Salish Sea Marine Survival Project researchers investigated treatment methods to kill waterborne Nanophyetus salmincola parasites. Diluted formalin was most effective at killing parasites, with 100% mortality within 30 minutes; high concentrations of hydrogen peroxide and seawater produced 80%+ mortality in 10 minutes to an hour. These treatment methods provide useful options to prevent parasite infections in salmon and steelhead in high-risk salmonid enhancement facilities. Read more: Hershberger et al.
