What is the objective of ballast water management?

• A. To maximize ballast water capacity
• B. To prevent the transfer of invasive aquatic species via ballast water
• C. To discharge ballast water as quickly as possible
• D. To increase ship stability by adding water

Answer: (B)

Preventing the transfer of invasive aquatic species through ballast water is the objective. Ballast water is taken on to keep a vessel stable and level when it isn’t carrying cargo, and when that water is discharged in a different location, organisms from one ecosystem can be released into another. These introduced species can become invasive, disrupting local ecosystems, harming native species, and impacting fisheries and port operations. Ballast water management aims to minimize this risk by treating ballast water (through filtration, disinfection, or other treatments) or by exchanging it away from shore in deep water to reduce survivability. In short, the goal is environmental protection and ecological safety, not increasing capacity, speeding discharge, or altering stability without safeguards.
