It usually takes at least 3 years for sturgeon to grow to 10 kg. Sturgeon is a benthic fish, which generally lives in rivers and offshore waters. Big body, fierce temperament. It usually preys on small and slow-moving benthos and stops eating during spawning. At present, seven species of wild sturgeon have been found in China, namely, ACIPENSER sinensis, ACIPENSER schrenckii, ACIPENSER schrenckii, ACIPENSER nudibranchi, ACIPENSER Siberia and ACIPENSER kuiper. Among them, ACIPENSER sinensis and ACIPENSER schrenckii are mainly distributed in the Yangtze River and Jinsha River basins.

How many years do you keep a catty or a catty of sturgeon?

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.

1. In general, sturgeons need to be cultured for at least 3 years or even longer when they grow to 10 kg.

2. Sturgeon is big and fierce. Small, slow-moving benthic animals are usually the main food, and they stop eating when laying eggs.

3. Acipenser sinensis belongs to the bottom fish, generally living in rivers and offshore waters, with a long life span, and some Acipenser sinensis can live to about 40 years old.

4. At present, seven species of wild sturgeon have been found in China, namely, ACIPENSER sinensis, ACIPENSER schrenckii, ACIPENSER Dan, ACIPENSER nudus, ACIPENSER Siberia and ACIPENSER Sakhalin, among which ACIPENSER sinensis and ACIPENSER Dan are mainly distributed in the Yangtze River and Jinsha River basins.

5. In the larval stage, the staple food of sturgeon is mostly plankton; In the juvenile stage, the staple food is benthic aquatic oligochaeta, aquatic insects, small fish and shrimp and molluscs; In the adult stage, the staple food is benthos and animal and plant residues.

Second, the culture conditions of sturgeon

1, water temperature condition

Water temperature will affect the growth of sturgeon, especially during the production and incubation period. In general, the suitable water temperature for aquaculture is about 20℃.

2. Water quality conditions

The transparency of the pool water should be about 50 cm, and the PH value should be about 7.5. Sturgeon should not live in acidic water.

3. Lighting conditions

When sturgeon lives underwater, light will not affect its growth and development. After summer, the temperature is high, and direct sunlight will affect their lives. At this time, you can give them a parasol.

4, dissolved oxygen conditions

(1) The dissolved oxygen content in the pond water should be above 5 mg/L. If the dissolved oxygen is insufficient, the sturgeon is prone to coma or death.

(2) The water quality with great changes in dissolved oxygen should not be used as the water source for cultivating fry.
