Inspection reports

Case Number: 2021-0484

Fish came onto site in December 2020 from the Barcaldine Smolt Unit.
Site had a Salmosan treatment in June, a thermolicer treatment was done in July, peroxide in September and Slice towards the end of September, beginning of October 21.
Fish were sitting deep in the water, but those osberved appeared to be healthy and were active. Lots of wrasse observed in the cages which also appeared to be in good health. 8,791 wrasse were input over June, July and August 21 and only 190 mortalities have been recorded since then. Site manager reported their effectiveness in keeping lice numbers low.
1 mortality was observed across the site. This was removed at the time of inspection.
Fish sampled for VMD appeared healthy and demonstrated a strong feed response. [Original PDF]

Fish came on from Barcaldine (a mix of Aquagen Elite and Aquagen). Both stocks are reportedly performing well. A small number of moribunds were observed across the site but no other clinical signs of disease were observed so not removed for diagnostic sampling.
One cage of farmed lumpfish were transferred onto site from Fishnish (A), but staff struggled to remove them and were all lost during a 12hr FW treatment. APHA have been informed. Wild caught wrasse from around Orkney, Oban and Skye were stocked onto the site over several inputs in June, July, August and September and have been performing well. ~300 mortalities have occurred since input.
Slice treatment was completed in December 2022, January, February and March 2023. A FW treatment was done in May, the thermolicer was on site in June and July and a course of Aquatet was completed in September. Fish were vaccinated against
IPN and Furunculosis while in the FW hatchery.
Biomass on site is higher than preferred. Due to the water temperature dropping significantly in the weeks following the
Aquatet treatment, the withdrawal period for the Oxytretracyline may exceed 55 days. The fish have been sampled for residues and the site is awaiting results. If the fish have withdrawn from the treatment then the site will be passive graded and 9 harvests will occur between now and the new year to reduce biomass on site.
Average adult female leps combined above reporting threshold:
WK18 23: 0.63, WK20 23: 1.39, WK25: 2.56, WK28: 0.55, WK29: 1.56, WK31: 1.25, WK32: 1.14, WK33: 1.2, WK34:1.1,
WK35: 1.61, WK37:0.76, WK38: 1.78, WK39: 1.6, WK40: 1.2, 43: 1.9, WK44: 0.89.
AGD diagnosed on site and levels are remaining at moderate level.
Fish were removed from feed for a prolonged period during the summer months under veterinary instruction due to increased levels of jellyfish experienced on site
VHP, FMS and BMP all state mortalities are getting incinerated on the site barge, however, mortalities from this site and
Fishnish A are both being transferred in mort tubs back to a common skip at the shorebase before being uplifted by Billy Bowie and taken to Barkip for ensiling.
Tricaine was recorded in treatment record when Optomease was used.
Site staff informed inspector during visit that a seal had entered one of the cages on site recently. This had not been reported to the FHI as required and a retrospective notification was requested. With this said, the site was inspected as satifactory in terms of containment at the time of inspection.
