SUMMARY The influence of feeding, activity and pasteurizing doses of gamma irradiation on the nucleotide composition and breakdown in English sole ( Parophrys vetulus ) was studied. Feeding did not cause any significant change in the total amount of nucleotides. Active fish had lower amounts of ATP and increased levels of IMP, but this difference was not significant after they had been stored 7 days in ice. In contrast to the results reported for other species of sole, inosine was present in English sole after 7 days in ice. Irradiation, 0.5 and 1.0 Mrad, did not affect the changes in the nucleoside and nucleotide composition.
