Fish Farms & Aquaculture

In high-density aquaculture facilities, water quality directly determines production efficiency. Low dissolved oxygen, nitrite accumulation, and pathogen load threaten fish health and drive up antibiotic use.

Scientific data clearly demonstrates ozone's impact on RAS (Recirculating Aquaculture Systems): an ozone feed rate of 25–39 g ozone/kg feed reduces suspended solids (SS) load in RAS water by 35%, COD by 36%, and colour by 82% (Summerfelt et al., 1997; rainbow trout RAS study). In the same study, nitrite concentration within the culture tank decreased by 82%, and mortality and treatment requirements from bacterial gill disease (BGD) fell markedly. Ammonia can be reduced by 61% and nitrite by 78% (shrimp pre-feeding stage study, XINOZONE review). Turkey’s first integrated 50 Nm³/hour O₂ + 400 g/hour ozone aquaculture system was installed by OCS Ozone at the Gümüşdoğa Keban facility.
