It is often found in estuaries and on mud, sand or rocky sheltered areas of intertidal zones (CSIRO, 2004). Northern Pacific sea stars live in estuarine, intertidal, and coastal zones and prey on other marine inhabitants in or on the substrate. It is evident that several fisheries have been negatively impacted – there has been an estimated one billion dollar loss in the industry in Tasmania. It can have serious economic consequences for the aquaculture and fishing industries. 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. However, larval stages are free-swimming and are known to travel using water currents. It is a predator upon numerous shelled mollusk species, as well as other invertebrates of limited motility, and is also an opportunistic scavenger. In: Global Invasive Species Database (GISD), Auckland, New Zealand: University of Auckland. The larva begins to feed once the gastrovascular canals are formed, and at this stage is called a bipinnaria. The seastar is considered a serious pest of native marine organisms.

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). Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. In Abstracts: Second International Conference on Marine Bioinvasions, March 9-11, 2001. It is the second largest ocean in the world after the Pacific Ocean. This means that the sea star moves with a particular ray of its body in a certain direction and the rest of the organism slowly follows. This marks the transition of the larva into the brachiolaria state.

A row of spines from each arm come together near the mouth area, creating a fan-like appearance. National Control Plan for the Northern Pacific Seastar Asterias amurensis. They were first recorded in Australia from the Derwent Estuary, Tasmania in 1986. It is typically found in shallow waters of protected coasts and is not found on reefs or in areas with high wave action. The seastar will eat a wide range of prey and has the potential for ecological and economic harm in its introduced range.

Feeds on shellfish, including commercially valuable scallop,oyster and clam species. Introduced Marine Invaders, Northern Pacific Seastar. The northern Pacific seastar is a voracious feeder, preferring mussels, scallops and clams. Introduced predators such as A. amurensis, are likely to have large impacts on native communities this is because, besides being a direct competitor for resources to native seastar species, it is a voracious generalist predator in soft-sediment habitats which consumes a wide variety of prey according to the ecological availability of prey (1, 8). the body of water between Africa, Europe, the southern ocean (above 60 degrees south latitude), and the western hemisphere.

Ross J and Johnson C (1998) Invasiveness and impact of the northern Pacific seastars Asterias amurensis on natural communities in SE Tasmania. 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.
