Contacted company for further information, site was treated with the optilicer but due to underlying CMS some pens had increased mortality. Mortality rate is now reducing. FHI to monitor following weeks mortality rate. Site was inspected 3/12/19
(case 20190715) and elevated mortalities were recorded also following optilicer treatment.
09/03/2020 15/03/2020 3.5 kg 1.59% Treatments/CMS 9079

Post-treatment losses following optilicer treatment w/b 2nd March 2020. Contacted site for further information. Full scale harvest will begin next week (30/03/2020), specifically targeting pens with larger fish and where CMS is causing higher mortalities. This will be reviewed in 2-3 weeks’ time by site management staff. FHI to monitor mortality levels in the coming weeks.
23/03/2020 29/03/2020 3.6kg 2.79% CMS 14387
Harvests started Contacted site manager. Harvest began yesterday. Harvests are restricted due to factory through put and
COVID19 situation but plan to harvest 3-4 times a week. Mortalities still continuing from the treatments at beginning of the month and CMS (very low CT values ).
30/03/2020 05/04/2020 3.6kg 1.88% CMS 9220
Site manager contacted previously. Harvests underway. Starting 30/3/20 and planned for 3-4 times per week. Combination of
CMS and harvest mortalities.
06/04/2020 12/04/2020 3.6 kg 2.8% CMS 12,816 -PSI to be conducted
Morts slightly down so far this week; 3000 for last 5 days.
Treatments since last visit; 23/2/20- 5/3/20 Optilicer , 14/12/19-22/12/19 peroxide/salmosan in wellboat, 16/4/20 salmosan tarp treatment of the Girlsta fish.
Harvesting ongoing 2-3 harvests per week, limited by COVID19 situation only allowing 10000 tonnes a load but now accepting
15000 tonnes per load. Next week 3 harvests scheduled.
Three stocks on site, Landcatch in two pens, Kames in 6 pens and Girlsta in 2 pens. Grilsta input were later stocked and are smaller average wt (2.6kg). Girlsta fish appear not to be as badly effected by CMS and it is hope these will remain on site until
October. Target harvesting the Landcatch fish currently.
The 2 Girlsta pens were given a salmosan tarp treatment yesterday and it appears to have gone well with little mortalities in these pens. No mechanical treatments planned for the site due to CMS. Lice levels have been kept low with company treatment triggers of 0.8 average female.

Mortalities removed daily by staff and monitor fish using cameras in cages. Divers on site monthly to conduct net checks.
SLICE treatments of current cycle in April (5-11th), May (16-22nd) and July (11-17th). Plan to undertake hydrogen peroxide tarp treatment for AGD in August.
Take daily water samples (Monday-Friday) to monitor plankton. Samples sent to lab in Lerwick.
All stocks on site from Barcaldine, but a variety of ova sources (Fanad, Aquagen and Benchmark).
