The ATPase activities and proteolysis of myofibrils from pre‐ and postspawned flounder stored on ice were studied. At zero time of storage, no significant differences ( P > 0.01) were observed in the Mg 2+ Ca 2+ and Mg 2+ (EGTA) ATPase activities of pre‐ and postspawned flounder myofibrils. No significant changes ( P > 0.01) were observed thereafter in both enzymatic activities of postspawned myofibrils. Conversely, a significant decrease ( P < 0.01) in the Mg 2+ Ca 2+ and Mg 2+ (EGTA) ATPase activities occurs in myofibrils from prespawned fish during storage. No significant changes ( P > 0.01) in the Ca 2+ sensitivity and no evidence of proteolysis were detected in myofibrils from pre‐ and postspawned fish stored on ice.
