21 VMD samples collected from 5 cages. Inspection of the smolt undertaken Fry tanks and hatchery were not inspected during the visit.
Within tanks A1 and B1 one moribund fish from each tank was removed for further observation. No obvious post-mortem signs of disease were observed and therefore no diagnostic sampling was undertaken. The fish observed on site looked in good condition. [Original PDF]

Underground tank used to collect ensiled waste. Separate ensiler for smolt unit and hatchery, both "on-site".
Import planned from Iceland in December 2021.
Water temperature very high at the time of the inspection at about 18.6 degrees C. Temperature kept above 16 throughout the cycle.
Some abrasion visible on the flank of some fish, reportedly due to some fish attacking others.
The site is on a recirculation system.
Eggs are kept on site in comp-hatch units. Once the fish have hatched and are large enough to move through into the grow-on tanks they can be pumped through pipes into the larger grow-on tanks,
One fish sampled for VMD showed signs consistent with vaccination damage. The site confirmed that fish from that tank had been vaccinated. Once the fish was opened up, no other signs of disease were noted, so no diagnostic samples taken. All other fish sampled for VMD appeared clinically healthy. [Original PDF]
