Download Fish from Barcaldine (Aquagen) and Girlsta (Stofinfiskur)
Slice 27/5/22 - 02/06/22 all pens treated.
Potential use for cleaner fish but no plans to use them for this site in the near future
Seeing a lot of caligus at the moment but have treated previous rises recently with SLICE which has worked.
During on site inspection only 2 mortalities were observed on the whole site. Fish were deep in water but those observed looked healthy. A couple fish had lesions to the face which were potentially previously caused by net damage.
VMD samples taken from cages 3 and 7 by .
Mortality levels above reporting threshold from during July 2019 through to October due to CMS. Mortality levels again elevated the following cycle in late May 2021 to August due to gill health issues. All events were reported to FHI.
24/05/22 - 26/07/22 due to CMS but numbers never above reporting level.
