Strong demand and low supply in North America boosted Grieg Seafood earnings at its Canadian operations in the second quarter, but high use of antibiotics at its British Columbia farms and delays in Newfoundland related to disease were areas of concern.

Grieg's Canadian operations, which as of now include farming only in British Columbia, saw earnings in the second quarter before interest, tax, depreciation and amortization (EBITDA) rise to NOK 68.5 million ($7.7 million/€6.6 million) -- nearly five times what the company earned through the second quarter of 2020.
