Application of allozyme markers for screening of turbot populations along Western Black Sea coast
Data for electrophoretic pattern of 26 loci, resolved for the 8 protein systems (7- enzyme and 1-non-enzyme) assayed were used to investigate population structure of turbot along the Bulgarian and Romanian Black Sea coasts using genetic diversity measures. Seventeen loci were polymorphic in all popu...
