摘要
鲈鲤（Percocypris pingi）是长江上游特有珍稀鱼类。2011年6-8月,从长江上游支流雅砻江冕宁江段收集34尾鲈鲤,测定其线粒体控制区（D_Loop）序列以评估其遗传多样性。结果显示,D_Loop序列全长933-934 bp,34个D_Loop序列中定义了7个单倍型,12个多态位点,种群平均单倍型多样性Hd=0.082 0±0.042 0,核苷酸多样性Pi=0.003 6±0.000 4,说明鲈鲤种群遗传资源不丰富,结构简单。
The Percocypris pingi is a rare and endemic species , which only inhabits the upper reaches of the Yangtze River.From June to August , 2011 , 34 individuals were collected from Mianning sections of Yalong River , the tributary of the Yangtze River.All sequences of the mitochondrial control region （ D_Loop） in full length 933-934 bp were used to evaluate the genetic diversity.The results showed that 7 haplotypes and 12 polymorphic sites were found .The haplotype diversity , nucleotide diversity were 0.082 0 ±0.042 0 and 0.003 6 ±0.000 4 , respectively.Due to current dam construction and overfishing P.pingi formed small population in Yalong River .The population genetic resource was not rich and the population genetic structure was simple .The artificial propagation and releasing of P.pingi is an effective method for stock recovery .
