Ballast water contains a variety of organisms, such as marine and coastal plants and animals from different regions of the world. While the majority of the organisms will no longer be alive in the ballast water tanks of the carriers when the ballast is discharged, some may survive and prosper in their new environment. These “non-native species” can have a serious ecological, economic and public health impact on the receiving environment.
