Fish on site will be 2020 S0 -Put to sea in October. They will be held onsite until about 10-15g then transferred to Loch
Garasdale and Furnace,
Current stock imported as ova from Stofnfiskur.
Mortalities are ensiled on site and collected by Hasco about once a year. Transported by tanker to Energen biogas plant,
Deerdykes wk 13/1/20 Issue with spate and matting caused mortality increase due to suffocation in C section; 16,000 morts on Sat
18/1/20 and 65,591 on Friday 17/1/20. Morts now back to normal.
Last cycle some fish held until S1. Not planning to do that this year due to water shortage in the summer.
High morts in spring 2019, poor water quality resulting in morts attributed to fungus and lesion only in C section. - 27/5/19 approx. 70.000 lost at 0.25g in C section. 10/6/19 peak; about 153356 morts for C section in week. Wt 0.4g

Unreported mortality 2022/wk21 5g to smolting 2.03% (27,952); first feed to 5g - 0,72%; whole site 1.4% stock split: for 2023/wk06 whole site 2.02% (64,286) of which 55,000 failed ova.
Ensiled wasted collected by Denam environmental.
Water temperature: UnitB = 9.5C, Unit C = 9.4C, Unit E = 3.6C
Smolts: Some fin damage was evident in some tanks, some tanks this seemed to be more the pectoral find in other tanks this seemed to be more the dorsal fin. Water very clear and otherwise fish appeared to be in good condition. Fish sampled for
VMD appeared healthy.
Fry: These appeared to be in good condition. Aquagen (from Quoys) and Stofnfiskur stock on site. Aquagen stock seemed to be moving through the water column more freely, whereas Stofnfiskur stock appeared to congregate at the bottom of the
Alevins: Appear to be in good condition. The way these are hatched in small tanks, rather than comp hatch tray makes removal of dead eggs more difficult. Dead egg with fungus were observed in a few tanks. These don't appear to cause any issues and will be removed once fish are moved. Site generally very little fungus problems.
Surveillance Frequency assessment amended 16/10/23: Compliance with CoGP/Regulator changed from Yes to No, adding 3 points. Changing the surveillance frequency from Medium to High. EC report reissued with amended surveillance frequency. [Original PDF]
