Eradication of Alien Invasive Fish Species

Eradication of Alien Invasive Fish Species

Native biodiversity in European waters is under attack from non-native, invasive, alien fish species, and from parasites, especially the salmon parasite Gyrodactylus salaris.

Both intentional/ authorized an unauthorized introductions are the reasons for undesirable introduction of invasive alien species. Many of these species are causing economic and environmental problems, such as reduced biodiversity. Globally, invasive alien species have been recognized as the second greatest threat to biodiversity after habitat loss (international Union for Conservation of Nature, IUCN). The EU regulation 1143/2014 recommends rapid actions as eradication of invasive alien species.

The natural piscicide, rotenone, is a valuable management tool in restoration programs and for protection of the biodiversity in aquatic systems.
