The survival of Atlantic salmon in all of Cermaq’s farming regions has improved over the past year, leaving its global annual mortality rate now spanning four to six percent, the company has reported.
The Oslo, Norway-headquartered, fully-owned subsidiary of Mitsubishi Corporation publishes quarterly sustainability results on key indicators related to fish health, environmental, and social topics.
For the quarter July through September 2017, Cermaq Norway’s salmon survival rate increased to 96 percent, compared with 94 percent in the corresponding period of 2016. Similarly, survival in Canada improved from 91 percent to 94 percent and Chile’s improved from 92 percent to 94 percent.
At the same time, the use of antibiotics in Chile and Canada was significantly reduced for fish harvested in the quarter compared to the same period of last year. Cermaq Norway normally does not use antibiotics, but did use them in one pen in fall 2015 that was harvested in this quarter.
Meanwhile, Cermaq Chile experienced one escape incident where 207,000 fish were lost in a major storm. There were no escapes in Canada or Norway.
