Invasiviteit (toelichting) |
C. wailesii was probably introduced in European water with ballast water. After it was first detected in the English Channel in 1977, it spread rapidly along the Atlantic coast of France to Helgoland and Norway (Laing & Gollash 2002). It is distributed world-wide as it can easily disperse over large distinces by ballast water but also by natural distribution with the sea-currents. |

Ecologische impact (toelichting) |
It can form dense blooms, producing mucilage, inedible for most grazing plankton, threatening the benthic habitats. Mucilage can aggregate, sink and form a blanked on the seabed, causing anoxia (Laing & Gollash 2002) |
|
Economische impact (toelichting) |
The species can threaten fisheries and aquaculture while the mucilage, formed by blooms, can cause extensive clogging of fishing nets and other equipments benthic (Laing & Gollash 2002) |
