Oslo-listed Norway Royal Salmon (NRS) harvested 7,100 metric tons in the fourth quarter, down 22 percent year-on-year.

The full Q4 report will be released on Feb. 16.

Fully integrated aquaculture group NTS recently upped its stake in NRS from 16.2 percent to 29 percent while disposing its shares in Icelandic salmon farmer Ice Fish Farm.

NTS aims to take part in producing 100,000 metric tons of salmon in Norway in the next three to five years, Chairman Nils Martin Williksen said.
