Rainbow trout, as a cold-water farmed species of fish in the genus Pacific salmon of the salmon family, is favored for its extensive farming value. In the market, rainbow trout usually sells at a stable price of around $36 per pound. However, the price may fluctuate depending on regional differences. For example, in Beijing's Fengtai District Xinfadi Agricultural Products Wholesale Market, rainbow trout is quoted at RMB 39.0 a kilogram, while in Tongzhou Baliqiao Agricultural Products Center Wholesale Market, the price is slightly higher at RMB 43.0 a kilogram. In the northwestern Urumqi Beiyuanchun Wholesale Market, the price of rainbow trout is relatively more affordable at 33.0 yuan a kilogram. Therefore, when buying rainbow trout, consumers should refer to the market price in their own region.
