Genetic characterization of the endangered Brachymystax lenok
tsinlingensis (Salmonidae) populations from Tsinling mountains in China using microsatellite markers.
Educational sessions featured an update on the state of the domestic economy and markets from Mark Williams of Brown Brothers Harriman; a presentation on the danger of not managing price risk by Julio Sera of INTL FCStone, which discussed the negative effect on profitability caused by elevated levels of coffee price volatility; and a review of the 2010 INCO Terms and the changes made from the 2000 INCO Terms, by Neil Lenok
of American River Group of Companies.
Her Masters thesis was a study of the early development of Brachymystax lenok
. At Hebei University Fang worked as graduate assistant and associate lecturer in vertebrate zoology.
There is a good chance they were lenok
, a kind of trout native to the Korean peninsula and the coldwater streams that flow through the DMZ.
lenok tsinlingensis had wider and elongate head, the longest eye diameter and the widest dorsoventral orientation; B.
Based on comparing some characters of specimens from two geographical populations (the Amur River and the streams of Qinling Mountains), such as number of gill rakers, lateral-line scales and pyloric caeca, Li (1966) considere that the Brachymystax fish distributed in the Qinling differ from that of Amur River, and described it as an endemic subspecies, and named as Brachymystax lenok tsinlingensis Li.
lenok tsinlingensis populations in the wild (Ren and Liang, 2004), and rare fish can be found in the brook of the Qinling Mountains where far away from human activities, only in the region with altitude range from 1100 m to 2300 m (Yue and Chen, 1998; Ren and Liang, 2004; Gong et al., 2009).
lenok tsinlingensis Li, 1966 (Qinling lenok) was described as a subspecies differ from B.
Brachymystax lenok tsinlingensis (Salmonidae) is an indigenous and endangered cold-water fish in Tsinling mountain, China, and only is distributed as spot in the Weihe River and Hanjiang River among Tsinling mountain, To access relationship of populations from the two rivers and the genetic diversity of wild population, 11 microsatellite loci were firstly used to evaluate the genetic characterization using 120 samples from 2 tributaries (ZZ and LX populations) of the Weihe river and 2 tributaries (YX and TB population) of Hanjiang river.

Brachymystax lenok tsinlingensis (Qinling lenok), as a critically endangered salmonid fish, is only found in Weihe and Hanjing Rivers tributaries(cold freshwater) in Tsinling Mountains, China (Sze-Chung, 1966).
lenok tsilinlingensis is one of two Salmonidae located in the southernmost part of China (the other is hucho taimen) (Xia et al., 2016; Wang et al., 2016).
