No recent issues reported on site, no dead or moribund observed during the inspection. Two fish removed for VMD sampling appeared in very good condition with very few sea lice observed and no adult females.
Only 5 cages stocked as fewer fish delivered than expected, however, it was also reported that the fish delivered were a very uniformed size and are growing well.
Feeding controlled centrally from Lerwick.
Very good visibility and very calm weather.
SLICE treatment planned to begin next week. Only SLICE used this cycle. [Original PDF]
