Sigerfjord Fisk AS has worked with farming Arctic char for a long time and is currently the largest producer in the world. The turning point was when they started using SOLVOX® DropIn oxygenation solution from AGA. From a previous 7-10 tonnes of fish per net pen, this increased to 25 tonnes per net pen today.
MD of Sigerfjord Fisk AS, Trond Geir Reinsnes, is very clear about the significance of how important this solution has been for his business:
“We probably wouldn’t be in production today if it weren’t for SOLVOX® DropIn from AGA.”
One of the reasons for this statement is that Sigerfjord uses open net pens with tarpaulins with open bottoms in seawater. This has led to challenges with adding oxygen to the net pens.
“In the summer months, when the temperatures were favourable for growth, we had a problem adding adequate oxygen via freshwater, which caused unfavourable production in the form of low growth, high mortality and high feed conversion factor.”
Visited AGA’s research centre
This resulted in Reinsnes inviting himself to AGA’s Innovation Center for Aquaculture and Water Treatment in Ålesund in 2014.
“We had experimented with several of our own solutions for oxygenation in our net pens without satisfactory results.”
From this visit, Sigerfjord Fisk got a prototype that they tested in a net pen. It didn’t take long before they ordered 6 SOLVOX DropIn units.
“The new DropIn solution puts us in a position to control the oxygen level in the net pen. Today, we have a total of 10 net pens that all get oxygenation from the SOLVOX DropIn solution,” he says.
Account Manager Jan Arvid Todal from AGA is very happy with the positive cooperation and praises Sigerfjord Fisk for their efforts and willingness to put new technology to use.
“For us, the cooperation has developed into friendship and we share experiences and always work to offer the best solutions,” says Todal.
The Head of AGA’s Innovation Center in Ålesund, Tore-Jakob Reite, agrees:
“Sigerfjord is an exciting player in the aquaculture industry and an important customer for us. Their Arctic char have even been served at the Nobel Banquet,” he says.
Trond Geir Reinsnes says they will slowly speed up over time in the future:
“Our goal is to develop ourselves gradually and take it step by step. We don’t want to grow too fast and right now we feel like things are going like they should,” he concludes.Sigerfjord Fisk AS
