Why does seafood die so easily?

Because seafood is something that lives in the sea, if you take it to the shore, if there is no water, then it will definitely die, because it is a creature in the sea, so even if you take it to the shore, and then put some water to raise it, then he still can't adapt to it, he is still hard or the sea water is its nature, so I think the seafood must be eaten a little fairy, and then you must not eat the dead seafood, that kind of seafood may get sick if you eat it. Therefore, it is better to eat less seafood, because eating too much is not good for the body.

Because most of the seafood lives in the water, they will die when they leave the water, so the seafood is quite easy to die, and we must not buy dead seafood when we buy it.

Seafood is in the sea, and the pressure is different after it is salvaged from the sea, so it will die. If the density of the water is different when farming, there will be deaths.

Because many of the fish, shrimp and crabs in the seafood originate from the deep sea, when they come out of the deep sea, they will die quickly because of the difference in pressure.

The main reason is that seafood generally does not live long, and they all live in water, and they can't live without water.

Seafood has very limited living conditions, and it will die without the ocean, and it will die without seawater and nutrients.

Dead seafood, fish and shrimp are edible, except for crabs and shellfish, but the premise is not to store them for too long.

Dead seafood is edible. The seafood in the market is basically dead, because most of the seafood lives in the deep sea, and when it is caught, the water pressure decreases, causing the seafood to die, so the dead seafood can be eaten.

Dead seafood is certainly edible. Because the meat is still very tender when the seafood dies, it does not affect the taste of the seafood, so it can be eaten.

No, this kind of food is very dangerous, and there are some parasites in it, which will affect the health of the body.

It can be eaten if it has not been dead for a long time and the taste and color have not deteriorated.

The most feared thing about seafood is salt. Seafood, also known as seafood, includes fish, shrimp, shellfish, etc.

Related information. 1. The concentration of salt is too high. We know that seafood lives in the sea, and the seawater has its own salt ingredients, but the salt concentration is dozens of times higher than that of the seawater.

2. As long as the seafood is an edible animal or plant raw material produced in the sea, it is commonly referred to as seafood. Among them, shellfish and limbs (shrimp, crabs, etc.) contain high purines, and drinking beer and eating this type of seafood is more likely to suffer from gout. Although seafood is rich in nutrients, it should not be eaten too much.

Seafood contains toxins and harmful substances, and excessive consumption can easily lead to damage to the spleen and stomach and cause gastrointestinal diseases.

3. Drinking tea after eating seafood grows stones. The reason why you should not drink tea after eating seafood is similar to the reason why you should not eat fruit. Tea contains tannic acid, which can also form insoluble calcium with calcium in seafood.

Eating seafood before or after eating it increases the chance of calcium combining with tannic acid. Therefore, it is best not to drink tea when eating seafood. It is best to wait more than 2 hours apart.

1. Breeding environment.

Raise the pond water level. In view of the low water level of pond aquaculture and the poor water source of the outer river, the method of gradually adding pond water is adopted every three or five times, so that the pond water level is gradually raised to more than meters, and each time the water is added, it is selected to be carried out from 10 a.m. to 2 p.m. in fine weather.

Increase dissolved oxygen in the water body. If there is an aeration equipment, you can insist on turning on the aerator for more than 2 hours at noon on a sunny day, and in case of rainy days or sudden changes in weather, you should turn on the aerator in time. If there is no aerator, a submersible pump can be used to pump circulating water in the pool (the time is before 3 p.m., not in the evening) to enhance the convection and exchange of water.

Biological regulation of water quality. All kinds of aquaculture species have entered the first period of growth, but at the same time as the feeding is vigorous, their excrement has also increased significantly, which has accelerated the deterioration of water quality. Therefore, it is recommended to choose a biological agent made of a variety of microbial strains to spray, regulate the water quality, and use the specific dosage and precautions correctly according to the instructions.

Crabs should be fished and put into the shade of aquatic weeds to reduce direct sunlight and reduce water temperature, and if there is a lack of oxygen, the propeller of the hang-up boat can be used to push the water to increase oxygen and increase the flow of water.

2. Scientific feeding.

According to the nutritional needs of different breeding objects, feed with comprehensive nutrition, and avoid feeding moldy and inferior feed. It is advisable to control the amount of feed to be eaten within 2 hours to prevent the water quality from being spoiled by the residual bait. The fish feed fed in river crab farming should be kept fresh to prevent visceral diseases and water pollution.

3. Disease prevention.

Chlorine dioxide, dibromohydantoin, bleaching powder or quicklime and other drugs are used for regular disinfection of water bodies to prevent and control the occurrence of diseases. An appropriate amount of VC, immune polysaccharides or oral drugs can be added to the feed at intervals to enhance the disease resistance of the breeding objects.

If a disease is found, it should be diagnosed in time, and it should not be rushed to the doctor. When using drugs, we must follow the guidance of aquatic technicians, choose high-quality, high-efficiency, and low-toxicity drugs, and reduce the amount of drugs, so as to achieve reasonable application, and beware of drug accidents caused by overdose.

Eating contaminated or stale dead seafood may cause microbial poisoning, causing symptoms such as diarrhea and vomiting.

Distinguish whether it is fresh: the head and tail of fresh shrimp are complete, the head and tail are closely connected with the body, the shrimp body is relatively straight, with a certain elasticity and curvature, and the head and body, shell and meat are connected loosely, and the head and tail are easy to fall off or separate, and can not maintain their original curvature; Fresh shrimp have a normal fishy smell, if there is a foul smell, it means that the shrimp have gone bad.

Eating seafood is contraindicated.

1. Seafood should not be beer;

2. Patients with arthritis eat less seafood;

3. Avoid eating seafood with fruits that contain more tannins, such as grapes, pomegranates, hawthorns, green fruits, etc.;

4. Shrimp cannot be eaten with vitamin C;

5. After eating seafood, do not eat cold drinks, watermelon and other foods within an hour, and do not go swimming immediately.

6. Beware of mercury poisoning when eating marine fish. The mercury content of many marine fish is high, especially carnivorous marine fish, such as tuna, sea bass, cod, big bizh, flag negative, shark, black spotted cod, etc.
