Population-Genetic Structure ofBarbus Cyclolepis(Pisces, Cyprinidae)

In the paper 25 samples of Barbus cyclolepis group from River Strumica, (Macedonia), 18 samples from river Marica and 2 samples from reservoir Dospat, (Bulgaria), and 5 samples from River Pinios (Greece) were investigated. General muscle proteins (miogens, sarcoplasmic proteins) and six enzymes (AAT, EST, MDH, LDH, ME, SOD) were electrophoreticaly analyzed. Based on protein starch-gel electrophoresis and isoelectric focusing (IEF) on thin polyacrilamide ampholine gel, intraspecies difereneses among populations of Barbus cyclolepis group from investigated localities were detected.
