Abstract: A method of transporting live fish is disclosed. The method comprises inducing in the fish a state of piscine immobility syndrome. Piscine immobility syndrome means the hypnotic-like, apparently behavioral, state in fish appear to assume a relaxed state. The state of piscine immobility syndrome is maintained in the fish while transporting the fish to the desired destination. It has been found that a state of piscine immobility syndrome can be induced by physically restraining the fish against substantial movement and supplying water of a particular quality to the fish.
