Culture model of tilapia

Tilapia is a kind of fish that we often eat in our life, and the culture area in our country is very large. The taste of tilapia is also very delicious, no matter what kind of cooking, can retain its fresh taste. And tilapia is rich in protein and various vitamins, so now the culture area of tilapia is getting larger and larger. So what are the culture models of tilapia? Let's take a look at it.

1. Pond culture

Pond culture is the most common culture mode of tilapia. People should choose places that are leeward to the sun, adequate water sources, quiet and pollution-free. Control the area of the pond according to the breeding quantity, thoroughly disinfect the pond, put it into the silt, then apply enough farm manure, and then be equipped with various breeding equipment such as aerator. When the spring temperature is stable at about 15 degrees, you can begin to release seedlings, the general number of tilapia should be controlled at about 2000, and then mixed with a small amount of silver carp and so on. Then it is necessary to do a good job in feeding and management, observe the growth of fish, and do a good job in changing water, preventing diseases, increasing oxygen and so on.

2. Rice field culture

Rice field farming is also a common farming mode in rural areas. First of all, select the rice field, and then after the completion of the rice field work, the fish fry should also be fully disinfected half a month before stocking, and fertile water should be cultivated a week ago to promote the growth of natural bait. Then, about a week after rice transplanting, fish fry can be released. Fish fry should be strong, energetic, wound-free and have little difference in size. The number of fish fry should be controlled according to the environment of the rice field, and the fish fry should be disinfected before stocking. After stocking to do a good job of management, in general, basically do not need to put bait, usually in the rice harvest can be raised.

3. Cage culture

Cage culture is a new mode of fish culture in recent years. when tilapia is cultured in cage, it can be raised alone or mixed. Different from pond and rice field culture, fish species cultured in cage culture should maintain a larger size, because the growth space of tilapia cultured in cage culture is relatively small. Therefore, the specification of fish species should be kept at about 30g, and then ensure that there is sufficient dissolved oxygen, because tilapia cannot float its head if it is cultured in cages. The last thing to control is the culture density, not too dense, otherwise it will affect the survival rate of tilapia.

4. Aquaculture

Running water culture is also one of the main modes of factory culture of tilapia. Aquaculture ponds can not be too large, generally controlled at about 40 square meters, and the oxygen content in the water should be consistent with cage culture as far as possible. Different from other aquaculture models, the choice of bait is very important, mainly based on full-price bait. The content of protein in the diet should not be less than 3pm 10. Then feed at least five times a day, depending on the weight of the tilapia. It should not be too much, and the residual bait should be fished out in time to avoid deterioration affecting the growth of tilapia.

The above is the tilapia culture model, I hope I can help you!
