Is it okay to raise fish in rainwater, can you raise fish directly in rainwater

Want to use rainwater to raise fish? Still don't think about it.

Theoretically, yes!!

However, due to environmental pollution and other problems, it is not suitable for direct fish farming with water.

The quality of the water body may improve slightly after being filtered and decontaminated by the natural ecosystem.

It depends on what kind of fish is raised, if it is a more delicate fish, it is not recommended to use rainwater, because now air pollution is becoming more and more serious, often acid rain, rain may cause some harm to some fish, it is recommended to use pH test paper to test the water quality before making a decision!

Rainwater cannot raise fish directly, because there are more impurities in the water, which will make the fish unable to breathe normally. You can choose the tap water that has been dried to raise fish. When raising fish, you need to choose a fish tank according to the size and number of fish, and you can feed it 2 or 3 times a day, and you need to change the water once a week.

If you raise tropical fish, you need to place a heating rod in the tank to control the water temperature above 20.

Rainwater should not be used to raise fish directly, because there are many impurities in the water, which will make the fish unable to live normally and are prone to death. Tap water can be selected when raising fish, because tap water contains a lot of chlorine, so it needs to be dried in advance before use, 2 days in spring and autumn, 1 day in summer, and 3 days in winter.

When raising fish, it is necessary to choose the right fish tank according to the size and number of fish, and then pay attention to the problem of feeding, you can feed 3 times a day, each feeding should not be too much, and you need to change the water once a week to ensure that the water quality is clean and hygienic.

If the feeding density is too large, it is necessary to install an oxygen pump in the tank to ensure that there is sufficient oxygen in the container, and if the tropical fish are raised, it is also necessary to place a heating rod in the tank to stabilize the water temperature above 20, so as to make the healthy growth of the fish.

1. Rainwater cannot raise fish.

2. If the rainwater is not clean, there will be problems with fish farming. It is best to use tap water. Due to the high permanganate index in the water, it is necessary to dry it to remove chlorine.

3. The acidity and alkalinity of rainwater. There are some areas with serious environmental pollution that have been harmed by acid rain. In other words, the pH of rainwater is seriously out of the norm.

The pH of rainwater can be tested with pH paper, and once it exceeds the norm, it cannot be used to raise fingerlings.

4. Because the water in the fish tank is hot, it causes heat convection in the glass tank. The waste and impurities under the glass tank will be stirred up by the running water, and then the fish will suffer from a temporary lack of oxygen, and in severe cases, they will die immediately.

The degree of pollution of rainwater.

Rain** in the clouds. Water under the action of high temperatures forms water vapor, which can condense into small droplets on objects with lower temperatures. If you collect it all at this point, you get distilled water, which is a very clean water resource.

If you don't collect the water vapor, they will float away and form clouds hundreds of meters in the air. When the clouds reach a certain weight, they will pour down, forming rain. I don't know if you feel this way, every time you go out for a walk after the rain, you will feel that the air is exceptionally fresh.

That's the rain to work with. When the rain falls, it will carry some dust and float it in the air, so the rain that falls contains a lot of impurities and dirt.

But does this prove that rainwater cannot be used to raise fish? No. Almost one-third of the days of the year rain.

Ponds and rivers in the wild are filled with rainwater little by little. Fish in the wild are still alive and well. This is not a problem with the fish's own physique, but it actually proves that rainwater can be used to raise fish, and there is no problem.

You may say, "Rainwater has a lot of nitrogen and can't be used to raise fish." "It's actually true that rainwater contains nitrogen.

Nitrogen is a highly volatile substance that dissolves into rain on rainy days. But if you use it to raise fish, it won't be long before the substance will evaporate again, so you don't have to worry about what problems it will cause to the fish.

If you want to use rainwater to raise fish, you still have to go through a series of treatments before you can use it to raise fish. So what should be done?

How to purify the rainwater so that it can be used for fish farming?

The rain in the wild is also very dirty and contains a lot of impurities. But the environment in the wild is very different from the environment in which we raise fish at home. There is land in the wild.

Rainwater falling down is a bit like the principle of swamp filtration, rainwater will penetrate the soil, and then flow into the water, impurities and everything basically stay in the soil. But what if you don't have swamp filtration at home? It's as simple as finding a larger container to fill all the rainwater with no lid and leaving it in a cool place to settle naturally.

After about a day or two, these impurities will basically settle down and will all stay at the bottom of the container. When you need rainwater, just take the top half of the water. If you are not at ease, you can put a physical filter, which is also very effective.

Nitrogen is also slowly and completely volatilized during precipitation.

Someone has to ask: what is the use of rainwater? This may only be known to those who live in the city.

Most of the water in the countryside comes from wells, which are free of chlorine or chemicals. However, the city uses tap water, and the tap water contains chlorine, so it cannot be used directly to raise fish, and it is very convenient to use rainwater directly.

As long as you don't use tap water to raise fish, rainwater is of little use. However, if you use tap water to raise fish, it is necessary to collect some rainwater, which can be used in case of emergency.

Yes, but because domestic ornamental fish are different from those in wild ponds, it takes a few days of impurities to precipitate and pollutants to be removed from rainwater.

Rainwater should not be used to raise ornamental fish, and it will not be better than tap water, because rainwater has a lot of unfiltered pollutants and impurities that are not good for fish.

Want to use rainwater to raise fish? Still don't think about it.

Rainwater can not raise fish. Because rainwater is generally weakly acidic or polluted, try not to use rainwater to raise fish. Fish farming has strict requirements for water quality, and it is necessary to change the water frequently to keep the water clean.

Weakly acidic rain can induce various diseases in fish. Among them, the most direct harms are as follows:

1. The ** of the fish ulcerates for unknown reasons.

2. Unknown symptoms occur in the eyes, nose and respiratory tract of the fish.

3. The number of fungal infections in fish schools increased.

4. Increase in malformed eggs.

5. Unexplained loss of appetite and stunted growth of fish.

6. Fish spawning declines, and the insemination rate decreases.

Rainwater can raise fish, but pay attention to its acid residue bend alkaline, you can use pH test paper to measure the value, neutral rainwater can raise fish, but rainwater is generally weakly acidic or polluted, try not to use rainwater to raise fish. Fish farming does not have strict requirements for water quality, and there is no need to change the water every day, but the water quality must be kept clean. Weakly acidic rain can induce various diseases in fish.

Fish farming method: 1. The filtration system is very simple, the submersible filter (the very ordinary kind, sold everywhere), filter cotton, biochemical cotton, activated carbon (I bought it is scattered, and the market weighed a few catties of activated carbon sand bags made by myself), filter cotton is prevented on the activated carbon package, and the biochemical cotton is under the activated carbon package, so that the activated carbon is used for a long time, and I think the effect is also the best. I never buy biochemical balls, nitrifying bacteria.

2. I don't think it's necessary to use cool boiled water for changing the water, if I use it, I have 5 big gangs (3 1m) and 2 small tanks, change the water, just boiling the water for half a day and not be tired to death.

3. The water temperature is generally kept at about 27-28 degrees, according to my experience, the appetite of the fish at this temperature is good, and the body is good. The water temperature is generally not as good as the stuffiness to exceed 28 degrees, and I think everyone knows about it. I want to buy a better heating rod, I use all domestic products, two of them are 13 yuan and have been used for 3 years, and the heating is very accurate.

This thing is not very high-tech, so you don't have to buy imported ones. If you have a lot of money, that's a different story.

4. On the issue of oxygen supply, I do not advocate that the more oxygen, the better, as long as you pay attention to the stocking density, keep the oxygen in the water sufficient, I only have half a day of oxygen during the day, and do not take oxygen or feed at night The amount of oxygen is very low, because the oxygen consumption of the fish activity at night is also low, which is also good for aquatic plants, and gives the fish a quiet rest environment. If the air pump rings from morning to night, the fish farmers can't stand it, let alone the fish. The above is based on the premise of controlling the stocking density (the oxygen should be given to the fish during the treatment period), pay attention to the fish in the high oxygen environment for a long time, do not raise the strong man who survives with medium and low oxygen to a high oxygen lady.

5. I use the light of the indoor astigmatism and the light of the fish tank, pay attention not to let the sunlight shine directly, the sunlight is easier to raise green moss than the light. I shine 3-4 hours a day, purple light has a sterilization effect, but if you use it for half an hour - an hour even people can't stand it, how can the fish suffer it, the purple light has a good precipitation effect on the pigment, but it also has a great harmful effect on the fish, I am not very advocated, if the length of time I am not clear.

6. The pH of water is not very important, so there is no need to take test strips to measure it. The water that people can drink normally is basically suitable for fish farming, except in special areas or in the case of reproduction.

Rainwater cannot be used to raise fish directly. The rain is not clean, and fish farming can be problematic, so it is better to use tap water. Tap water needs to be dried before raising fish, because the water contains residual chlorine, so it needs to be removed by some methods.

If chlorine is removed by drying, the drying time is different in different seasons, one day is enough in summer, it may take two days in spring and autumn, and about three days in winter. In addition, if the water consumption is large, it is recommended to use chlorine remover to trap the water, but the amount should be controlled.
