How to raise crucian carp so they don't die? Farming methods to improve the survival rate
Crucian carp is a relatively common farmed aquatic product, and death during farming is a serious problem. Many farmers report that the mortality rate of farmed crucian carp is very high. In fact, crucian carp is very easy to keep alive. If the mortality rate is high, then you must check whether you have done these aspects well.
1. Do a good job of water quality management
Water quality is a key point in farming crucian carp. Good water quality does not just mean being pollution-free; the water quality crucian carp needs, besides being pollution-free, also involves the content of various elements. Calcium and phosphorus are elements to pay extra attention to when farming crucian carp. If the content of these two elements in the water is relatively low, then the crucian carp will not be raised well. When managing water quality, you should also pay attention to the issue of fertilizing the water. Abundant plankton is what crucian carp like, and this will give them more food sources. You can also observe the water quality through the fertilization condition of the water. If the water quality is poor, it is best not to raise fish!
2. Control the farming density
Density is also one of the common problems in fish farming. Crucian carp generally does not grow very large, so its density is generally set from the time the fry are stocked, but the high mortality rate is also closely related to excessive density. Crucian carp is active and needs a relatively large activity space. They will swim around in this space looking for food, and high density means that competition among crucian carp will increase. Although crucian carp is not prone to fighting, when the density is too high, the fish with poorer growth are more likely to starve to death, because they cannot outcompete the other crucian carp for feed, ultimately forming a vicious cycle. Moreover, high density also easily leads to insufficient oxygen, seriously threatening the survival of the crucian carp in the entire pond.
3. Adjust feeding at any time
Raising crucian carp is somewhat different from raising other fish. Crucian carp itself is active, eats little but digests quickly, so feeding pursues small amounts and many times, with relatively frequent feeding every day. When crucian carp eats, it is relatively fierce and basically accepts everything; as long as it can swallow it, it will eat it. Therefore, the feed being fed must be slowly adjusted according to its size, otherwise it is easy to overfeed the crucian carp to death. When the temperature is high, crucian carp eats quickly and a lot; when the temperature is low, it eats slowly and little. Everyone should adjust the feeding for different temperature ranges according to this. Normally, the number of feedings per day is around 5-6 times.
4. Improve the pond environment
The quality of the pond environment will also affect the death situation of crucian carp, so this also needs to be improved. Under the pond farming model, the aquatic cycle is not very fast, but the production of various pathogens or waste in the fish pond is relatively large. Daily feed, crucian carp excrement, pathogens naturally breeding in the water, and so on are all common causes leading to the death of crucian carp. When improving the environment, mainly target pond clearing, sterilization, and similar situations and proceed slowly, as this can effectively reduce their mortality rate.
The above are some methods to prevent crucian carp from dying during farming. If everyone finds that their mortality rate is relatively high, then you can pay more attention to the above issues to protect the growth of crucian carp.
