As wild fish stocks are at “dangerously unsustainable levels” the aquaculture industry is expected to supply 60% of the world’s fish in the next eight years. In the past five years, fish consumption grew 14.4% and in 2011 reached a record 154 million tons. To maintain the current levels of consumption, aquaculture will need to produce an additional 23 million tons of farmed fish by 2020.
