The salmon farming industry is still a long way from addressing the urgent issue of feed-source sustainability, according to research from investor network FAIRR, which claims the industry is heading for a supply shock that could seriously derail growth plans.

The claim comes as FAIRR, whose investor membership collectively has $48 trillion (€42 trillion) in assets under management, launches an engagement program targeting eight global salmon companies, asking them to develop and disclose strategies for diversifying feed ingredients towards lower impact and more sustainable alternatives.
