Download Fish came on from Shapinsay (FS0860) in Dec 2023 and have been performing well since transfer. SW to SW RA was available for the movement. A multi yearclass, non-synchronous fallow RA was also available for inspection.
Wildcaught wrasse that were stocked at Shapinsay were transferred in the movement to site. <550 were stocked on site at the time of inspection. WRA mortality for the last 4 weeks: Wk18: 49 (8.55%) (attributed to a handling event), Wk17: 34 (5.6%),
Wk16: 25 (2.83%), Wk15: 12 (1.34%)
Pharmaq health report from March 24 details very mild AGD on site but not causing elevated mortality. Histology and PCR samples were also taken by company biologist during a recent Biomar visit and were screened for CMS, SRS, HSMI, PD,
Furunculosis and Rickettsia. All results were negative.
Thermolicer was on site in April 24 and the site has reported >95% clearance and low mortality following the treatment and handling. SLICE was administered in January 22, but since then, no other medicinal treatments have been administered, with the exception of anaesthetic for sea lice counts. A FW and FLS treatment is scheduled for the week following the inspection in response to resettlement.
Site live haul harvests to either South Shian or Lerwick.
The general population of fish on site appeared in good physical health at the time of inspection, with good body condition and strong feed responses. There were ~2-3 fish per cage that appeared lethargic with some physical damage noted to the flanks and heads. The lesions were attributed to the recent handling event and appeared to be healing well. One moribund was observed across the site but no other clinical signs were observed, so the fish was not removed for diagnostic sampling.
The fish sampled for VMD appeared clinically healthy externally and internally upon examination.
