Tilapia prefer to grow in a warm environment, but the farmer that raises a large area, how to keep them warm in winter. Because tilapia is particularly vulnerable to death in winter. In the winter, the weather is cold, and the tilapia's constitution will decline, making it particularly vulnerable to illness. Zhengzhou Fusmar Machinery is a professional fish feed machine manufacturer, this article will introduce the tilapia growth environment in detail.
Water Temperature Control
The most important thing is to keep the water temperature in winter. Generally, breeders who farm tilapia can play a well at the pond. Everyone knows the water inside the well, the well water is very cool in the summer and it feels warm in the winter. So we can introduce the well water into the pond and keep the temperature of the fish pond. Farmers who have raised tilapia know that the deeper the water, the less the cold water will affect the temperature of the water. Therefore, in the winter, you can add more water to the pond and let them hide under the pond. A layer of quilts is the same. It recommended that the farmers keep the water temperature at the bottom of the pond at around 17℃ so that tilapia is not easy to die.
It also builds a windshield that blocks the cold current around the pond. When the windshield is built, the cold air outside the room can separate from the air inside the house, thus maintaining the temperature of the water. Other operation, that is, before the winter comes, you can build a shed around you. The shed covered with a layer of light-transmissive plastic film, ultraviolet light can dry into the pond to eliminate germs, and it can also raise the temperature of the pond.
Selection Of Fish Feed Pellets
The tilapia feed cannot be too single in winter. Before the winter, some nutrient-rich feeds were used for feeding, because after the winter, tilapia didn't eat much, just like hibernation. However, this is very bad for their body, so you can choose to feed when the sun shines into the water, let them eat a little more to save the energy and survive the winter. If anything possible, you can use a fish feed production line equipment to make fish feed pellets by yourself.
Breeding Density
In the winter, some fertilizer is thrown into the pond, so that the plankton in the water grows rapidly, and it can also provide a part of the food source for tilapia. However, there is a small drawback to doing this, which is that it is easy to have some parasites and bacteria in the pond. Therefore, at this time, the pond should be sterilized and pesticidal work to prevent some infections, resulting in a decline in the production of tilapia. Of course, a reasonable density is also necessary when breeding. In winter, most of the operations above will seal the fish pond. So it is good to sell some grown tilapia, otherwise, it will affect other fish growth.
