Andfjord Salmon will begin harvesting this month
The Norwegian land-based fish farmer says in a stock exchange release that its fish experienced strong growth and high survival in September, with particularly strong growth in pool K1.
As of September 30, 2026, the biological key figures for the company's three operational pools – K0 (food fish), K1 (food fish) and K3 (post smolt) – were as follows:
Total standing biomass: 2,580 tonnes, up 25% in September
Net production in September: 512 tonnes
Overall survival in 2026: 97.98%
Accumulated feed conversion ratio in 2026: 1.036
Average weight per fish: 3,502 grams (K0), 3,485 grams (K1) and 720 grams (K3)
Hockey stick effect
Andfjord, which grows fish in flow-through pools at Kvalnes, on the island of Andøya, says that growth in pool K1 was particularly strong in September and the previous months, after the biomass was reduced in June when around 450,000 fish were sold as post-smolts.
The average weight per salmon in K1 was 3,485 grams on September 30, up 31% since the beginning of September and 263% since the end of June.
“Growth in pool K1 has been solid from day one, but we have seen [an ice] 'hockey stick' effect after we reduced the biomass density in the pool in June. This is in line with our strategy of utilising available pool capacity to maximise production volumes, then reducing the biomass and stimulating a steeper growth curve for the fish remaining in the pool,” said Andfjord chief executive Martin Rasmussen.
Preparing for harvest from K0
Andfjord Salmon says it is now preparing to harvest the first group of food fish from pool K0. Here, the company will use the same strategy of gradually reducing biomass density to stimulate a steeper growth curve for the remaining fish.
The fish in K0 will therefore likely be harvested in three different rounds between October and the first quarter of 2027, at different weight intervals.
Andfjord Salmon estimates that the harvest weight in live weight from K0 and K1 will vary from 3.6 kilos at the first harvest to around 5.6 kilos at the last.
The average harvest weight is thus estimated at over 4 kilos (head on gutted), which according to the company is in line with its long-term strategy of an average harvest weight of 4.0–4.5 kilograms.
"By harvesting some of the salmon earlier than the rest, the remaining fish can reach higher harvest weights more quickly. This is a production plan that makes sense both biologically and economically. We look forward to entering an exciting harvesting period," said Rasmussen.
