Final answer:
Spraying other vessels, weaving between other vessels, playing "chicken" with other vessels, jumping boat wakes, etc, are examples of boat maneuvers that can lead to the transport and introduction of aquatic nonindigenous species (NIS).
Step-by-step explanation:
Spraying other vessels, weaving between other vessels, playing "chicken" with other vessels, jumping boat wakes, etc, are examples of boat maneuvers that can lead to the transport and introduction of aquatic nonindigenous species (NIS). Commercial shipping is a major vector for the dispersal of these species through ballast water and hull biofouling of vessels. The global fleet of commercial ships provides the opportunity for species transfers across an extensive network of routes, allowing organisms to breach historical barriers to dispersal.
