Études de cas sur la gestion
A molecular detection method is being trialled for this species. The species-specific probes have been developed for three high-priority species in Australia's south-east:
1) The Northern Pacific seastar (Asterias amurensis); 2) The Pacific oyster (Crassostrea gigas); 3) The toxic dinoflagellate (Gymnodinium catenatum)
Development of the probes has been undertaken in partnership with shipping and port industries and the Australian Quarantine and Inspection Service. It has been funded by the Commonwealth Government's Natural Heritage Trust and the Victorian Government as part of the Port of Hastings National trial of ballast water management. The new DNA probe involves seawater sample extraction of DNA, and amplification of a target specific "DNA signature or fingerprint" to identify the presence of pest species in water. This means that aquatic pests in ballast water can now be confirmed without costly screening and can be uniquely identified at the larval and juvenile stages, a process welcomed by shipowners.

Résumé: The North European and Baltic Network on Invasive Alien Species (NOBANIS) has developed a network of common databases on alien and invasive species of the region. By establishing a common portal access to IAS-related data, information and knowledge in the region is facilitated. The NOBANIS network has a national contact in each of the participating countries - Denmark, Estonia, Finland, Faroe Islands, Germany, Greenland, Iceland, Latvia, Lithuania, Norway, Poland, Sweden and the European part of Russia.
