Trials have been run to find effective removal processes including physical removal of "A. amurensis", which was estimated by workshop participants to be the most effective, safe and politically attractive when compared with chemical or biological control processes. Several "sea star hunting days" have been organized in Tasmania in which several thousand sea stars have been removed. Mountfort "et al". studied developing a probe to test ballast water and detect the presence of this specific maritime pest. Early detection remains the best solution to reducing harmful effects of invasive species.
