The world’s appetite for seafood is growing and the wild capture of it is declining. How does a global demand for seafood get satisfied when the ability to capture wild stocks decline? Aquaculture steps in to feed the world’s insatiable demand for seafood. Total global fish production, including both wild capture fish and aquaculture, reached an all-time high of 154 million tons in 2011, and aquaculture is set to top 60 percent of production by 2020. Humans ate 130.8 million tons of fish in 2011. The remaining 23.2 million tons of fish went to non-food uses such as fishmeal, fish oil, culture, bait, and pharmaceuticals. The human consumption figure has increased 14.4 percent over the last five years. And consumption of farmed fish has risen tenfold since 1970, at an annual average of 6.6 percent per year. Asia consumes two thirds of the fish caught or grown for consumption. Wild fish stocks are at a dangerously unsustainable level. As of 2009 57.4 percent of fisheries were estimated to be fully exploited, meaning current catches were at or close to their maximum sustainable yield, with no room for further expansion. Of the remaining fisheries in jeopardy, around 30 percent were deemed overexploited, while a little less than 13 percent were considered to be not fully exploited. To maintain the current level of fish consumption in the world, aquaculture will need to provide an additional 23 million tons of farmed fish by 2020. To produce this additional amount, fish farming will also have to provide the necessary feed to grow the omnivorous and carnivorous fish that people want. Aquaculture is being pressured to provide both food and feed because of the oceans’ overexploited fisheries.
