Case Number: 2020-0032

Download Mortality report received from business on 24/04/2020. w/b 13/04/2020 - 19310 (1.17%) attributed to post treatment losses (freshwater).
FHI contacted business for further information and to conduct a PSI.
The business had also previously reported increased mortality w/b 06/04/2020 - 29874 (1.77%) - attributed to post treatment losses (freshwater).
Additional weeks mortality checked: w/b 30/03/2020 - 1800 (0.1%). w/b 20/04/2020 - 3901 (0.2%)
No other peaks in mortality during this production cycle.
The freshwater treatment was for AGD, carried out using a wellboat. Treatment beginning 06/04/2020 and finishing the following week, all 20 cages treated at 2 cages per day. Poor weather during a couple of days caused crowding to take longer, with fish being left in crowd for longer than usual, thought to have exacerbated losses. Pens 9 and 10 worst affected. Mortality has fallen significantly during most recent week (w/b 20/04/20). No further treatments are currently planned.
No other underlying health issues, sea lice numbers low.

Download Storm Ellen struck. In a yellow warning area for high winds from Wednesday into Thursday. Wind: southerly
NO attempt was made to capture fish. The issue of recapture was discussed with local fishery boards.
There has been an increase in the number of local fishermen visiting the area. The site staff are unaware if any salmon have been caught.
Last Thursday 10:00-10:30 call from site letting senior management know that the whole group of cages in the northern half of the site were moving north. Thursday the group was secured by a well boat and tug boat. 6 pens were intact, 4 were damaged
(in the northern half of the site). Divers were in on Friday together with an ROV. Holes in pen 1 (which was written off) and 4 were detected. Four pens were harvested and morted (figures below)
Pen 1: 48,124 (total), 29,125 (dead) 18,999 (missing),
Pen 2 and 3 all harvested (morts - cage 2: 150, cage 3: 1,125)
Pen 4: 46,195 (total), 216 (morts), 16,144 (harvested), 29,835 (missing)
All harvesting on Friday and Saturday. All processed by Tuesday.
Site staff were on site on Thursday, they returned to shore early in the morning when conditions deteriorated. They could see from the cameras on site the pens were moving. The team drove north up on a hill overlooking the site and could see the pens were moving north. The cages swung around 180 degrees north west (clockwise) due to the wind coming from the south east.
The Ronja Fisk well boat and a tug were nearby and attached a bridle rope to a cage to secure the pens. All ten cages were attached to each other.
DC arrived at about 16:00. A tug was operating nearby in Loch Fyne and was called to secure the cages between 16:00-19:00.
Tug called Kingdom of Fife. Most southerly pens and grid buoy attached to tug. Ronja Fisk were also attached to most southerly cages to hold them in place over night. Team on site by about 6am on Friday. Started working to assess damaged pens at 10am. The cages were secured to the grid already. The fish were removed from the pens next. Divers arrived at 8am with an ROV at 10-11am. Took about two hours to check the pens with ROV and divers. The hole in cage 1 was repaired using a sweep net. The sweep net had a lead weight holding the bottom tought and the top was secured to the water line of the netting. Cage 4 was repaired by divers using thread to secure the holes. Fish from cage 2 were harvested first. Had to start on cage 2 as it was on the outside of the grid and the easiest to access. Once this pen was moved out of the way the other pens could be tended to. Then pen 4 and pen 3 harvested. Morts from pen 1 being removed whilst harvesting and removing fish from other cages. Morts removed using "Foover" and uplifts. The "Foover" uses jets of water to move fish into basket and then uses a ROV to bring basket to surface. Morts placed on a mort bin on work boat and either ensiled on the barge, or transferred into skips on Ferguson work boat. Once skips at shore they would have been transported to either Dundas or
Energen Biogas in Cumbernauld. Billy Bowie supplied skips and Ferguson Transport the lorries and boats to shift the waste.
What caused holes is unknown on pen 1. Pens 4 had a buoy wash into it causing a hole. The deformation of pen 1 probably meant that the net had undue stress in places that it wasn't supposed to causing a hole to rip. However this is unconfirmed.
Broken mooring ropes has been sent to Aberdeen for assessment. Multiple mooring lines snapped. Once one went that put more stress on other ropes causing a chain reaction, this is also unconfirmed. Unknown at present how many ropes snapped.
Harvesting of stock was undertaken by Ronja Fisk, Ronja Harvester and Ronja Challenger. Grip fisk and Ronja Viking on stand-by. All fish from affected pens went to Mallaig for processing. All fish to Ireland were planned to be harvested anyway.
Fish not counted on site as the pens have been ROV and diver checked and no holes were found. There are no plans to count these cages as it is thought very unlikely fish escaped without any holes detected.
No attempt made to recover fish due to safety concerns associated with bad weather. has been in touch with fisheries boards. Local people have been seen trying to catch fish using a rod and line but it is unknown if anything has been caught.
Cages moved approx. 200-300m.
WRS from the wild, LUM hatched at Anglesey (Mowi owned).
LUM and WRS were harvested out of the affected pens and were culled at Mallaig.
Mortality before the incident was slightly elevated caused by gill challenges and harvesting.
LUM came onto site at 27g-35g and some are around 120g at the time of the remote inspection. LUM are now between 27g -
120g as they have come onto site at different times
Last lice count was done on 16/08/2020 due to the site staff being busy with harvesting and dealing with latest incident.
Four damaged cages to move off the site the day of the physical inspection. These will go to Kishorn for repair. Since the aerial footage the cages have 'sprung back' into a circular or near circular shape. Nets sent to Knox base in Kilbernie for washing and repair. If the nets are not repairable they will be disposed of by Knox.
Foover removed fish into tubs on a work boat. Morts disposed off in three ways. Ensiler capacity on barge is 64,000L and that was filled up. Second route for disposal was Billy Bowie skips sitting on a Ferguson transport boat. The skips on the work boat were unloaded into Billy Bowie skips on Ferguson transport boat (each skips holds about 12 morts tubs full) and these were then taken to Tarbert where they were unloaded onto a truck and taken to either Dundas or Energen biogas in Cumbernauld disposal points. Third method was the mort tubs on a Mowi work boat were taken to the harbour where a Billy Bowie tanker will meet them to suck whole fish out of the tubs and taken to Energen or Dundas.
