Download Cleaner fish mortality - WRA - 24.1 % LUM - 53% since input Lumpfish mortalities were suspected to have been caused by
Tenacibaculum maritimum and florocol has been administered.
Hydrolicer treatment in week 47 led to an increase in mortalities, although mortalities remained below the reporting threshold.
Peroxide treatment for gill health, limited excess mortalities.
PRV-1, the causative agent of HSMI was confirmed onsite during routine health screening, although there has been no associated clinical signs.
Sea lice numbers remained below intervention level until week 49 when they rose to 1.1. Site has been conducting mechanical treatments since WK 47 when numbers began to rise.

Are working on agreeing a Farm Management Agreement but this is not yet in place. Farm management statement inspected.
WRS left over from last cycle, with risk assessment. New input of lumpfish for current stock. Risk assessment for SAL movement from Port na Cro to Kingairloch inspected. Movement required due to biomass.
Some smaller slower moving fish observed in some cages, a few fish with lesions/damage observed deeper in the water column in a few pens, however these were swimming actively and were out of reach. Two lethargic fish were removed and dispatched. One had a damaged eye but was otherwise a large health fish, the other one appeared to be a poor dooer with darker coloration. The fish was opened up but no gross pathology was observed so no samples were collected. From the last pen 6 dead lumpfish and a few SAL mortalities were removed. This pen had been attempted to do a swim through the previous day but the net had gotten tangles with a rope, which is thought to have been the cause of the mortality. Fish sampled for VMD appeared healthy. [Original PDF]
