The tench Tinca tinca is a freshwater species with human-mediated translocations, aquaculture interest and limited information on its genetic structure. mtDNA sequencing analysis of control region and two genes in 50 individuals from five European populations identified two phylogroups, with greater variability than that reported until now, and a hybridization zone in the Danube River region. Restriction analyses of additional samples reveal the complicated genetic structure characteristics of tench's wild and translocated populations, supporting future breeding practices.

tench Tinca tinca欧洲种群的遗传结构和分化

丁鱼 Tinca tinca 是一种淡水物种，具有人类介导的易位、水产养殖兴趣和有限的遗传结构信息。对来自五个欧洲种群的 50 个个体的控制区和两个基因的 mtDNA 测序分析确定了两个系统群，其变异性比迄今为止报道的更大，以及多瑙河地区的一个杂交区。额外样本的限制性分析揭示了丁香野生和易地种群复杂的遗传结构特征，支持未来的育种实践。
