Atlanto-Scandinavian herring and blue whiting fisheries' loss of Marine Stewardship Council (MSC) certification will ratchet up pressure on the aquaculture feed and farmed salmon sector, who are already being criticized over the sustainability of raw materials, according to an executive with Cargill, the world's second-largest aquaculture feed producer.

The MSC stamps will be suspended on Dec. 30, affecting eight certificates covering fisheries from the European Union, Norway, Iceland, Russia, the Faroe Islands, Greenland, and most recently the United Kingdom, which claimed independent Coastal State status in 2020.
