Download Case paperwork completed by on 14/10/2020, Inspection by on 20/10/2020
PD (SAV 5) reported in stock earlier in the year but not causing issues some AGD treated with peroxide
Mortality event had not been reported earlier in the year as site contact thought only unexplained events were to be reported.
2020, week 30 1.95% 1,322 Ardessie A, AGD treatment with peroxide resulted in increased morts, background PD considered a contributing factor.
Mortality data collected for the Ardessie B site during the inspection, 2020 week 30 Ardessie B 2.68% 3417 AGD treatment with peroxide resulted in increased morts, background PD considered a contributing factor.
Site inspected and VMD sampled by - Fish looked health and feeding well. Very little fouling on nets. A few mature fish spotted but no health concerns observed. [Original PDF]

Case Number: 2021-0330


Download Following the mortalities due to gill health issues and handling for husbandry operations, there has been a return to normal mortality, with fish shoaling as normal and no moribund fish observed. The site has planned to start harvesting from the end of this week. A seal was observed close to the pens but predator mitigation was in place. Lions mane jellyfish observed on site.
Records show observed cleanerfish mortality is very low. Nets are kept clean by swim-through and air drying. Although registered separately, the two Ardessie sites are operated as one for production purposes. Inspection and remote paperwork undertaken by supervised by [Original PDF]

Case Number: 2024-0069


Download Site originally received an input of fish from Corry Farm in May/June 22 after a fallow period, but these fish have been harvested. Fish left on site originally came through Lochailort hatchery, Loch Arkaig before coming onto site in Dec 22 from
Loch Torridon for their 2nd sea winter. The site manager reported that they have been performing well since input. Site experienced elevated mortality over the winter months, attributed to maturation.
Fish will be graded beginning of April to separate the population into harvest fish and broodstock. Production fish are scheduled to be harvested in the summer, when the selected broodstock will be moved to a FW site (potentially Elphin or
Inverpolly, TBC (Update 29/08/24: application to stock broodstock at Inverpolly was received 08/07/24)) later in the year. The site will have a fallow period before fish on neighbouring Ardessie B will be split between the two sites and ongrown. Neither of the FW hatchery sites are currently authorised to hold broodstock. This was discussed with the site manager and the business correspondent is aware that an authorisation amendment application will need to be submitted prior to any movements occurring.
Company biologist generally visits the site each month. Fish were positive for CMS, HSMI and Yersinia in Feb 24, but these are not causing elevated mortalities.
Site (CoGP MA 10d) was already stocked with fish from Corry Farm (MA 10b) when fish from Loch Torridon (MA 11a) were received. Neighbouring site, Ardessie B, also received an input of fish from Loch Duich (MA 14a). As a result, the MA has been stocked with multi yearclass fish from more than one MA. This should only occur for broodstock or harvesting purposes and the broodstock farm should be at least 5km or one tidal excursion (whichever is greatest) from another farm, harvesting station or processing plant. Ardessie A is situated within one tidal excursion and within 5km of Ardessie B. An authorisation amendment application was received on 16/10/23 and this is being dealt with separately.
Wrasse mortality since input: 66%
Lumpfish mortality since input: 86%
