Optimal oxygen for better fish performance

Consistent oxygen supports healthier, faster-growing fish in every system

Dissolved oxygen is the single most important parameter in aquaculture. Whether producers operate flow-through tanks or advanced RAS, maintaining the right oxygen level is essential for healthy, fast-growing fish.

Even moderate drops in oxygen can reduce appetite, slow growth and increase the risk of disease. Studies have shown that species like Atlantic halibut and channel catfish raised in well-oxygenated water gain more weight and require significantly less feed per kilogram produced. This means fish reach market size faster while using fewer resources.

Profitability and sustainability go hand in hand

For producers, the impact on profitability is clear. Feed is often the largest production expense, sometimes accounting for up to 70% of total costs. Improving feed conversion through precise oxygen management translates directly into better margins and more predictable performance. It also helps farms reduce water and energy use per kilo harvested.

OxyGuard has been helping fish farmers achieve this for more than 35 years. OxyGuard’s monitoring and control systems are designed to keep oxygen levels consistent and optimal, 24 hours a day. Automated adjustments respond instantly to changes in biomass, temperature or feeding activity. That means producers can rely on stable conditions without constant manual checks.

Better oxygen management also supports sustainability by reducing waste and improving animal welfare.
