A cooling process for live salmon from breeding cages in the sea, using a cooling mixture consisting of ice and common salt in fresh water that is placed in a cooling tank mounted on a truck for the transport of the fish, wherein the process is constituted by the following steps:a) The input of the fish into the cooling tank, without transferring the seawater in which they were bred, which is at a temperature between −0.7 to −3.9° C. to cause their unconsciousness； andb) The transportation of the fish at this temperature to the slaughter plant.This cooling process for live salmon respects the bioethical norms for achieving the death of fish with reduced suffering after rapidly inducing unconsciousness, allowing the production of high quality products.
