Demand for sustainable seafood is increasing around the world, and consumers say supermarkets and restaurants can play a key support role by ensuring the sustainability of the seafood they are selling, according to a major survey ranked as the world’s largest international survey of sustainable seafood consumption.  An independent report commissioned by the Marine Stewardship Council (MSC) questioned 9,000 people in 15 countries across Asia, Europe and North America, and found a third of people recognised the MSC ecolabel, now carried on 25,000 seafood products available in 100 countries.  The retail value of MSC seafood reached US$4,8 billion in 2013/14 – an increase of almost 150% since 2010.  To date, 252 fisheries are certified representing 9% of the total wild catch.
