How to raise tilapia

Tilapia can be regarded as a relatively fragile fish among the farmed fish, which is not resistant to high temperature and low temperature. Lower than 18 ℃ or higher than 40 ℃, the former is easy to fall into hibernation, and the latter is easy to die. Today, the pro-agricultural network asked you to pay attention to some things about tilapia culture.

1. Pond preparation

In order to provide a good growing environment for tilapia, the pond must be disinfected and repaired before culture. Who will be clean for the first time, clean the mud and then rinse it with water. Then the upper wall of the pool will be repaired more smoothly to avoid accidental injury to tilapia later. Secondly, to introduce lime water, be sure to sprinkle it all around. After cleaning the lime water, be sure to rinse thoroughly and dry for 7-10 days to ensure the disinfection effect. Then put in the pond water to precipitate for a period of time and slowly release the fish fry.

2. Fish fry release

In the early stage, as the fry is relatively fragile, we must pay attention to the water is not too deep, about one meter is good, this is conducive to fry breathing. Can be disinfected with salt water before release, the proportion is 3%, there is no time for about 30 minutes. Generally, the fry will be released around March, when the temperature just returned to 18 ℃, which is the most suitable for the survival of tilapia fry. In order to improve the survival rate, some high-protein fish meal can be put in early stage to improve nutrition. If there are 4000 fish fry per mu, if it is more than three centimeters, you should appropriately reduce the number of farmed fish.

3. Feeding and management

Tilapia is a highly omnivorous fish species, it will generally take the initiative to swallow organic detritus and some aquatic plants and so on, so the feed can be based on forage. In order to ensure the fluidity of the pond water and the richness of aquatic microorganisms, some aquatic plants can be planted at the edge and organic fertilizers can be put in. The feeding time is usually 8-9 am and 5-6 pm, which can be adjusted according to the change of seasonal climate. The temperature is generally high at noon, tilapia will choose a place to stay in the summer.

4. Points for attention

The feeding point should be fixed to facilitate tilapia to find food, each time is about half an hour, to ensure the efficiency of eating. The water depth of the pond is generally controlled at three meters. In the later stage, if tilapia is often found to breathe in bulk, then it is necessary to prepare aeration equipment. The growth cycle of tilapia is about 4 months, and if it is longer, the investment is not proportional to the income.

The above are some problems that need to be paid attention to when tilapia culture, because of the fragility of tilapia, we must invest 12 points of energy to manage, the return of this culture will basically make everyone satisfied.
