Site manager expects they will be preparing less medicate feed on site due to the change of roll from larval rearing unit to broodstock site. [Original PDF]

positive for atypical furrunc from one broodstock fish - fish showed no clinical signs and appeared to be living with pathogen asymptomatically .
January 2020 - furrunc infection - slightly increased mortality - treated with antibiotic feeds
Broodfish are tested for atypical furrunc before every spawning period as standard.
Water was above 14 degrees Celsius so ECI could not be completed. REG conducted instead.
Fish looked healthy and in great condition. Whole of Larval rearing unit is now used to hold spawning fish with one building used for spawning. Eggs are now collected and Larval fish send down to Anglesey for ongrowing. No fish are currently reared at larval rearing unit for transport to site. All movements off go to Anglesey.
Site does not get sea lice on site as water is completely filtered coming into the site, so no sea lice records are kept. Wrasse are not parasitized by Leps. All fish on site are inspected daily and if sea lice were to be present they would be recorded. This has never occurred in the history of the site however.
