摘要

The polyspecies structure has been described for Carassius spp. inhabiting the water bodies of Ukraine. Analysis of 133 populations revealed that 62% of 3453 studied individuals were diploid goldfishes C. auratus, 25% were triploid Prussian carps C. gibelio, 6% belonged to the aboriginal diploid species of crucian carp C. carassius, and 6% were the diploid and triploid hybrids C. auratus x C. carassius. The alternative homogenous populations of either C. auratus or C. gibelio tend to form strongly. In these populations, the individuals of C. carassius and the hybrids C. auratus x C. carassius typically comprise an admixture in various populations. The instability of mixed populations may be named as one of the reasons of the bipolar distribution of the individuals of C. auratus and C. gibelio in various water bodies, because C. auratus very quickly replace females of C. gibelio due to the low reproductive potential of the last species.
