Fish have been taken from Hellisay to reduce biomass rather than fallow. Only 2k of Rum fish left - being harvested out tomorrow.
Plan to have 7 pens of Fish from Hellisay stocked at site.
CGD was on-going on site, background AGD, gill checks were seeing anaemic fish, fish bleeding out during lice counts.
Heavy stocked pens were seeing high mortality - Dips in oxygen at night time and late afternoon.
High biomass pens took largest hit at first. Large amounts of jellyfish observed in water at time of mortality event. Mortality attributed to poor gill health and enviromental insult. P. pileus and Aglantha sp identified from water sampling.
Uplifts moved onto site to remove excess mortality - extra boats and bins brought in to deal with mortality.
After test treatment was conducted, it was decided to remove all fish from site, crowds sustaining high mortality.
Round of AMX treatments completed in August prior to event. Very good clearance for caligus, low numbers of leps.
Lice numbers have increased since beginning of mortality event, as treatments could not be conducted due to poor gill health of the fish.

Remote inspection done on 08/03/2022 by , observed by .
Recent high mortalities due to CMS. Harvesting targeted for worst affected pens. All events reported to FHI.
Stock from Hellisay. Mowi made the decision to transfer the fish to Rum in order to fallow Hellisay to avoid stocking the site during winter/poor weather conditions. Risk assessment completed prior to transfer.
Lumpfish farmed at Otterferry, input in October.
Some issues with Caligus in summer due to high numbers of wild fish, regular Alphamax treatments to keep it under control.
Site avoids stocking smolts during this period.
The farm is not currently part of a CoGP management area, however they had prepared a satisfactory farm management statement and this was available for inspection.

Inspection of records and documents carried out remotely on 12/05/2023.
Site is currently not in a FMA but do have an adequately prepared FMS which was available for inspection.
Site has seen a slight increase in seal activity but no damage to nets but will be changing to Seal Pro nets prior to next cycle.
Only 2 lethargic fish observed from all stocked pens. But no clinical signs of disease. The occasional runt also observed but less than 1 per pen. Fish remained low in the water so hard to see but when spotted were observed shoaling as in normal behaviour. Fish that were removed for vmd sampling looked in good condition. No clinical signs of disease upon internal examination.
Site mainly grows fish to harvest size with a mixture of live and dead haul going to Mallaig. There is the occasional movement off site to other sites but just tends to be a single site per cycle when it occurs. [Original PDF]
