How to cope with typhoon weather in grass carp farming

This year's 16th typhoon has already struck and has been lingering over the Guangdong region, and friends in Guangdong had not made preparations to prevent the typhoon, which led to a large number of grass carp dying in the ponds and heavy losses. In addition, with more and more fish now available, the market for grass carp this year is not very optimistic, so the losses are very serious. After this incident, it has drawn great attention from the vast number of aquaculture farmers. Today, Qinong Net brings you how to farm grass carp when typhoon weather comes, hoping it can be of some help to everyone.

1. Water level management

The arrival of a typhoon means the arrival of storms, which will have a great impact on the pond water level. In a short time, the pond water level rises rapidly, so we must pay attention to the movement of the typhoon and deal with it in time. Before the typhoon arrives, lower the pond water level, which can reduce losses to a certain extent. At the same time, when the rainstorm comes, the fish in the pond will not take the opportunity to escape. In this way, once the rainstorm stops, we can restore the water level to its normal state.

2. Pond management

Because pond farming of grass carp is still a relatively common farming model at present, and the pond embankments are actually not so solid after many years, when a typhoon comes, the pond embankments will collapse, and the grass carp will escape. At the same time, the typhoon is relatively strong and causes relatively great harm to the bodies of grass carp, so we must reinforce the river embankments in time and set up surrounding fences.

3. Change the water in time

The rainstorm brought by the typhoon itself may not be a problem, but after it falls into the pond, it mixes with the previously farmed water. For a time, the grass carp school cannot adapt, and the oxygen in the water will also decrease accordingly, which has a great impact on the survival of grass carp. After the typhoon passes, we can promptly replace the water in the pond. However, the local water resources have basically all been affected by the typhoon, so before changing the water we need to first fully disinfect the water, then let it stand for two days before injecting it into the pond, and add an appropriate amount of oxygen-increasing agent to the water. This can also reduce the harm caused by the typhoon to a certain extent.

4. Feeding management

For feeding management, we can start developing it from daily feeding. We do not necessarily have to wait until a typhoon comes to start preparing, otherwise by then everything will already be too late. In our usual feeding process, we can appropriately feed some medicated bait that is not harmful to grass carp and can enhance their physique. Because grass carp mainly eat grass feed, we can mix an appropriate amount of medicated bait into the grass feed. Over time, the resistance of grass carp will also be enhanced, so when encountering a typhoon they will not be so easily harmed, and certain losses can be reduced.

5. Disease prevention and control

Disease prevention and control is generally the work after a typhoon, and it is also very important, because no matter how much preparation was made before, the typhoon still causes certain harm to the grass carp themselves. We need to retrieve the grass carp from the pond and then carefully observe whether they are injured or infected by viruses. If so, we must separate the injured and diseased grass carp, then soak them with oxytetracycline, which can play a role in alleviating the harm and sterilizing. At the same time, administer medicated bait every day, and persist for about a week, and they should mostly be able to recover.
