Can you use warm water for fish farming in winter, and can you heat water if the water temperature f

The warm water cools down quickly, and the key is to keep the water temperature relatively stable. To use a heating rod.

1. How much is the appropriate water temperature for fish farming in winter?

If you want to raise fish in winter, if it is a broad-temperature fish such as goldfish that is not very afraid of cold, it is enough to keep the water temperature above 4. If you are a tropical fish, keep the water temperature above 20, but it is best not to exceed 30. It should be noted that the temperature difference between day and night should not be too large, otherwise it will have adverse effects on the health of the fish and even make them sick.

2. Which fish are more hardy.

1. Goldfish: Goldfish is a more common ornamental fish, bred from crucian carp, usually divided into four strains, namely grass species, cultural species, dragon species and egg species, among which grass species of goldfish are the best to raise, grass gold is also one of the most widely farmed fish, relatively resistant to low temperatures, and has a strong ability to adapt to the environment.

2. Koi: Koi is a high-grade ornamental fish, which is itself bred from carp, so it has a wide range of temperature acceptance and can grow in an environment of 5-30. It should be noted that koi fish are much larger than goldfish, so they need a larger tank to keep them alive.

3. Medaka: There are many types of medaka, among which medaka is a very good ornamental species. This fish is very widely distributed in China, and it is found in many water systems, and the temperature requirements are not high. And because of its small size, it does not consume much oxygen.

It is possible to raise fish in warm water, but it must be tropical, and it should be noted that the water should not be boiled, because then there will be no oxygen in the water, and the fish will die easily.

The following is an introduction to the precautions for fish farming:

Fish farming starts with water. Clean water is available, rainwater, well water, tap water can be, and it is better to feed the water and be tender and green.

Change the water. If the food is less and the filtration is strong, it should be changed once every 20-30 days in summer, and in winter, the water should be considered when it is close to the old green, and the water volume should be controlled at one-third to one-quarter each time. Changqing filtration and less water change.

Feeding amount. To feed in moderation, fish are more hungry, if fed too much, it will lead to a large burden of filtration, and the water quality is also easy to spoil.

The water temperature of fish farming is too low to heat the water, because the oxygen in the hot water is graded due to the high temperature, and the oxygen content is relatively low, and it is easy to burn the upper fish.

The correct heating method is as follows: use two 300w heating rods, both of which are adjusted to 27-28 degrees, so that even if one is broken, there is another work, and the difference is not much lower than your room temperature will save electricity. If you don't have a heating rod, it's best to warm up hot and cold water before pouring it into the tank.

If the fish water is too cold in winter, you can use a heating rod to keep warm, especially if you are raising tropical fish, the temperature must be controlled between 20-30. At the same time, it is also necessary to pay attention to the water change, due to the low temperature, the water change should not be too frequent, otherwise it will cause the fish to have a stress response. Generally, the water should be changed every 15-20 days in winter, and the water change must be carried out at noon, when the climate is mild.

What are the downsides of the water being too cold.

1. Affect appetite: As an ectothermic animal, fish's own activities will be affected by temperature, and if the water temperature is relatively low, it will stop feeding. In order for it to regain its appetite, it needs to be warmed up properly.

However, the temperature should not be raised too high, and if the temperature difference is too large, it will also be detrimental to their health.

2. Slow growth: Fish living in cold water generally have a slow metabolism, so it is not easy to grow, and they can't raise it for a long time, and they will even raise it into an old fish. In order to ensure its healthy development, in addition to heating up, it is necessary to properly oxygenate and provide adequate food.

3. Restricted species: cold-water fish farming can only raise some wide-temperature fish, not tropical fish, so that the breeding species will be greatly limited. Usually only a few ornamental fish such as goldfish and koi fish can tolerate low temperatures, such as angelfish, arowana, monk fish, etc. are all tropical fish, which cannot be raised in cold water.

Summary. Winter also has the sun and ultraviolet rays.

You don't need to change the water in the fish tank too often in winter. If the water is easy to be turbid, the frequency of water change should be appropriately increased, if the water is relatively clear, the frequency of water change should be appropriately reduced, and the water temperature balance should not exceed one-third of the total water volume each time.

Dear, you can take a look here.

I'm a novice who hasn't raised fish yet, and they all say that fish farming comes first.

It is said that fish farming starts with water, and there is no sun in winter, and you can't bask in water, how to raise water.

Winter also has the sun and ultraviolet rays.

1.Wash the tank to eliminate orange potato poisoning. First of all, the newly purchased fish tank should be cleaned and disinfected.

2.Add water to remove chlorine. Add tap water to the cleaned fish tank, the tap water chain contains a large amount of chlorine, and it should be left for a few days to allow the chlorine in the water to volatilize and excite.

3.Nitrification of water.

Is it okay to fill the fish tank with water and put it outside in the sun?

Is it okay to leave it in the house for a few days without sun exposure?

Is it okay to leave it in the house for a few days without sun exposure?

OK. Put the fish tank full of water, add nitrifying bacteria, open the filter, and raise it for a week.

After a week, you can put the fish in the tank for a few days, right? Right,

In winter, Wen Songdan water can be appropriately added to the fish tank, but the temperature difference between the temperature of the new water and the old water should not exceed 3, otherwise the fish may be uncomfortable.

Although you can use warm water to farm fish in winter, do not use boiling water. Although the boiled water does not have chlorine, it has relatively little oxygen, which is not suitable for fish to survive.

When changing the water, you can raise the temperature to between 20-30 according to the habits of the fish, and then dry it until the water temperature is consistent with the old water, and then change it.

When changing the water for fish in winter, you need to pay attention to the frequency and amount of water change. In winter, when the temperature is low, the speed of fish metabolism will also be reduced, and the pollution of water quality will also be reduced, so the water can be changed once every 2-4 weeks, and the amount of each water change is controlled at a quarter of the total water volume. However, the specific frequency of water change is best determined according to the water quality, and if the water quality is poor, the frequency of water change needs to be increased.

When changing the water, you need to control the water flow, and try not to let the current hit the fish to avoid their stress reaction.

In winter, fish need to be fed, although the appetite of the fish will be affected after winter, but they also need to eat normally to ensure that their nutrition is sufficient.

The keeper can decide the amount of feed according to the water temperature in the tank and the habits of the fish, if the keeper can ensure that the temperature is stable, then the normal feeding amount can be fed.

If the temperature in the tank is low, then the amount of food needs to be reduced by half to avoid indigestion.

When raising fish in winter, it is also necessary to pay attention to the amount and frequency of water changes. Because the temperature is low in winter, the keeper needs to pay attention to the temperature difference between the new water and the old water when changing the water, and try not to exceed 2-3 to avoid discomfort for the fish. Also pay attention to the frequency of water changes, the speed of fish metabolism in winter is relatively slow, and the pollution of water quality is not serious, and the breeder can reduce the frequency of water changes.

In addition, it is also necessary to pay attention to the amount of water change should not be too large, and the amount of water change should be controlled at a quarter of the total water volume at a time.

Summary. There are five ways to increase temperature: 1. Set up barriers to avoid harm: use wooden bamboo sticks to drive piles on the north side of the fish pond and enclose woven bags or straw straw, and set up artificial barriers to resist the north wind.

2. Manure heating: about 500 kg of livestock and poultry manure is applied per mu of water surface. Fertilizer is used to ferment, decompose, and release heat to raise the water temperature.

3. Smoke and heating: Every day when the north wind is howling is the precursor of frost at night, wet straw and firewood can be piled up on the shore of the fish pond to make a fire and smoke to create a warm atmosphere and reduce the degree of frost.

How to warm the water by raising fish in the north in winter.

Hello, inquiring for you, please wait.

There are five ways to increase the permeability nuclear temperature: 1. Set up barriers to avoid damage: use wooden bamboo sticks to drive piles on the north side of the fish pond and enclose woven bags or straw straws, and set up artificial barriers to resist the north wind of the slippery signs.

2. Manure heating: about 500 kg of livestock and poultry manure is applied per mu of water surface. Fertilizer is used to ferment, decompose, and release heat to raise the water temperature.

3. Smoke and heating: Every day when the north wind howls and shouts rent is the precursor of frost at night, wet straw and firewood can be piled up on the shore of the fish pond to make a fire and smoke to create a warm atmosphere and reduce the degree of frost.

4. Put aquatic weeds. In winter, a certain amount of aquatic plants are put into the fish pond to keep the fish warm in the grass and keep the cold away. 5. Inject water to increase temperature. On a sunny afternoon when the temperature is high, the shallow water sedan banquet that has been warmed by the sun will be stared into the fish pond.

Hello, the above five methods are available, I hope it will help you.

1. Water temperature conditions and adjustment methods: tropical fish is a narrow temperate fish, the requirements for water temperature are more demanding, and the changes in water temperature are also particularly sensitive, and the water temperature that can adapt is 20-30 degrees, and if the upper or lower limit of this range is crossed, it is life-threatening for most tropical fish - if the water temperature drops below 20 degrees, tropical fish will get sick or die; Although the water temperature reaches 20 degrees, if it is low for a long time, it will also affect their appetite and growth; The temperature difference between day and night is too large, such as more than 5 degrees, it can also bring discomfort to them, and it will lead to illness and death over time.

2. There are generally two ways to regulate the temperature of fish farming water: one is to directly warm the water in the aquarium, and the other is to indirectly increase the water temperature by increasing the indoor temperature.

3. Water hardness and adjustment method: The vast majority of tropical fish require to live and reproduce in soft water and low hardness water. The hardness of water is mainly determined by the amount of calcium and magnesium salts contained in the water.

8 degrees is soft water, 8-14 degrees is low hardness water, and 20-30 degrees is hard water.

4. General rain and snow water are soft water; In South China, there are many red loam soils, and the water hardness in the rivers in the rainforest belt is low, and most of them are soft water. The north has low rainfall, high soil salinity, and high water hardness. Tropical fish do not require as much hardness as water temperature, and water with higher hardness can also adapt.

However, water with low hardness or soft water is required for breeding. Tap water is a common source of water for tropical fish farming. The easiest way to judge its hardness is to look at the scale in the kettle after the water is boiled, more is hard water, less is soft water.

5. The pH of water and its adjustment method: The pH of water refers to the concentration of hydrogen ions contained in water. The pH value of water can be measured with a pH test strip or a measuring instrument, and the method of use can be referred to the manual.

6. Bait selection and feeding method: most tropical fish are carnivorous, a few are omnivorous, and a few are herbivorous. Carnivorous fish are further divided into ferocious and mild.

Fierce mouth and fierce temperament, like to eat small fish, small shrimp and earthworms and other large pieces of food, such as Texas leopard, Arowana; Fish with a mild temperament have a small body and a small mouth, and like to eat small animals such as daphnia and midges larvae.

7. When feeding, it should be selectively fed according to the feeding habits of the fish, and the selected food must be fresh, and the natural food should be fresh and frozen. Artificial baits should not be moldy and spoiled. In addition, in order to avoid nutrient deficiencies, the choice of feed should be as diverse as possible as long as the fish can accept it, and the variety of feed should change frequently.
