ABSTRACT
Electrophoretic analysis ofSacroplasmic protein were performedfor
the species ofFamily mugilidae (MugU cephalus, Liza ramda and Liza
aurata) in marine andfresh water habitats. Genetic polymorphism and
coefficients of similarity were investigated in marine andfreshwater for
the studied groups.
This study revealed that sarcoplasmic proteins ofthe studied groups
are markedly conservative, this makes it possible to use them to study the
systematic relation between the species. Also this study revealed a close
coefficient of similarity between MugU cephals and Liza ramada.
Sarcoplamsic protein can be used to differentiate between the juveniles
ofmarine MugU cephalus and marine Liza ramada.
