How do you keep fish to keep them alive longer?

Note that if the water used for fish farming is tap water, it will be left for a day, that is, 24 hours before it can be used for fish farming. Pay attention to feeding and put some aquatic plants. 1. Feeding environment, you can choose fish tank or fish pond breeding.

Different fish, the requirements are also different, if it is a goldfish, goldfish is a cold-water fish, the demand for oxygen is great, enough space and dissolved oxygen is the key to ensure the healthy growth of the fish. 2 Water quality, most common ornamental fish have strong adaptability to water quality, so the water quality in most parts of China is suitable for breeding. For those of us who are aquarium fish lovers, "raising fish first and raising water first" is a wise saying, and it is convenient to raise fish after raising water.

3 Feeding, many people will ask, how many times a day should I feed? In fact, there is no standard answer to this kind of question, don't feed blindly, and change it according to the situation. For the fish that you have just bought, don't rush to feed them, and feed them after 1-2 days.

Most of the fish raised at home are fed feed, and the feed is not as good as live bait, so we should often feed some fish insects, water earthworms, etc., which not only fish love to eat, but also help fish color. It is best to soak and disinfect the live bait with potassium permanganate, and then wash it before feeding the fish. Feeding once or twice a day is fine, without overfeeding.

Live bait can be fed more, and the fish will eat their own proportions and will not be full. Fish will die because they eat artificial feed, and the feed will swell when exposed to water. After the fish eats the feed, the feed swells in the stomach, so the goldfish survives.

If you can't grasp the amount of feeding, you can feed the feed equivalent to the size of the head of the fish 1 2, so that not only the fish will not be hungry, but also not easy to die. When you can grasp the amount of feeding in the future, you can increase or decrease the amount of feeding yourself. If the fish are sick, they should be fed less or at a later rate to avoid waste or water quality.

4. Change the water, generally you should change the water about once a week, and it can be longer in winter. Generally, it is enough to change 1 to 3 at a time. Carry out a full tank water change every 1-2 months.

If there is a sudden lack of water or the water is easily dirty, you should immediately change the water completely and adjust the water change time according to the actual situation. The new water that has been cooled must be used to change the water, and the water temperature cannot be plus or minus 2 degrees related to the water temperature of the original tank. Another:

In order to prevent fish diseases, we should prepare some common medicines, so as not to need them from time to time, generally the following medicines can ** most of the common fish diseases, you can use different drugs according to your own needs. Salt: It will be available at home, which can be disinfected and can also prevent and control a variety of ** or gill protozoan parasitic diseases, water mildew and bacterial fish diseases.

Furazolidone (also known as dysentery): It has a broad-spectrum antibacterial effect, is most sensitive to Escherichia coli and dysentery bacilli, and is effective against gram-negative bacteria. Potassium permanganate:

Disinfect fish tanks or utensils. Effective against parasitic or bacterial diseases. When soaking fish, the concentration should not be too large, because potassium permanganate has a certain corrosiveness and is very harmful to the gills.

Gentamicin: It is also a very commonly used fish medicine, gentamicin is used together with dysentery, ** enteritis effect is better.

Pay attention to the water quality and temperature, and then don't overfill the fish, sometimes sprinkle some salt when changing the water, so that it can be poisoned first! If you want to raise fish, you must first raise the water well! Wish.

The most important thing is that you take care of the water, the water is ***, and the fish will live naturally for a long time.

Maintain a stable environment: If you want fish to live longer, you need to make sure that the environment in which they live is stable. Because the environment fluctuates too much, it will have a certain impact on their health.

Adequate oxygen: It is also necessary to ensure that the fish have enough oxygen to grow, only with sufficient oxygen can they survive better.

Regular check-ups: Breeders should also check their bodies regularly and immediately after discovering diseases to avoid diseases affecting the lifespan of the fish.

1. Change the water regularly: As the saying goes, "fish farming starts with water", and water is very important to fish. When breeding ornamental fish, it is necessary to pay attention to their clean water quality, and usually pay attention to the frequency of water change, neither too high nor too low.

2. Reasonable feeding: most of the ornamental fish do not have a sense of satiety, and the amount of feeding should be paid attention to when breeding. Usually, you can feed until 8 percent full each time to avoid enteritis.

3. Control the temperature: When breeding ornamental fish, you should also pay attention to the water temperature in the fish tank. It is best for the keeper to adjust the temperature according to the habits of the fish, so that it is more conducive to their growth.

Pay attention to the water quality and temperature, and then don't overfill the fish, sometimes sprinkle some salt when changing the water, so that it can be poisoned first! If you want to raise fish, you must first raise the water well!

The most important thing is that you take care of the water, the water is ***, and the fish will live naturally for a long time.

Live fish preservation method: put live fish or fresh fish in 2% salt water, after 10 15 minutes, which can inhibit the growth of bacteria, generally at a temperature of about 30, the preservation time can be extended for a few days, and it will not deteriorate and rot.

In addition: (1) Sticking moist paper on the eyes of live fish can make the fish survive for 3 to 5 hours, because there is a "death line" behind the optic nerve in the fish eye, and this line will break as soon as it is out of the water, and the fish will die. If you put wet paper on the eyes of a live fish out of water, it can delay the breaking of the thread and the death of the fish.

2) Pour a few drops of liquor into the mouth of the live fish, then put the fish into a basin with a net and put it in a cool and dark place, so that the fish can live for a longer time.

3) Put the fresh fish in hot water at about 90 degrees, blanch for 2 minutes, take it out, and then put it in the freezer of the refrigerator to freeze it. After such treatment, the bacteria on the surface of the fish are scalded to death, and then frozen in the refrigerator, the bacteria will no longer multiply. 2 After 3 days, the fish is cooked and tastes as good as if it had been killed alive.

What causes goldfish to die? How to make your goldfish live longer.

Fish tank in advance wash and put the water after putting some special salt for fish farming, water put on two or three days after and then buy fish to put in, tropical fish is best to use a small fish tank, koi fish with a large tank less fish, novices are best to seek refinement do not seek quantity, tropical fish need the temperature in the house about 20 degrees, koi fish is best not to exceed 20 degrees, otherwise it is easy to lack oxygen, feed once or twice a day, how much to eat depends on the size of the fish and how much to determine, I generally rely on feelings, but the recognition of it is not enough to feed more, fish water does not need to be changed, It looks very turbid and has an unpleasant smell then it must be changed, each time the water must be put on the two or three days on the clear water, each time the water must be changed must also add a small amount of special salt, it is best to buy some water plants without roots floating in the place, both good looking and can improve the water quality small fish very like, when buying fish must pick the kind of healthier, no scales, love to swim fish, although I am not professional, but I am very fond of fish and flowers, I don't know if I can help you, you can learn from it!

Filtration system + aquatic weeds, you will find that the fish is too difficult to die, it is not an exaggeration, the purification effect of aquatic weeds is extremely powerful, and you can play the role of aquatic weeds. It is recommended that you take a look at the Qingsen Aquarium, which has a lot of tips to teach you how to raise fish.

How to keep fish alive for a long time.

1 feeding method.

First of all, it is necessary to prepare the fish container, and dry the water in advance, if you want to spread sand and plant grass, you need to add the water slowly after everything is ready, and it takes about one or two days to dry the water. The goldfish are then placed in the aquarium in a plastic bag containing the "old water" and suspended in the pelagic layer of the water body, and after about half an hour, it is estimated that the water temperature in the plastic bag is close to that of the aquarium. At the same time, add 1 teaspoon of salt to the water to sterilize.

Wait for the fish to acclimatize to the aquarium for 1 to 2 days before casting the bait. If it is necessary to increase the stocking amount, the new fish should be kept in another container for 7-10 days, and after observing that the fish are indeed disease-free, they should be reared together with the fish in the original aquarium to avoid the introduction of pathogens.

2. Bait method.

There are generally two kinds of bait during the goldfish breeding period: artificial bait and natural bait. The bait must be strictly timed and quantitatively to keep the water fresh. Generally speaking, the number of bait should be 1-2 times a day, 1 time in the morning and 1 time in the evening, and 1 time in the evening should be early rather than late.

1) When the weather is sunny, the day is warm and the wind is warm, the dissolved oxygen in the water is sufficient, and the water temperature is suitable, you can put more bait appropriately.

2) When the water quality is thin and the fish has a strong appetite, you can put more bait.

3) If the fish is sick, or the species is delicate and precious, you should put less coarse bait and some fine bait instead.

To distinguish how hungry and saturated the goldfish is, the digestion and absorption can be distinguished according to the color of the fish feces. If the fish feces are green, brown or black, it means that the fish is suitable for feeding and is well absorbed. If the fish droppings are white, it is a sign that the fish is overfed.

3. Master the time and method of feeding.

Make sure to eat within 1-2 hours of feeding every day, not too much. Feeding time: Spring and summer should be around 7 o'clock in the morning, when the sun begins to shine on the fish tank, late autumn and winter should be fed at about 8 o'clock, and in severe cold can be fed at 9-10 o'clock.

Remember, you can't feed in large quantities in the evening, and even if the goldfish are visibly feeding, they can only feed in small amounts around 3 p.m. In addition, blister-eyed, Chaotianlong and other species of fish, foraging activity is poor, as much as possible to take care of some, feed some live fish and insects.

4. Pay attention to the amount of fish you eat.

For fish with a large amount of activity and strong vitality, you can feed more. On the contrary, vote less; If the goldfish eats within half an hour and is still foraging, it means that the feeding is too little, and the next day can be increased until the goldfish is eaten in 1-2 hours, and there is no foraging or "floating head" phenomenon means that the feeding is just right, if the 3 hours can not be eaten and there is a "floating head" phenomenon, it means that the feeding is too much. Note that goldfish eat a little bit of hunger, and fresh food is good for goldfish health.

Fish farming starts with water. The household water we commonly use is tap water, which is stored in natural water, purified and disinfected with chlorine, and then becomes the tap water of our life. Although tap water in Japan is much purer than in other countries and can be drunk raw, it is not used to raise fish.

Because of the small size of the fish, it is harmful to put it in tap water mixed with chlorine. The chlorine contained in tap water can be neutralized with sodium thiosulfate also called baking soda, so the neutralized tap water can be used to raise fish, so sodium thiosulfate (also known as "Haibo") is a treasure for fish farmers. The dosage is 1 to 2 capsules per 10 liters of tap water, as excessive use can be harmful.

If you still have time before you release the fish, you can fill the basin or bucket with tap water and let the sun shine for more than 10 hours or about a day to make the chlorine in the tap water disappear, and then put the fish in. This is called the solar irradiation method. However, you can also use the natural water purification method, which is to connect the bucket to the tap water, leave it for 24 hours, and wait for the chlorine in the tap water to disappear before using it.

In fact, if the water quality is well controlled, the fish will not get sick if they are fed well.

Change the water often, feed it fish and bugs, try not to let the water get too cold, and don't forget to check often.
