Abstract Physicochemical changes of muscle from croaker, lizardfish, threadfin bream and bigeye snapper during storage at −18 °C were investigated for up to 24 weeks. Ca2+–ATPase activity decreased, whereas Mg2+–EGTA–ATPase activity increased throughout the storage. However, no marked changes in Mg2+–Ca2+–ATPase and Mg2+–ATPase activities were observed. Among all species tested, lizardfish muscle was most susceptible to those changes. Disulfide bond formation with the concomitant decrease in sulfhydryl group was found in all species. However, croaker and lizardfish contained higher disulfide bonds as storage time increased, compared to other species. Surface hyd...
