Moleaer launches submersible nanobubble system for salmon farming
Moleaer has launched Freya, a fully submersible nanobubble system for oxygen delivery, following field trials in Norway and Chile.
The system cut oxygen use by up to 41 percent and reduced oxygenation-related energy use by 60 percent in trials, while delivering more than 50 kg/hr of oxygen at over 85 percent transfer efficiency, according to a press release fromt he company. Moleaer said Freya stabilises dissolved oxygen during harvest and high temperatures, improving fish welfare and reducing mortalities.
SalMar Innovanor used Freya to double dissolved oxygen levels during harvest operations, while Salmon Evolution has selected the system for emergency oxygenation across twelve tanks at its Indre Harøya facility.
“The industry has been looking for a solution that improves oxygen delivery while lowering energy and operating costs, and protecting fish welfare. Freya delivers on all counts,” said Warren Russell, chief commercial officer at Moleaer.
The company will showcase the system at Aqua Nor this week.
