Irish figures from the Marine institute confirm that 26% of the one year salmon were above the permitted levels of sea lice, with 57% of two season salmon exceeding the treatment level in 2012.

Mainly due to disease, loses of fish doubled in Ireland in the last year and are now running at a rate four times any of the six countries Marine Harvest operates in. The report gives the main challenge in Ireland in 2012 as Amoebic Gill Disease (AGD), which affected operations in both Scotland and Ireland, with the Irish biological assets halving in the last year.

Ireland also had the highest number of reported fish escapees in Marine Harvest world wide operations – double the number of the nearest other country – Canada.

Progress towards the goal of making fish food more sustainable by avoiding the use of fishmeal (excluding trimmings) also bucked the trend world wide with fish meal consumption in Ireland tripling in the last three years.

The Annual Report shows that Ireland was the only country that showed an increase in the use of fish meal with the amount of fish meal in the diet increasing from 3% to 11% from 2010 – 2012. Estimates of the amount of wild fish catches used for aquaculture world wide to vary by regions from 33% to 50%.
