How to raise crucian carp not to die

Crucian carp is a common kind of farmed aquatic products, and death is a serious problem when farmed. Many farmers respond that the mortality rate of farmed crucian carp is very high. In fact, crucian carp is very good to survive, if the mortality rate is high, then we must pay attention to whether they have done a good job in these aspects.

1. Do a good job in water quality management

Water quality is a key point of crucian carp culture, good water quality does not mean that there is no pollution, crucian carp demand for water quality in addition to non-pollution is the content of various elements. Calcium and phosphorus elements should be paid more attention to when breeding crucian carp, if the content of these two elements in the water is relatively small, then crucian carp can not be raised well. When managing water quality, we should also pay attention to the problem of fertilizer and water. Crucian carp like rich plankton, which will give them more food sources. We can also observe the water quality through the situation of fertilizer and water. If the water quality is not good, it is best not to raise fish!

2. Control the culture density.

Density is also one of the common problems in fish culture, crucian carp is generally not very large, so its density is generally determined from the beginning of seedling release, but there is also a lot of relationship between high mortality and high density. Crucian carp are active, need a relatively large place for activities, they will swim around in this place to find food, and high density means that the competition between crucian carp will become bigger, although crucian carp is not prone to fights, but some fish with higher density are easy to starve to death, because feed can not beat other crucian carp, and finally form a vicious circle. And the high density is also prone to lack of oxygen, which is a serious threat to the survival of crucian carp in the whole pond.

3. Adjust feeding at any time

Raising crucian carp and other fish will be different, crucian carp itself active, eat not much but digest quickly, so the pursuit of feeding is a small number of times, feeding more frequently every day. Crucian carp is more ferocious when eating, basically no refusals, as long as the belly will be eaten, feeding feed should be slowly adjusted with its size, so that it is easy to support crucian carp. Crucian carp eat fast and more when the temperature is high, while slow and less when the temperature is low. We should adjust the feeding of different temperature sections according to this. Normally, the feeding times are about 5-6 times a day.

4. Improve the pond environment

The pond environment will also affect the death of crucian carp, so this also needs to be improved. Under the mode of pond culture, the aquatic cycle will not be very fast, but there are many kinds of bacteria or garbage in fish ponds, such as daily feed, crucian carp excreta, naturally growing bacteria in water, and so on. these are some common causes of crucian carp death. When improving the environment, it is mainly aimed at clearing ponds, sterilization and other conditions slowly, which can effectively reduce its mortality.

These are some ways to prevent the death of crucian carp when farmed. If you find that the mortality rate is relatively high, then you can pay more attention to these problems to protect the growth of crucian carp.
