Summary

Major and early molecular changes specific to sea-bass post mortem muscle, and probably to other fish species as shown with dorado, are very fast degradation of dystrophin and titin and slow release of alpha-actinin. These changes induce breaks in links of microfibrils to collagenic matrix, in elastic filaments and Z-disks. Total disappearance of dystrophin 48 hours after fish death or 8 hours after thawing may be helpful to judge quality of stored fish products.
