Andfjord Salmon reports 99.58% fish survival after six months in tank
Growth has also exceeded expectations at Norway flow-through facility
Land-based fish farmer Andfjord Salmon has reported that growth in its first two stocked pools at Kvalnes, on the Norwegian island of Andøya, is increasingly outperforming expectations.
The aggregate survival rate stood at 99.59% at the beginning of this week, after six and four and a half months in pools K0 and K1, respectively.
Andfjord said the high survival rates, coupled with growth ahead of schedule, means that the facility's standing biomass is growing rapidly. At the beginning of this week, total standing biomass was 902 tonnes live salmon, up approximately 70% since the beginning of the year.
Accumulated feed conversion ratio currently stands at 0.97 for pool K0 and 0.88 for pool K1, demonstrating efficient feed utilisation. The fish are being fed Andfjord Salmon's specially designed feed - Calanus Plus by Andfjord Salmon - that among other things contains the zooplankton Calanus finmarchicus and algal oil.
Stimulated appetite
“Growth in both K0 and K1 has exceeded our expectations, including when taking into account higher than expected water temperatures, which have further stimulated appetite and accelerated biomass development,” said chief executive Martin Rasmussen in a press release accompanying the company’s report for the fourth quarter of 2025.
“A core objective of implementing our flow-through system at Andøya has been to replicate the salmon's natural habitat on land, while at the same time reducing exposure to several of the challenges associated with traditional sea-based farming. The results achieved to date demonstrate that our core objective is attainable.
“That said, we remain committed to continuous and rigorous monitoring of pool conditions, fish health and overall welfare to ensure that the strong start we have experienced is maintained over time.”
Construction continues
Andfjord is continuing to build new flow-through pools at the Kvalnes site following a dispute with its former main contractor last year. Andfjord said the new main contractor, Entreprenør Harald Nilsen AS, and its subcontractor, Nornebygg AS, have completed their move on to the site and are currently progressing as planned with pools K3, K2 and K4.
Andfjord Salmon raised NOK 300 million in new equity from larger existing shareholders in Q4, together with enhanced bank debt of NOK 200m. The farmer, which is currently in the middle of a production cycle and therefore receiving minimum sales income, reported a net loss of NOK 73.9m for the quarter.
