Fish have been vaccinated with Alpha Ject micro1 PD and Alpha Ject Micro 6
FW wellboat treatment in August and December 2020. Hydrolicer was on site in July 21 and the thermolicer was on site in
August 21. No medicinal treatments have been required since input.
All mortalities are transferred to Doon Bay in sealed bins where they are collected by a Cooke road lorry and transferred to
Pelagia in Bussy, Shetland where they are ensiled.
Deadhaul harvests are taken to Kirkwall procesing plant within the disease management. No discharge into the DMA.
Sites within FMA are not fallowed synchronously on a single year class basis, but there is a documented risk assessment for this which was made available during the inspection.
Fish on site appeared in good health at the time of inspection. No moribunds were observed across the site.
Fish sampled for VMD appeared healthy. [Original PDF]
