Catalase, Liquid

PeroxAway™

PeroxAway™ neutralizes residual hydrogen peroxide (H2O2) after treatment of cage-cultured salmon for sea lice and other diseases and after RAS biofilter disinfection. It’s highly active even in high-salinity and low-temperature conditions.   

Also available in 200kg and 25kg pack size.

Key Benefits Description
  • Helps protect the marine environment

    At high concentrations, hydrogen peroxide can pose a risk to the marine environment by negatively impacting non-target species. Your customers can use PeroxAway™ to break hydrogen peroxide down into harmless oxygen and water before release into open seas. That helps reduce the impact of H2O2 on the environment after its job is done. 

  • Temperature- and salinity-tolerant

    The natural conditions for optimal salmon farming are challenging for some enzymatic products. In Chile, Norway, Scotland, Canada and other key farming regions, water temperatures range from 5°C to 14°C (46°F to 57°F). PeroxAway™ is highly temperature- and salinity-tolerant. It has been shown to be highly active in conditions where temperatures are as cold as 4°C and salinities are as high as 35ppt.  That means it’s robust enough to keep working in the cold and salty conditions typical of salmon farming. 

  • Highly active, highly effective

    Due to its concentration of catalase, PeroxAway™ is highly active. That makes it highly effective at bringing residual hydrogen peroxide levels down to a point that’s safer for marine life.  

  • Easy to implement

    PeroxAway™ is a drop-in solution that you can easily fit into your operations. Simply mix  PeroxAway™ slowly into the sea cage after your standard H2O2 treatment protocol. It’s then broken down by the enzyme before release into the open sea.     

  • A more sustainable solution

    PeroxAway™ is biodegradable and renewable. That makes it a more sustainable solution, benefitting both salmon farms and for the wider marine environment. 

Outbreaks of sea lice (Lepeophtheirus salmonis) can not only make farmed salmon unmarketable, but also negatively impact fish welfare, making a hard job even harder. Salmon farms may choose hydrogen peroxide (H2O2) - which is also effective against amoebic gill disease - as a management strategy. But high levels of H2O2 released into the marine environment can pose a serious risk to non-target species.

PeroxAway™ splits hydrogen peroxide into harmless water (H2O) and oxygen (O2). That gives salmon farms all the benefits of hydrogen peroxide while reducing their impact on the marine environment.

How catalases break down H2O2 to support more sustainable fish farming

Many fish farms use H2O2 (hydrogen peroxide) to manage parasites and disease, but discharges can harm marine life. Catalases render H2O2 harmless by splitting it into water and oxygen.


Scarring from sea lice (Lepeophtheirus salmonis) can make farmed salmon unmarketable. Farms use H2O2 (hydrogen peroxide) to treat amoebic gill disease and sea lice. Sea lice attach to their salmon hosts by suction. When hydrogen peroxide is introduced to the water, it causes a reaction that releases gas bubbles in the tissues of the louse. These damage and weaken it, causing it to release its hold on its host.

This treatment results in discharges of residual hydrogen peroxide to the marine environment. If concentrations are high enough, these discharges can put other, non-target species at risk. Salmon farms can treat the residual hydrogen peroxide with catalase. That results in the discharge of harmless oxygen and water instead. In this way, catalases bring residual hydrogen peroxide concentrations down to levels that are safer for marine life. That benefits the marine environment and helps salmon farms be more sustainable.
