1.38% mortality during wk16 5753. Transfer and handling mortalities. There were fish being transferred from Euhglim FS1233 on the 06-07/03 and 21/03. Transfer and handling caused some scaling and physical damage of the fish. Some of the pens at
FS1233 were needing to be thinned down, so fish were brought over to harvest at this site as well,.

Routine health checks still being carried out on the fish, no significant results noted during period checked.
Sea lice level have been up and down and reports have been sent for those weeks which were over two. The last report was sent in February 2020 week 5 when ongoing storms meant they couldn’t get access to the farms. The last 4 weeks have been

PSI conducted following reports of high morts on site.
Mortality was low and slowly increased wk31 0.3%, wk32 0.22%, wk33 0.73% then wk34 2.34%. Then a freshwater treatment wk 34 reduced to 0.75% in wk 35 and health improved until wk38 4.87% and wk 39 10.67%.
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 stocked Jan 2021.
Sea lice numbers were low, gradual increase week 27 to31 but below coGP then over 3 af week 32 and 33. FW treat week 34 and hydrolicer wk 35. Thermolicer wk 38. Hydrolicer planned wk42.

Vuia Mor completed its stocking in February 2023 for the current production cycle, two stocks of SAL currently make up the site including 2022 Q4 fish from Applcross Smolt Unit and 2023 Q1 fish from Geocrab Hatchery. The site suffered some mortality of their 2022 Q4 stock initially post transfer onto site however very little mortality to their salmon stocks have been observed since.
The last internal fish health visit on 10/05/2023 noted some mild scoring for AGD and PGD, the salmon stock is otherwise healthy and developing well.
The site sustained some high mortality to their Lumpfish stock between weeks 9 and 15 of 2023. Two lumpfish were sampled on 06/03/2023 and signs consistent with a severe systemic bacterial infection were detected in both fish. Bacterial morphology and distribution were suspicious of Pseudomonas anguilliseptica. The companies fish health biologist at the time advised the site to cull any lumpfish which were displaying any such clinical signs of the disease. From weeks 16 to present lumpfish mortality onsite has greatly reduced.
During the physical inspection of the site only a few individuals of Lumpfish were clearly observed across the site and no clinical signs of disease were observed. Some lumpfish were also observed on camera and no clinical signs of disease were observed in these stocks. The salmon stock onsite appeared healthy during the inspection, fish were observed shoaling and responding positively to routine feeding regimes. 8 fish were removed for VMD sampling and all fish sampled were healthy externally and internally.
Lumpfish mortality (Last 4 weeks) - Week 19 (191, 1.53%), Week 18 (409, 3.18%), Week 17 (466, 3.5%), Week 16 (590,
4.24%).
During the inspection of the site, two small holes (2x1 square and 2x2 square) were observed just above the water line at pen three, these were pointed out to staff and repaired immediately. A further two holes (4x3 square and 3x5 square) were observed in pen 12, one slightly above the waterline and one on the waterline which were also pointed out to site staff and repaired immediately. The site were unsure on how this damage to their nets has occurred, site staff inspect their nets visually on a daily basis as part of their daily site checks of their equipment and facilities with no damage being reported on the previous day. The site is currently undergoing routine net washing and it is possible that this damage may have occurred during these procedures. The site intend to employ divers to check the site for any further damage. [Original PDF]
