It is illegal to raise wild salamander without permission. The economic value of salamander is relatively high, and people's overfishing for food is becoming more and more serious, coupled with river pollution and ecological environment destruction, resulting in a sharp decline in the number of giant salamanders, and the depletion or even extinction of resources in many places. In order to protect this resource, China has listed the giant salamander as a second-class key protected wild animal and strictly prohibits hunting.

Chinese giant salamanders in different waters, the food is also slightly different, they eat a large amount, mainly prey on fish, crustaceans, amphibians and small arthropods in the water, in addition to a small amount of plant components found in the stomach of giant salamanders. Living in the habitat of the giant salamander in the Yangtze River Basin, there are white turtles, broad-mouthed glossy lipfish, horsemouth fish and other fish, which provide a wide range of predation objects for giant salamanders.

Giant salamanders have poor eyesight, mainly through smell and touch to perceive external information, they can also sense the vibration in the water through the warts on the **, and then capture the food in the water.

Giant salamanders like to prey on crabs, and an individual weighing kilogram has 6 crabs in its stomach, with a total weight of about 140 grams; Kilograms of specimens can swallow 250 300 grams of food at a time; A giant salamander weighing more than 1 oyster was found in Mabian County, Sichuan, and there was a fish weighing 1 kilogram in its stomach.

Giant salamanders feed on fish and crustaceans at night, but due to poor eyesight, they can only detect changes in water pressure through their head and body perceptions to hunt prey. During mating season, giant salamanders swim upstream, and after the eggs are fertilized, males protect the young salamanders for at least six months until they are able to hunt on their own.

Baby fish eat a wide variety of foods;

The salamander is an amphibian that eats fish, shrimp, crabs, frogs, and aquatic insects. This animal has a wide mouth, sharp and dense teeth, and a strong bite, so it is often difficult for the other party to escape after biting the prey. Moreover, its metabolism is slow, and it can digest food for half a month after eating it once, and sometimes it will not starve to death even if it does not eat for more than a year.

There are no taboo people for salamanders. Baby fish is suitable for: 1. Pregnant women:

Pregnant women have a great need for nutrition during pregnancy and postpartum, and the nutrition of the mother during pregnancy is very important for the growth and development of the baby; The postpartum period is the weakest period of the human body's qi and blood, the nutrition in the confinement is very important for the mother, to drink more soup, can also play a role in promoting milk, at this time to drink a cup of soup stewed with baby fish is the best for the mother. 2. People with weak constitution, low immunity and sub-health: the immune system is the body's defense system against the invasion of viruses and bacteria; If a person's immune system is out of order, it can lead to symptoms such as physical weakness, malnutrition, fatigue, decreased appetite, and sleep disturbances.

3. Tumors and cancer patients: Because cancer itself is a wasting disease, coupled with the great damage during surgery, radiotherapy and chemotherapy often cause gastrointestinal reactions such as loss of appetite, vomiting, diarrhea, etc., which seriously affects the absorption and utilization of nutrients, so that the patient's nutrition is lower than the body's needs, resulting in the body's emaciation and weakness, the decline of disease resistance, and finally cachexia (medically refers to the phenomenon of systemic failure such as significant emaciation, anemia, and mental exhaustion of the human body, which is mostly caused by cancer and other serious chronic diseases). At this time, nutritional conditioning plays an extremely important role in the patient's **.

Baby fish is an animal with high edible value, its meat is delicate, delicious, contains high-quality protein, rich amino acids and trace elements, and has high nutritional value, known as "water ginseng", and is regarded as a rare supplement in Hong Kong, Taiwan and Southeast Asia. Giant salamander muscle protein is a high-quality protein with high content of essential amino acids and a good proportion of composition, which is fully in line with the human demand pattern, and its nutritional value is far better than that of abalone, bird's nest, shark fin and soft-shelled turtle. The muscle protein of salamander is rich in 18 kinds of amino acids, of which 6 kinds of flavor amino acids account for % of the total amino acids, 8 kinds of essential amino acids account for the total amount of amino acids, and the ratio of essential amino acids to non-essential amino acids is %, all of which are in line with the ideal model of FAO WHO. The giant salamander has a high score of essential amino acids, which is quite in line with the human demand pattern, and it is rich in lysine, which is easily lacking in China's staple food, which can be reasonably combined with staple food to play a complementary role in protein.

Baby fish can be eaten if it is bred in captivity. Generally, baby fish are virus-free. Because the cry of this animal at night is like a baby's cry, it is commonly known as a baby fish, but it is not a fish at all.

Baby fish can be eaten with confidence, but it must be cooked and cooked thoroughly. Because even if the virus is present, it will be killed by high temperatures.
