Marine Pests and Diseases
Not all introduced species have a significant impact on our marine life. Some find it hard to establish or compete in a new environment, or fall prey to our native species. However, many have the capacity to cause massive damage by displacing our native flora and fauna, by predating on native species or by becoming serious pests to our marine industries. These species are known as marine pests.
There are a number of recognised marine pests in Tasmania including the Northern Pacific Sea Star (Asterias amurensis)
, Wakame - Japanese Kelp (Undaria pinnatifida)
and the European Green Crab (Carcinus maenas)
Early Detection and Emergency Reponse
The Department utilises a range of information sources to maximise the potential of an early detection of any new marine pests. Community reports are an important part of our early detection capacity. When a new marine pest has been detected, national arrangements are in place to assist Tasmania mount an emergency response where it is deemed feasible and appropriate. It should be noted that there have been very few successful eradication programs for marine pests.
