Gigante opts for nanobubbles
Landbased salmon farmer chooses Moleaer's Freya system after pilot success
Gigante Salmon has chosen Moleaer's Freya nanobubble system as its primary solution for oxygenation at its production facility on Lille Indre Rosøy, Rødøy municipality, Norway, the companies announced in a press release.
According to the companies, the decision was made after a successful pilot project during periods of high oxygen demand, where Freya delivered more stable levels of dissolved oxygen (DO) with good installation flexibility.
With Freya, Gigante Salmon can increase oxygenation capacity as biomass increases, without major infrastructure changes or increased system complexity. The company began integrating the systems in 2025 and will scale up with more systems over the next year as production increases.
"Freya solved the oxygenation challenges we had previously. It was a new world for us when we experienced the strong improvement in oxygen uptake with nanobubbles. We have to say that this was a necessity for our operation and Moleaer's technology is definitely a contributor to us reaching our production goals," said Tore Laugsand, assistant chief executive at Gigante Salmon.
"The flexibility allows us to scale in line with our production needs."
Full operation next year
Gigante Salmon will begin harvesting its current generation towards the end of the current quarter. Gigante Salmon expects to have the entire production facility fully operational during the second quarter of 2026.
Further development of the facility is in its final phase, with two of three production basins completed, on track for a planned ramp-up to full capacity of 16,000 tonnes annually from 2028.
Moleaer's nanobubble technology is developed for cages, holding tanks, hatcheries, recirculating aquaculture systems and emergency use.
"Producers usually do not have a problem with oxygen supply, but with oxygen release," said Moleaer's Inge Haarberg.
“Freya solves this by delivering oxygen where the fish need it, with market-leading gas redemption efficiency to improve water quality while reducing oxygen and energy costs. It gives producers a more robust and cost-effective way to maintain stable DO levels as biomass grows.”
