Association with vessel vectors
Actual evidence of being found in samples in a particular vector from any world region.
Anchor and anchor chains. Organisms found on anchors, anchor chain or within attached sediments, including anchor chain lockers.
Ballast water. Ballast water means water with its suspended matter taken on board a ship to control trim, list, draught, stability or stresses of the ship.
Biofouling. Biofouling means the accumulation of aquatic organisms such as micro-organisms, plants, and animals on surfaces and structures immersed in or exposed to the aquatic environment. Biofouling can include microfouling and macrofouling.
- Macrofouling means large, distinct multicellular organisms visible to the human eye such as barnacles, tubeworms, or fronds of algae.
- Microfouling means microscopic organisms including bacteria and diatoms and the slimy substances that they produce.
Biofouling comprised of only microfouling is commonly referred to as a slime layer.
Sea chest. The sea chests are cavities (an opening with protection grid) at the bottom side of the ships’ hull (an opening for pumping in and out water for, e.g., ballasting, firefighting) where aquatic organisms may settle and be transported.
Tank sediments. Matter settled out of ballast water within a ship.
