Artificial Culture methods of Pseudosciaena Crocea

Yellow croaker is a relatively rare species. In the past, yellow croaker was basically wild, and the source of yellow croaker on the market mainly depended on fishing by fishermen in coastal areas, but now artificial culture of yellow croaker has gradually emerged. and there are many ways of culture, of which the most common are pond culture and cage culture, so today let's learn the artificial culture method of yellow croaker.

1. Culture preparation

As the yellow croaker is more difficult to raise, so it is necessary to make adequate preparations before breeding. If it is to collect cage culture, then 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 the yellow croaker, it is best to choose a relatively soft cage for culture. If it is cultivated in a pond, it needs to be selected close to the water source, and the pond should be disinfected. The water god can be kept at about two meters. Finally, oxygen supply equipment and equipment for regulating water quality need to be prepared. After everything is ready, it can be officially farmed.

2. 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, strong and lively, complete scales, shiny skin, no internal trauma and no disease, so that the fish shoals can be managed in a unified way.

3. Fish restocking

We need to disinfect the fish before stocking, 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 them out and put them in clear water for a day or so, and finally put the fish in cages or ponds for breeding.

4. Feeding and management

Yellow croaker mainly takes frozen mackerel ginseng fish as food, when raising, we need to thaw the feed first, and then make it into minced meat, and then feed some special fish feed in a fixed place. At the same time, we can also feed some small fish, shrimp and scallop meat, so that the yellow croaker in the growth process has a balanced nutrition, there will not be malnutrition. 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.

5. Daily management

The daily management of yellow croaker is more 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 pond culture has to change water every day, so keep it at a depth of two meters after each change of water. Finally, the prevention and control of diseases and insect pests, can be mixed in the feed to enhance resistance agents, found that diseased fish should be fished out in time for isolation treatment, at the same time for disease prevention.
