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.
