What's the name of foreign fish?

This kind of fish is also called Yayu, Ice Snow and Jiayu.

Exotic fish, scientific name Schizothorax, has Schizothorax, with red tail, looks like carp and scales like trout. Foreign fish are delicious and have high nutritional value, but because they are very rare in the market, the price is relatively high. I like to live in fresh water, flowing water, abundant water, gravel geology and cold water in limestone formations. The origin is generally distributed in the Qinghai-Tibet Plateau and its surrounding areas.

Because of the long freezing time in winter in mountainous areas, even in summer, the water temperature is very low, so Schizothorax fish often live on omnivores, which gradually degrades the scales of the body, reduces the number of rows of swallowing teeth, and disappears due to the loss of function. Schizothorax fish living in this harsh environment grow slowly, mature late and have low fecundity. Larger varieties take 6-9 years to reach 0.5 kg, and generally take 3-4 years to mature.
