In this paper,we briefly describe the environmental
impacts,and economic and social implications,of some
of the more invasive alien marine species,then we
describe the vectors responsible for moving marine
species around the world,emphasizing that ballast water
is only one of many vectors. Lastly,we describe the
international and domestic policy environment including
the current international instruments that apply to
the invasive species problem and recommend what
actions need to be taken to reduce the risk of future
invasions.
