Invasive Species

The third element of the Marine Debris Add-ons protocol is conducting surveys for invasive marine species, both plant and animal. Invasive species have been, and continue to be, introduced to NSW waters by a variety of means; including bio-fouling on hulls and inside internal seawater pipes of commercial and recreational vessels, ballast water discharged by commercial shipping, aquaculture operations (accidentally and intentionally), through aquarium imports, as well as marine debris and ocean currents.


The NSW Department of Primary Indiustries has idenified a number of invasive species that threaten the environment and economic values of NSW marine waters. Information, includng descriptions of each, can be accessed at:
