As Infectious Salmon Anaemia continues to spread around the world - with recent cases in Norway and Canada and suspected for the first time in Iceland - a Freedom of Information reply published online by the Scottish Government on 3 November 2021 reveals that 7% of Scottish farmed salmon sampled between 2002 and 2012 tested positive for Infectious Salmon Anaemia. That's 396 ISA positives out of 5,395 samples.
"Infectious Salmon Anaemia has been lurking on salmon farms in Scotland for over twenty years," said Don Staniford of Scottish Salmon Watch who today wrote to Scottish Ministers. "In view of the increasing spread of ISA in Norway, Canada and now in Iceland, the Scottish Government must close the border to imports of salmon eggs (ova). Peer-reviewed science has shown that ISA can spread to farmed salmon via infected ova - so-called vertical transmission. Importing tens of millions of ova from Iceland, Ireland and Norway to on-grow on 'Scottish' salmon farms represents an unacceptable risk to biodiversity and biosecurity. In order to protect the genetic integrity of Scotland's iconic Atlantic salmon, all farmed salmon including ova and smolts should be screened for ISA, Piscine Reovirus and other viruses, diseases and pathogens. The positive case of ISA virus at Scottish Sea Farms in Loch Spelve in May 2021 could be just the tip of a very large iceberg."
"The ISA virus is a ticking time-bomb with the risk of spreading the deadly disease all too real. RSPCA Assured @scotseafarms in Loch Spelve could be ground zero in another ISA disease outbreak" https://t.co/d0hFOve4pg @scotgov @SSPOsays @rspcaassured @obantimes @scotgp pic.twitter.com/JguXT9RgkG

Scottish Salmon Watch has now asked the Scottish Government to disclose collated data from 2013 to 2021 (the Scottish Government's FOI disclosure refuses to provide a breakdown of ISA cases since 2012) which includes an ISA positive case from Scottish Sea Farms in Loch Spelve reported in May 2021.

Others companies operating in Scotland such as Cooke Aquaculture, Grieg Seafood and Mowi are experiencing ISA problems at their salmon farming operations in Norway and Canada.

The FOI disclosure was published online by the Scottish Government on 3 November 2021:
An Excel spreadsheet was posted online by the Scottish Government via FOI - 202100234467 - Information Released - Annex - including 396 positive tests for ISA out of 5,395 samples (that's 7%):
Here's a summary by year:
And here's a summary of the results from various ISA tests:
A Marine Scotland 'topic sheet' published in 2016 provides more information on the diagnosis of ISA:

Dear Don
I refer to your response to my clarification request concerning FoI 202100234467 regarding the subject area of infectious salmon anaemia (ISA) virus. As you have confirmed we will include ova within the subject area of point 2.
You failed to respond to two specific parts of the clarification I sent to you. Specifically:
- A timescale associated with point 1 – in the absence of any communication from you on this I will assume this to be from the date the request was received back to the start of the year 2002.
- The specific details associated with the request for ‘details of any extended surveillance of Scottish salmon farms for the ISA virus’ – in the absence of this I will handle this part of your request only in relation to the example you have given (amended to include the subject area of ova) - For example, how many samples of farmed salmon (in both hatcheries and sea farms) have been tested annually by the Scottish Government since 2002 and how many samples of farmed salmon have tested positive for ISA (including both HPR0 ISAV and HPR-deleted ISAV)?
I have attached the clarification communication and your response to the same, for your reference in relation to the points referred to within this email.
If your request goes beyond my interpretation, as detailed above, then you must tell me specifically the information you require.
Thank you.
Neil

Subject: ISA in Scottish Farmed Salmon - letter to Scottish Ministers & FOI request
To: <[email protected]>
Cc: Gougeon M (Mairi), MSP <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, Burgess A (Ariane), MSP <[email protected]>, Ruskell M (Mark), MSP <[email protected]>, MSP <[email protected]>, Beamish C (Claudia), MSP <[email protected]>, Mountain E (Edward), MSP <[email protected]>
Further to the positive test for Infectious Salmon Anaemia Virus at Scottish Sea Farms in Loch Spelve in May (as reported by the Scottish Government's Fish Health Inspectorate via 'Case Information' published online earlier this month) what action is the Scottish Government taking to stop the spread of deadly ISA? What other salmon farms are affected and how many other positive cases have been detected?
This is believed to be the first time ISA has been publicly reported in Scotland since an outbreak at Norwegian-owned Scottish Sea Farms and Grieg Seafood in Shetland in 2009. In 1998-9, an ISA outbreak in mainland Scotland (traced back to Scottish Sea Farms – formerly known as Hydro Seafoods GSP – in Loch Nevis and then spreading to Loch Creran, the Sound of Mull, Loch Linnhe, Kerrera, Lismore, Shuna and Loch Spelve) cost £100 and led to the loss of 200 jobs.
Please provide data on the number of positive results for ISA (including both HPR0 ISAV and HPR-deleted ISAV) in farmed salmon in hatcheries and sea farms as well as imported and domestically produced ova. Please detail any actions being taken by the Scottish Government to deal with the ISA problem in Scotland.
Please note the recommendations of a report published by the Royal Society of Edinburgh in 2002 in the wake of the 1998-9 ISA outbreak in Scotland:
Please therefore provide details of any “extended surveillance of Scottish salmon farms for the ISA virus”. For example, how many samples of farmed salmon (in both hatcheries and sea farms) have been tested annually by the Scottish Government since 2002 and how many samples of farmed salmon have tested positive for ISA (including both HPR0 ISAV and HPR-deleted ISAV)?
If the “extended surveillance of Scottish salmon farms for the ISA virus” failed to materialize please provide information on any testing by salmon farming companies including Scottish Sea Farms, Mowi, The Scottish Salmon Company, Grieg Seafood, Cooke, Loch Duart and Organic Sea Harvest (the foreign owned/controlled companies who together account for 99% of ‘Scottish’ salmon farming production).
Please also provide information on any scientific studies into the spread of ISA and the presence of ISA (both HPR0 ISAV and HPR-deleted ISAV) in farmed salmon in Scotland. Please note that the authors of a 2017 scientific paper – “First field evidence of the evolution from a non-virulent HPR0 to a virulent HPR-deleted infectious salmon anaemia virus” – conducted the experiments in Aberdeen at Marine Scotland Science.
Please consider this an official request for information under the relevant FOI and Environmental Information regulations.
