Case Number: 2021-0094

Download Reported sea lice number Wk 14 0.46 adult female Leps, site records for Wk 14 were 0.41 adult female Leps. Discrepancy due to second count conducted on site.
Some physical damage observed, site staff were actively removing these from the pens. Some runts and lethargic fish observed however these could not be caught for further examination. The general population appeared in good health.
Virtual inspection led by supervised by . Mortality and medicine records inspected up to the 30/4/2021 during virtual inspection. Site inspection and sampling carried out on 5/5/2021 by and

Download Fish came on from Barcaldine in June/July last year and were performing well until recent months when feeding reduced.
Wrasse are wildcaught and lumpfish came on from Ireland in December 22.
Wrasse mortality since input: 7,915 (23.87%). Lumpfish mortality since input: 11,297 (22.59%).
AGD/CGD on site has been attributed to elevated mortality in recent weeks. Entire Loch is now on a harvest plan, removing the worst affected cages first. Live haul harvest are taken to South Shian.
Freshwater treatments have been conducted since the beginning of the year but business wants to reduce handling before harvest.
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 Site inspected in a calm sea state, sun with little cloud cover which allowed for good clear visibility of the stocks.
From the physical inspection of the site, a large population in each pen was observed shoaling and moving actively. There were approximately a dozen to two dozen lethargic / moribund fish observed in each pen. 5 fish displaying clinical signs of disease were removed for diagnostic sampling. The gills of all 5 fish were very pale and anaemic, indicative of a recent environmental insult, internally the fish appeared healthy, with no clear signs of disease observed.
The site is currently using both wrasse and lumpfish, both species were observed during the inspection with both stocks appearing healthy. No clinical signs of disease were observed across the site in either of the two cleaner fish stocks. Lumpfish are from Bantry (Ireland) and Wrasse are wild caught from Scotland.
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. In recent weeks the site have been conducing targeted harvest to reduce biomass, the site is now planning to fallow by the end of this month as mortality is still elevated and on-going.
Site thermometer used to record water temperature as T309 was faulty.
18/07/2023 - 3/6 fish sampled tested positive for pasturella, 6/6 positive for AGD.
Cleanerfish mortality : Wrasse - Week 28 to Week 31 was 0.41% (60 fish).
Cleanerfish mortality : Lumpfish - Week 28 to Week 31 was 0.54% (139 fish) [Original PDF]
