish eggs, competes with native species for available resources, space, and calcium in the water. It can also alter the physical habitat structure and impact other species through its burrowing.<\/em><\/p><\/blockquote>\n Yvette d\u2019Entremont cites Saint Mary\u2019s University researchers as urging anyone who spies a crayfish in Nova Scotia to contact them here<\/a>.<\/p>\n Thx for caring, Halifax Examiner\/Yvette d\u2019Entremont, & Saint Marys University folks.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" This new invasive species is featured in an item in today’s Halifax Examiner’s Morning File and in an associated article by Yvette Entrmonet DFO: Red swamp crayfish trapped in Halifax area lake could have \u2018severe\u2019 impact on ecosystems.
