Marine Bioinvasion: Ecological Risks and Implications for Maritime Safety
Description
Ballast water is essential for the stabilization of ships, ensuring the safety of the vessel, cargo and crew. This practice is crucial for controlling the ship’s draft, keeping the vessel upright and preventing it from listing. Despite its importance for navigation, ballast water is the main cause of marine bioinvasion. When ships carry ballast water, aquatic organisms are moved from their local communities to new ecosystems, which can result in the introduction of exotic species that threaten local biodiversity. The global maritime sector transports a variety of species in its ballast water every day, and this introduction can cause ecological imbalances, negatively affecting coastal economic activities. In addition, ballast water can contain pathogens, posing risks to public health. Awareness of the impacts on marine ecosystems is essential, as is the development of biocide-free antifouling research and the implementation of ballast water treatment systems.
