Norwegian Atlantic salmon producer Leroy Seafood has been investing heavily into the fight against salmon lice -- and it's learning from the past year.

"The experience of the past year means that we are now investing significantly more in the fight against lice," said Sjur Malm, CFO at the group, during the quarterly result presentation last week.

As a consequence, the company also plans to harvest less in the second quarter of the year.

"As we reported, biomass at the beginning of 2017 was at the same level as in 2016," Malm told IntraFish.
