Pathway risk management

Non-native marine species can be spread by humans in a variety of ways ('pathways'), including within ships' ballast water or biofouling, through movement of aquaculture equipment or stock and even through the marine aquarium trade. Their impacts on New Zealand's marine environments can be minimised by reducing the rate at which they are transported. This research focuses on reducing risks within national and international pathways for the spread of marine pests.
