The old man raised the baby fish for 4 years and was more than 1 meter long, why did the fish grow s

This happened in Kunming, Yunnan Province. A 96-year-old man who has raised a baby fish for 4 years, more than one meter long, is currently reluctant to eat it if he can't raise it, so he sent the baby fish to the zoo. Generally, the size of the baby fish can grow to more than one meter, and the longest can grow to more than two meters, so it is normal for this baby fish raised by the old man to grow to this size.

In our country, the wild baby fish is a protected animal and cannot be harmed, but the raised can be eaten, the old man is reluctant to eat it, and it can be seen that the old man is very caring when he sends it to the zoo.

Also known as the Chinese giant salamander, the salamander has been on Earth for hundreds of millions of years. They are called baby fish because their calls are similar to the cry of a baby. Although it is called a baby fish, it is not a fish, it is an amphibian.

Because their survival requires extremely high water quality, they generally inhabit streams below 1,000 meters above sea level. It is mainly distributed in the middle and lower reaches of the Yangtze River basin in China. However, in the face of human hunting and pollution of the natural environment, the habitat of wild salamanders is also slowly shrinking.

At present, although there are many artificial breeding of salamanders, the survival of wild salamanders is also facing big problems. The baby fish have a cute appearance and four small short legs, which also makes their migration ability very weak, and they will become extinct in this place when the water source and environment of the living place are polluted and destroyed. The scarcity of wild salamanders is mainly due to factors such as overfishing by humans and environmental damage.

China has also made certain protection measures for the current situation of salamander. The construction of protected areas, the enhancement and release of salamanders, and the promotion of ecological breeding of salamanders are all making certain contributions to the development of salamanders. And we should also make our own contributions, caring for the environment, not poaching and killing, etc., can help them survive.

The baby fish is very cute, and the baby fish that the old man has raised for four years is reluctant to eat and finally sent to the zoo to be even more cute. Because of the harmonious survival of humans and animals, the diversity of biological species can also make the earth more colorful. One final word:

Wild salamanders are protected animals and are not allowed to be eaten.

1. This is a normal growth cycle. The scientific name is giant salamander, which is an amphibian of the class and the family of cryptogill salamanders, living in fresh water, but it is not a fish, but the largest amphibian, the body length is generally about 1 meter, the longest can reach 2 meters, the weight is 20-25 kg, and the largest is 50 kg.

Second, the reason why the fish can grow so big is that the old man usually pays great attention to the maintenance of the fish, which has a lot to do with the careful care of the old man.

Because the baby fish itself can grow very big, and this old man is very precious to this baby fish, so he will feed this fish very big.

Because the old man took good care of it, gave it good food every day, prepared a fish tank for it, and took care of it every day like a pet, so this baby fish grew very big.

It takes 5 years for the baby fish to grow to 15 catties.

The growth cycle of the baby fish is very long, the baby fish belongs to the oviparous, generally hatched after 30-40 days of juvenile baby fish, it takes 3-5 years to reach the maturity stage, calculated by a baby fish, a year is about a catty, if it is artificially farmed, it may grow to about 3 catties a year, and 20 catties of baby fish will grow for about 7 years.

Farming techniques

The water temperature for breeding should be suitable. According to many years of observation, the most suitable water temperature for the growth of salamander is 16 22 . In the low mountain summer, the temperature is high, and if the water temperature exceeds 26, the growth of the salamander will be affected, and sometimes the phenomenon of "summer hibernation" will occur, and too high the temperature will also cause the salamander to die.

However, if the altitude is too high, the ambient temperature and water temperature are too low, the effective growth time of the salamander is short, the growth rate is slow, and the breeding is not cost-effective. Therefore, it is best to choose an area at an altitude of 500 800 meters above sea level, where there is no severe cold in winter and no heat in summer.

The water quality of aquaculture should be good. The baby fish likes to be clean and afraid of dirty, and has very strict requirements for the water quality of the environment. Wild salamanders generally inhabit deep mountains, canyons, streams and rivers with good natural vegetation, pollution-free environment, and little human involvement.

Artificially bred baby fish in mountainous areas, the best water source is to choose a small stream and ditch with perennial flowing water, spring water, and the bottom water of large and medium-sized reservoirs with fresh water quality can also be used, in short, the water quality should be fresh, fresh, pollution-free, the dissolved oxygen content is high, and the pH value is neutral. Some of the chemicals in the water flowing from farmland and mines in mountainous areas and urban tap water may exceed the standard, and cannot be used as water for the cultivation of baby fish.

The salamander has a long lifespan among amphibians, which can live for hundreds of years, and some can reach 130-200 years.

When you are young, you use your gills to breathe, and when you grow up, you use your lungs to breathe. Baby fish inhabit mountain streams and live in caves with clear water, low sand content, strong currents and backflow water.

The giant salamander also has the longest lifespan among amphibians, living up to 130 years in captivity.

The oldest baby fish in the world, which has lived for more than 200 years and is 2 meters long, lives a retirement life in our country.

The salamander is lifespan 50 to 60 years.

Baby fish are amphibians that live in freshwater. It is a precious wild animal that is a specialty of China, because its night cry is like a baby's cry, so it is commonly known as "baby fish", but it is not a fish, but the largest amphibian;

It can breathe with its lungs, but because the lungs are not well developed, it is also like a frog, which needs to use moist ** for gas exchange as an auxiliary breathing, so it must live in water or near water.

The body length is generally about 1 meter, the longest can reach 2 meters, the weight is 20-25 kg, and the largest is 50 kg. The body color varies according to the color of the habitat, and the back is brown, reddish-brown, black-brown, etc., with dark irregular spots on it, and the ventral surface is light brown or grayish-white.

The giant salamander, whose scientific name is "giant salamander", is the largest species of the surviving order and can reach a length of more than 1 meter. It belongs to the national second-class protected animal, is the largest existing amphibian, the nutritional value of the baby fish is extremely high, known as "water ginseng". In the Xia Dynasty document "Overseas Western Longitude", the salamander is called the arowana, and the salamander has a longer lifespan among amphibians, which can survive for hundreds of years.

Remember to adopt it.

50-60 years, some salamanders can live for 100-120 years, when long-lived aquatic animals. Seek adoption.

200-year-old because of Zhangjiajie, there is a 200-year-old baby fish.
