What are the key points of artificial breeding technology for the Chinese giant salamander?
The Chinese giant salamander, also known as the Chinese giant salamander, is an amphibian wildlife species unique to our country. It is called this name because its call sounds like a baby crying. The Chinese giant salamander is not a fish, has a relatively large body size, and its body color can change with changes in the external environment. Because wild Chinese giant salamanders are national second-class protected animals, artificially bred ones are also relatively common. Below, let us take a look at the key points of artificial breeding technology for the Chinese giant salamander.
I. Choosing a suitable environment
Water temperature: The optimum growth water temperature for the Chinese giant salamander is between 16~22°C. In low-altitude areas, when the water temperature exceeds 26°C, the Chinese giant salamander will show “summer dormancy”, thereby causing restricted growth. Excessively high water temperature may even cause the death of the Chinese giant salamander. In high-altitude areas, if the temperature is too low, the growth of the Chinese giant salamander will also be affected, the growth rate will slow down, and breeding efficiency will be affected, making it unprofitable. Therefore, the site for breeding Chinese giant salamanders is generally chosen at an altitude of 500~800 m, in a place where winter is not especially cold and summer is not especially hot.
Water quality: The Chinese giant salamander has very high requirements for water quality. Wild Chinese giant salamanders like to grow in deep mountain streams and lakes with abundant vegetation, an unpolluted environment, and far away from humans. Therefore, artificial breeding of Chinese giant salamanders is best carried out in mountainous areas, in small streams or mountain springs with flowing water. Of course, good water quality is a necessary condition. For example, low-layer water from some large and medium-sized reservoirs with good water quality, no pollution, and high dissolved oxygen content is also acceptable.
II. Scientifically and reasonably building ponds
Breeding Chinese giant salamanders requires separate breeding according to size, and many small ponds can be built for breeding. Breeding ponds generally adopt a brick-concrete structure. There are ponds of different sizes according to the size of the Chinese giant salamander, and the pond walls must be smooth.
Set water inlets and outlets at both ends of the pond, with each pond's water inlet separately connected directly to the main water inlet pipe.
III. Stocking seedlings
Purchasing seedlings: Healthy fry from artificial breeding can be purchased nearby. Generally, fry of 1 liang or more are selected, as such fry are easier to survive and grow quickly.
Stocking seedlings: Chinese giant salamanders are fierce and fond of fighting. In particular, large adult ones will bite and fight over food, and may even bite small fry to death. Therefore, they should be stocked and bred separately according to size.
IV. Feeding management
The Chinese giant salamander is not a picky eater. For example, it eats fish, shrimp, crabs, loach, frogs, earthworms, insects, and even the internal organs of cattle, sheep, pigs, and chickens. Moreover, the Chinese giant salamander is very resistant to hunger. Even if it does not eat for a long time, it will not starve to death. However, if food is insufficient, Chinese giant salamanders will fight among themselves.
V. Key points of daily management
Keep the water clean and fresh. It should be flowing water, free of pollution, with high dissolved oxygen content and a moderate water volume. Avoid drying up due to too little water, and also avoid overflowing due to too much water, which could allow the salamanders to escape.
Control the water temperature, especially in hot weather, and keep the water temperature no higher than 25°C.
Pay attention to shading, build a shade shed, and avoid strong light exposure.
Prevent escape and theft. There is a lot of rain in summer, so prevent excessive water volume and overflow, which could lead to Chinese giant salamanders escaping.
