Risk Based
Identify risk factors and
understanding for disease
emergence, introduction and
spread
Critical interventions stopping
disease transmission
Epidemiological control
• Dispersal models
• Risks to wild fish
• Defining aquaculture
management areas for integrated
disease control
Withdrawal of fish
• 3 to 6 weeks
Epizootic investigation
• All live fish movements and
other contacts over 12 months
back from 2 January ‘09
• No movements of live fish for
ongrowing outside South West
Shetland containment area after
mid June
• None outside Shetland
• All movements investigated
and spread ruled out through
inspection or testing
• Processing plants
• Biosecure and effluent
disinfection
• Supply of smolts from
freshwater
– Negligible risk
Site descriptions:
Pink = suspect
Blue = tested negative
Orange = PCR positive
Purple = confirmed or sequenced
