Anytime seafood is cultured and farmed, it is crowded and they become stressed. Crowded conditions will degrade water quality and increase transmission of pathogens. Such stress decreases the immune response which in return renders them more susceptible to disease. This is a dangerous combination that can lead to disease and massive fish kills in all culture situations. In recirculation systems, fish are often crowded in traditional aquaculture and water quality can quickly change for the worse. One way to minimise disease outbreaks is to disinfect the system water using UV and Ozonation treatment.
What Is Biosecurity Concern in Aquaculture?
Biosecurity involves the practices, procedures and policies used to prevent the introduction and spread of disease-causing organisms (e.g., bacteria, viruses, fungi, parasites) as well as many aquatic invasive species (e.g., zebra mussels, rusty crayfish). Fish diseases continue to be one of the greatest causes of economic loss for the industry, accounting for millions of dollars in annual losses to fish producers. While some fish pathogens are well known problems, other diseases are emerging or spreading to previously unaffected areas. Outbreaks can happen rapidly and spread quickly, often resulting in high mortalities. It is difficult to predict when disease might occur, however the routine use of biosecurity measures can reduce the risk of introduction and economic impact of these diseases.
How UV & Ozonation Treatment Keeps Water Safe
They are a chemical-free method of water disinfection that uses ultraviolet light to inactivate harmful microorganisms, including bacteria, viruses, and parasites. UV systems work extremely well in recirculating aquaculture systems (RAS), where water reuse is critical.
Key benefits of UV treatment in aquaculture include:
- UV light neutralises pathogens without altering the chemical composition of water, ensuring a safe environment for aquatic organisms.
- UV systems do not produce harmful by-products, aligning with sustainable aquaculture practices.
- By reducing disease outbreaks, UV treatment supports healthier stock and higher yields.
For aquaculture businesses, investing in UV technology offers a pathway to improved water quality and long-term sustainability.
Another game-changing technology in water disinfection is ozonation. Ozone, a powerful oxidising agent, is introduced into the water to eliminate contaminants, break down organic waste, and improve water clarity.
Ozonation works well with UV treatment because it tackles other problems, like removing bad odours and improving water clarity. Together, these technologies create an optimal aquatic environment that promotes fish health and growth while minimising environmental impact.
