Abstract: | Population genetic structure of silver Prussian carp from the Middle Dnieper basin was established by means of biochemical
gene marking and cytometric analysis. In addition to diploid goldfish Carassius auratus, which was the basic species of bisexual colonies, a number of biotypes of triploid silver Prussian carp C. gibelio were identified. These biotypes either formed isolated unisexual populations, or were an admixture to the bisexual colonies.
In addition, in bisexual colonies, triploid females of non-clonal origin were identified. Despite the fact that all forms
of C. gibelio reproduced by means of gynogenesis, some of them (C. gibelio-1) formed isolated unisexual populations, while the others (C. gibelio-2, -3, and -4) usually coexisted with C. auratus. |
