Each tank is a defined biological zone
We minimise the risk of infection being transferred to other tanks in the farm by making each of them a defined biological zone. In other words, fish and water in one tank are not shared with other tanks.
One tank corresponds to a single biosecure space. That reduces of the risk of pathogens establishing an internal strain in the tank environment, and being transferred between tanks.
Separate fish tanks make it easier to clean and disinfect them when fish are to be moved within the farm.
In addition to increasing biological security, this reduces complexity in the facility, makes it simpler to service, and minimises the risk of consequential technical errors
