Introduced species remark In Baltic Sea (IHO Sea Area) : In the Baltic Sea, A. improvisus is reported to affect the recreational quality of shorelines by fouling rocks and littering beaches with its sharp shells. On the other hand, its large filter-feeding biomass increases the clarity of the water (Olenin and Leppakoski 2000). [details]
Introduced species remark in Swedish Exclusive Economic Zone (EEZ) : In Skagerrak, Sweden, it was the dominant organism fouling the hulls of recreational boats, probably because it was more tolerant of hydrodynamic stress than the native Blue Mussel, Mytilus edulis, which dominated static fouling plates (Berntsson and Jonsson 2003). In Sweden, estimated costs of hull fouling by A. improvisus are 23-56 million dollars per year (Gren et al. 2009). [details]
Introduced species remark In Baltic Sea (IHO Sea Area) : In the Baltic Sea, where it is the only barnacle species present, filter-feeding by A. improvisus is thought to affect food webs by diverting planktonic production to the benthic biomass (Olenin and Leppakoski 2000). [details]
Introduced species remark In Gulf of Bothnia (IHO Sea Area) : In the Gulf of Bothnia, A. improvisus was classified as having some habitat impacts, by fouling eelgrass and algae (Bostrom and Bonsdorff 1997 and Raberg and Kautsky 2007, cited by Zaiko et al. 2011). [details]
Introduced species remark In Gulf of Finland (IHO Sea Area) : In the Gulf of Finland, A. improvisus was classified as having moderate ecosystem impacts (Zaiko et al. 2011). [details]

Introduced species remark In Sea of Japan (IHO Sea Area) : In the Caspian Sea and in Russian harbors on the Sea of Japan, A. improvisus was an important component of fouling on harbor structures (Kashin et al. 2000; Zaitsev and Ozturk 2001; Zvyagintsev 2003). [details]
Introduced species remark in Swedish Exclusive Economic Zone (EEZ) : Amphibalanus improvisus is a frequent fouler of power plants in its native and introduced range (Nauman and Cory 1969; Vuorinen et al. 1986; Zvyagintsev et al. 2003). In Sweden, estimated costs of power plant fouling by A. improvisus were 1.5-5.5 million dollars per year (Gren et al. 2009). [details]

Alien species The origin of the Bay barnacle Amphibalanus improvisus is unclear, and therefore referred to by many scientists as cryptogenic. It is a typical fouling species that distributes itself by clinging to ship hulls.In Belgium, living Bay Barnacles were first reported in 1895. There were even specimens found in archaeological materials dating back to the 17th century. This barnacle can compete with local species for food and space, but it can also influence the occurrence of algae, as seen in the Baltic Sea. [details]
