UV Systems for Aquaculture
The lifeblood of today’s aquaculture industry is the water used to incubate fish eggs and rear juvenile fish
Water abundance and purity continue to decline while disease concerns found in source waters continue to increase. Simultaneously, increased consumption of fish has led to growing demands for higher stock densities in the same hatchery footprint.
Fish hatcheries and rearing facilities are evaluating ways to improve the quality of their source water, while offsetting quantity losses through implementation of recirculating water systems.
This is leading more fish hatcheries to install sophisticated water treatment systems to enhance water qualtiy, reduce the possibility of disease outbreaks due to pathogens, and balance water needs due to the lack of available water from natural sources.
Aquafine UV Systems are perfect for use in:
- Fish Hatcheries
- Incubation, rehabilitation facilities
- Depuration facilities
- Processing Plants
- Influent/effluent treatment

Located on the Klamath River in Hornbrook, California, Iron Gate Hatchery is a salmon and steelhead hatchery that releases fish back to the Klamath River. Due to the presence of the fungus Saprolegnia sp and primarily bacteria (Flavobacterium psychrophila and Metallogenium sp), hatchery yield is thwarted due to disease.

Ultraviolet (UV) light disinfection systems play an important role in a complete water treatment process in aquaculture facilities.
UV Applications in Aquaculture
- Disinfection – the most common application of UV in water treatment. UV systems significantly reduce pathogen counts in incubation and rearing facilities and have proven to be the most cost-effective disinfection technology for the inactivation of many types of bacteria, viruses and parasites harmful to many species of fish.
- Ozone Destruction – ozone is often used in a fish hatchery to enhance the quality of problematic water sources used for incubating and rearing fish. However, residual ozone in the water can be extremely toxic or fatal to the aquatic life being reared. UV light systems are applied to consume the residual ozone in the bulk water prior to contacting the fish.
