How do you sell fish to make it difficult for fish to die? How to prevent fish from dying when selli

Oxygen is supplied with an air pump, and the fish does not die in the presence of oxygen. After selling the remaining live fish, oxygen will continue to be supplied after the water is changed. If you want the fish not to die, you must have a pump that matches the fish tank, and you need to change the water regularly, about once every two or three weeks, and change one-third to one-half of the water each time.

At noon, when the light is strong, the fish should be shaded, which can be covered with a wooden board, and should not be exposed to strong light, otherwise it is easy to die.

The fish market buys a kind of "chlorine" like a drug, scatters it in the water to be released in proportion, stirs it, and waits for the chlorine gas to disappear before releasing the fish. If the water is stagnant, it is necessary to put the fish water in the tank for more than a week.

Water oxygenation: The water tank should be equipped with an oxygen machine and water filtration.

Don't feed: Never feed.

Remove excrement promptly: Keep the tank water clean.

The density of the fish must be appropriate, and do not put too many fish in the tank.

When selling fish, if you want to make it difficult for the fish to die, you must first change the water for fish farming regularly, so as to ensure that the water can be relatively clean and the oxygen in the water is relatively sufficient.

The second is to have an oxygen pump to replenish oxygen in the water at all times, so that the fish are not easy to die.

In order to maintain the freshness of the fish, when selling fish, fishmongers have to give oxygen to the fish, so that the fish is not easy to die.

I don't know what you mean by not being easy to die, how far it has lived? Let's talk about the primary one first: the fish you buy (take) back must be healthy, at least not floating on the surface or sinking to the bottom; The fish has white spots, ulcers and the like.

The second point: the tank where goldfish are kept must be clean. The third point:

The water quality requirement is best to leave tap water for a period of time (preferably more than a day, let the bleach in the water evaporate. ）。As for why we don't use well water and river water, I will talk about it below.

Point 4: Don't put the goldfish in the tank immediately after you buy it. Fifth point:

Do not feed goldfish in the tank right away. Point 6: If you want to place aquatic and sand stones in the fish tank, be sure to disinfect the fish for a period of time after placing it.

Point 7: Before putting fish in the tank, sprinkle some salt to disinfect it. Basically, when these are done, the goldfish will be able to live.

Next, let's talk about advanced and a supplement to the above First: Why do we use tap water for water quality? That's because, first, fish are more delicate nowadays.

Unlike in the past, the fish were harvested from the sky and had strong disease resistance. Today's goldfish are weak and delicate, and their resistance to water quality and germs in the water is weak. So it is not suitable for well water.

Because the well water has not undergone a disinfection and filtration process, there are too many native microorganisms in the water, which can easily cause goldfish to get sick. Second, the well water contains too many minerals, which is not good for the growth of goldfish. Third, there are a lot of goldfish in other places now, which means that the goldfish you buy locally are shipped from other places.

And not through locally farmed goldfish. The requirements for water quality are relatively high. Do a simple little experiment and know that there is no taste in drinking tap water and tasting it carefully.

But if you drink a well water and taste it carefully, you will find that the well water has a taste, which is either sweet, salty, or bitter...The same is true of rivers and rivers. Second:

Why can't goldfish be put into the tank right away? That's because the water you are holding the fish in the tank is at a different temperature, and the fish is likely to have an irritated reaction due to the difference in water temperature, which is the old saying that you will catch a cold and die. So the correct way is to put the fish and the water containing the fish into a bag, put the bag as a whole in the fish tank, so that the water temperature is naturally the same as the water temperature in the fish tank, and then put the fish into the fish tank.

Third: Don't feed the goldfish you just got back, because if you feed it immediately, either the fish will not eat and cause the water pollution of the fish tank and the lack of oxygen will die, or the fish will eat it, but it will die because it is not adapted to the environment. Fourth:

It is necessary to always pay attention to the reaction of the fish in the fish tank, for example, the fish often put their heads out of the water, which is also known as floating heads, which means that the fish tank is hypoxic, which will cause the goldfish to die of hypoxia or cause other diseases due to lack of oxygen. If the back of the fish often floats on the surface of the water, it means that the fish has rotten belly, and the internal organs decay and produce gases and die. If the fish often sinks to the bottom, there is a problem with the swim bladder.

You won't drown, but you'll be able to die easily. Then there is gill rot, which basically does not happen and can be skipped. The most common are white spot disease, powdering, and white spot disease is present in fish.

The main cause of fish death when selling fish is chlorine in the water, which kills the fish.

1. You can go to the fish market that sells tropical fish to buy a drug like "chlorine", scatter it in the water to be released according to the proportion, stir it, and wait for the chlorine gas to run out, and then release the fish. If you are stuck in the water, you should put the fish water in the tank for more than a week, so that you don't need to put medicine, but it will take a long time.

2. Water oxygenation: The water tank should be equipped with an oxygen machine and water filtration.

3. Don't feed: Never feed.

4. Remove excrement in time: keep the water in the tank clean.

5. The density of the fish must be appropriate, and do not put too many fish in the tank.

It is to let the fish live in the water, the water temperature should not be too high or too cold, and keep the water clean, there is a large fish pond can use an aerator or stir the fish pond to let the water in the fish pond contact with the air, keep the water microbial community stable, and the life of the fish should be longer.

If you want the fish to die easily, you can add some oxygen to the fish pot and feed some fish food from time to time.

The fish died because of the lack of oxygen, and the chlorine in the water killed it. In order to keep the fish from dying, it is necessary to increase the oxygen pump to reduce the water pressure.

The fish seller wants to make it difficult for the fish to die, of course. Give him a constant supply of oxygen!

Aerator aeration and frequent water change.

The density of the fish must be appropriate, and there should not be too many fish in the pool. When changing the water, leave some water in the original pool, so that the fish can adapt faster. It is best not to feed, if you must feed, you must regularly and quantitatively set a point, once or twice a day, 3 to 5 minutes each time, and the feed that cannot be eaten within 5 minutes at most should be fished out in time.

Those who sell tropical fish can use auxiliary items such as chlorine removal, scatter them in the water to be released in proportion, stir them moderately, and wait for the chlorine gas to disappear before releasing the fish. If the water is stagnant, it is necessary to put the fish water in the tank for more than a week. The water tank should be equipped with an oxygen machine and water filtration.

The quality of the freshly slaughtered fish is not the best, because the fish will have a "deacidification" process, which needs to be left for a while to be more delicious. Small fish such as grass carp and silver carp should be refrigerated immediately and cooked after 2 hours; Whereas, large fish need to be refrigerated for more than 2 hours.

The size determines the taste and safety of the fish. If the fish is too small, it means that it has not grown up and matured, the meat is not tender enough, and there are many bones. Fish that are too large are old and have rough flesh.

Therefore, it is more appropriate to buy fish about eight points large, for example, carp and Wuchang fish should be 1 and a half catties, crucian carp catty -1 catty, and grass carp 4-5 catties.

How to sell fish to make fish not easy to die:

1. First of all, there should be an aerobic pump to ensure that the oxygen is sufficient.

2. Keep the water temperature low. Keep the fish tank in a cool place. If it's not cool on the street, fill a bottle of mineral water with ice cubes and put it in a fish tank. The amount of ice depends on the capacity of the tank and the number of fish.

Have an aerobic pump to ensure that there is enough oxygen.

Users need to pay attention to some contaminated fish, the body will be deformed, such fish is likely to be enriched with harmful pollutants to the human body, so knowledgeable diners will not buy these deformed fish, do not try to buy deformed fish cheaply.

When users find out and question, if the fishmonger is providing slaughtering services, the fish stall owner will make an excuse that it is caused by the greasy hands that fell into the water when the fish was slaughtered. In fact, it is indeed difficult to kill the greasy oil on the surface of the fish pond, but the oil star brought by killing the fish does not have a rancid smell, and the minced rotten meat has nothing to do with killing the fish.

In general, in the summer, the fish solution is hypoxic, and the oxygen concentrator should be used.

If that doesn't work, buy some fish spirits.

It can be increased by an oxygenator and coarse salt is added to the water at the same time.

What kind of medicine should be put in selling fish, so that the fish is not easy to die?

The pro needs to put some chlorine remover.

The fish that sell fish do not die may have added sodium peroxide carbonate or malachite green to the water.

Sodium peroxide carbonate can increase the oxygen in the water, even without oxygen, it can ensure that there is enough oxygen.

Malachite green has a good ** effect on most diseases of fish, and even sick fish will become in better condition.

The farmed fish that sell fish will also die, but they have more experience in raising them, so the mortality rate will be much lower.

1. Control the water temperature: In order to avoid fish death, you need to adjust the water temperature according to their habits. Fish are thermomorphic animals, and they change their temperature with the change of water temperature, so when the temperature changes greatly, they cannot adapt and are prone to death.

2. Reasonable feeding: Many breeders will feed a large amount of food in order to make the fish grow bigger when raising fish. However, most of the ornamental fish do not have a sense of satiety, and if they are fed too much food, they are prone to death.

Some sodium peroxide may be added to the water in which the fish is sold. When they encounter water, they will have a chemical reaction and release oxygen, so that the water in the fish pond can keep enough oxygen, and the fish will not die easily.

If it is an aquarium fish, some malachite green or methyl blue may be added, which can not only resist diseases, but also kill bacteria.

If it is edible fish, you cannot use guppy stone green and methyl blue.

1. Keep enough oxygen: If you want fish to survive more easily, you need to ensure that they have enough oxygen to live. They can only remain active if there is enough oxygen.

2. Clean in time: clean up the garbage for the fish in time, so as to ensure that the water quality of their lives is clean and refreshing. In addition to this, it is necessary to change the water regularly and keep the water clean.

3. Mix the right water: If it is a marine fish, it is necessary to use sea salt or seawater to prepare the right seawater, so that the fish can live more comfortably.
