Marine Bioinvasion: Ecological Risks and Implications for Maritime Safety

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.

压载水对于船舶的稳定至关重要，它确保了船舶、货物和船员的安全。这一做法对于控制船舶吃水深度、维持船舶直立以及防止船舶倾斜具有决定性意义。尽管压载水对航海至关重要，但它是海洋生物入侵的主要原因。当船舶携带压载水时，水生生物会从其原生社区迁移至新的生态系统，可能导致引入外来物种，威胁当地生物多样性。全球航运业每日在其压载水中运输各种物种，这种引入可能引起生态失衡，对沿海经济活动产生负面影响。此外，压载水中可能含有病原体，对公共健康构成风险。对海洋生态系统影响的认知至关重要，同样重要的是开发无生物杀灭剂的水生物防污研究以及实施压载水处理系统。
