What is the reason for the shrimp head shell, the reason for the shrimp soft shell

Lack of available trace elements and effects in water bodies.

Shrimp are infected by harmful bacteria or viruses and die after shedding their shells.

Death from nitrite poisoning or drug abuse.

Summary. Hello dear!

Concern. The main components of shrimp carapace are moisture, protein, ash, chitin, etc. Among them, calcium is abundant, and studies have shown that among the main components of shrimp carapace, calcium is close to 20% of the dry weight of shrimp carapace.

Therefore, the demand for calcium in shrimp during the molting period is relatively large, therefore, the factors affecting the absorption and utilization of calcium in shrimp can lead to the occurrence of shrimp soft shell. In the process of farming, the causes of shrimp soft shell include the following aspects.

There are many factors that contribute to the development of soft shell, the main reasons are:

1.Long-term lack of bait makes the shrimp appear starving.

2.The nutrient ratio of the bait is unbalanced, and it is fed with low-grade bait. The nutrition of the bait is often not up to the mark.

3.Feed spoiled bait.

4.The content of dissolved phosphorus in the pond water decreased, and the phosphorus uptake of shrimp was insufficient, and phosphorus was the main factor in the calcification process of shrimp carapace.

5.The breeding density is too high, the breeding environment is poor, and the deterioration of water quality leads to the softening of the shell.

Therefore, the demand for calcium in shrimp during molting is relatively large, therefore, the factors affecting the absorption and utilization of calcium in shrimp can lead to the occurrence of shrimp soft shell. In the process of farming, the causes of shrimp soft shell include the following aspects. There are many factors that cause soft-shell potato finch disease, and the main reasons are: 1

Long-term lack of bait makes the shrimp appear starving. 2.The nutrient ratio of the bait is unbalanced, and it is fed with low-grade bait.

The nutrition of the bait is often not up to the mark. 3.Feed spoiled bait.

4.The decrease in the content of dissolved phosphorus in the pond water is a major factor in the calcification process of shrimp carapace. 5.

The breeding density is too high, the breeding environment is poor, and the deterioration of water quality leads to the softening of the shell.

6.The water contains an organic phosphorus cover fibrillation insecticide, which inhibits the synthesis of chitin in the shell of shrimp. 7.

Improper use of drugs or sudden changes in water quality cause shrimp to be irritated and abnormal shelling occurs, and it is difficult to return to normal state in a short time. Shrimp vertical shells become soft, often infected with diseases and outbreaks occur. In addition, when the shrimp is released, the soft-shell shrimp can easily die out of the water, resulting in a decrease in the survival rate of transportation.

Therefore, the proportion of soft shells should be reduced as much as possible during the breeding process.

<> the hardness of the aquaculture water is not enough, the water body lacks calcium, the ratio of calcium and phosphorus is unbalanced or the form of calcium in the Xianyan water body is not conducive to the absorption of Tuanpai potato shrimp, resulting in the lack of calcium during the molting period of the shrimp, thus causing the soft shell of the shrimp to collapse; The reason for the physique of the shrimp itself is that it is difficult to utilize the calcium in the water body, resulting in the soft shell of the shrimp; The increase in the pH value of the pool water and the decrease in the content of organic matter decrease the concentration of dissolved phosphorus in the water, forming insoluble calcium phosphate precipitates, and reducing the available phosphorus of the shrimp, resulting in the soft shell of the shrimp.

<> carry out water quality testing, and if the water quality indicators are poor, deal with the water quality problems first; Supplement the deficiency of mineral elements in the aquaculture water, especially calcium; Immune enhancers such as "Liver Transformation and Modification of Lingnucleus Jujube", "Ganning", "Gushu'an", "Compound Immune Polysaccharides" and "Stable VC" to repair the constitution are helpful for the recovery of prawn soft shell.

Soft shell is also one of the main diseases in the process of shrimp farming, which has a great impact on the growth of shrimp, and more shrimp will die in severe cases. There may be several causes of shrimp soft shells:

1) Long-term insufficient feeding or unreasonable feed formula makes the shrimp intake insufficient nutrients and starvation.

2) Phosphorus is the main element in the formation and calcification of shrimp carapace, when the content of dissolved phosphorus in the pond water is too low, the phosphorus uptake of shrimp is insufficient, that is, the soft shell.

3) The aquaculture water lacks an appropriate amount of calcium, which cannot meet the needs of normal molting of shrimp, especially in low-salinity aquaculture.

4) The breeding density is too high, resulting in a poor breeding environment, resulting in the deterioration of water quality, resulting in the softness of shrimp shells.

5) Especially in fresh water, nitrite has a greater effect on shrimp. When the content exceeds a certain concentration (varies from water to body, generally more than milligrams), it will lead to a soft shell of shrimp.

6) The concentration of organotin or organophosphorus insecticides in the pool water is too high, which inhibits the synthesis of chitin in the shell of shrimp.

1. Soft-shell dead shrimp on rainy days. The sudden change in water temperature after rain causes stress shedding of shrimp, so that the resistance decreases rapidly, and it is easy to produce soft shell or hard shell dead shrimp.

2. Shrimp toxin poisoning soft shell steals death. Toxin poisoning steals death, including organic toxins (mainly dead algae and organic putrefactive matter), ammonia nitrogen, nitrite and low dissolved oxygen at the bottom, etc., usually such dead shrimp have aged or turbid water color.

3. Low-temperature soft-shell dead shrimp and prevention. Low-temperature soft-shelled dead shrimp. The main reason is that the nutrients and trace elements absorbed by the shrimp are insufficient, and the water temperature is below 17 in the weather, when the shrimp are shelled, a large number of deaths often occur, especially in freshwater aquaculture ponds.

Strengthen feed nutrition, feed feed with high protein content, and add Youlanbao for mixing, enhance the immunity of shrimp to prevent the production of soft shell.

Summary. The shrimp heads of large red shrimp are empty because their shrimp heads are partially made of cartilage, and the cartilage is burned off by the heat during the cooking process, so when cooking is done, the shrimp heads will become hollow.

The shrimp heads of the big red shrimp are empty, and the reason for this is that the shrimp heads they serve are made up of cartilage, and the cartilage will be burned off by the heat during the cooking process, so the shrimp heads will become hollow after the cooking is completed.

Can you add, I don't quite understand it.

The head of the big red shrimp is carefully empty, probably because the meat inside the shrimp head is damaged or damaged, causing the meat inside the shrimp head to be extracted, so that the shrimp head becomes empty. Solution: 1

When buying red shrimp, you should carefully inspect the shrimp head to ensure that the meat book inside the shrimp head is intact, so as not to buy a damaged shrimp head. 2.If the shrimp head is already damaged, the shrimp head can be placed in warm water to allow the flesh inside the shrimp head to swell, so that the shrimp head becomes whole.

Personal Tips:1When buying large red shrimp, you should carefully inspect the shrimp head to make sure that the meat inside the shrimp head is intact to avoid buying damaged shrimp heads.

2.If the shrimp head is already damaged, the shrimp head can be placed in warm water to allow the flesh inside the shrimp head to swell, so that the shrimp head becomes whole. 3.

When cooking large red shrimp, care should be taken to control the cooking time so that the meat inside the shrimp head is not overcooked, which will cause the shrimp head to become empty.
