Species | Undaria pinnatifida | |
Date of the first record (?) | 2009 References (not structured): National Biodiversity Network Gateway http://data.nbn.org.uk [11 March 2013] Fletcher RL Manfredi C (1995) The occurrence of Undaria pinnatifida (Phaeophyceae, Laminariales) on the south coast of England. Botanica Marina, 38, 355-358. Floc'h JY, Pajot R, Wallentinus I (1991) The Japanese brown alga Undaria pinnatifida on the coast of France and its possible establishment in European waters. ICES Journal of Marine Science, 47: 379-390. Comments: It was first introduced to the coast of Brittany for cultivation and has since spread elsewhere in northern Europe. First recorded in Britain in The Hamble, Southampton water in 1994. First record in North Sea region was 2009 at marinas in Lowestoft, Walton on the Maze and Burnham on Crouch. Has extended its range northwards to Grimsby in the Humber Estuary by 2012. |
Recipient region (?) | Country: United Kingdom (Britain) LME: 22. North Sea |
|
Source region (?) | Ocean: Pacific --> Ocean region: NW Pacific References (not structured): Verlaque DM (2007) http://www.issg.org/database/species/ecology.asp?fr=1&si=68&sts; [11 March 2013] Comments: Occurs in the cold temperate regions of Russia, China, North and South Korea and Japan |
Pathway / Vector (?) | Level of certainty: Highly likely Pathway: Vessels Vector: (Highly likely) Ship’s hull References (not structured): Hay CH (1990) The dispersal of sporophytes of Undaria pinnatifida by coastal shipping in New Zealand, and implications for further dispersal of Undaria in France. European Journal of Phycology 25: 301-313. Farrell P, Fletcher RL (2006) An investigation of dispersal of the introduced brown alga Undaria pinnatifida (Harvey) Suringar and its competition with some species on the man-made structures of Torquay Marina (Devon, UK). Journal of Experimental Marine Biology and Ecology 334: 236-243. Fletcher RL, Manfredi C (1995). The occurrence of Undaria pinnatifida (Phaeophyceae, Laminariales) on the south coast of England. Botanica Marina, 38: 355-358. Comments: There is adaquate evidence to suggest that the species is spread by fouled ship and leisure craft hulls. the finds of the kelp in marina basins in docks, as in Grimsby, strongly supports this suppostion that it was introduced in this way to the North Sea British coast. |
Habitat type (?) | Aquaculture sites Estuary Lagoon Marina Port vicinity Ports Sheltered coastal area References (not structured): National Biodiversity Network Gateway http://data.nbn.org.uk [11 March 2013] Comments: The species can occur on exposed coasts but the current distribution in the North Sea is confined to estuaries and dock areas where there is small craft activity. |
|
Wave exposure (?) | Sheltered References (not structured): Nationa Biodiversity Network Gateway http://data.nbn.org.uk [11 March 2013] Comments: Most of the observations in the North Sea region are attached to floating structures such as pontoons and oyster rafts. |
|
Salinity range (?) | Exact range: 16 - 30 References (not structured): Curiel D, Bellemo G, Marzocchi M, Scattolin M, Parisi G (1998). Distribution of introduced Japanese macroalgae Undaria pinnatifida, Sargassum muticum (Phaeophyta) and Antithamnion Pectinatum (Rhodophyta) in the Lagoon of Venice. Hydrobiologia, 385: 17-22. Comments: This salinity range is for the sporophyte generation and the range is almost certainly greater than what Curiel et al., (1998) suggests. |
|
Temperature range (?) | Min: -1 Max: 23 References (not structured): Hay CH, Luckens PA (1987). The Asian kelp Undaria pinnatifida (Phaeophyta: Laminariales) found in a New Zealand harbour. New Zealand Journal of Botany, 25: 329-332. Comments: Different life history stages have different tolerance levels. |
Zonation / Substratum (?) | Benthic: Sublittoral within photic zone Substratum: Artificial (manmade) Biogenic (living or nonliving) Hard (cobbles to bedrock) References (not structured): Arenas F, Bishop JDD, Carlton JT, Dyrynda PJ, Farnham WF, Gonzalez DJ, Jacobs MW, Lambert C, Lamber G, Nielsen SE, Pederson JA, Porter JS, Ward S, Wood CA (2006).

Reproductive duration (?) | Medium References (not structured): Campbell SJ, Burridge TR (1998). Occurrence of Undaria pinnatifida (Phaeophyta: Laminariales) in Port Phillip Bay, Victoria, Australia. Marine and Freshwater Research 49: 81. Hay CH (1990). The dispersal of sporophytes of Undaria pinnatifida by coastal shipping in New Zealand, and implications for further dispersal of Undaria in France. European Journal of Phycology 25: 301-313. Comments: Zoospores are released at 9 to 20oC. Sporelings can separate from the adult plant and can survive once 8cm in length. | |
Reproductive seasonality (?) | Jul. Aug. References (not structured): Farrell P, Fletcher RL (2006). An investigation of dispersal of the introduced brown alga Undaria pinnatifida (Harvey) Suringar and its competition with some species on the man-made structures of Torquay Marina (Devon, UK). Journal of Experimental Marine Biology and Ecology 334: 236-243. Comments: The kelp undergoes sexual and asexual reproduction. According to Campbell & Burridge (1998) zoospores are released once temperatures attain 10oC. When the ten-day water temperature is maintained at 14oC, release of spores takes place according to Saito (in Farrell and Fletcher (2006). |

Migration pattern (?) | Unknown |
Population status (?) | Established (Low level of certainty) References (not structured): Arenas F, Bishop JDD, Carlton JT, Dyrynda PJ, Farnham WF, Gonzalez DJ, Jacobs MW, Lambert C, Lamber G, Nielsen SE, Pederson JA, Porter JS, Ward S, Wood CA (2006). Alien species and other notable records from a rapid assessment survey of marinas on the south coast of England. Journal of the Marine Biological Association of the United Kingdom, 86, 1329-1337. Comments: At marinas populations can be made up of many plants attached to the near-surface of the floating pontoons. |
