Rainbow trout was one of the first species whose life cycle was fully replicated under farmed conditions. It can be farmed in a variety of systems, in many areas around the world and in both freshwater and seawater, making it one of the most popular species in aquaculture.

Globally some 814,000 tonnes of rainbow trout were produced in 2016, of which 609,000 in freshwater. Iran and Turkey accounted for more than 40% of the rainbow trout produced in freshwater, predominantly using systems such as flow-through ponds, while most of the marine-grown trout (84%) came from net-pens in Norway and Chile.
