Influences of storage temperatures on the prolongation of <i>pre-rigor</i> period of sea bream <i>Pagrus major</i> were examined. The amounts of ATP in the muscle of sea bream decreased more rapidly and <i>rigor mortis</i> proceeded faster at 0°C than at 10°C. In the muscle stored at 10°C the onset of <i>rigor mortis</i> occurred seven hours later than at 0°C. The formation of lactic acid in the muscle of sea bream was parallel with the development of <i>rigor mortis, i.e.</i>, the large amounts of ATP supplied through glycolysis were considered to be used as the contraction energy. K value as the index of freshness at 10°C was twice as high as at 0°C, however, after 48h of storage at 10°C it was below 10% which is thought to be very fresh. The production of inosinic acid during the storage at 0°C was more prompt than at 10°C. The decrease in ATP amounts was also examined in the muscle of plaice <i>Paralichthys olivaceus</i> stored at -3°C, 0°C, 5°C and 10°C. At -3°C and 0°C ATP decomposed very rapidly, followed by 5°C and most slowly at 10°C.
