Sea lice counts and treatments applied, by farms, by week: EIR release

Information request and response under the Environmental Information (Scotland) Regulations 2004.

FOI reference: FOI/18/03408  
Date received: 16 November 2018
Date responded: 17 December 2018
Information requested


All data held within Marine Scotland, or which it has received, for 2018 year to date, which shows sea lice counts and treatments applied, by individual farms, week by week.



As the information you have requested is ‘environmental information’ for the purposes of the Environmental Information (Scotland) Regulations 2004 (EIRs), we are required to deal with your request under those Regulations.  We are applying the exemption at section 39(2) of the Freedom of Information (Scotland) Act 2002 (FOISA), so that we do not also have to deal with your request under FOISA.

This exemption is subject to the ‘public interest test’.  Therefore, taking account of all the circumstances of this case, we have considered if the public interest in disclosing the information outweighs the public interest in applying the exemption.  We have found that, on balance, the public interest lies in favour of upholding the exemption, because there is no public interest in dealing with the same request under two different regimes.  This is essentially a technical point and has no material effect on the outcome of your request.

Please find the attached information which is relevant to your request.

In addition to the attached spreadsheet, there may be some additional information obtained through the aquatic animal health surveillance activitiy undertaken by the Fish Health Inspectorate. The results of this activity are published quarterly, three months in arrears as part of an active publication plan. You can find further details and the results of that surveillance (which may contain additional information to your request) at the following Marine Scotland web page:
