Notes"Report Submitted to the Western Regional Panel on Aquatic Nuisance Species, U.S. Fish and Wildlife Service." "While S. quoianum has not spread to these new areas, ... the populations in Yaquina Bay appear to have expanded since 2005. S. quoianum was found in 42% (21/50) of surveyed sites in Yaquina Bay and some sites hosted very high densities of the isopod... In addition, S. quoianum is now potentially impacting the local economy of Yaquina Bay: Oregon Oyster replaced their dock floats recently and nearly every one of the 60 one-meter long newly removed Styrofoam billets were riddled with S. quoianum burrows..." (p.10) Includes photographs of damaged floats at Oregon Oyster Farms on Yaquina Bay.
