Summary Isoenzyme patterns and the polymorphism of lactate dehydrogenase (LDH) were investigated in 3 fish species of family Cyprinidae, i.e. tench ( Tinea tinea ), crucian carp ( Carassius carassius ) and carp ( Cyprinus carpio). The isoenzyme patterns were tissue and species specific. In crucian carp subunits with different electro‐phoretic mobility are present, which are genetically controlled from the B 1 , B 2 , A 1 , A 2 and C loci, while the set of loci in carp is B 1 , B 2 , A, C 1 and C 2 and in tench B, A, C. The locus B of LDH in tench, the locus B 2 in crucian carp, and the loci B 1 , C 1 and C 2 in carp are polymorphic and have two different alleles in each case. The polymorphism did not affect the total LDH activity in the tissues. All the populations investigated were in Hardy‐Weinberg equilibrium. The genetic control of the polymorphism in B 1 and C 1 loci in carp was proved by test matings. The polymorphism in B loci tested in erythrocytes may be utilized as genetic markers in the fish breeding.
