5 dead observed across site, not fresh dead. Mortalities are removed using an ROV, which was reported to be very effective at the task. Nets are washed every two weeks, by net wash boat.
2 fish sampled for VMD appeared in very good condition and no sea lice observed, very few treatments reported to have been required this cycle, last treatment in May was FW followed by Salmosan, this was reported to have given a very good clearance.
Site has quite a strong tide, fish will be transferred from Ness of Copister at the end of the year for ongrowing. No issues reported on site.
Good visibility at time of inspection and fish observed shoaling well and appeared in very good condition and of uniform size.
