Freshwater treatment finished end of November which had a positive impact on gill health and mortalities.
Hydrolicer permanently stationed in Loch Fyne with targeted treatments administered.
Treatments with Salmosan and freshwater 26/10/2020 to 2/112020, good clearance achieved. slice and hydrolicer also been used this year.
Some fish observed lethargic in the pens but could not be removed due to startle response. Some fish with physical damage also observed, attempts were made to remove these but also could not be caught. Site manager reported that any moribund fish are removed as soon as is possible with the pen surface checked when removing mortalities. [Original PDF]

Mortalities between 2020 WK35 and 2020 WK48 were caused by PD and AGD combined. Fish were treated with fresh water which brought down mortalities. These were reported to the FHI at the time.
Sea lice - 1.18 AF 2020 wk38 Sea lice levels remained under the CoGP recommended intervention level, with the exception of
WK38, which had 1.18 AF recorded. Hydrolicer was onsite soon after and numbers reduced.
Seal pro nets will be installed next year, tensioning of nets has been increased, although there are limited issues with predation on site.
Cleaner fish Mortality - 9233 since input. Majority of fish were "black losses" due to fish dying, but not being recovered in mort basket.
