Scotland's freshwater fish are protected by legislation including the Diseases of Fish Acts 1937 and 1983. This requires fish farmers, ghillies, District Salmon Fishery Boards and Fishery Trusts, to report the symptoms of fish diseases to the Fish Health Inspectorate.
Notifiable Diseases in Fish
These diseases are notifiable in all species of fish.
Notifiable Diseases in Shellfish
- Bonamiosis
- Haplosploridiosis
- Iridovirosis
- Marteiliosis
- Mikrocytosis
- Perkinosis
Disease Categories
Annex A of Council Directive 91/67/EEC classifies notifiable diseases into three categories. Each category has its own set of restrictions. This is to regulate disease control and to ensure the safe movement of fish and the placement of aquaculture products on the market.
List I Diseases: List I diseases are exotic to the European Community, and would have severe economic consequences for farmed and wild fish stocks were they to occur.
List II Diseases: List II diseases are present in some parts of the European Community but are exotic to Great Britain. List II diseases can cause great financial difficulty for fish farmers.

List III diseases: List III diseases are present in the European Community. There are no community wide control measures for List III diseases but Member States may have a national control policy. They may also result in financial losses.
Furunculosis and IPN are not currently controlled in Great Britain.
Special Controls
Specific control measures are applied to fish farms where the presence of the List I and List II diseases ISA, VHS or IHN is suspected or confirmed. These measures are laid down in EU legislation under Council Directive 93/53/EC. This legislation is implemented in Great Britain under The Diseases of Fish Control Regulations 1994.
Restrictions on movements of live fish suspected or confirmed as being infected with a notifiable disease are controlled under notices (Thirty Day Notice) or by Order (Designated Area Order) made under The Diseases of Fish Acts 1937 and 1983. |
