We experienced a spike in mortalities at this site in September due to high numbers of plankton and jelly fish and a general reduction in dissolved oxygen in the water.

We have been experiencing unusual weather patterns this summer which we believe has led to these changes in water quality.

Environmental conditions on site significantly improved when the weather broke a couple of weeks ago and the site is now rapidly recovering.

No other site was affected.

All farmers face new environmental challenges. We are confident that through our commitment to environmentally low impact solutions, we can overcome these.

“Monthly mortality (%)” = the percentage of fish lost on each farm within each month. This is reported as a percentage of the total number of fish on the farm each month. This is the measure of mortality used by the Scottish Government’s Fish Health Inspectorate when assessing the health of the fish on the farm.

“Cumulative mortality over full production cycle (%)” = the percentage of fish that have died on a farm during the entire production cycle, given as a percentage of the total number of fish that were initially stocked on the farm. It can only be reported once the entire farm has been fully harvested and fallowed.

Sea lice are adult females, presented as monthly averages. Farms count sea lice every week. Figures are reported by calendar month. Therefore some months include five full weeks and some include four full weeks to cover the 52 weeks of the year.

"Fallow" = the farm was fallow or empty throughout the entire reporting month.

“Farm stocked in October.” = the farm was fallow or empty at the start of the month but was restocked during the month.

"Farm fallowed in October." = the farm was stocked at the start of the month but became fallow or empty during that month.

“No count – Harvesting” = fish were being harvested throughout the month. Under such circumstances it is not always possible to record the lice count.
