As global seafood consumption continues to rise, numbers of wild-caught fish have remained flat. The sourcing of these stocks is coming, increasingly, from fish farming, or aquaculture.
The amount of fish produced by aquaculture has increased exponentially over the last 50 years. By 2030, aquaculture is expected to supply just over 60 percent, or 186 million tons, of global seafood demand.
These fish farms, located both on and offshore, range from small, hand-tended ponds in emerging economies to large, professional operations run by huge corporations. But their goal is the same: cultivate fresh water or marine species in controlled environments to produce a reliable source of food. And they all have the same challenge: maintaining optimum fish farming conditions to promote healthy growth.
