Inspection reports

Case Number: 2020-0035


Download PSI carried out following notification from business of increased mortality attributed to gill damage resulting from an algal bloom. CMS and AGD also present in stock.
Aeration system in place to mitigate against algal bloom. Feeding has been reduced.
Wrasse wild caught from Hebrides, Lumpfish from Ocean Matters, Anglesey
Site first stocked in April 2020 from neighbouring site Stulaigh (FS1259)
Remaining 3 cages to be stocked from Marulaig Bay (FS0865) in next few weeks.
Freshwater treatment carried out when fish first stocked and four weeks subsequently, to treat AGD. [Original PDF]

Case Number: 2022-0093


Download Fish came on from Loch Lochy. Successful transfer with low mortalities.
Slice treatment completed at the end of February and had good clearance. Visual gill scores were at ~0.05 in March.
Fish were sitting deep in the water but those that could be observed appeaered to be in good condition and were shoaling nicely.
Fish sampled for VMD appeared healthy externally and internally. [Original PDF]

Case Number: 2024-0154


Download Stock transferred onto site from Kingairloch (Loch Ness, Aquagen ova) in January and March 2024. Site was fallow for 6 months prior to transfer. Delayed input due to plankton in the area in October 2023, risk assessment completed for transfer between management areas. Salmon split into Marulaig Bay in May.
Lumpfish on site from Ocean Matters. Received first batch of locally wild caught ballan wrasse on 31 May (input into pen 7 with large grade as no lumpfish in this pen). Expect to input more wrasse to increase percentage stocked to ~2%.
Strategic treatment of fish with SLICE in April 2024. Freshwater treatment in May 2024 due to poor gill health.
Main cause of salmon mortalities is poor gill health and poor performers. Main mortality cause in lumpfish is Tenacibaculum
(three cages of lumpfish treated with florfenicol post delivery). Mortalities are removed daily using Foover and sent to
Whiteshore Cockles for disposal.
Two weekly mortality events above threshold not reported for previous cycle. In addition, the percentage for one weekly mortality event (wk 26 in 2023) was recorded incorrectly in the mortality event spreadsheet (reported correctly by company at the time). Corrected to 1.41%.
Fish feeding well, but had been on starve for 2 days due to presence of plankton. Approximately 1-3 floating dead fish seen in pens 1-6. Two moribunds removed from pen 1 plus two feeding fish from pen 1 for VMD, diagnostic samples taken from all fish. [Original PDF]
