Site inspected to carry out escape investigation and enhanced containment inspection, following incident which may have given rise to the risk of escape occurring when FHI last inspected the site on 04/12/2019.
Site has been experiencing increased seal predation over the last few months, new ADD system has recently been installed on site, subsequently mortalities attributed to seal damage have reduced over the past month.
During inspection 1-2 lethargic fish were observed in the majority of cages. In cage 4 several lethargic fish with lesions visible on the flanks were observed. % fish were removed for diagnostic sampling. The remaining lethargic fish observed on site were removed from the cages and dispatched.
Fish sampled for VMD appeared healthy.
Escape investigation
During a the previous FHI inspection on 04/12/2019, a seal was observed in cage 5, the seal was then seen to leave the cage.
Divers arrived on site the same day to inspect the cage and net and discovered a hole near the base of net, approximately
25x15 mesh squares in size (nets on site have a mesh size of 15 mm). The hole was repaired by the divers. It is suspected that the hole was caused either by seal damage, or possibly by the lift-up system cone rubbing against the net during recent storm conditions Dive reports indicate that fish were observed to higher up the water column in the cage, no fish were observed outside the cage, and in the following days feed levels had not dropped. The APB completed and submitted the escape notification form to the FHI on the same day, noting that it was suspected that no fish escaped during the incident.
Divers returned to site on 06/12/2019 to inspect all other cages on site, no damage or holes in nets were found, all support ropes for lift up systems were tightened. Prior to the escape, divers inspected cages and nets on 29/11/2019 with no holes or damage observed.
At the time of the escape the site had an OTAK A.D.D. system on installed on site. Following the incident frequencies on the
A.D.D. were adjusted and an additional A.D.D. system (Ace Aquatec) has been installed on site, with both systems running.
Mortality attributed to deal damage have fallen since.
Nets on site are currently STAR mesh, these are due to be replaced with Seal pro nets at the end of this production cycle. Seal pro nets are currently being installed on the neighbouring Vuia Mor site. [Original PDF]

Site last inspected on 26/02/20. CNA, escape investigation and diagnostic carried out
13/4/19-19/4/20 1.8% Seal Predation 2615 lumps on site sourced from Wales.
Currently site undergoing a mechanical sea lice treatment (brushes) and reported to be going well with low mortality levels so far and 88% clearance. Lice levels had been 1.8 adult female prior to treatment. Planning a mechanical treatment every 2 weeks. Site under harvest plan with June as planned harvest out date.
Seal predation has been an issue, both common and grey seals. Two types of ADD on site and seal blind for dead socks. Two seals have been dispatched but in the last 10 days the seals have disappeared from the area. They have been unable to get
Seal Pro nets but will be getting them for the next cycle. Morts attributed to seal predation have seal damage lesions.
Morts in the last 10 days 20/4/20-29/4/20 is 2173 (0.98%) attributed to post treatment and seal damage.

, shadowed by .
Site carried out Slice treatment from 11/03-17/03/2021 and 13/05-19/05/2021.
Seal Pro nets now deployed at site with company also looking to raise height of nets (~0.5/1m) to aid in prevention of seals gaining access to pens. Electric fence has been installed on one pen to deter seals from accessing walkways. Installation of the fence has shown early signs of detering seals.
Mortalities:
Weekly mortality rates, weeks beginnning 18/01/21 (wk3) 7501 (1.67%) and 25/01/21 (wk 4) 7184 (1.62%) reported to FHI.
Explained reason was seals. Mortality levels dropped below reporting criteria on week 5 and have remained below since then.
No moribund/ lethargic fish spotted. Stock on site remaining low in water so hard to observe
Fish sample for VMD appeared healthy- internally and externally. [Original PDF]

PSI conducted following reports of high mortalities during August and September. Site was due to be visited in wk37 but could not be due to covid19 isolation of site staff.
Mortality rates low across site 0.04% in week 31, 0.23% in wk 32 up to 3.99% in wk 33 and 5% wk 34. FW treatment in wk 34.
Mortality reduced following FW treatment but increased again following handling for sea lice treatment week36/37.
Routine visits of health biologist to sites every 2 weeks in Summer, regular haematocrit and gill swabs taken but quick onset of anaemia and some AGD which seems to have been exarcebated by a plankton/jellyfish environmental event. However, daily water samples haven't shown anything conclusive although water cloudy and full of sediment. Water quality is poor and low rainfall over summer months also. During this period aeration of water has been on 24/7.
Site was stocked in Dec 2020.

Kyles Vuia completed stocking for its current production cycle in December 2022 with stock from Kinlochmoidart and Jubilee
Loch Shin. The Salmon stock have performed well so far this cycle with good growth being achieved and mortality onsite remaining very low.
From the physical inspection of the stock, fish were observed shoaling well and responding positively to hand feeding at the pen side. No clinical signs of disease were observed onsite during the inspection. Fish sampled for VMD appeared healthy both internally and externally.
The site conducted its latest precautionary Slice treatment at the end of April which has been successful in maintaining low lice levels to date.
The site sustained high mortality to its lumpfish stock early in its current production cycle. Six lumpfish were sampled by the company vet on 23/01/2023 with all fish sampled showing pathology consistent with severe systemic bacterial septicaemia.
Following this diagnosis the descion was made to cull the remaining lumpfish stock on site. [Original PDF]
