The concentrations of polyamines in the tissues of five live fresh-water fishes were determined by gas chromatograph equipped with a flame ionization detector. Spermine (Spn), spermidine (Spd) and putrescine (Put) were distributed in the tissues in general; Spn was largest, followed by Spd, and Put was smallest in quantity. Loach Misgurnus anguillicaudatus was lacking in Spn and Put, and contained cadaverine (Cad) in the muscle and skin. Cad was also detected in the skin of eel Anguilla japonica. A large amount of Spn was determined in the spermary of carp Cyprinus carpio (103mg/100g). During the storage at 5°C, the level of Spn in the muscle of carp decreased gradually as decomposition progressed and that of Spd was almost constant. The levels of Put, Cad and tyramine increased remarkably after initial decomposition.
