MIB Info Update: Ballast Waters and Aquatic Invasive Species
In response to an article that ran in the daily newspaper Le Devoir on March 18, 2017, the Marine Information Bureau (MIB) would like to clarify a few things regarding ballast water management measures applicable to vessels navigating in Canada.
Ballast water – What is it?
Ballast water is essential for the safe operation of merchant ships, allowing them to navigate at the proper depth and ensuring their stability. Ballasting is necessary when a vessel carries heavy cargo in one hold and a lighter load in another, when it is travelling empty or when the sea is rough.
When ballast waters are discharged, non-indigenous, potentially invasive, aquatic species may be introduced. However, international and Canadian regulations have been in effect for a number of years now (2004 and 2006 respectively) to address this problem.
