Small- and large-scale eradication of invasive ?sh and ?sh parasites in freshwater systems in Norway

Bardal, H.

2019
In July 2016, the European Union adopted a list of invasive alien species of concern, and at present there are two freshwater ?sh species on the list. Member states are obliged to prevent further spread and to perform rapid eradication when problem species are discovered at new sites, but continental EU member states have limited experience with eradication of ?sh. Eradications are more likely to succeed if the invasive species is con?ned to insular habitats. Freshwater invasives can be regarded as island invasives, since their habitats have boundaries against shorelines, saline waters, waterfalls and dams, and these boundaries make eradications possible. CFT Legumine® containing rotenone is the only legal piscicide in the EU, and Norway has used CFT Legumine® in eradication e?orts for many years. Species that have been introduced outside their native range and have been successfully eradicated include minnow (Phoxinus phoxinus), roach (Rutilus rutilus), pike (Esox lucius), common white?sh (Coregonus lavaretus), and the salmon parasite Gyrodactylus salaris. This manuscript summarises the eradication e?orts of invasive ?sh species and ?sh parasite species during the last two decades in Norway, covering eradications from such diverse habitats as small ponds, lakes, marshlands, small streams and large rivers. An estimated £100 million has been spent in the Gyrodactylus salaris eradication programme. Costs of invasive ?sh eradications are given, ranging from less than £10,000 to more than £200,000. There are no known invasive ?sh eradication failures in Norway in the last 20 years. A summary of the e?orts in Norway can be an aid for planning control and eradication measures of invasive ?sh species in other countries.

This report provides an overview of the current state of knowledge of cetacean diversity, habitat and threats in the Pacifi c Islands Region. The boundaries of the Pacifi c Islands Region (Chapter 1), as defi ned by the Convention of Migratory Species (CMS) Memorandum of Understanding (MoU) for the Conservation of Cetaceans and their Habitats in the Pacifi c Islands Region (CMS 2006), are the marine areas under the jurisdiction of each Country or Territory of the Pacifi c Islands Region, and extend to the area defi ned by the Noumea Convention, i.e., between the Tropic of Cancer and 60° South latitude, and between 130° East longitude and 120° West longitude. The region stretches over some 10,000 kilometres from east to west and 5,000 kilometres from north to south, with a combined economic exclusion zone (EEZ) of approximately 30 million km². This region contains 22 Pacifi c Island Countries and Territories, as well as a portion of the Australian continent, both the North and South Islands of New Zealand, and a portion of the Hawaiian Islands. The region is purported to hold the most extensive and biologically diverse reefs in the world, the deepest ocean trenches, the world’s largest tuna fi shery, as well as a range of globally threatened species such as sea turtles, dugongs and cetaceans (UNDP 1999)
