6 Biosecurity
6.1 Animal source

Animals should be obtained from disease-free farms or sources only, after
appropriate health testing and disease-free certification by a reputable veterinary
laboratory; disinfect eggs or larvae where appropriate, quarantine (isolate) all animal
introductions from the rest of the farm for an appropriate period of time. The length of
quarantine time depends on the species of aquatic animal and potential disease or
parasite. Contact DPI&F veterinary and extension officers for advice.
b) Seek advice on appropriate preventative treatments for parasites to all introduced
animals while still in quarantine.

6.2 Hygiene

a) Seek advice on the disinfection of eggs or larvae prior to use.
b) Remove sick and dying animals as soon as possible and treat in a quarantine
section or dispose of appropriately, so there is no contamination of the farm animals
or aquatic environment.
