Stability of Hydrogen Peroxide in Aquaria as a Fish Disease Treatment

摘要

Hydrogen peroxide is increasingly being considered as a therapeutic compound in aquaculture. There is limited information regarding the decomposition rates of hydrogen peroxide under the environmental conditions found in production systems. Thus, thepurpose of these experiments was to determine the persistence of hydrogen peroxide under different environmental conditions. Our results indicate that in the presence of aeration and/or organic matter, hydrogen peroxide concentration decreases to below the level of detection within 48-72 hours. Under static water conditions in the absence of aeration and organic matter, hydrogen peroxide concentration decreased to approximately 50% of the original concentration by day 6 and persists decreased to 0 mg/Lby day 10. Information on the stability of hydrogen peroxide is essential to evaluate the toxicity of hydrogen peroxide to fish.
