Cermaq measures fish survival as a rolling 12-month rate. In the quarter July/August/September 2017, the improvement in Norway has been from 94 per cent to 96 per cent survival, in Canada from 91 per cent to 94 per cent survival and in Chile from 92 per cent to 94 per cent survival compared with the same quarter last year.

The Norway-based company, owned by Japan's Mitsubishi Corporation, said use of antibiotics in Chile and Canada has been significantly reduced for the fish harvested in the quarter compared to the same quarter last year. Cermaq Norway normally has no use of antibiotics, but used some in the autumn of 2015 on one pen which was harvested this quarter.

Chile experienced one escape incident where 207,000 fish escaped in a major storm. There were no escapes in Canada or Norway.

Cermaq has published quarterly sustainability results on key indicators related to fish health, environmental and social topics in our operations since the beginning of 2016.
