BALLAST WATER

SLIKA 2

Ballast water is considered as one of the most important vectors of the transportation of invasive alien species (IAS) in aquatic ecosystems.

The world’s ship transport of the ballast water stands at about 12 E9 t per year. It is estimated that ships’ ballast tanks can transfer at least 10,000 different marine species globally per day.

Ballast has unique role in cargo shipping. When ships are loaded with cargo, they do not need to carry ballast because the cargo provides stability to the ship. However, after the cargo is off-loaded from a ship, ballast must be taken on board. Ballast water discharged from ships acts as an inoculating mechanism for invasive species such as viruses and bacteria, dinoflagellates, diatoms, zooplankton, benthic fish, as well as eggs, spores, seeds, cysts and larvae of various marine organisms.

Damaging effects

Damaging effects of the IAS introduced via ballast water are recorded in the seas all over the world, having considerable economic, ecological, and environmental impacts, including the loss of native biological diversity
Consequently, they can negatively affect numerous sectors, such as fisheries, tourism, forestry, agriculture, utilities, water use, natural areas, etc. The costs of such impacts in the world are estimated to exceed 100 billion US$ per year.
