Abstract

Study of population structure of crucian carps in the mixed forests zone of Northern Ukraine (characterized by ample diversity of unregulated aquatic systems) showed the presence of diploid C. сarassius and C. auratus, triploid C. gibelio (represented by a series of clones), C. auratus x C. сarassius diploid hybrids, and tetraploid hybrids between C. сarassius and C. gibelio. The crucian carps of the region compared with those of more southern zones of Ukraine are characterized by numerical prevalence of unisexual form of С. gibelio, and relatively restricted hybridization of C. сarassius and C. auratus.
