After delivering their cargo, empty commercial ships need to take up water from the port of arrival in order to maintain stability and ensure safe navigation conditions before heading back to the port of departure. This water, called ballast water, which contains aquatic organisms typical of the port of arrival, is stored in ballast tanks and is ultimately discharged at the port of departure when the ship is ready to be re-loaded. During this process, aquatic organisms capable of surviving in ballast water are released into new environments and can therefore become invasive species, causing serious economic and public health issues.
