Poor gill health attributed to micro jellyfish- gill health improving.
Slice treatments carried out in August and this week (31/10/22). They have plans for salmosan tarp treatments, but the last two days the sea has been too rough to safely treat and they are standing by for a good weather gap
Site thermometer used for biosecurity reasons
Sea lice average adult female wk40 1.17; wk41 1.69, wk42 1.75, wk43 2.14
From health reports; primary cause of gill health challenge during this period starting August, and continues to be present today albeit in much lower concentrations. The main species identified is Muggeia atlantica, a hydrozoan species.
Dundas and Barkip for mort disposal final destination.
Mort level week 44 lower - 0.44% as divers were unavailable to work on site due to covid issues. Week 45 will be up over reporting as divers will be back on site but general gill health improved in larger fish but population of poor doers continues be cause increased mort levels.
Lethargic poor doers observed in pens but not moribund, Some dead fish observed in pens. Are all removed daily but had appeared in afternoon as divers not available to remove dead fish that have not ended up in the dead baskets.
Planned tarp salmosan treatment week 14/11/22 - 5 cages to do. Not being done this week due strong tides.
All processing done at Loch Duart in Dingwall - recorded in Harvest schedule reports. Destination not specified but all fish go to Dingwall and going forward will record destination. [Original PDF]

Mortality: increased mortality at the end of 2024 due to gill issues caused by environmental challenge.
Sealice: Elevated level at the end of 2022 treated with salmosan which reduced lice dramatically (2.7 to 0.2 adult female
Lep./fish). Current cycle of fish have had lower lice levels with a thermolicer treament used in November 2024 to bring slightly higher lice numbers back down.
All harvesting from the site is deadhaul.
Health Surveillance: Most recent report (22/01/2025) seen - some kidney samples tested positive for Tenacibaculum species.
No positive results for other pathogens such as furunculosis or piscirickettsia.
During the physical inspection of the site, 5 moribund fish were observed across the whole site. Harvesting was taking place from one pen and a fish was taken for VMD sampling from this pen. The fish taken for sampling appeared healthy both externally and internally. [Original PDF]
