Download Sealice treatment aboard well boat (Ronja Superior, 22/06/2020) Azasure, whole site treated but only cage 6 had increased mortality attributed to this. Fish were held for 3.5 hours. 13,699 atttributed purely to treatment in cage 6. Fish did not react well to treatment, maybe due to stressful sweep and CO2 levels was slightly higher in well reportedly caused by worsening weather conditions. Fish in well appeared blue and stressed on discharge. Mortality was increased in 3 days post treatment then returned to background level. Fish health manager took samples and tested for CMS and HSMI, both results came back as negative.
Cages 1 and 4 treated with Azasure in fully enclosed tarpaulins and cage 5 treated with Azasure on well boat. Lice treatments only undertaken on these cages as adult female lice numbers were not so high on others cages
New thermolicer to arrive at start of new year. It will operate all around Scotland.
Some caligus on site but very few Leps.
Slice treatments synchronised with other site in the area. Bath treatments not synchronised
Treatment intiated on individual cages once the lice count hits average of 0.01 adults females per fish.
Currently no AMA in place as regional manager recently left and there was no body to conduct meetings between the two companies. In the meantime Greig and SSF have written up FMS's and are willingly sharing those between each other. Once new regional manager starts a new AMA will be drawn up. Reportedly, sealice data currently shared with Grieg on a weekly basis.
10-15 metre lice skirts on at moment. Reportedly more effective at reducing lep numbers than caligus.

Site inspection and sampling by
No issues noted on site, fish shoaling well and fish sampled for VMD appeared healthy.
Site reported that plankton levels have been lower so far this year and gill health has been good so far. Smolts reportedly came in from Barcaldine ~200g.
SSF have implemented a very low trigger level for sea lice, 0.01, 100 fish counted per cage per week, trigger is 1 adult female for a cage. Treatments are targetted to specific cages that reach the treatment level. [Original PDF]

Download Remote inspection and physical site inspection conducted by , supervised by .
The site was recently stocked with fish transferred from Holmes Geo, very little mortality has occurred since input and the fish appear to be doing well. All epidemiological units were inspected onsite with no clinical signs of disease observed. Fish appear to be in good health, shoaling well and were observed responding positively to feed.
Animal health survalleince conducted by the companies fish health biologist, last carried out on 01/08/2022.
