Case paperwork completed by on 24/11/2020.
Fish brought on site week 44, 2020. Morts collected and transported to Shetland for disposal.
VMD sampling by 26/11/20. Fish sampled at pier next to shorebase due to company H&S COVID-19 policy and concerns regarding movement from a higher tier to lower tier. Fish brought ashore by site staff, all fish appeared healthy. Site inspection re-scheduled for 2021 Q1. No issues reported on site. [Original PDF]

One fish removed for VMD sampling. Fish appeared healthy and in very good condition, sampled by .
Site has experienced low level sea lice numbers and currently undergoing third SLICE treatment of cycle, no sea lice observed on fish sampled for VMD. Very good visibility at time of inspection and population showed good shoaling behaviour
All new equipment on site for start of cycle last year, site very well maintained. Site staff reported a higher than normal level of growth on nets, due to net washer currently awaiting a part from Norway. A net wash company will be employed until part arrives. Site staff also reported that the top 2m of the net were worst for growth, due to very good visibility at the time of inspection the nets could be observed deeper in the water with much less growth.
The site may receive stock directly for next cycle rather than a split of fish from another site.
Good biosecurity on site, with foot mat used between pens and disinfectant sprayer to spray down oil skins and boots between sites. [Original PDF]

Fish came on from Barcaldine and have been performing well this cycle.
Thermolicer was on site at the time of inspection.
2 Slice and 2 peroxide treatments done at the end of 2022. Azasure completed in December 22 and only thermolicer, freshwater and AMX done in 2023.
Management area is not fallowed synchronously on a single year class basis. Risk assessment has been developed. This was inspected and found to be adequate.
Background CMS and HSMI have been detected on the site but are not causing mortalities.
Fish on site appeared in good health and were actively shoaling in the cages. <5 moribunds were observed across the site and were removed during the inspection and humanely culled. No clinical signs of disease were observed so diagnostic samples were not taken on this occassion. ~12 mortalities were also noted across the site but were not fresh dead.
Fish removed for VMD sampling appeared in good external and internal health and demonstrated a strong feed response.
Very few lice were observed on the fish at the time of inspection. [Original PDF]
