White dorsal muscles excised freshly from carp and rainbow trout were stored at 0 and 20°C, and protein degradation patterns were analyzed by SDS-PAGE.<br> It was revealed that α-actinin in carp muscle decreased with concomitant formation of a fragment within 3 days storage at 0°C. At the same time, carp myofibrils became to be fragmented. In rainbow trout muscle, α-actinin was not cleaved at all over the storage period of 4 days even at 20°C, but slowly increased in solubilization. The fragmentation of rainbow trout myofibrils pro-ceeded slowly.<br> α-Connectin was completely cleaved into β-connectin and a 400 kDa fragment within 2 and 4 days storage at 0°C in carp and rainbow trout muscles, respectively. At 20°C, the disappearance of α-connectin was remarkably accelerated in both muscles.<br> In postmortem fish muscle, it was suggested that disintegration of the structure of myofibrils might progressively proceed by the following successive reactions: first of all, the cleavage of α-connectin occurred and followed by solubilization and degradation of α-actinin and change in nebulin, and then β-connectin and troponin were degraded. The major proteins of the myofibrils (myosin, actin, and tropomyosin) remained unchanged.
