An analysis of 30 presumptive enzyme loci and 7 meristic characters has been used to study different populations of the cyprinid Leuciscus (Telestes) soufia. This fish is considered autochthonous in south-eastern France, with 3 described sub-species. The estimates of gene diversity were similar to results from studies on Cyprinidae from North America. The sample from the upper reaches of the river Durance showed higher levels of gene diversity; heterozygosity and percentage of polymorphic loci than all other samples. Furthermore, the samples from the Durance, as a whole, seem to embrace a population with little or no subdivision. Six of the 7 measured meristic characters yielded no significant differences between samples. The population sample of the sub-species soufia from the river Var differs from the other samples only by allele frequencies, low level of heterozygosity and the number of gill rakers. It is argued that these characters are quite insufficient and may cast doubt as to the validity of the subspecies rank of this population.
对30个假定的酶位点和7个可数性状进行了分析，以研究鲤科鱼类索氏雅罗鱼（Leuciscus (Telestes) soufia）的不同种群。这种鱼在法国东南部被认为是本地种，有3个已描述的亚种。基因多样性的估计结果与北美鲤科鱼类的研究结果相似。迪朗斯河上游的样本显示出比所有其他样本更高的基因多样性水平、杂合度和多态位点百分比。此外，迪朗斯河的样本总体上似乎包含一个几乎没有或没有细分的种群。7个可数性状中有6个在样本之间没有显著差异。来自瓦尔河的soufia亚种的种群样本与其他样本的不同仅在于等位基因频率、低杂合度和鳃耙数量。有人认为，这些特征相当不足，可能会让人怀疑该种群亚种等级的有效性。
