Company biologist contacted. Site was fallow in September but has since been restocked with larger fish, mostly from Ardgadden and Strondoir Bay. PGD combined with a mechanical treatment accounted for a majority of the mortality. Also, fish are maturing earlier than usual which are dying due to poor weather and treatments. Mortality rate is reportedly reducing on site. FHI to monitor

Case Number: 2020-0355


Download Cleaner fish from Ocean Matters. About 6,000 LUM lost since input. 723 lost on the week of transfer. Mortality increased from background mortality to 892 per week in the last month. Wk 34: 892, wk 33: 809, wk 32: 654, wk 31: 404. FVG and company biologist have been on site and taken samples but everything has come back as inconclusive so far. Thought to be bacterial.
Cleaner fish supervisor will visit the site the day after the remote inspection. Mortality of cleaner fish has reduced in the last week.
Hydrolicer on site 24/08/2020 treated 3 cages. Hydrolicer recommencing treatments on day of the remote inspection after being stormed off the day before. 85-90% lice removal on Monday.
Four SLICE treatments in the cycle so far. 14/10/2019 - 23/10/2019 (prophylactic), 16/12/19 - 22/12/19, 02/03/20 - 08/03/20,
18/05/20 - 24/05/20. Successful treatments and synchronised with other site in the loch.
Bird nets, tensioned nets, seal blinds, ADD's, contract with Rentokil for shorebase.
Patogen took gill swabs to check for the presence of AGD on 30/07/2020. 12 fish sampled, 6 fish came back as positive.
Reportedly no clinical signs associated with AGD on site.
Hydrolicer treatment taking place while on site, increased mortality for the duration of these treatments.
VMD fish appeared healthy when sampled

Download Cleanerfish on site are from Otter Ferry. The farmed ballan wrasse were introduced onto site w/b 23/05/2022, with only 5 pens stocked. Remaining pens will be stocked with wrasse in June 2022. Lumpfish were introduced onto site on 08/11/2021.
SAV detected from a sampling conducted on 01/02/2022. Low level PD ongoing for a couple months, with mortality and feeding not being affected. Positive samples were found in pen 3 and pen 9.
Last freshwater treatment conducted w/b 09/05/2022. Cleanerfish have been handling the treatments well as site has put in place measures to mitigate against cleanerfish loss. The freshater treatments are limited to 1 hour to ensure that ballan wrasse survive. In addition, new system includes a dewatering facility where ballan wrasse and lumpfish are captured and are stored in a seawater tank until treatment is complete.
Harvests are conducted as live haul and are taken to Ardyne and then onto processing at Cairndow.
