Presented to ICES Working Group on Introductions and Transfers of Marine Organisms. Gdynia Meeting, March 2020. 6 pp. Comments: Considered established in NOBANIS database but only sporadically occuring according to www.frammandearter.se It has been suggested that the outbreak at the Swedish west coast is linked to the exceptionally warm summer of 2018 following either a climate-driven range shift or a direct introduction to the area via shipping activity (Govindarajan et al. 2019). |
