Lenok

Lenok

 

(Brachymystax lenok), a fish of the family Salmonidae. The body measures up to 70 cm long and weighs up to 8 kg. It is found in the rivers and mountain lakes of Siberia and the Far East, as well as in western Korea. It has a smaller mouth than other salmon. The lenok reaches sexual maturity when it is four to six years old; its reproductive capacity is up to 12,000 eggs. The fish feeds on invertebrates (mollusks, caddisworms, the larvae of ephemeras) and some small fishes (minnows, gudgeons, graylings, and miller’s-thumb). In the Amur basin in autumn, the lenok eats the eggs of the dog salmon and pink salmon; in the spring it eats their fry. Thus, this fish does some damage to the fishing industry. The lenok has little commercial value.

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.

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.
