Remote inspection conducted by 13/07/21, site inspection and VMD sampling by 22/07/21
9/10 cages have 10m sea lice blinds installed and 10th cage has a 13m sea lice blind installed. No issues reported on site with gill swabs testing negative for AGD and histology results not indicating anything of note.
Site did experience a plankton bloom WK 27 2021, plankton included Pseudo nitzschia, feed was withheld and no issues reported.
May stock with Lumpfish later in year, dependant on sea lice numbers. Site was stocked with both wrasse and lumpfish during the previous cycle.
Fish were deeper in the water column, visibility was very good and the fish observed appeared in good condition and of uniform size. 6 failed smolts observed with some tail damage, these were also deeper in the water.
Sea lice - very low levels of caligus and no Leps counted in last sea lice count.
8 fish removed for VMD, all appeared healthy and in good condition.
One site within one tidal excursion, long term fallow with no plans to restock, but to remain active. [Original PDF]
