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.

Allogenic ecosystem engineers. Organisms which modify the environment by causing physical state changes in biotic and abiotic materials that, directly or indirectly, modulate the availability of resources to other species (e.g. excavating deep burrows which other organisms co-occupy, damming the water flow, etc).
