Schizothorax Chongi (fang), which is a fine -scale split -abdomen, is a unique species in my country.

>

Fine -scale cracked belly fish is successfully domesticated, and it is carefully cultivated. After the adrenal development is mature, artificial reproduction tests are conducted. From 2005 to 2006, the researchers used 4 different oxytic agents to combine more than 180 and mature wild fine-scale cracked fish (Schizo-ThHoraxchongi), an artificially domesticated, and manually oxytocummary. Gragon, incubated more than 90,000 tails. The combination of oxytoconis that has a good oxytic effect is: carp brain pituitary (PG) with human chorionic gonadotropin (HCG) combined with secondary injection. The injection dose is (12mg+1000IU)/kg fish weight, and the effect time is 85-98h at the water temperature of 13-18 ° C.

In the cracked belly fish, fine -scale cracking abdominal embryo develops faster, especially after the muscle effect period is more obvious. The heartbeat frequency is not simply a simple linear growth from slow to fast, but a fast and slow curve change change. In the process, the various periods of embryo development have different sensitivity to the environment, and the original intestinal period is the most sensitive to changes in the external environment.

Fine -scale cracking fish is suitable for the plateau and cold water climate. It grows slowly, has a low reproductive force, and has a large type of individuals. It takes 6 to 9 years to reach 0.5 kg. Generally, it takes 3 to 4 years to mature.

In December 2021, the Ministry of Agriculture and Rural Affairs was included in the third batch of "Artificial Breeding National Key Protection of Aquatic Wildlife".
