CATDOLL : CATDOLL: I want to raise yellow croaker. What experience do you have in raising yellow croaker?

As a marine fish, yellow croaker was previously caught in the wild. However, as the catch increased, wild yellow croaker resources were destroyed, so people began to try to artificially breed yellow croaker. Artificial breeding of yellow croaker is very difficult, and the most important method is to use cage breeding. The purchased fish species must be carefully selected before entering the cage, and fish with uniform size, strong and lively, and complete scales must be selected. In addition, they must be disinfected to avoid carrying germs and parasites. So today let us take a look at what experience we have in breeding yellow croaker if we want to breed it?

1. Culture Preparation

Since yellow croaker is difficult to raise, sufficient preparations need to be made before breeding. If cage breeding is adopted, the cage should be arranged according to the specifications of yellow croaker. Usually, the water depth in the cage is about four meters. Secondly, in order to avoid abrasions on yellow croaker, it is best to use cages with softer materials for breeding. If pond breeding is adopted, it is necessary to choose a place close to the water source and disinfect the pond. The water god can be kept at about two meters. Finally, oxygen supply equipment and water quality regulating equipment need to be prepared. After everything is prepared, breeding can be officially started.

2. Breeding pond

The average water depth of the pond should be more than 3m, and the deeper the better. The water change conditions should be good, and water should be changed for more than 12 days out of the 15 days of each tide. The pond size should be about 15 mu. The pond should be strictly desilted and disinfected before stocking fish. In order to prevent the water level from dropping due to pond leakage, or the water quality from deteriorating due to the inability to change water during the flood season, pumping equipment of corresponding size and power should be equipped. The breeding pond should preferably be located in a place with fresh water source to adjust the water quality.

3. Environmental management

The environment around the wintering site should be kept quiet to avoid noise interference. Do not stir the pool water at will, and be careful when checking and operating to prevent the wintering fish from being frightened and running around, wasting energy, increasing oxygen consumption, scratching the skin, and contracting diseases. Due to the heating and insulation effect of the plastic greenhouse, although the temperature outside the greenhouse is sometimes very low, the water temperature in the greenhouse is basically above 10℃ throughout the wintering period, and can reach 20℃ at the highest. The yellow croaker eats normally and grows slightly during the wintering period.

These experiences are that you need to know the growth cycle and reproduction cycle of yellow croaker, create a better breeding environment, have better water quality, and have better breeding methods.

You must pay attention to the water temperature for breeding, the surrounding temperature, the spaciousness of the space, the clarity and cleanliness of the water source, the climate, and daily light.

To choose suitable varieties for breeding, you must pay attention to the water conditions, cleanliness and hygiene, oxygen content, disinfection, and the feed ratio is also very important.

Before breeding, you must make adequate preparations. The cages should be arranged according to the specifications of yellow croaker. The water depth should be about 4 meters. The ponds should be disinfected regularly and kept close to the water source.
