Gigante Salmon Selects Moleaer’s Freya Nanobubble System to Improve Oxygenation at Lille Indre Rosøy
Advanced oxygenation technology stabilizes dissolved oxygen levels and supports production targets
Hawthorne, Calif., December 17, 2025 – Gigante Salmon has selected Moleaer's Freya nanobubble system as its primary oxygenation solution at its production facility at Lille Indre Rosøy. The decision follows a successful pilot conducted during periods of high oxygen demand, where Freya delivered more stable dissolved oxygen (DO) levels while offering installation flexibility.
With Freya, Gigante Salmon can increase oxygenation capacity in step with growing biomass, without major infrastructure changes or additional system complexity. The company began integrating systems in 2025 and will scale up with 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,” says Tore Laugsand, Deputy CEO of Gigante Salmon. “The flexibility allows us to scale in line with our production needs.”
Gigante Salmon will begin harvesting a new generation toward the end of the fourth quarter of 2025. The company expects the entire production facility to be fully operational by the second quarter of 2026. Further expansion of the facility is in its final phase, with two of three production basins completed and on track for a planned ramp-up to full capacity of 16,000 tons annually by 2028.
Moleaer’s nanobubble technology is designed for sea cages, holding tanks, hatcheries, recirculating aquaculture systems, and emergency use. Nanobubbles remain neutrally buoyant and support key biological and physical processes in water, helping producers improve oxygen efficiency, enhance fish performance, and manage oxygen costs more effectively.
“Producers don’t typically have an oxygen supply problem but with oxygen dissolution,” said Inge Haarberg of Moleaer. “Freya addresses this by delivering oxygen where fish need it, with market-leading gas transfer efficiency to improve water quality while reducing oxygen and energy costs. This gives producers a more robust and cost-effective way to maintain stable DO levels as biomass increases.”
With hundreds of installations globally, Moleaer’s nanobubble solutions help aquaculture producers improve oxygen efficiency, strengthen fish welfare, and reduce energy and oxygen consumption.
