Fish Health Inspectorate: sea lice information

To ensure the Scottish aquaculture industry continue to demonstrate satisfactory measures are in place for the prevention, control and reduction of sea lice on farm sites, Aquaculture Production Businesses (APB) are required to report weekly average adult female sea lice numbers when a specified reporting level is reached. The actual number should be reported at least a week in arrears or sooner and shall include the information required in the sea lice notification form. 

Information held relating to the reporting regime, is obtained by Marine Scotland, either through industry reporting or via Fish Health Inspectorate (FHI) surveillance.  This is used by the FHI to help assess whether satisfactory measures are in place in relation to the prevention control or reduction of sea lice (Lepeophtheirus salmonis). Information is actively published on a monthly basis, one month in arrears.

The following limitations must be considered in relation to the published information:

  1. The information presented is not a comprehensive record of sea lice data but details situations where the weekly average adult female sea lice levels per fish are at or above the reporting level*, as reported by industry or where information has been obtained through FHI surveillance.

  2. The information relates to a live spreadsheet and therefore may be subject to change at any point. Changes may not be easily recognisable between published versions and may be ‘historical’. The information is only an accurate record at the point in which information extraction occurred.

  3. In line with the current surveillance regime data older than 3 years (on a calendar year basis) will be archived and not expected to be subject to further change.

  4. Where information refers to treatment activity, this can reflect both actual and planned treatments. In relation to planned treatments these may or may not have taken place.
