A global push is on to certify aquaculture operations. The group that appears to be leading the drive is the World Wildlife Fund (WWF). By June 2011, an independent body co-founded by the WWF – the Aquaculture Stewardship Council – will be fully set up to do certifications, the organization reports. It’s thought that by 2040-50, the aquaculture industry will have to increase production 50 per cent from current levels to meet demand.
