44 invading species 'loose' in North Atlantic, study shows
Accidental introductions of non-native species has been of increasing concern since the 1980s when human-mediated transportation, mainly related to ships' ballast water, was recognised as a major route by which species are transported and spread.
Non-native species are a crucial issue that needs to be addressed to raise general awareness and publicity, alongside scientific surveys and monitoring, improved data availability, regulations, management tools, risk assessment, stakeholders' commitment, enforcement, best practices and constant surveillance.
