Association with vessel vectors (?) | Ballast waters Biofouling References: Sjøtun, K., Husa, V., & Peña, V. (2008). Present distribution and possible vectors of introductions of the alga Heterosiphonia japonica (Ceramiales, Rhodophyta) in Europe. Aquatic Invasions, 3(4), 377-394. Comments: In warer European waters its introduction is linked to shellfish trade; in North Sea and Scandinavia, however, it seems more likely transported via vessels. Fragments were bserved alive in ballast waters in some ships from Asia to Europe (France); it is also possible that it came attached on hulls as biofouling. |
