Information for aquaculturists

In The Netherlands Undaria has become a major pest of mussel growers (see Impacts page). While Undaria is capable of spreading short distances on its own (see Life Cycle page), accidental spread via aquaculture gear and species can speed up the rate of spread and result in new areas being infested.

Undaria can attach to nearly any material left in saltwater, including aquaculture species. Accidental spread via aquaculture equipment is thought to be the route by which Undaria has spread in some locations. You can help prevent the spread of Undaria and other marine pests in a number of ways.
