Case Number: 2020-0514


Download Site records checked up until 20/11/2020 b on 20/11/2020
Site inspection and VMD sampling by on 25/11/20, movement records collected 24/11/20.
Visibility excellent on site at time of inspection, 1 dead fish observed on bottom of net. Site currently harvest and likely to be fallow before Christmas, fish showed good feeding response and appeared healthy. Fish sampled for VMD were in very good condition, only chemical treatment required this cycle of fish (transferred in Feb 2020, from nursery site) has been hydrogen peroxide for slight AGD, this hasn't caused issues so far this year. No issues reported or observed on site at time of inspection. [Original PDF]

Download Mortalities are transferred to Dounby by Cooke in their own transport. These are then ensiled at Dounby and sent to Pelagia.
Movement records - FS numbers not recorded in movement book.
Mortalites on site have mainly been attributed to predation and AGD. Mortalities over the threshold were recorded until WK 39, however mortality has since reduced. Most recent company health report shows positive results for AGD on site. One seal was seen in the vicinity of the site.
Prophylactic SLICE treatments in April and June. Lice numbers have remained low throughout the cycle.
Mortality events - Some mortality events not reported (WK 32, 33, 34), mort spreadsheet (WK30) - 2542 - site record 10,678.
Reported retrospectively.
Overall there were very few fish showing clinical signs of disease (~2). Some dead fish were observed with physical damage from suspected seal predation.
3 fish were observed with suspected seal damage, 2 lethargic fish were observed, but these were the only clinical signs observed.
Site diary shows good performance overall, some AGD issues, as well as seal predation.
