Mortalities above 1% since input:
18/5 - 11.01% - Human error during wellboat treatment which resulted in low oxygen levels causing mass mortality.
24/08 - 1.47% - Post-treatment losses
05/10 - 2.94% - Post-treatment losses
12/10 - 8.07% - Post-treatment losses
26/10 - 1.11% - Post-treatment losses
Live haul harvests taken to Arnish processing plant.
Very few moribunds observed across the site. Few fish hanging around the surface and those that were had recently been passed through the hydrolicer. Majority of fish were sitting deep in the water so difficult to observe.
Hydrolicer was on site during inspection. Site began treating last week and are expecting to be finished by the end of this week. Manager reporting good clearance of lice; ~93%.
Divers were also on site during inspection checking the nets for damage.
Fish for VMD appeared healthy and had a good feeding response.

At most recent input 4 pens of KLM stock were lost. Failed smolt transfer. wk 35 - 7044 - 1.8% (2021) - Post input period.

Fish had been fed quite well before the visit, Fish feeding very deeply so was unable to catch for VMD sampling.
Some fish were observed and seemed in good condition and no clinical signs of disease were observed.

Site inspection and paper work conducted by , supervised by .
F1 sampled by , F2 - F4 sampled by and supervised by .
The site was visited in response to prolonged elevated mortality caused by an early spring plankton bloom causing gill irritation and anaemia. Visibility was good on the date of inspection, with fish feeding deep. A number of lethargic fish were observed across the entire pen group. Pens 2, 8 and 16 displayed the highest number of visibly lethargic and moribund fish, fish from these pens were selected for diagnostic sampling.
The site experienced mass mortality due to input failure at the beginning of the cycle with their KLM stock upon first input, the site lost 4 cages totalling >200,000 fish. Input mortality of KLM stock attributed to Tenacibaculum and a poor feeding response.
Following the input failure of the KLM stock, the site restocked with 550,000 fish from Loch Lochy in early August 2021. This stock is currently still held onsite although mortality for the cycle has been in excess of 60%, most of this mortality attributed to gill health issues suffered from an early spring plankton bloom. The site has conducted 6 slice treatments this cycle with a withdrawal of 500 degree days. Last slice treatment dated 22/06/2022, with all pens being treated over a 7 day period. Daily plankton trawls are conducted onsite, nothing significant has been dected this cycle but it is thought that a plankton bloom occurred and passed through the site in late April 2022 during the night. Around this time high levels of plankton were identified at Scotasay (nearby site within 4 miles).
Mortalities are removed onsite using a mort uplift system and the waste is taken by white shore cockels for landfill. The site employed the Backiness for mort removal between 28th June - 16th July 2022, waste was ensiled on the boat.
