Fish came on from Inverkerry Hatchery (FS1061) in April 21. Lice numbers increased in May (but remained below the reporting threshold) so the site received a SLICE treatment in wk20. Lice numbers remained above 0.5 so a Salmosan treatment was conducted w/b 24/05. Lice numbers dropped significantly.
SLICE treatment planned for July following 30day weight.
Lumpfish on site came on from Ocean Matters in May 2021 and were stocked at 6%. Lumpfish mortality since input has been
5.13% (2,612).
Fish observed on site appeared healthy with little to no physical damage observed on the stock. 1 salmon mortality and 6 lumpfish mortalities were observed across the site. Not fresh dead so no samples taken.
Fish sampled for VMD appeared healthy and demonstrated a good feed response. [Original PDF]

Site is currently freshwater treatment for AGD, although mortality still remains below the reporting threshold.
Most mortality on site is caused by seal predation. Currently moving across to Seal Pro nets 4 have been installed so far, with more coming. On these cages, seal mortality is considerably lower. [Original PDF]
