The Shuizuxiang-Class is a special type of vessel for transportation of live fish, especially for salmon. This vessel type is used in aquaculture for transporting the fish stock from farm to factory. A live fish carrier is equipped with tanks or wells for the storage of fish during transportation. The fish stock is pumped from the farm site and onto the vessel and again from the tanks and into the processing factory.
