Northeast Marine Introduced Species (NEMIS) - Print Edition

Pathways and Prevention : Shipping

Shipping is often considered the major pathway for marine introductions. Commercial shipping (both international and within the country), recreational boating, cruise ships, and small commercial vessels (such as fishing, barges, and ferry boats), can all serve as pathways for the movement and introduction of species. The most common shipping-related pathways for introduction of non-native marine species include via ballast water, hull fouling, sea chests, other seawater discharges, and other areas of ships where plants or animals can attach.
