According to figures from the United Nations Food and Agriculture Organization, around 1980 only 9% of the aquatic products consumed by humans came from aquaculture, but that figure rose to 20% in the 1990s and stood at 44% in 2010. It is estimated that by 2030, aquaculture will supply a majority of the world’s seafood. As the planet faces the exhaustion of ocean resources, net-cage aquaculture may take the place of marine fisheries.
