How is pisciculture often dead to return a responsibility, how does novice pisciculture just feed?

There are usually four reasons for the death of fish. The first is the problem of feeding, feeding too much to kill it. The second is the problem of changing water, changing water too frequently or too much water, stimulating the fish to die. The third reason is the density of farming, too many fish, the demand for oxygen will increase, but also may attack each other leading to death. The fourth is the reason why the tank is not opened well, and it is necessary to re-open the tank to raise water.

1. the feeding problem

Fish farming must feed the fish. Many people feed the fish because they are worried that the fish will not have enough to eat, so they will keep feeding. However, some fish will eat as long as they are fed. They have no idea at all about having enough to eat. It is easy to feed too much if they come and go. Often feeding too much can easily cause the fish to suffer from enteritis, or to die of overeating. In view of this situation, we need to know the amount of feed according to the size of the fish, and do not overfeed.

2. the problem of water change

Fish farming must change water, even if your filter material is good, nitrification system is perfect, no water change is not allowed. But the amount of water is also a problem, if too much, the stimulation of the fish body is greater, it will affect their appetite, and even lead to the death of fish. If the water is changed too little, the water body is still turbid, and the meaning of changing water is lost. Generally, a good filter tank can be changed every half month, while a bad one should be changed every week, and the amount of water changed each time is about a quarter.

3. the breeding density is high

The number of fish to be raised depends on the size of the tank. If the fish are blindly raised in groups and mixed, some fish with territorial consciousness will attack each other, causing a large number of fish to die. Moreover, more fish need more oxygen, and if the oxygen is not enough, the fish will suffocate to death. Therefore, fish farming needs to control the breeding density, which not only depends on the number of fish, but also refers to the size of fish. For example, 60 cm long tank, usually only 20 5 cm size of fish, more than enough.

4. the tank is not open well

Open the tank is the first step in fish farming, fish tanks to buy direct fish farming, the fish will certainly not live long. Generally, the fish tank should be disinfected first, then washed with clean water, poured into the trapped water, added a little nitrifying bacteria and fish food, after the establishment of a good nitrification system, the water quality will be mixed first and then clear, so that fish can be raised. However, it is best to use a few fish into the tank to test the water, no problem to put the fish to be raised.
