Scottish Aquaculture Industry - BackgroundMain Species Farmed• Atlantic salmon• Rainbow trout• Blue mussel• Pacific oyster
• Atlantic halibut, brown / sea trout, Arctic charr
• European oyster
Scottish Aquaculture Industry - Background• Salmon (freshwater) – 105 sites, 36.9 million smolts• Salmon (seawater) – 254 sites, 144,159 tonnes• Rainbow trout (freshwater) – 31sites, 4,145 tonnes • Rainbow trout (seawater) – 8 sites, 2,620 tonnes
• Other Species – 34 sites, 389.5 tonnes• Blue mussel – 59 businesses, 6,477 tonnes • Pacific oyster – 30 sites, 2.9 million• European oyster – 1 site, 490, 000
Scottish Aquaculture Legislation
• Aquaculture and Fisheries (Scotland) Act 2007– Control of parasites
– Control of escapes
– Improved record keeping
– Access to records by inspectors
– Powers of enforcement
PARASITE
Sea lice Regulation
Industry Requirements– Satisfactory measures – control
prevention and reduction
– Legislative requirements – ‘2008 Record Keeping Order’
– Industry Code of Good Practice
Industry Code of Good Practice– weekly counts 25 fish (5 fish from 5 cages)
– suggested trigger 0.5 (Feb-June) 1 (July-Jan) Ls adult female
– management agreements
– appropriate training – good practice in the use of medicinal
products
Sea lice regulation
Record Keeping – training – lice counts – administration of medicinal products – methods to control /treat parasites – sea lice management groups
Inspections and audits of fish farm sites– Inspection – sea lice & treatment records;
inspection of stock– Enhanced inspection – all records;
inspection of stock, checks of sea lice counting procedure; treatment, administration.
– Enforcement action
Containment Regulation
Industry Requirements• Satisfactory measures – contain fish, prevent
escapes and recover escaped fish
• Legislative requirements – ‘2008 Record Keeping Order’
• Industry Code of Good Practice
Industry Code of Good Practice• Equipment specification, installation
• to meet manufacturers advice
• Net inspection and testing
• Fish transfer and handling
• Actions to take following escape
• Boat operations
Containment regulation
Record Keeping• Specification of equipment and facilities
• Training – boat handling, transfer and handling fish
• Risk assessments – fish transfer and predation
• Contingency plans for escapes
• Flood prevention measures for inland water sites
• Record of severe weather events damaging equipment, action taken
Inspections of fish farm sites• Inspection – escape events? Inspection
to check site integrity
• Enhanced inspection - of all records; inspection for site integrity; escapes investigation; audit of procedures. Enforcement action
Scottish Aquaculture Legislation• Aquatic Animal Health (Scotland) Regulations 2009
– Implements Commission Directive 2006/88/EC
– Authorise and register businesses
– Attach conditions to the operation of authorised businesses• Record keeping• Biosecurity• Surveillance requirements – including risk based
– Notification and control of listed diseases
– Certification of trade – import and export
– Provision of a publicly available list of authorised businesses and sites.

Scottish Aquaculture Legislation
• Commission Regulation (EC)1251/2008– Implements Council Directive 2006/88/EC as regards conditions and
certification requirements for the placing on the market and the import into the Community of aquaculture animals and products thereof and laying down a list of vector species.
– Controls imports of fish from other member states and countries outside the EU
– Lays down the certification requirements for trade to other member states and countries outside the EU
BACTERIA
Status in Scotland, selected listed diseasesDisease Susceptible species Status
Epizootic Haematopoietic Necrosis
Rainbow trout Category I (disease free)
Infectious Salmon Anaemia
Salmonid sps. Category I, except targeted surveillance in SW SH, Cat IV
Infectious Haematopoietic Necrosis
Atlantic salmon, RTR Category I
Viral Haemorrhagic Septicaemia
Trout, herring etc. Category I
White spot disease Decapod crustaceans
National sampling strategy, III
OsHV-1 var, emerging
Pacific Oyster Cat II, Surveillance prog.
Bacterial Kidney Disease
Salmonid sps Cat V, infected. National controls.
Efficient Surveillance
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

Site descriptions:
Pink = suspectBlue = tested negativeOrange = PCR positivePurple = confirmed or sequenced
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
