As Recirculating Aquaculture Systems (RAS) continue to gain popularity worldwide, operators face persistent challenges—ranging from high mortality rates and reduced yields to viral and fungal outbreaks. While vaccines and chemical treatments like formalin are often used to manage these issues, they are typically reactive and can be costly over time.
A more proactive and sustainable solution is the use of ozone for water disinfection.
Ozone, though well-established in water treatment, is still underutilized in many aquaculture settings. With an exceptionally high oxidation potential (2.07 V), ozone is highly effective at neutralizing pathogens and improving overall water quality. For instance, a CT value of just 0.8 min-mg/L can achieve 99.99% removal of Aeromonas salmonicida—the bacterium responsible for Furunculosis.
A study conducted by Polytechnique Montréal at a commercial RAS brook trout farm demonstrated the following benefits of ozone integration:
- 1-log reduction in fungal microorganisms
- 65% reduction in suspended solids
- 38% reduction in BOD₅
- 60% increase in feed rate, resulting in significantly higher yields
- Zero mortality observed during the study period
These results clearly highlight the potential of ozone as a cost-effective, preventive strategy that not only improves fish health but also enhances system productivity.
If you’re looking to improve performance, reduce losses, and future-proof your RAS operations, ozone may be the solution you've been seeking.
