The human-mediated introduction and establishment of non-indigenous species (NIS) in the marine environment are of worldwide concern. The main vectors for species introduction are maritime transport by either transport of organisms via ballast water or biofouling, and aquaculture. Further spread of species might also occur by smaller vessels and pleasure craft. Climate change and rising temperatures facilitate their establishment in temperate regions since many NIS originate from warmer areas. Nowadays notable efforts are undertaken to prevent or at least minimize new introductions. Unlike terrestrial NIS, marine invaders are almost impossible to eradicate and therefore, avoiding introduction is the most important mitigation measure. The HELCOM Baltic Sea Action Plan recognizes this in its Management Objectives for Maritime Activities: “No introductions of alien species from ships”. 1.2 Purpose and aims Rapid Assessment Surveys (RAS) have been tested in many coastal areas and proven .....
