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]
