Tips: Chinese sturgeon belongs to wild protected animals. Protect wild animals from themselves, refuse to buy and sell wild animal products, and do not interfere with the free life of wild animals. At present, the consumption of precious and endangered wild animals in society is not only a bad social atmosphere, but also one of the reasons why illegal hunting and killing of precious and endangered wild animals are repeatedly prohibited. If you don't buy or sell, you won't be killed. Put an end to eating wild animals. They don't belong to the table.
First, the breeding conditions of Chinese sturgeon
1, water temperature
The adaptability of Chinese sturgeon to water temperature is quite extensive, and it can quickly adapt to various water temperatures. Under artificial breeding conditions, the optimum breeding temperature of Chinese sturgeon is about 20℃. Water temperature plays an important role in the growth of Chinese sturgeon, especially in the production period and incubation period.
2. Water quality
Under the condition of artificial culture, the water in the pond should be at least 50 cm transparent. Acipenser sinensis cannot grow in acidic water, so the Ph value of water should be controlled at around 7.5. In addition, the feces and garbage of Chinese sturgeon should be cleaned up in time to avoid polluting the water quality, and the number of plankton should also be controlled, otherwise the plankton will also pollute the water quality.
3. Dissolved oxygen
Acipenser sinensis has a very high requirement for dissolved oxygen in water, which is generally above 5mg. Once the dissolved oxygen in the water is unstable, it is likely to lead to coma or even death of Chinese sturgeon, which will affect the economic benefits. The water quality with great change of dissolved oxygen is not suitable as the water source for cultivating fry.
4. Lighting equipment
The light demand of Chinese sturgeon will change with different lifestyles. When the Chinese sturgeon enters the bottom, the light will generally not affect the growth and development of the Chinese sturgeon, but the high temperature in summer and direct sunlight will affect the growth of the Chinese sturgeon, so it is necessary to build a sunshade during artificial propagation.
2. Is Chinese sturgeon a freshwater fish or a marine fish?
1. Acipenser sinensis is a freshwater fish, but it also lives in seawater. In general, Chinese sturgeon will be produced in fresh water, but they have migratory habits, so when the young fish grow to about 15 cm after giving birth, they will live with them in the open sea, so they will be born in the upper reaches of rivers and grow in the sea for generations.
2. Acipenser sinensis is the largest and longest-lived freshwater fish, living in rivers and offshore waters. It is a kind of bottom fish with migratory or semi-migratory characteristics, mainly distributed below Jinsha River, the main stream of the Yangtze River in China, and other water systems such as Ganjiang River, Xiangjiang River, Minjiang River, Qiantang River and Pearl River occasionally appear.
