How to keep fish from dying by selling fish on the beach? What medicine does the vendor use to keep

In order to keep the fish alive while setting up the stall, the following measures can be taken:

1.Having enough fresh water to spare and using larger pots for fish is good for maintaining water quality.

2.Use an oxygen pump to add oxygen to the water to ensure that the fish are able to breathe enough oxygen.

3.Clean up the scales and excrement in the basin regularly to keep the water clean.

4.Throw ice cubes inside the pot, which slows down the metabolism of the fish and allows the fish to survive longer.

5.For some fish that don't need much water, such as blackfish and catfish, just a little water is needed inside the pot to keep it alive.

6.Avoid strong sunlight, and cover the fish pot with a wooden board or other object when the sun is strong at noon.

7.For the remaining live fish, oxygen is continued after the water change to ensure their survival.

8.Establish a recirculating system to dispose of fish excrement and food scraps to keep the water clean.

If this commercial fish wants it to be immortal, it must do the following. First, the fish must be transported only after two days of netting exercise. Second, you must choose fish that are healthy and not injured.

Third, the water in the process of transportation must be the water in which the fish originally lived, and it must be equipped with sufficient pumping equipment. Finally, when you arrive at the market, put it in the fish pond in time, hit the air, and have a water flow, so that the survival rate will be greatly improved.

If you want to keep the fish from dying, it's best to buy an oxygen supply device, so that you can keep blowing bubbles into the water so that the fish don't die.

Set up a stall to sell fish, if you want the fish not to die, you have to have water, and the carriage is prepared with water bags, and the water fish can be pulled up and placed in the market.

Vendors usually use sodium peroxide carbonate or malachite green to keep the fish alive. The former can increase the oxygen in the water body, and at the same time, it will also increase the pH, making the water body alkaline, and the fish will become more active under the dual action of oxygen and water quality.

The substances broken down by this drug turn into oxygen and soda, which are basically harmless to the human body. The latter is different, it is a drug that is strictly forbidden in edible fish and can cause poisoning.

How to keep live fish fresh

1. Blindfold method: When buying fish, soak a piece of tissue paper with water, blindfold the fish's eyes, put it in a plastic bag, and do not have to fill it with water in a plastic bag, so that after one or two minutes, or even an hour, the fish will not die.

2. Liquor preservation method: use a cotton ball, dip it in liquor, stuff it into the mouth of the fish, do not use water, as long as you cover it with a wet towel, you will not die for a few hours. Because the liquor contains ethanol, through the absorption of the gills, it can enter the mermaid's body, which can probably play an anesthetic role.

3. Low temperature preservation method: Sometimes, if you buy too much fish and can't eat it for a while, you can use low temperature preservation method. As long as the fish is washed, put it in a plastic bag or on a plastic tray, put it in the refrigerator freezer to freeze it, and then move it to the low temperature room.

According to the difference in heat preservation and shelf life, low-temperature preservation can be divided into 3 types.

The first is cooling and preservation: the temperature is around 0°. The second is to freeze the freshness at a temperature of -1 -5° to freeze the moisture on the body, and the third is to freeze the freshness

First put it at a low temperature below -25C, and then at a temperature below -18°C, it can be kept fresh for a long time.

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.

Fish stall owners in wet markets usually add fresh water to prevent fish from dying!

If possible, it is best to use an "aerator" to ensure that there is enough oxygen in the water, which is the best way.

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.

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.

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.

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.

Oxygen is supplied by air pumps, and the water is changed after the surplus live fish are sold, and the oxygen supply must be continued. Some black-hearted fish sell fish when they see that the rain is dying, so they add diesel fuel to the water!! It plays a role as a stimulant, and such a fish can jump around in an instant even if it is dying!!

You can't do that!

Cover the fish. Don't let the fish see outside.

Here's how:

1.The lower the water temperature, the less mobile the fish, the less oxygen required, the lower the metabolism, and the safer the transport. However, fish should not withstand drastic temperature fluctuations, and usually the temperature difference should not exceed 5 in an hour.

2.When pulling into fish in summer (fry should not be added with ice), you should not use too much ice cubes when adding ice, and then add ice cubes after the fish is full, so as to prevent the water temperature difference with the pond and fish transport tools from being too large, and not to cool down excessively, otherwise it will cause the fish to die of stress or delay chronic death.

3.The water temperature for transportation is 6 25 is appropriate, and more than 30 will be dangerous. Excessive water temperature leads to enhanced respiration of fish, which consumes dissolved oxygen in the water relatively quickly, which is not conducive to long-distance transportation.

4.When the water temperature is too high or when it is transported in the high temperature season, the water temperature can be adjusted appropriately by using ice cubes or freezing thermostatic cars, etc.

5.When the seedling temperature is adjusted, it can not be directly cooled in the seedling equipment (such as oxygen bags, water tank cars, etc.), and ice cubes can be placed outside the equipment or adjusted by using methods such as refrigerating constant temperature cars or air conditioning in the car, and the cooling range can not be sharply lowered or raised, and the temperature must be adjusted slowly.

6.Transporting fish during the high temperature seasons of summer and autumn is best done at night.

Hello, raising goldfish is particular, if you really want to make money by selling it, in the long run, it is recommended to learn the same if you raise and keep goldfish, here are some suggestions for you:

First, to avoid the death of goldfish, the control of water temperature difference is the first key element.

Second, to avoid the death of goldfish, you must not feed too much. It must be quantified at regular intervals.

Third, to avoid the death of goldfish, try to avoid a complete and complete water change. Because, it is not easy to raise a tank of good water.

Feed two days after entering the tank. It is best to use live fish and insects for feeding. If there are no live fish insects, frozen fish insects or finished fish feed, it is also possible.

The amount of feeding should be grasped well, and it is advisable to be able to eat it all within half an hour to an hour. Start with as little as possible, gradually increase the amount, and basically determine a relatively fixed amount of feeding per day through three to four days.

Feeding is timed and quantitative. Goldfish are small creatures that don't know how to be hungry. If the food is plentiful, it will eat non-stop.

Some may die of fullness; If you don't eat it for a long time, the food residue will spoil the water quality and cause the goldfish to get sick. All in all, feed less, feed often, but not without. Feed at least once a day and no more than three times a day.

Occasionally, if you are not at home, you will not have a problem if you don't feed it for a week or so. But the baby goldfish does not have enough food and the individual does not grow.

Change the water appropriately. Aquariums with filtration equipment pump out more than one-fifth of the water every week and add new water that has been dried for more than three days and has a comparable water temperature; In a mud tank without a filtration device, use a straw to extract the dirt at the bottom after a while, and then add the same amount of fresh water that has been dried.

Are you selling? On the street? Shop? Or go wholesale?
