American Samoa invasive species and action plan.
BRB
Available Online
2017
American Samoa invasive species strategy and action plan for the only US territory in the South Pacific being such is faced with unique threats with its location from a national perspective and has a need for both nation al and regional collaborations. The ecological integrity of American Samoa is of utmost importance in the face of invasive species. The cultural identity of American Samoans is also closely tied to the ecological integrity of its natural environment. And given its a highly limited economy, any impact by invasive species on its natural ecosystems that provide goods and services will be almost immediate. The establishment of an invasive species plan, with its clearly articulated priority actions, goals and objectives will provide a guidance to deal with the threats of invasive species. The implementation of the plan will: (1) increase awareness of their threats; (2) inspire cooperation to prevent and minimize their impacts and implement appropriate approaches; and (3) improve decision making through the process of data and information sharing from the best available science. Priorities are: Implement urgent and necessary actions; Enhance capacities for informed decisions; Advance preventive and rapid-response protocols and measures.
Small- and large-scale eradication of invasive ?sh and ?sh parasites in freshwater systems in Norway
Island and Ocean Ecosystems, BRB

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.
