The changes of silver carp muscular proteins during chilled storage at 0℃ and 4℃ for 14 days were studied using SDSPAGE and western blotting. The result showed that the degradation tendency of sarcoplasmic protein was not obvious and comparable under these two temperatures. Among myofibrillar proteins, obvious degradation of myosin heavy chain （MHC） was observed after 14 days at 0℃ and 11 days at 4℃, respectively. Gradual degradation of α-actinin and actin was detected under both temperatures, and it was more obvious at 4℃. The degradation of tropomyosin could be observed after 2 days both at 0℃ and 4℃. Similar to MHC and actin, tropomyosin degraded significantly at 4℃ after 11 days.
