How many years does a sturgeon generally need to be farmed before it can spawn?
Summary According to relevant research, female fish are around 16-29 years old when they spawn, and their body weight generally reaches around 170-300 kg, while male fish reach sexual maturity at around 9-22 years old, with a body weight of around 40-125 kg. The fish school stops feeding during the spawning period, and the optimal hatching water temperature for the eggs is around 20°C.

How should sturgeon stocking density be controlled to be reasonable?
Abstract The optimal stocking density for sturgeon is 2-4 kg/㎡, the optimal stocking density for Russian sturgeon can reach 4-5 kg/㎡, the Russian sturgeon has the fastest growth rate among sturgeons, and according to the growth condition of the fish, the stocking density should also be adjusted accordingly. At present, cage culture of sturgeon is the most worthwhile culture method to promote.

Are Sturgeons Easy to Keep? Understanding Sturgeon Farming Difficulty in One Article
Abstract Artificial sturgeon farming requires creating a suitable living environment, with a growth water temperature of 20-24°C, a pH value between 7.2-8, a transparency of 20-40cm, and a dissolved oxygen content of 6-8mg/L. Do a good job in the breeding and rearing of fry, and carry out domestication and feed conversion in good time. Provide high-quality protein feed and feed at fixed times, fixed spots and fixed amounts.

What conditions are needed for sturgeon farming? A must-read for farmers
Summary Water temperature can be controlled between 0-37°C, dissolved oxygen in the water should be above 5 mg/L, pH between 7-8, and there is no high requirement for salinity. Light intensity does not affect growth; in summer, set up a shade awning above the pond to prevent the water temperature from getting too high. The substrate for the growth of fry and juvenile sturgeon must be

What conditions are needed for sturgeon farming? A complete analysis of farming techniques
Sturgeon is the oldest fish in the world, and it is also the largest existing fish species in the world today. For this rather valuable fish species, many people have only heard of it, and few have actually seen it. However, with the development of people's understanding of the value of sturgeon, the market

Detailed Explanation of Key Points of Sturgeon Cage Culture Technology
Recently, sturgeon farming in South China has shown a trend of gradual recovery and warming, especially in Hainan Province, China, where a large number of shrimp farmers have switched to sturgeon farming. Sturgeon farming models are diverse, and here we introduce a rapid grow-out technology for sturgeon in cages. Using cages to farm sturgeon has many advantages

Cage Culture Methods and Technical Key Points for Sturgeon
The sturgeon series varieties have the characteristics of wide adaptability, fast growth, short culture cycle, good market prospects and high economic returns. Using cages to culture sturgeon is a very good intensive production method. Compared with pond culture of sturgeon, it has the following advantages: large water exchange volume

What points should be noted in sturgeon fry rearing?
With the vigorous rise of sturgeon aquaculture, the price of commercial sturgeon keeps falling, and the profit margin is getting smaller and smaller. Improving the survival rate of sturgeon fry and fingerlings is one of the main means of increasing profits in sturgeon aquaculture. Farming sturgeon in the south generally requires southward relocation and acclimation, which

Experience Sharing on Large-Scale Sturgeon Farming in Ponds
In November 2000, the author used 80 mu of ponds in Meizhou, Guangdong, to farm hybrid sturgeon (Siberian sturgeon × Kaluga sturgeon) with stream water. After 180 days of rearing, the average yield reached 831.25 kg per mu, achieving relatively good economic returns. The key points of the farming process in Pond No. 1 are summarized as follows:
