Post-mortem degradation of the muscle tissue in diloid and triploid turbots (Scophthalmus maximus L.)
Structural and ultrastructural muscle changes were studied throughout post-mortem degradation in diploid (2N) and triploid (3N) 22-month-old turbots (Scophthalmus maximus L.). Textural changes were also studied. Muscle degradation was fast in 2N and 3N turbot, as indicated by detachment of myofibril...
