In this study, SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) was applied to the sarcoplasmic proteins of Orthrias insignis euphyraticus (BALITORIDAE) and Cyprinion macrostomus (CYPRINIDAE) fish taken from Karakaya Dam Lake. The electrophoregram showed that there were differences between the two species in both the number of bands and the molecular weight (MW) of the sarcoplasmic proteins. While Cyprinion macrostomus had 18 protein bands, there were 20 protein bands in Orthrias insignis euphyraticus. On the other hand, the bands obtained from Orthrias insignis euphyraticus and numbered as 9th protein band with molecular weight of 29.5 kD and 12th band with MW of 27.2 kD were not found in Cyprinion macrostomus. 9th protein band with MW of 27.5 kD was only found in Cyprinion macrostomus. We concluded that comparisons of sarcoplasmic proteins might have practical importance in taxonomic classification.
