The invention provides a hypothermic anesthesia transportation method for live Oncorhynchus mykiss, the method comprising following steps: 1) feed deprivation: food provisioning for Oncorhynchus mykiss is stopped for 2-3 days before transportation; 2) cooling and anesthesia treatment: water tanks are filled with cooled aquaculture water of 1-2 DEG C; the water temperature is maintained; anesthetic is added to the water and mixed well. The Oncorhynchus mykiss deprived of food is weighed and then put in the aquaculture water and quick cooling and anesthesia are performed. The Oncorhynchus mykiss is taken out of water surface when the activity ability of the fish is nearly exhausted. By this time, the fish bodies are in the state of hypothermic anesthesia and then they are to be encased. 3) the Oncorhynchus mykiss are transported by packing transportation or water track transportation. After arriving at a destination, The Oncorhynchus mykiss are brought back to life and the temperature of aquaculture water is gradually increased to normal level. The hypothermic anesthesia transportation method has following beneficial effects: no matter how much the transportation volume of live fish is, the transportation method can be performed with low cost, simple, flexible and easy operation; and the economic benefit can be guaranteed by high rate of survival of fish after transportation.
