How to cultivate grass carp in typhoon weather

The 16th typhoon has hit this year and has been hovering in Guangdong, while Hu friends in Guangdong are not ready to prevent the typhoon, resulting in a large number of deaths and heavy losses of grass carp in fish ponds, coupled with the fact that there are more and more fish. Grass carp market this year is not very optimistic, so the loss is very serious, so this incident has attracted the attention of the majority of aquaculture farmers Today, the pro-agricultural network brings you how to raise grass carp in the weather of typhoon. I hope it can be helpful to you.

1. Water level management

The arrival of the typhoon also means the arrival of the storm, then it will have a great impact on the water level of the pond. For a while, the water level of the pond rises rapidly, so we should pay attention to the trend of the typhoon and deal with it in time. Lowering the water level of the pond before the typhoon comes, so that the loss can be reduced to a certain extent, and at the same time, when the rainstorm comes, the fish in the pond will not only take advantage of the potential to escape. In this way, as soon as the rainstorm stops, we can get the water level back to normal.

2. Pond management

As grass carp culture in the pond is still a relatively common culture mode, and the dam in the pond is actually not so strong after years of appearance, so when the typhoon comes, the pond dam will collapse, so the grass carp will escape. At the same time, the typhoon is relatively strong, and the damage to the body of grass carp is greater, so we should strengthen the river dam in time and set up a fence around it.

3. Change the water in time

The torrential rain caused by the typhoon itself may not be a problem, but when it falls into the pond and mixes with the previously farmed water, grass carp can not adapt to each other, and the oxygen in the water will be reduced accordingly. This has a great impact on the survival of grass carp. We can change the water in the pond in time after the typhoon, but the local water resources are basically affected by the typhoon. Therefore, before changing the water, we need to fully disinfect the water, then prevent it from being injected into the pool two days later, and add an appropriate amount of oxygenator to the water, which can also reduce the harm caused by the typhoon to a certain extent.

4. Feeding and management

Feeding management we can start from the daily feeding, do not have to wait until there is a typhoon to start preparation, otherwise everything will be too late. In the usual feeding process, we can feed an appropriate amount of bait that can enhance the physique of grass carp that is not harmful to grass carp, because grass carp is mainly based on edible forage, so we can mix an appropriate amount of bait in the fodder. in this way, the resistance of grass carp is also enhanced over time, so that it is not so easy to be hurt in case of typhoon, and can reduce certain losses.

5. Disease control

Disease prevention and control is generally the work after the typhoon, and it is also very important, because no matter how much preparation has been made before, the typhoon still does some harm to the grass carp itself. We need to salvage the grass carp in the pond, and then carefully observe whether they are injured or infected by the virus. If so, we should separate the injured grass carp from the diseased grass carp and soak them with oxytetracycline. This can play a link of injury and germicidal effect, and bait every day, so that you can almost recover in about a week.
