Introduced brown algae in the North East Atlantic, with particular respect toUndaria pinnatifida (Harvey) suringar
1998
Fletcher, R. L. | Farrell, P.
The recent introduction of the macroalgaUndaria pinnatifida (Harvey) Suringar into the North Atlantic is the latest of a large number of introductions, which have occurred over many years. Some have been deliberate introductions for mariculture or research, while most have been accidental, via vectors such as shipping and shellfish imports. Not all newly recorded species are introductions; some are thought to be merely extensions of distribution, e.g.Laminaria ochroleuca, while others may have been overlooked previously, e.g.Scytosiphon dotyi. Subsequent to its accidental introduction into the waters around the Mediterranean French coast at Sete, most likely with imported oysters,Undaria was deliberately introduced into the North Atlantic, to Brittany, in 1983 by IFREMER for commercial exploitation.Undaria has since spread from the original sites in Brittany, and is now established at several sites on the south coast of England. This paper discusses the introduced brown algae in the North Atlantic and outlines the establishment ofUndaria in the UK.
