You can choose pond culture. The pool is required to be close to the water source to facilitate drainage and irrigation. You can change water every day. The pond area depends on the scale of farming. This pond should be 2-3 meters deep. The transparency of the pool water should be more than half a meter, the water temperature should be kept at 8-28 degrees, the dissolved oxygen should be kept above 5 ml per liter, and the pool water is slightly alkaline. Clean and disinfect the pond before stocking to eliminate harmful bacteria and microorganisms in the pond. First, pour 10-20cm of water into the pool and spray quicklime throughout the pool. Generally, each mu is sprayed with quicklime 100- 150kg, and discharged into the pond after one week. The release time is in late April or early May. When the water temperature is suitable for fry growth, attention should be paid to the requirements of varieties and specifications when throwing fry, which is beneficial to management. Too big difference in specifications will lead to the phenomenon of grasping food, which is not conducive to feeding management. Generally speaking, the fry size is per fish 100g, and the stocking density is controlled at about 500-700 fish per mu. It is best to go through a period of temporary culture before release to adapt to the new environment and avoid unnecessary losses.
Larval stage of Pseudosciaena crocea mainly feeds on zooplankton such as copepods, mysids and krill, while adult fish mainly feed on crustaceans such as fish or shrimps and crabs. In artificial culture, frozen pelagic fish are generally used as the main food, combined with other bait. Cut frozen fish into delicious fillets for eating, or grind them into minced meat, stir them into sticky bait, and then squeeze them into different sizes for eating. Other nutrients, such as vitamins, can also be added when mixing minced meat. Large yellow croaker is fed once every morning and evening, which is characterized by slow feeding and small quantity. The amount of food eaten depends on the water temperature, the weather and the amount of fish eaten. Many consumers say that wild yellow croaker is really expensive, and a few or two large yellow croaker can sell for hundreds of dollars. As we all know, wild yellow croaker is almost extinct. It has fresh and tender meat, rich nutrition, high medicinal value and full of treasures. Moreover, wild yellow croaker is more nutritious and tastes better than cultured yellow croaker, and its swim bladder can be dried in the sun to make valuable food "fish belly" and "yellow croaker glue". Things are vaguely expensive, so wild yellow croaker is still a hot commodity no matter how high the price is.
We can easily see that the value of yellow croaker is extremely high and the market price is not cheap. Yellow croaker is rich in nutrition, has a good dietotherapy effect on people with weak constitution, has a certain health care function, and is very suitable for the elderly. Yellow croaker is one of the most important economic seafood in China and is deeply loved by consumers. It is a famous high-end seafood, and its consumption demand is very strong. According to statistics, in the East China Sea, the fishing output of yellow croaker accounts for 12.6% of the main economic fish output. At present, wild yellow croaker has become very scarce after long-term overfishing and harsh environment, while artificial yellow croaker has not been cultivated on a large scale, so yellow croaker resources are still scarce, and the price naturally rises, which has broad breeding prospects.
