Ballast water management in Canada: A historical perspective and implications for the future
Non-indigenous species (NIS) can create significant risks when introduced to foreign ecosystems. One of the many vectors facilitating the global transport of NIS is ballast water, and as commercial shipping increases so does the threat of ballast water-mediated introductions. Despite Canadian regula...

Non-indigenous species (NIS) can create significant risks when introduced to foreign ecosystems.
