Key Biosecurity Tasks
Biosecurity plays an important part throughout every stage of the life cycle of a fish, from hatching through to processing. Thorough cleaning is an essential precursor to any effective disinfection process to maximise the benefits of Virkon™ AQUATIC, the complementary Biosolve™ E heavy-duty cleaner should be used. The following table indicates the specific key biosecurity tasks which will have the greatest impact on controlling the spread of disease, see below for Biosolve™ E & Virkon™ AQUATIC application rates.
