Friday, 8 June 2018

A new study of European Alien Species Information Network (EASIN) identifies the origin (native distribution range) of the marine non-indigenous species established across the European Seas (824 species), and the primary pathway of their introduction, based on the data of the EASIN. 

  • The vast majority of the marine non-indigenous species originate from the Western and Central Indo-Pacific, in particular for species introduced in the Eastern Mediterranean.
  • A significant number of species originate from the Temperate Northern Pacific, NE Atlantic and Tropical Atlantic, in particular for species introduced in the Black Sea, Great North Sea and Western Mediterranean.
  • Time trends reveal a general decrease in species introductions originating from the Temperate Northern Pacific.

The assessment of the origin and the associated pathways of the marine non-indigenous species can support tailored management of specific pathways per marine European region, focusing to prioritization efforts.
