Fish came on from North Shore (FS1033)
Farmed lumpfish and wildcaught wrasse on site.
Mortalities and waste are stored in sealed bins on site until they are transferred to a common skip at the shorebase. The skip is collected by JD and taken to whiteshore cockles for landfill.
Mortality events:
Wk31: 5.3%, Wk45 (2019): 3.17%, Wk 44 (2019): 2.62%, Wk43 (2019): 3.64%), Wk42 (2019): 1.52%
Mortality events that occurred in 2019 were attributed to the presence of CGD, CMS and PD on site. The mortality event that occurred in August 2021 was post-treatment.
Average adult female leps increased to 2.21 in wk29 and the site responded with a FW treatment which had good clearance, reducing the count to 0.29 the following week. The average count increased to 5.78 in Wk33. A salmosan and thermolicer treatment reduced the count to 1.86 in wk34. An average count of 2.32 was recorded in wk35 but reduced to 0.29 in wk36 as a result of an ongoing thermal treatment. When the average adult females increased again to 2.17 in wk28, a hydrolicer treatment reduced the count to 1.18 in wl39.
Site is conducting live haul harvests to Mallaig processing plant.
New thermolicer was on site during inspection. This was the first site to be treated. If the clearance rate of sea lice is high, then the boat will move to North Shore.
No mortalities observed across the site and only 4 moribunds were noted.
Fish sampled for VMD appeared healthy and demonstrated a strong feed response. [Original PDF]

Input of fish from Loch Ness and Glenfinnan occurred in Sept 2022.
Slice was administered between 03/03/2023 to 12/04/2023. Therefore, on date of inspection fish were in withdrawal for Slice.
The end of the withdrawal period is expected to be 04/06/2023.
AGD has been an issue on site with currently ~ 20% of the site showing lesions. Many fish have outgrown their lesions and are coping weel with it. Freshwater treatments are planned for end May/June.
Seal interacions were an issue in December 2023 but since have decreased. Pens most affected were pen 9, 10 and 15. A seal was observed in pen 10 on 26/12/2022 during net washing. Bird net lifted and seal exited. Netwashing camera showed no holes in the net when checked and divers confirmed this on 27/12/2022. Notifications recieved on 25/05/2023 following discussion that this incident should have been reported previously in Decemeber 2022.
HSMI has been observed specifically in pen 3, 7, 8, 9 and 10.
Migdale Transport used for any transfers.
During the inspection of cleaner fish records, increased mortalities were observed in the wrasse population. From week 37 to
41 2022 , the site received weekly wrasse inputs of farmed and wild wrasse.  Simultaneously, elevated mortality was occurring following these inputs, with percentages between 1.34% and 5.65% observed.  Elevated mortality continued until week 10
2023, with average weekly mortality percentage at 6.66% and average weekly mortality count of 5334. Specifically, two spikes in mortality were noted; Wk 50 2022 with 19.75% (18681) and Wk 3 2023 with 19.68% (10099).  The cause of mortality was attributed to poor quality on input, with these morts being classed as ‘without diagnosis- fresh’ in mortality reports. To date, from week 37 2022, an approximate total of 133,119 wrasse have been lost from an input total of approximately 164,109. lumpfish onsite have been input onto site in April 202 from cleanerfish.
Recent Lumpfish mortality (2023):
Wk15- 0.14%, 51
Wk16- 1.68%, 602
Wk17- 1.28%, 452
WK18 - 1.85%, 645
Site inspection conducted on 16/05/2023. During site inspection very few moribund fish observed, with some fish seen swimming deeper with old and healing moritella lesions. These fish were out of reach and swimming behaviour was normal, therefore no fish were samples for diagnostic purposes. Fish removed for VMD sampling were in good and healthy condition.
Site is planning to move 4 pens from Tabhaigh to Scalpay on skye in summer 2023. [Original PDF]
