An invasive species of fish has been sighted for the first time at Kejimkujik National Park in Nova Scotia, and officials are doing everything in their power to prevent it's spread. A chain pickerel was caught in a river attached to Kejimkujik Lake. Resource conservation manager Chris McCarthy is shown standing with one of the barriers installed to prevent the spread of invasive species into Kejimkujik National Park. "The whole brook trout fishery at Keji national park is at stake if we have invasive species come in, there's no doubt about that,"Chris McCarthy demonstrates the mesh barrier used to prevent invasive fish from entering the park. "That way, the native fish species really have a good chance of surviving."
