Genetic diversity among 10 populations of gibel carp Carassius gibelio in Bulgaria were analyzed using general muscle proteins and five enzymes encoded by 16 loci as markers. All of the six systems investigated indicated polymorphism and nine polymorphic loci - PROT-3*, EST-1*, EST-2*, sMDH-2*, sMDH-3*, mMEP*, sMEP*, LDH-B*1 and SOD* were detected. These loci were encoded by codominant alleles and their inheritance patterns were analyzed. The gene frequencies of polymorphic loci can be used as genetic markers for distinguishing of gibel carp populations in Bulgaria. The analyses of genetic distances between the populations of C. gibelio indicated a natural dispersal and/ or deliberate introduction of this invasive species from the Danube River basin to the other inland water bodies in Bulgaria.
