Conventional aquaculture production has been growing at an annual average rate of 6.1 per cent over the past two decades and accounted for 43.1 per cent of global seafood production in 2013, up from 30.6 per cent in 1993. Aquaculture production is highly concentrated in the Asia-Pacific region, which accounts for an estimated 90 per cent of global production (Jonell, Phillips, Rönnbäck, & Troell, 2013). China alone accounted for 62 per cent of the world’s aquaculture production in 2013. In the face of stagnating production volumes in wild catch, aquaculture has almost single-handedly been responsible for meeting the global increase in seafood demand over the past decade. Following a similar path, certified aquaculture production has grown exponentially, at an average rate of 76 per cent per year from 2003 to 2015, significantly outpacing the growth of conventional aquaculture. Certified aquaculture is highly concentrated across a small number of countries, with Norway, Chile and Spain accounting for over half of the global total.
