Ecofisk AS, an aquaculture start-up based in the coastal village of Nedstrand, Norway, announced that it will begin construction next year of a land-based fish farm in the southwest region of the country.

The company said it aims to produce both post-smolt and harvest size salmon at Ecofisk’s 300,000- square metre production site in Espevik in the municipality of Rogaland. The site is a former quarry operated by Amrock.

The plan involves building a recirculating aquaculture system (RAS) plant in stages. The first phase involves constructing a system that can produce 5,000 tons of salmon, according to a post on the salmon farming publication iLaks.


The publication reported that Ecofisk applied for a license last year to produce “20,000 tons of post-smolt and 20,000 tons of food fish.” The company is also looking into producing 20 million post-smolt and eight million food fish.

Ecofisk said its facility will cover the entire production cycle from roe to food fish.

The post-smolt and food fish section of the plant will consists of eight main modules of 5,000 tons each.

“Each production cycle will be divided into nine compartments (four in fish module and five in food fish module) based on known recycling technology (RAS-1) and with temperature control, water re-use and mechanical and biological treatment of water,” Ecofisk told iLaks.
