Artificial Culture methods of Pseudosciaena Crocea

Yellow croaker is a relatively rare species, the source of yellow croaker on the market mainly depends on fishermen in coastal areas to fish, but now slowly appeared the artificial culture of yellow croaker, of which the most common is pond culture and cage culture. Let's introduce the artificial culture methods of yellow croaker.

I. Culture preparation

As the yellow croaker is more difficult to raise, it is necessary to make adequate preparations before culture. if it is to be cultured in a cage, it is necessary to arrange the cage according to the specifications of the yellow croaker, usually the water depth in the cage is about four meters. the second is to avoid scraping of yellow croaker, it is best to choose a relatively soft cage for culture, if it is to use pond culture. Then you need to choose a place close to the water source, and you need to disinfect the pond and keep the water depth at about two meters. finally, you need to prepare oxygen supply equipment and equipment to regulate the water quality, and then you can formally breed it after everything is ready.

II. Fish species selection

Yellow croaker is more precious, so we must be very careful when choosing fish species, which can improve the survival rate of yellow croaker culture and reduce the loss. we usually choose fish species with uniform size, robust and lively, complete scales, shiny skin, no internal trauma and no disease, so that the fish school is conducive to unified management.

III. Fish fingerling restocking

We need to disinfect the fish before releasing the fish, because the purchased fish may carry some harmful substances such as parasites and bacteria, which will not only pollute the water but also affect the growth of the fish. Usually we put the fish in formalin for about half an hour, then fish it out and put it in clean water for about a day, and finally put the fish in cages or ponds for breeding.

IV. Feeding and management

Yellow croaker mainly feeds on frozen chub mackerel and ginseng. When raising it, we need to thaw the feed first, then make it into minced meat, and then feed it in a fixed place with some special fish feed on shift. At the same time, we can also feed some small fish, shrimp and scallop meat in an appropriate amount, so that the yellow croaker can have balanced nutrition in the process of growth and will not be malnourished. The newly released yellow croaker is usually tailed about twice a day, that is, it is fed in the morning and evening, and the feed consumption can be slowly increased when it is older.

V. Daily management

The daily management of yellow croaker is relatively important, it has high requirements for water quality. If pond culture is used, water must be changed every day and the pond must be cleaned irregularly for disinfection and sterilization. Cage culture only needs to remove the remaining food residue after each feeding, and then irregularly clean up the dirt and dirt on the cage and carry out disinfection and sterilization, the second is to pay attention to the water depth. Cage culture needs to set up a red tide warning in the farm, so that the depth of the cage can be adjusted in time, and the pond culture has to change the water every day, so it is good to keep it at a depth of two meters after each change of water, and finally it is the prevention and control of diseases and insect pests. You can mix some resistance-enhancing agents in the feed, and it is found that the diseased fish should be fished out in time for isolation treatment and disease prevention.

The above is the introduction of the artificial culture method of yellow croaker by Tuliu. the content of protein in yellow croaker is very high, and now the demand of yellow croaker is increasing day by day in the market. after vigorous fishing, the number of wild yellow croaker is also decreasing every year, so there are great prospects for the cultivation of yellow croaker.
