Earnings at Norwegian salmon and trout farmer Firda Seafood Group were given a big boost last year, thanks for improved trout prices.

Byrknesoy-based Firda landed a NOK 230 million ($23.8 million/€23.4 million) net profit, according to the company's recently released annual report.

The company reported an 8.7 percent rise in revenue to NOK 1.6 billion ($160 million/€160 million).

The company's earnings were impacted by large, one-time development costs for the company.
