Inspection reports

Case Number: 2020-0506


Download Atypical furunculosis in wrasse treated with florcenicol in June 2020. Piscirickettsia positive by PCR but no associated mots or treatments.
Tube cages on site; one circle 120m and an inner 60m circle. Outer circle is 40m deep. inner one 14 m. Lice skirt on sides of inner circle to 14m then out to outer circle. Fish can only come to surface in inner circle and are fed at 13 metres deep. Fish are caught for lice counts with a passive box net left in inner circle for fish to jump into. This works as relatively small surface for net volume. Suba divers only work 30m so have to use surface support divers. Looking into using mixed gasses. Seals still predate the cages despite no fish available in the top 14m. To allow inspection of the fish you have to climb over the outer hand rail and along a walk way to the inner circle.

Download Stock originally from Glenfinnan but moved onto site from Poll Na Gille the week before inspection.
Fish were sitting deep in the water. No moribunds were observed on the site.
Few lumpfish were seen, but those that were observed appeared to be in good condition. No lumpfish mortality has been observed on the site since input the week prior.
Fish sampled for VMD appeared healthy.
Paperwork inspected remotely 21/05/2021. Site visit completed 25/05/2021. [Original PDF]

FMA not fallowed synchronously with other operator in the FMA but that operator is farming RTR and there is high amount co- operation and communication between both operators in area.
Fish remained low in the water so hard to see. Side netting goes down 26m into the water and then a further 16m to bottom of the cone. Only a small number (avg 3/pen) lethargic fish visible. Once back at shorebase the fish were observed shoaling as expected via the cameras in the pens. Thermolicer had been on site week prior to inspection. Fish removed for vmd sampling were in good condition with no signs of disease upon external and internal examination. [Original PDF]
