Download Site currently in the process of harvesting. Hope to have this complete by late March. Sea lice levels have been above reporting level the last few weeks and physical treatment has been carried out during breaks in the bad weather of late. Fish behaving as per expected and look to be in good condition. Fish removed for VMD sampling inspected and looked healthy internally with no signs of disease and no physical damage externally.

Download Fish on site appearing in good condition and all shoaling as in normal behaviour. Less than 1 lethargic fish per pen. Fish removed for vmd appeared in good condition with no signs of disease upon internal examination. First input onto site on
29/03/2023 and there has only been 2,246 mortalities removed across the whole site since input. There was a slice treatment on 17/05/2023 but only 4 pens were treated. [Original PDF]

Case Number: 2025-0394

Download Mortality levels started to increase significantly at end of last week. Fish health reports indicate the presence of AGD (low CT values and gill damage observed). Two dive teams on site during inspection to remove mortalities.
A freshwater treatment is planned to start as soon as possible on Sunday once the weather improves. The treatment boat has two wells and will be able to treat fish from two pens simultaneously. Treatment time is 8 hours so should be able to treat 4 pens per day.
The site was recently stocked with wild wrasse caught in Shetland. Creels have been placed in the pens to remove as many wrasse as possible before the planned treatment. There is an unstocked pen on the site and the wrasse will be held there temporarily. Mortality levels in wrasse since input have been low.
Sea lice treatments carried out in August (freshwater) and end September/early October (thermolicer). Thermolicer treatment reduced average female Lep count from 4.12 (week 39) to 0.87 (week 40). Average female Lep count had increased to 1.85 in week 42. During inspection approximately 40-50 fish per pen were observed with lice damage to the head area, some severe.
Five fish were removed for diagnostic sampling. All had high lice loads and evidence of sea lice damage to the head (fish 4 was severe). Fish also had evidence of poor gill health such as white patches and pale gills. Internally all had pale livers, three had yellow faecal casts and two had slightly grey kidneys. [Original PDF]
