This Sea star is an imported species from china, Japan, Korea and around Canada. The seastar is considered a serious pest of native marine organisms. Free-swimming larvae of the seastar found their way into the ballast waters and since introduction, the species has massively thrown off the trophic web in the reef ecosystem.

Sea star, any marine invertebrate of the class Asteroidea (phylum Echinodermata) having rays, or arms, surrounding an indistinct central disk. The everted stomach slips into the shell of prey and digestive enzymes are released in order to digest the soft parts of the prey. This species is an invasive species just like the Crown-of-thorns starfish. The undersides are completely yellow and arms are unevenly covered with small, jagged-edged spines (CSIRO, 2004). This study compared the individual and combined effects of two introduced marine species in SE Tasmania - the northern Pacific seastar (Asterias amurensis) and the European green crab (Carcinus maenas) - and investigated their impact on native invertebrate fauna using in situ caging experiments. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control.

The Northern Pacific Seastar, known in the seaworld as Asterias Amurensis, is better known as a “starfish.” While starfish is its popular name, this creature isn’t really fishy at all. It is a highly fecund subtidal species that can undergo massive population growth under optimal environmental conditions. It is a potential threat to the biological diversity of shallow-water marine communities, and could cause significant problems for the mariculture industry and temperate wild fisheries. This Sea star is an imported species from china, Japan, Korea and around Canada. Most seastars were caught within the first 24-48 hours and larger individuals dominated catches. The Northern Pacific sea star hitched a ride to southern Australia in ship ballast waters; it has since devastated marine ecosystems, costing millions of dollars to local fisheries. Organisms that compete with A. amurensis include: Uniophora granifera, Coscinasterias muricata and Odobenus rosmarus divergens (Pacific walruses) (NIMPIS, 2002). However, prevention and control measures are being implemented to stop the species from establishing in new waters. It was probably introduced into Australia through ballast water from Japan. The Northern Pacific Seastar is an interesting little marine creature. The seastar is unusual in being one of very few seastars worldwide that brood their eggs then give birth to live young (viviparous).
