THE SHIP AS A VECTOR IN BIOTIC INVASIONS

Ship hull exteriors, seawater pipe systems, ballast water, sewage holding tanks and treatment plants, and anchors and chains play a role in the inadvertent export and import of live organisms. Ballast water movement is believed to be the major vector today of the transoceanic and interoceanic dispersal of exotic species. Recent examples of the significance of this movement in the Great Lakes (in particular the introduction of the European zebra mussel) and elsewhere are noted. A number of control options to this biotic dispersal problem are listed and discussed. The International Maritime Organization (IMO) is identified as the logical center for the oversight and enforcement, via its MARPOL Convention, of global control of ballast water release.
