Abstract

We performed the comparative study on changes of cytochemical Mg2+-adenosine triphosphatase (Mg2+-ATPase) activity and its localization caused by a decrease in freshness of white (W), pink (P), and red (R) muscles in cultured carp during storage in ice. The contents of ATP-related compounds in the three muscle types were higher in the order of R>P>W, and the increasing of K value was faster in the order of R>P>W. Mg2+-ATPase activity was found on the A band of myofibril, sarcoplasmic reticulum and mitochondria menbrane/crista in each muscle type at just after killing. The deactivation of Mg2+-ATPase activity in these organella was faster in the order of R>P>W during storage period. The interposition of pink muscle fibers into the dorsal ordinary muscle might accelerate the deterioration of fish mucle in post-mortem.
