Inspection reports

Case Number: 2020-0382

Download When fish were transferred from Teisti Geo to Holms Geo in August 11th 2020, a fire occurred on the well boat. The fire cut all power to the well boat and the wells could not be oxygenated. The fish could not be removed from the wells. This caused the death of 29,000 fish.
In the last cycle of fish 28,000 (19.08%) fish died in July 30th 2018. A crash in oxygen levels over night (reportedly due to a plankton die off) caused the death of 6,500 fish. The fish were immunocompromised due to CMS. Fish killed as a result of
CMS numbered 21,500 fish.
No sea lice treatments yet this cycle.
Caligus numbers on the way up, so SLICE has been ordered for the site and they will be treating using SLICE on the week of the physical inspection.
Caligus numbers elevated, but Lep numbers still very low.
Treatment intiated on individual cages once the lice count hits average of 0.01 adults females per fish. Bath treatments not synchronised between sites.
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.

Site inspection and sampling by
No issues noted on site, sea lice skirts not installed on site at present, may put these on, but this is still to be decided. Sea lice extremely low, with an extremely low trigger for treatment. 100 fish counted per cage per week and trigger is 0.01 adult female, treatments are being targeted to specific cages that reach the treatment level.
Hoping to get another site manager in to share management of the sites, after the promotion of previous site manager. weather changeable during the inspection. [Original PDF]

Download At time of inspection net washer was present due to this there was a slight increase of fouling on site.
General population of fish were shoaling as expected, responded to external stimuli and had a good feed response. On average 3 deformities were observed per pen, but responded to stimuli.
There has been an increase in jellyfish numbers across the site.

Download The site was stocked in February 2026, with all fish originating from the same source (Girlsta Hatchery, FS0504).
Mortality levels have remained low throughout the production cycle, with no instances of elevated mortality at either site or pen level.
Fish observed during the inspection were shoaling well and remained deep within the water column. No lethargic or moribund fish were observed. Three fish with spinal deformities were noted; however, all were swimming normally and responding appropriately.
The site manager reported that a small number of fish had been identified during routine health checks as having shortened opercula. As this condition was also observed at the hatchery, it is considered likely to be of genetic origin. At present, the condition does not appear to be adversely affecting fish performance, as demonstrated by the consistently low mortality levels.
One of the fish removed for VMD sampling had slightly shortened opercula, although evidence of new growth was observed.
Fish removed for VMD sampling were in good condition both externally and internally upon examination, with no significant abnormalities noted.
The site is scheduled to be fallowed in 2027. Production is rotated between 3 sites within area, with next production cycle being Teisti Geo (FS1093) in 2027. [Original PDF]
