Genus: Asterias Species: amurensis Native Distribution Origin Realm: Arctic, Temperate northern Pacific Native Region: Arctic, Northwest Pacific, Northeast Pacific Origin Location: Arctic Arctic ocean, Bering Sea, Bering Strait (Gauthier & Steel 1996) STATED Eastern Bering Sea from the eastern Chukchi Sea (Feder et al. We studied native and invasive seastars feeding under two mussel aquaculture sites in south-east Australia, to determine whether food-rich farm habitats are likely to be reproductive hotspots for the invasive seastar (Asterias amurensis) and whether the larger native seastar (Coscinasterias muricata) reduces the value of the farms for the invader. Asterias amurensis general information. Wallingford, UK: CABI, Invasive Species Specialist Group (ISSG), 2011. National Introduced Marine Pest Information System http://adl.brs.gov.au/marinepests/index.cfm?fa=main.spDetailsDB&sp=6000005721, NSW Department of Primary Industries. In Australia, the economic effects of the species are still being fully evaluated, but it is thought that if their spread continues, the soft sediment communities along the coast of Australia may be compromised. Genus: Asterias Species: amurensis Native Distribution Origin Realm: Arctic, Temperate northern Pacific Native Region: Arctic, Northwest Pacific, Northeast Pacific Origin Location: Arctic Arctic ocean, Bering Sea, Bering Strait (Gauthier & Steel 1996) STATED Eastern Bering Sea from the eastern Chukchi Sea (Feder et al. In the absence of abundant native predators, man-made habitats such as shellfish farms, fish farms and mussel-fouled infrastructure can be reproductive hotspots for invasive Asterias amurensis populations, simultaneously supporting orders-of-magnitude higher population density and elevated individual reproductive potential (Ling et al., 2012). Marine Ecology Progress Series Vol. Scripps Institution of Oceanography La Jolla, California http://massbay.mit.edu/publications/marinebioinvasions/mbi3_abstract_book.pdf, Goggin, C.L., 1998. ("Asterias amurensis (Japanese seastar)", 2012; "Ocean Biogeographic Information System", 2012; Byrne, et al., 1997; Stevens, 2012), Northern Pacific sea stars live in estuarine, intertidal, and coastal zones and prey on other marine inhabitants in or on the substrate. offspring are produced in more than one group (litters, clutches, etc.) nov., a marine bacterium isolated from the starfish Asterias amurensis. This species reproduces seasonally and spawns during the months of January to April in Japan and during the months of June to October in Russia and Australia. 1996). The seastar is considered a serious pest of native marine organisms. We conducted a field experiment to compare the individual and com-bined effects of two introduced marine predators, the northern Pacific seastar Asterias amurensis and the European green crab Carcinus maenas, on a soft-sedi-ment invertebrate assemblage in Tasmania. Other habitat characteristics explaining P. fumatus abundance were depth, Asterias amurensis abundance, shell and macroalgae cover. These pests can compete with native species, alter habitat, reduce important fish stocks and potentially disrupt nitrogen cycling processes. 241: 99–112, 2002, Ross, J. D., Craig R. Johnson & Chad L. Because the seastar is well established and abundantly widespread, eradication is almost impossible. A row of spines from each arm come together near the mouth area, creating a fan-like appearance. However, they may occasionally be eaten by Japanese sun stars (Solaster paxillatus). We propose … Other articles where Asterias amurensis is discussed: sea star: …the Gulf of Mexico, and A. amurensis from the Bering Sea to Korea. In its native Japan, Solaster paxillatus (a sunstar) has been noted as a predator of Asterias amurensis (northern Pacific seastar). The National System for the Prevention and Management of Marine Pest Incursions. It was first described by Francis Jeffrey Bell in 1881 from a collection made before 1873 in Japanese waters. Females are capable of carrying about 10-25 million eggs. OBIS. Shah, F. and S. Surati 2013. 2012. In the upper shore, they are periodically exposed by the retreating tide, resulting in extended periods of desiccation. Northern Pacific Seastars are native to Japan, Korea and eastern Russia. BIODIVERSITY CONSERVATION AND HABITAT MANAGEMENT ... (Asterias amurensis) and Undaria seaweed in Australia, and the American comb jelly (Mnemiopsis leidyi) in the Black Sea. In insects, "incomplete metamorphosis" is when young animals are similar to adults and change gradually into the adult form, and "complete metamorphosis" is when there is a profound change between larval and adult forms. The larva begins to feed once the gastrovascular canals are formed, and at this stage is called a bipinnaria. Please consider upgrading your browser to the latest version or installing a new browser.

In their native Japan, they have devastated the shellfish industry. Information about this species has been distributed throughout coastal Australia to educate the community and encourage the reporting of sightings (, Poisons, such as quick lime, are available but are not specific to, Other possible control measures are being researched: for example, genetic manipulation, which involves inserting or changing genes which would eventually castrate the seastar and kill its young (, Changes in salinity were successful in laboratory experiments. The northern Pacific seastar Asterias amurensis Lütken was recently introduced to Tasmanian waters, possibly through ballast water discharged from ocean-going vessels. http://www.issg.org/database, Principal sources:NIMPIS 2010.

Mature ovaries are characterized by the constant release of eggs as well as their orange color. Taxon Information Most sea stars, including the Asterias rubens, may live in a variety of depths, including shallow shores to up to 200 fathoms. ("Introduced Marine Aquatic Invaders - A Feld Guide", 2012), Northern Pacific sea stars are not generally preyed upon by other organisms. Byrne, M., M. Morrice, B. Wolf. This process is all dependent upon the temperature of the water in which the sea star is developing; the warmer the water, the faster the rate of development. one non-native species at a time and have not addressed the interactive effects of multiple species.

"Asterias amurensis (Japanese seastar)" (On-line). This pest is sometimes confused with native species, but is distinguished by the arm tips and spines on the body. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. They prefer a slightly cold environment of about 7-10ºC; however, this species has adapted to the warmer waters of the Australian coast, which average about 22ºC. Each of these arms joins in the center of the organism to form a central disc. Customise filters (scroll to see full list) Taxon Oriental River Prawn - Macrobrachium nipponensis. native and introduced predatory seastars were compared in laboratory and field trials. Cohen., David R. The seastar is also considered a mariculture pest, settling on scallop longlines, spat bags, mussel and oyster lines and salmon cages (CSIRO, 2004). Accessed Asterias amurensis, also known as the Northern Pacific seastar and Japanese common starfish, is a seastar found in shallow seas and estuaries, native to the coasts of northern China, Korea, far eastern Russia, Japan, Alaska, the Aleutian Islands and British Columbia in Canada. The salinity range for this species is between 18.7 and 41ppt, while the maximum depth at which individuals have been found is 220m. More information about modern web browsers can be found at http://browsehappy.com/. It can have serious economic consequences for the aquaculture and fishing industries. In their native range they are known to go through 'bust and boom' cycles reaching high abundance and then rapid decline (NSW, 2007). Irregularly arranged spines run down the length of each arm.

Equichlamys bifrons was strongly associated with macroalgae and seagrass cover, whereas M. asperrima abundance was greatly explained by sponge cover. Population booms in Japan can affect the harvest of mari… The ADW Team gratefully acknowledges their support. Metamorphosis is induced by the detection of metamorphic inducing factors by the adhesive papillae on the brachiolar arms, such as chemical cues from adult sea stars in the environment. There is no home range information available for Northern Pacific sea stars. (Uscian, 2006), These sea stars exhibit positive phototactic behavior, moving toward light. The predation of A. amurensis by king crabs in Alaskan aquaria has also been observed ( NIMPIS, 2002 ). Reproduces in large numbers, reaching ‘plague’ proportions rapidly in invaded environments. Asterias rubens occurs on the English and North European coasts, A. vulgaris is found on the North Atlantic coast of North America, A. forbesi occurs on the eastern sea shore from the Maine to the Gulf of Mexico, A. amurensis is found in the Behring sea, Japan and Korea, and A. tenera occurs on the sea shore from Nova Scotia to New Jersey.
