Land-based fish farmer Salmon Evolution registered a record high biomass production in March with approximately 320 tonnes in net biomass gain for the month, the Norwegian company said in a market update today.

As of 31 March 2023, the company’s standing biomass was almost 1,500 tonnes live weight, double the 733 tonnes biomass on 31 December 2022.

The fish are the company’s second batch, with the first batch successfully harvested in the final quarter of last year.

As of 31 March 2023, batch 2 consisted of four subgroups with an average weight of ~3.5 kg and with the largest group ~3.7 kg.

Harvest starting in May

The company expects harvesting of batch 2 to start at the beginning of May, and the entire batch to be harvested by June.

“Mortality has remained low with batch 2 with an accumulated mortality of 2.2% with ~1 month left until the start of slaughter,” Salmon Evolution wrote.

At the end of February, the company introduced batch 5 to its hybrid recirculation / flowthrough facility at Indre Harøy, an island very close to the Norwegian coast. The stocking comprised approximately 257,000 fish with an average weight of 230 grams.

Batches 6 and 7 are planned to be introduced into the facility during the second quarter of 2023.
