Download Salmon came on from Barcaldine Smolt Unit (Stofinfisker origin) and Girlsta Hatchery (Aquagens). Stofinfisker stock is reported to be performing well, however the Aquagen stock reduced feeding in recent weeks and the decision has been made to begin harvesting these cages. Reduced feeding combined with the presence of AGD/CGD on site has resulted in the entire
Loch now being placed on a harvest plan, with all Kishorn sites expected to be fallow in the coming months. Livehaul harvests are taken to South Shian
Wildacaught wrasse have come on from Orkney over several movements in July/August/September 22 and June 23. The lumpfish on site were imported from Ireland in Nov 22. Wrasse morality since input: 5,157 (12.17%). Lumpfish mortality since input: 9,413 (23.53%).
Site staff had already removed moribunds in advance of the inspector arriving on site, so none were observed in any of the cages. Some lethargic fish were observed in most of the cages on site and had higher than average lice loads (compared to the general population) with some damage to the base of the dorsal fin and top of the head noted. These fish however, were responding to movement and could not be caught using the hand net, so were not sampled. The general population of fish that were sitting deeper in the water and shoaling well, appeared in better physical condition, with lower lice loads and higher body weights.
Fish sampled for VMD appeared in good physical health externally and internally upon examination. [Original PDF]

Download In week 26 the site identified a large increase in numbers of micro jelly fish (Obelia) whilst conducting routine plankton checks which resulted in acute gill damage leading to an initial spike in mortality in week 26. The levels of mortality reduced in wk 27 following a reduction in plankton levels that week however mortality began to spike again in week 28 to present as a large population have developed very pale gills (anaemia from blood loss) following the initial insult which is causing on-going higher mortality. Plankton levels are currently low. The site are currently undergoing targeted harvests to reduce biomass.
Site inspected in a calm sea state, sun and little cloud cover which allowed for good visibility of the stock. From the physical inspection of the site, the visible population of SAL appeared lethargic and slow moving in all pens. Some weaker, moribund fish were observed resting against the net walls with strong operculum movement observed. Pens 2 and 5 appeared to be in the poorest condition in relation to fish health, 2 fish from each pen was removed for diagnostic sampling. One fish in cage 8 was observed hanging vertailly which was also removed for sampling.
Only 6 pens remained stocked at Kishorn North, the site has been moved up in order of priority on the companies harvest plan and is now planned to fallow by the 18th August.
Site thermometer was used to record the water temperature as T309 was faulty.
Site is positive for AGD, last health check conducted in week 30.
Cleanerfish mortality : Week 31 - Week 28 : Wrasse : 2.33% 330 fish. Lumpfish Week 31 - 28 : 1.7% 619 fish. [Original PDF]
