Gigante Salmon has selected Moleaer’s Freya nanobubble system as its primary oxygenation solution at its production facility at Lille Indre Rosøy, following a pilot carried out during periods of high oxygen demand, the companies said on December 17.
The companies said Freya delivered more stable dissolved oxygen (DO) levels during the pilot, while also offering installation flexibility. Gigante Salmon said the system allows oxygenation capacity to be increased as biomass grows, without major infrastructure changes or added system complexity. The company began integrating systems in 2025 and plans to add additional units over the coming year in line with production growth.
“Freya solved the oxygenation challenges we previously faced. It was a whole new world for us when we experienced the significant improvement in oxygen dissolution using nanobubbles. We have to say this was a necessity for our operating model, and Moleaer’s technology is definitely a contributor to achieving our production targets,” said Tore Laugsand, deputy CEO of Gigante Salmon. “The flexibility allows us to scale in line with our production needs.”
Gigante Salmon said it expects to begin harvesting a new generation toward the end of the fourth quarter of 2025, and that the full production facility is expected to be fully operational by the second quarter of 2026. The companies said further expansion is in its final phase, with two of three production basins completed, and the site on track to ramp up to 16,000 tonnes of annual capacity by 2028.
Moleaer said its nanobubble technology is designed for use in sea cages, holding tanks, hatcheries, recirculating aquaculture systems, and emergency applications. “Producers don’t typically have an oxygen supply problem but with oxygen dissolution,” said Inge Haarberg of Moleaer, who said Freya is intended to improve gas transfer efficiency and reduce oxygen and energy costs.
Moleaer said it has hundreds of aquaculture installations globally and more than 4,000 installations across all industries in over 55 countries.
