Pest Identification

Slowing the spread of marine pests requires cooperation from all users of our marine resources. Knowing how to identify marine pests can be a useful tool in preventing the spread of these pests. If you see a marine pest outside of its current distribution, please contact the Marine Environment Section of the Department (see below). There are several key marine pests in Tasmania.
