Science advice on the effectiveness of ballast water exchange plus treatment as a mechanism to reduce the introduction and establishment of aquatic invasive species in Canadian ports. : Fs70-6/2019-003E-PDF

“Aquatic invasive species are a significant environmental stressor with widespread ecological impacts including biodiversity loss. The movement of ballast water via commercial shipping is a high-risk pathway through which harmful and/or non-indigenous aquatic species are introduced into novel ecosystems. The current management strategy, ballast water exchange, has varied effectiveness across different habitat types, and will be gradually replaced with a ballast water performance standard with the aim to achieve more consistent reduction of invasion risk. The Government of Canada proposed that the combined use of these management strategies may potentially achieve even greater risk reductions in fresh and brackish water environments than either strategy could alone, but additional scientific research is required to inform policy makers and risk managers about whether the exchange plus treatment strategy should be applied in Canada"--Context, page [1].
