The following topics will be addressed: - no-native organisms or categories of them that are particularly potent to cause large-scale environmental problems (biodiversity i n particular) and/or economic effects - ecosystems and indigenous species that are particularly sensitive to the impact of alien species - risk assessment for selected harbour areas, incl. ecological criteria and prerequisities (e.g., salinity and temperature conditions, availability of habitats, turbidity, eutrophication, pollution) for probabilities of harbour areas to act as receivers and/or donors - studies of existing vectors in selected, international harbours, including harbour profiles with regard to import/export of ballast water, i.e., a origin/destination profile for imported/exported ballast water. harbours studied: Turku/Finland, Klaipeda/Lithuania, Göteborg-Stenungsund/Sweden, and Sture Oil Terminal/Norway - suggestions of measures and strategies to be employed to tackle the problem - the need for further research, and suggestions to monitoring activities
