Aquaculture

The use of Ultraviolet disinfection systems in fish farms and hatcheries has lead to the production of healthier and larger fish as well as the possibility of an increase in stock densities without the increased risk of disease.

UV does not change the physical characteristics of the treated water so there are no undesirable side effects such as toxic by-products, pH changes or temperature fluctuations.

Organisms responsible for fish diseases that are treatable using a Hanovia UV disinfection systems:

• Viral haemorrhagic septicaemia (VHS)
• Infectious Salmon Anaemia (ISA)
• Saprolegenia (fungal disease)
• Infectious pancreatic necrosis (IPN)
• Coliform bacteria
• Ichtyophthirius (white spot disease)
• Faecal streptococci

Aquariums

In large aquariums containing expensive stocks of fish such as koi karps, UV is often used because there are no toxic by-products, pH changes or temperature fluctuations.
