Stavanger, Rogaland, Norway |
On 2 November 2020, the Japanese invertebarate Didemnum vexillum was detected by diver and underwater photographer Erling Svensen at Engøyholmen in Stavanger harbor. The aim of a new monitoring project is to register occurrences of the presumed recently arrived D. vexillum in the delimited areas, and then to map how it spreads locally, and also what impact it has on the local fauna.
