Ocean fish, its scientific name is Schizothorax, with a split belly and a red tail. It looks like a carp and has scales like a trout. Foreign fish is delicious and has extremely high nutritional value. However, because it is very rare on the market, its selling price is relatively high. It likes to live in cold water with fresh water quality, flowing water, sufficient water volume, gravel geology and limestone rock formations. The origin is generally distributed in the Qinghai-Tibet Plateau and its surrounding areas.

Because mountainous areas freeze for a long time in winter and the water temperature is very low even in summer, Schizothorax mostly lives in seclusion and eats omnivores. As a result, the body scales gradually degenerate, the number of tooth rows in the hypopharynx tends to decrease, and the oral palps are also lost. function and disappear. Schizothorax living in this harsh environment grows slowly, matures late, and has low fecundity. For larger species, it takes 6-9 years for the weight to reach 0.5 kg, and it usually takes 3-4 years for them to mature.
