A significant fall in volumes and burdensome raw material prices dragged down results for Norwegian salmon and trout processor Sotra Fish Industries in 2018.

The most significant drop was operating profit, which fell 81 percent to NOK 3.3 million (€339,900/$382,800) last year. Revenue also decreased by 11 percent to NOK 411 million (€42.3 million/$47.7 million).

With the exception of the company's modified atmosphere packed (MAP) line, there has been a decrease in production volume across all other departments, and the company says results were as expected given the economic climate.
