Inspection reports

Case Number: 2021-0139


Download AGD was the biggest health challenge last cycle so gill swabs are being taken and analysed by PCR every 2 weeks.
Lumpfish arrived on site in October from Otter Ferry and were stocked at 6%. 4 lumpfish mortalities observed across the site, not fresh dead so no diagnostic samples taken. Lumpfish mortality for April was 7.2% attributed to handling.
Fish on site came from Inchmore and Loch Lochy and have been vaccinated against furunculosis and IPN.
Site doing live and deadhaul harvests. Harvest boat was on site during inspection.
Majority of fish were sitting deep in the water so were difficult to observe. A few fish were observed with physical damage but were not moribund or lethargic.
Fish sampled for VMD appeared healthy.
Paperwork inspected remotely 20/05/2021. Site inspection completed on 27/05/2021 [Original PDF]

Case Number: 2024-0139


Download WRS and LUM all farmed from Mowi owned farms
Cleaner fish treated with florfenicol in feed treatment since date of input (food from World of Feeds)
Moritella detected on site using PCR with high CT-values. Reportedly no clinical signs of the disease. No clinical signs of disease observed during inspection of the stock.
Pseudomonas anguiliseptica detected in lumpfish population via PCR with low CT-values. Higher than average lumpfish mortality has been attributed to this pathogen.
Fish caught for VMD samples appeared healthy externally and internally. [Original PDF]

Case Number: 2025-0068


Download Site inspection partially completed from the boat due to the adverse weather conditions. 5 out of 12 pens were inspected by wholly walking around the units. 2 moribund fish with physical damage on the head were observed during the inspection, the farm manager thinks the damage is due to the fish hitting the hamsterwheel at the centre of the cage.
The majority of the population could be observed deep in the pens. The fish sampled for the VMD appeared healthy both externally and internally.
Thermolicer treatment 17/02/25 - 22/02/25.
Pseudomonas outbreak in Lumpfish in July - October 2024. 26,900 fish lost in total during the period. Functional feed given to the lumpfish.
Handling during sea lice treatments (site uses dewatering system to separate the fish from the salmon) also causing high mortalities in cleanerfish - 16,000 LUM and 2,500 WRA lost in 2024.
A further 9,600 LUM and 13,500 WRA were lost in 2024 due to other transport/handling events. [Original PDF]

Case Number: 2025-0414


Download Fish transferred from Loch Shell (Caolas a deas) and Trilleachean Mhor in August.
Uplifts morts into bins and taken onto the Hordafor 3 (Pelagia) - waste transfer note inspected 04/11/2025 and taken to
Shetland for disposal. Fergusons used on 19/10/2025 - transfer note inspected.
Deadhaul harvest - to Mallaig or Blah Mhor
Pen 8+9 planned to be harvested out on 10/11/2025.
Last treatment was a FW + FLS from 17/10/2025 to 20/10/2025.
During the site inspection, between 25+ lethargic fish were observed in pen 8 and 9, with ~10 in all other pens. No noticeable lesions were observed during the site inspection, but some fish showed signs of healing lice damage on heads. Five moribund/lethargic fish removed and diagnostic samples taken.
Wrasse mortality (last 4 weeks): Wk44; 801, 3.59%;Wk 43, 947,3.48%; Wk42, 655,2.35%; Wk41,215,0.77%; Wk40, 645,
2.25%. No lumpfish in this production cycle.
Discrepancies in the mortality events was observed between what was notified to FHI and the records held by the site.
Specifically, Wk42 (notified of 26952, 9.72%; records show 17980, 6.47%) and WK41 (notified of 4355,1.55%; records show
3827 1.36%) 2025. Explanation was provided on the reasoning for these discrepancies: an amendment had been made as after counting the fish in the harvest tubs there was found to have been an overestimation of the mortality numbers.The site records are the correct and up to date figures. Updated notifications have been provided (12/11/2025). [Original PDF]
