Should you put crayfish in the water after you buy them and how many days can they be raised in the

Once a live lobster is bought, it can be placed directly in a basin of water.

Add a pinch of salt, drizzle a few drops of cooking oil, don't feed anything, and you can keep it for two or three days.

Not only can it keep the lobster fresh, but it can also make the lobster spit out the sediment in its body.

Crayfish are more aggressive, so try to spread out in a large basin, put an appropriate amount of water in the large basin (the water surface should not be lower than the top of the crayfish's head, it can be about 2-4 cm), and put in an appropriate amount of water This can not only reduce the number of deaths, but also allow the crayfish to discharge garbage from the body. The large basin is to leave space for the crayfish to move around. And crayfish prefer dark and damp places, you can cover the basin with a black plastic bag or other things, so that they can sleep as peacefully as possible, reduce the state of tension can also reduce the probability of fighting.

During the period of raising crayfish, you can give it some green cabbage leaves, steamed buns, and diced meat to eat.

Crayfish should not be put in the water when they are bought, because they can't be raised in the water for a day, so they are put in a dry place.

The vitality of the crayfish is very strong, it can live on land, you can put it in the water, but don't put too much in the water, almost an inch or so of water is fine.

Should crayfish be kept in water for a few days after they are bought? When you buy crayfish, check whether the belly of the crayfish is clean and clean. If you observe the belly of the lobster with the naked eye, if you are not in a hurry to eat, if you have the conditions, Brother Yang is best to use clean water for one to two days, I think in the process of speaking, change the water once a day.

Of course, when buying crayfish, if the belly of the crayfish is black and dirty, you will definitely not buy it. Like you said, if there is a condition. If the crayfish is bought, try to raise it in water for a day or two days.

Crayfish can be put in the water or not in the water when they are bought. However, it is best to dispose of it as soon as possible so that the ingredients will be fresh and taste more delicious.

You can put the crayfish in the vegetable washing pool, put a little water, don't overflow the shrimp, just a light layer at the bottom of the pool, I have tried, you can put it for five or six days.

If you don't keep it up, the crayfish may crawl everywhere, and it can also prolong its life, and the crayfish can only be raised in the water for a maximum of three days.

It is best to keep crayfish in water for about half a day, and you can add some salt to the water, so that you can remove the dirt on the cheeks of crayfish.

If you don't want to deal with crayfish at the moment, you still need to put them in water for a while, but if it is under normal circumstances, you can raise it to a maximum period of 1 or 2 days, and there will be problems after a long time.

Crayfish still have to be put in the water.

Eat it fresh, don't leave it for a long time.

Crayfish can be put in the water or not in the water when they are bought. But as soon as possible to deal with the food, so that the ingredients will be fresh, the taste will be more delicious, you can put the crayfish in the vegetable washing pool, put a little water, do not overflow the shrimp, just a light layer at the bottom of the pool, you can put it for five or six days.

If you don't want the crayfish to last too long, you can do it for 2 or 3 days. First of all, after buying the live lobster, you can directly put it in the water basin, add a little salt, pour a few drops of cooking oil, don't feed anything, you can keep it for two or three days, not only can keep the lobster fresh, but also make the lobster spit out the sediment in the body, and reduce a lot of trouble for cleaning the crayfish.

Need. However, the water for raising crayfish should choose overnight tap water, and using tap water directly will accelerate the death of lobsters. It is also possible to use pools and glass fish tanks for short-term lobster farming, first rinse the lobster cleanly, and then pour the lobster directly into the pool with a ventilation pump, or a glass tank for oxygenation, which can be kept for about ten days.

Before eating, put the crayfish directly into the water mixed with vinegar and salt, soak for 15 minutes, force the lobster to spit out the dirt on the gills, basically the crayfish after soaking is already very clean, and then rinse with water 3 times. When cooking crayfish, brush the surface of the crayfish, then remove the stomach of the shrimp head, and then pinch the tail in the middle of the tail with your hands and twist it left and right until it is broken, and then slowly pull out the shrimp intestines.

Spicy crayfish method: Clean the crayfish, blanch it with boiling water, and remove the shrimp line. Prepare bay leaves, cinnamon, dried chilies, star anise, fennel and other spices, put oil in the pot, add spices after heating, add garlic cloves and stir-fry to make fragrant, add crayfish and stir-fry.

Add a small amount of beer, add an appropriate amount of soy sauce and water, add an appropriate amount of salt, and stir-fry.

Spicy thirteen spiced crayfish method: crayfish to the gills, to the tail to clean, if you feel that it is still not clean, then the head and tail are all removed, the green shrimp must be fried with hot oil to slide, the meat is firmer. Heat the oil, add the green onions, ginger, garlic, peppercorns, stir-fry until fragrant, then add the hot pot base, and the bean paste, and fry the bean paste into red oil.

Add the fried shrimp, add white wine to stimulate the aroma of the seasoning, and then add salt, thirteen spices, and a bottle of beer. Reduce heat to low heat and simmer for 20 minutes. Add sugar, monosodium glutamate, chicken essence, cumin powder, green pepper.

Stir-fry to taste.

Crayfish can be left out for 2 days.

Put the crayfish into a basin of a suitable size, then pour in an appropriate amount of water, add a little ice cubes, cover the top of the basin with a breathable rag to ensure air circulation, and at the same time avoid smell, and finally put it in the refrigerator freezer, the temperature is about 1-2 degrees, reduce the activity rate of crayfish through low temperature, and keep live crayfish for 1-2 days, similar to the usual method of preserving fresh crabs.

Lobster Nutritional Value:

Lobster is rich in high-quality protein, and the meat is soft and easy to digest, which is a better food for some people who are weak. Lobsters are relatively nutritious, and regular consumption has the following benefits for the human body:

1. Lobster is sweet and salty and warm, enters the kidney meridian, can benefit sperm and blood, tonify kidney yang, nourish yin fluid, have the effect of tonifying the kidney and strengthening yang and nourishing yin, and has a certain alleviating effect on some symptoms such as impotence and kidney deficiency and tetany.

2. Lobster has a sweet taste, peaceful medicinal properties, and can calm the liver and calm the heart, calm the nerves, and have a certain effect on some symptoms such as neurasthenia and insomnia.

3. Lobster is fresh and appetizing, has the effect of strengthening the stomach and eliminating appetite, and has an auxiliary effect on some symptoms such as weak stomach and loss of appetite.

The main spicy component of mustard is mustard oil, which has a strong spicy taste that can promote the secretion of saliva and gastric juice, has an appetizing effect, can enhance people's appetite, promote digestion, and promote metabolism.

With the right method, it can be stored for at least 3-5 days!

After the live lobster is bought, it can be placed directly in the water basin, add a little salt, pour a few drops of cooking oil, do not feed anything, and can be kept for two or three days, which can not only keep the lobster fresh, but also make the lobster spit out the sediment in the body.

Storage method 1: It is better to store in a foam box, the plastic foam box is both breathable and windproof, and the shrimp are lined up with the belly down (the belly is easy to die) Each box puts about 30 pounds of lobster, rinse it clean with water, and then add snowflake ice (smash the ice cubes into pieces) Add ice to each box 4 - 5 pounds, and finally cover the lid and put it away. Do this with ice once in the morning and once in the evening.

This method of storage can store lobsters for 5 days to 1 week.

Storage method 2: After rinsing the lobster, pour it directly into the pool or glass tank with an air pump to inject oxygen. Don't put too much lobster. Change the water in the morning and evening. This method of storage allows lobsters to be stored for 5-10 days.

Broodstock cultivation.

The area of the broodstock pond is about 1200m2, the bottom is good to loam, the water depth is about 1m, the width of the pond ridge is more than 1 5m, there is sufficient and good water source, the injection and drainage outlet are built, and the surrounding pond ridge is built with plastic film or calcium-plastic board to prevent escape from the wall, and the pond is disinfected with 50-60kg mu of quicklime dry pond 7-10 days before stocking. After disinfection, it is filtered (to prevent wild trash fish from entering the pool) and injected to a depth of about 1m, and 500-800kg of rotting livestock and poultry manure is applied to fertilize the water quality. In the pond, people are placed in the pond for shrimp to climb and inhabit, such as branches, roots, bamboo tubes, etc., and some aquatic plants are transplanted.

The broodstock pond can be put into 40-60kg of broodstock mu, and soaked in 3 salt water for 10 minutes before stocking to kill pathogens. In order to make full use of the water body and regulate the water quality, 50-100 acres of silver carp and bighead carp can be mixed at the same time. During the cultivation period, fresh aquatic plants, soybean cakes, wheat bran or compound feed can be fed, and a part of animal feed can be added.

Such as chopped snail mussel meat, livestock and poultry slaughtering scraps, etc. Daily feeding amount: 2-3% of the broodstock body weight in March, 4-5% in April, 6-8 after May, feeding 1 time in the morning and evening every day, mainly in the evening, accounting for 70 of the daily bait.

At the same time, strengthen water quality management, change new water every 10-15 days, and change water 1 3 every timeSplash 10-25g m2 of quicklime with water once every 20 days to maintain good water quality and promote the development of broodstock gonads.

So it can be seen that it can be raised in water.

Yes, there should be no problem with fresh water, but if you keep it for a long time, you can still see it come out of its shell.

There are several ways to do this:

1. After the live lobster is bought, it can be put in water, add a small amount of salt, drop a few drops of cooking oil, and do not feed it, so that it can be stored for two to three days, which can not only ensure freshness, but also make the lobster spit out the mud in the body.

2. Wash the lobster, put it in a pool or glass tank with an air pump, and change the water in the morning and evening to store the lobster for five to ten days.

<> lobsters can generally be kept for 1 day if they are semi-immersed in water, and if the water is excessive, the lobsters will be suffocated because they cannot breathe. In addition to the need for suitable water depth, the water temperature should be kept at 24-30, not lower than 20 or higher than 32, the pH value of the water quality should also be kept between, and new water needs to be injected frequently, and the transparency of the water should be kept at about 30-40cm.

1. Can lobsters be raised in the water for a day?

1. If the lobster is semi-immersed in water, it can generally be raised for 1 day, but if it is cultivated in a lot of water, it usually dies quickly, because the lobster breathes a lot, and if there is too much water, it is easy to be suffocated.

2. The water temperature suitable for the growth of lobster is generally 24-30, when the temperature is lower than 20 or higher than 32, its growth is hindered, and when the water temperature is below 15, the survival rate of lobster larvae is very low, so in addition to the need for appropriate water depth, the right temperature is also needed when breeding.

3. When raising lobsters, it is necessary to keep the pH value of water quality between, generally not higher, and it is necessary to inject new water frequently to keep the transparency at about 30-40cm.

Second, how deep the water needs to be put to raise lobsters

1. The water depth of lobster breeding is generally, because lobster belongs to crustaceans living in shallow water areas, such a water depth can make the temperature difference between the upper and lower layers of the water body small, and the segregation file is more conducive to the growth of lobsters.

2. Breeding lobsters in different places, the water depth of breeding is also different, for example, if you breed in a small pond, the water depth is generally 50cm-1m, if you are breeding in rice fields, the water depth is generally 10-20cm, so the specific breeding water depth needs to be determined according to the actual situation.

3. Different seasons, the requirements for the depth of breeding are also different, if the water is cultivated in spring, the water level can generally be controlled in, because the shallow water is used for lobster seedlings to shell and the growth of aquatic plants. In the summer when the water temperature is higher, the water depth can generally be kept in, which can help the lobster survive the high temperature season, in the winter, whether it is pond farming or rice farming, the water level should not be too deep, the water level of the ring ditch is generally 80-120cm, and the water level of the terrace is generally about 30-40cm.

Crayfish are bought and poured into water, and ice cubes can be raised until the next day.

The washed crayfish did not remove the head line of the crayfish, the crayfish was just cleaned on the surface, and it was still alive at the moment, so the crayfish were directly raised in the pool, which could be stored until the second day, and then continue to cook the crayfish on the second day.

If the head of the crayfish and the shrimp line of the crayfish are removed, and the crayfish has been cleaned, the crayfish is dead at this moment, and the crayfish cannot be put in the refrigerator freezer. You need to put the crayfish in a crisper bag or crisper box, and then put the crayfish in the freezer of the refrigerator to freeze.

In the low temperature environment, can inhibit the reproduction of bacteria, can prolong the crayfish as much as possible without deterioration, to say that crayfish is a delicious and delicious food, the current way of cooking disturbing the wheel is particularly much, many friends like to eat crayfish, in fact, crayfish can be steamed, boiled, grilled, fried, to say that the taste of crayfish is very good, but before eating crayfish, the crayfish need to be cleaned, and the cleaned crayfish should be eaten as soon as possible.

The selection of small dragon slow letter shrimp

1. Season: The best time to eat crayfish is from May to October, the yellow meat is full of fat, and even the three knots on the big chela are stuffed from head to tail with elastic teeth and snow muscles.

2. Color: Look at the crayfish is clear water is muddy water, look at the back, red and clean, this is acceptable, and then open it to see its belly fluff and claws on the hair, if it is white and neat, it is basically raised by clean water quality.

3. Size: We try to buy lobsters that have just grown up, too small, after all, the food is tasteless, touch its shell with your hands, the iron is hard and hard is the old one, and the elastic one like a nail is the shell that has just grown up, so we have to buy a soft shell.
