An overall fluorescence increase was obtained as a result of increasing storage times and temperatures. A fluorescence shift to higher wavelength maxima was observed according to previous results obtained from heat-treated fish muscle ( cooking and sterilisation). Shift values were not so high in the present experience as were in the case of thermal treatments, although fluorescence ratio between two excitation/emission maxima (393/463 and 327/415 nm) showed a good correlation with thiobarbituric acid (TBA) values at -20°C and -10°C (r = 0'9411 and 0'9553, respectively), and with total volatile bases (TVB) values at 0°C (r = 0'9264)
