Feed consumption higher than salmon intake.

The Norwegian salmon biomass is estimated by data provider Akvafakta to be 819,000 tonnes at the end of September. This is three per cent more than at the same time in 2020. While the harvest volume was high, at 156,000 tonnes, feed was even higher, at 236,000 tonnes.

The growth conditions are at their best in late summer / early autumn, which is the high season for salmon feeding. The average temperature in the sea at the measured fish farms was 12 degrees.

Most of the biomass is the so-called zero-year-old of the 2020 generation. This has an average weight of 3.2 kilos, which is 100 grams more than the 2019 generation had at the same time last year.

While the salmon biomass in Norwegian fjords was three per cent heavier than 12 months earlier, the trout biomass, with its 40,000 tonnes, was two per cent lower. Both feed sales and the trout harvest fell by eight per cent.
