Inspection reports

Case Number: 2020-0425

Download Lumpfish imported from Ireland (Bantry Marine Research Station) - One input this year in February.
Salmon came onto site from Barcaldine in two inputs over 2 days in December 2019.
Fish are transported live haul to South Shian processing plant for harvesting.
Average female leps rose above the CoGP threshold for treatment in weeks 39 and 40 (4.77 and 1.06 respetively). Hydrolicer was brought onto site in wk39 and numbers reduced the following week, with numbers below the threshold for treatment by wk
41.
Mortalities across the site were above 1% in wk38 and wk39, attributed to environmental insult in combination with gill health issues. These were reported. Mortalities reduced the following week and have remained below 1% since.
The site operates with a risk-based seasonal approach to gill health, taking gill swabs every week from 10 fish per cage.
Thermolicer treatment carried out in w/b 12/10.
One motality observed across the site. Fish were sitting deep in the water so difficult to observe, but when observed on the camera, appeared healthy and exhibited good shoaling behaviour and feeding response.
Fish sampled for VMD appeared healthy. [Original PDF]

Wrasse had not been imported since the last inspection and are not planning to do so in the future.
The wrasse have been wild caught in the Sound of Mull and were input onto site in October 2021, prior to the the input of salmon. The wrasse have been not been very active, nor feeding very well. In addition they are found very deep in the pen.
These observations have been attributed to colder temperatures.
Harvests are live haul using wellboats. In terms of the wrasse, Solway Transport is used for transfers.
Salmon were transferred onto site in October 2021. The stock origin is Barcaldine Smolt Unit (FS1328).

Case Number: 2022-0066

Download A previous site inspection was scheduled for the 22/03/2022, but due to bad weather was cancelled. Therefore, a REG case was assigned (2022-0021). All the paperwork was collected for that case on 17/02/2022. A new date was set to reschedule the cancelled site inspection; paperwork dating back to the 17/02/2022 was collected prior to the new inspection date on the
30/03/2022. Therefore, case 2022-0066 depicts the data collected from the 17/02/2022 to the 22/03/2022.
The recent low level mortality has been attributed mostly to predation from seals. Indirect affects of seal predation are seen through mortality attributed to physical damage.
Wrasse mortality has been very low. Wrasse were input onto site prior to salmon in October 2021. The wrasse have been feeding and swimming deep. From week 7 to 11, no wrasse mortalities were recorded.
Site thermometer used as inspectors thermometer did not work.
