FW treatment scheduled for wk 38/39. FHI to monitor. Update 22/09/2022 AZM: waterbourne insult from premused microjellies 4 weeks ago. AGD escalated quickly since then with necrosis on gills. Trial pens treated with 6hr FW and settled mortality and amoeba reduced. Therefore all pens on site treated with FW. Weekly health visits have occurred since insult began. Low level PRV on site but not clinically expressed. Some physical wounds from handling and low level Tenacibaculum diagnosed. Histology has not revealed any bacterial infection.

Due to the on going Covid-19 situation a remote inspection was completed on the 12/11/2020. A physical inspection of the stock was planned for the following week, however due to weather conditions ferry transportation to the Isle of Arran was
Cancelled and the visit had to be postponed.
WRS less than 10% since input. [Original PDF]

Records checked between 12/11/20 to 21/12/20 as had checked records in case 20200507 upto the 12/11/20 although site visit could not be conducted due to ferry cancellation and will be rescheduled in 2021.
PSI conducted following reports of increased boat traffic in area from 3rd party.
AGD and PGD on site - due to gill health problems in previous cycles, gills are swabbed weekly so can act quickly - FW treat in
September with good results and then treated with peroxide once temp down to 10c 29th Nov-2nd Dec following this treatment morts decreased to low levels
Morts wk47 - 0.54%, wk48 0.59%, wk49 1.81%, wk50 0.17%, wk 51 0.12%

Morts transported by Billy Bowie
WK 34 (FW Treatment, 2894 (0.62%) WK35 22,048 (6.22%), WK 36 35,108, (10.56%) WK37 - 36,959 12.34%.
2 different stocks on site, mortality consistent across the site.
Main issue on site has been gill health challenges, with one health report suggesting anaemia as well. Fresh water treatments have been conducted 20/08 9/10, 5/10/2022. Mortality has dropped after these, however it has risen again shortly afterwards.
Gills show moderate pathology, comprising lamellar inflammation, epithelial proliferation and vascular disturbances. Lesions are suggestive of a combination of factors, including infectious (Desmozoon lepeophtherii, Ca. Branchiomonas cysticola) and non-infectious (environment, handling) insults. No amoebae are detected, but some of the hyperplastic lesions present may reflect previous amoebic gill disease pathology.
Mild to moderate inflammatory pathology is noted in the heart sample; changes are suggestive of a viral infection, possibly piscine reovirus (PRV). eDNA samples are currently being processed to find out which organisms are present in the water.
Very few (1-2) moribund fish observed. Fish which appeared externally healthy were seen congregating around air diffusers.
These would frighten and scatter when approached. [Original PDF]

Peaks in mortality above reporting threshold: 2023, wk 18 3139 (1.92%) wk 19 2909 (2.04%), wk 22 757 (4.68%), wk 24 566

(10.31%). week 34 (to date), 3098 (4.05%).
Site received additional stock from Sgeir Dughall in Feb/March, Maaey in May and Geasgill in July. Site was fallowed for 10 days prior to the Geasgill input. Gill issues have been the main issue.
Recent health report details that AGD scores were low, PGD scoring between 1-3, with moderate gill damage noted.
Peaks in mortality 2022 wk 43 3018 (1.61%), wk 44 4869 (2.63%), wk 45 9330 (5.18%), wk 46 5514 (3.23%), gill health the main cause but some external lesions were reported.
Recent treatments have been the FW FLS (15/8/2023) system only which has been effective for lice control.
On inspection of stocks two moribunds were observed however these were too deep in the water column to remove, a number of lethargic fish were observed five were selected and removed for diagnostic sampling.
Wrasse mortalities for the last four weeks: wk 31 0, wk 32 14 (0.59%), wk 33 32 (1.35%) and wk 34 7 (0.30). [Original PDF]

Fish came on from Applecross and performed poorly in the first 2-3 weeks following transfer. However, have been performing really well since with low mortality and low lice numbers observed across the site. SLICE was administered in December 23 as a prophylactic and no further treatments have been conducted since. Last crop were FW treated in combination with FLS which resulted in good clearance.
Sealice counts:
Site stocked in wk50 2023. No lice counts have been above the CoGP treatment threshold since input. Previous crop went above the CoGP treatment threshold for a couple of weeks but numbers quickly reduced following FW and FLS treatments.
Company biologists attend the site every fortnight to take routine swabs and bloods. Additional samples are only taken if there are concerns regarding fish health.
Divers attend the site monthly to conduct sub-surface inspections of nets and moorings. Site has access to its own net washer so nets are also visually inspected every 10 days.
Fish on site were sitting deep in the water on the day of inspection so were difficult to observe. 1 mortality was noted across the site and no moribunds were observed in any of the cages. Box nets were deployed to catch fish for VMD sampling. The fish that were observed in the box nets were in excellent body condition. Gills appeared healthy and no lice were observed on the fish removed for sampling. [Original PDF]
