High-yield culture techniques of sea bass

The meat of sea bass is very delicious and nutritious, which is very popular with consumers in the market, and it is also one of the common important economic fishes. Because it can grow in sea water and fresh water, the area of artificial culture is constantly expanding. Below the pro-agricultural network to bring you the high-yield culture technology of sea bass, let's take a look.

1. Culture preparation

First of all, we should be prepared before breeding, choose a large pond with an area of 6-10 mu, which is too large and difficult to manage, and too little water body is unstable. This area is the most suitable. The water depth should be more than 2 meters, which requires adequate water source, clean water quality, no pollution and convenient transportation. Disinfect the pond before releasing seedlings, first empty the pond water, expose the bottom of the pond, use bleach or lime powder for disinfection and sterilization to keep the water deep to about 20 centimeters, soak and pour wine, and 1 meter of water can be released after a week.

2. Temporary rearing and stocking of fish fry

The history of sea bass culture is relatively short, the culture technology is not fully mature, and there is no large-scale fish fry cultivation base. The fry mainly comes from sea fishing, which is caught in spring. There will be losses on the way to fishing and transportation, reducing the survival rate, so it is necessary to carry out temporary culture during this period. Temporary culture is more convenient for cage culture. Generally, 3000 fish fry are temporarily raised per cubic meter of water, which can make the size of fish fry and reduce the density. During temporary culture, Artemia larvae or freshwater technical horns are fed in the first 7-10 days, and then fresh surimi are fed. When the fry grow to 8-10 cm, they can be cultured in the pond.

3. Input and feeding management

The sea bass is mainly fed by low-breeding miscellaneous fish, and in artificial culture, the bait is mainly low-breeding miscellaneous fish, supplemented by artificial ingredients. When the sea bass is in culture, its food grabbing speed is fast and the food consumption is large, so each feeding performance is fixed and quantitative, it is necessary to carefully observe whether the sea bass is full or not, so as to avoid wasting bait. Pay attention to the method when feeding, first feed a small amount of bait to attract the perch to come to grab food, then all the bait will be fed, and then stop feeding when they sink and not grab food. The frequency of feeding varies according to the temperature and season. During the peak growing season of sea bass in spring and summer every year, it is necessary to increase the feeding times, usually 4-5 times a day, while in early spring and late autumn, the temperature is low and is not suitable for perch growth. you need to reduce the number of feeding times.

4. Other management

In addition to feeding, inspections should be carried out several times a day to observe the problems in the culture pond and find that anomalies should be dealt with in a timely manner, including water quality, perch activity, escape prevention and disease prevention. Water quality management mainly observes the color, smell and transparency of the water, and finds that problems should be dealt with in time; while the activity of perch is to observe whether the perch is active, if it is not active enough and looks lifeless, it is necessary to find the reason and deal with it; to prevent escape, we should pay attention to the periphery of the pond to see if there is a perch escape phenomenon. The prevention and control of diseases is particularly important, usually to strengthen management, the discovery of diseases should be timely.

The above is the high-yield culture technology of sea bass brought by the pro-agricultural network, so much for the content of sea bass culture. If you want to know more, please pay attention to the pro-agricultural network.
