Fish Deseases And Parasites

Scotland’s freshwater fish are protected by legilsation including the Diseases of Fish Acts 1937 and 1983. These Acts make it a legal requirement to notify the Ministers of the suspicion of the presence of certain diseases in all species of fish. These are known as NOTIFIABLE DISEASES. It is an offence not to report incidences of these fish diseases. In Scotland the Fisheries Research Services (FRS) act on behalf of the Scottish Ministers and if you suspect the presence of a Notifiable Disease or if you require more information please contact the Fish Health Inspectorate by telephone on or by email: .
