Why do people die after being bitten by mosquitoes?

1. How to raise soft-shell turtles so they don’t die easily

1. Feed production: soft-shell turtle feed is mainly animal protein, supplemented by plant protein. Fresh feed includes small miscellaneous fish, animal offal and scraps. Green feed includes fresh aquatic plants, fruits, vegetable stems and leaves. Wheat bran, corn flour, bean dregs, etc. can also be mixed and processed before feeding.

2. Feeding bait: Soft-shelled turtles start eating when the water temperature rises to about 18°C. At this time, feed a small amount of bait for acclimation, so that the soft-shelled turtles start eating early. The daily feeding amount of fresh animal feed is 10-20% of the total weight of soft-shell turtles, and the daily feeding amount of compound feed is 5% of the total weight.

3. Feeding method: When feeding soft-shell turtles, adhere to the four fixed and four-viewing methods. Feeding is generally carried out in fixed food courts on both sides of the pond that are ventilated and sunny, which is conducive to observing the feeding and growth of soft-shell turtles and fish. and activity conditions to facilitate adjustment of feeding amount.

4. Water level management: Keep the water level at 80 to 100 centimeters in the early stages of soft-shell turtle stocking, and gradually increase the water level as the water temperature rises and the individuals grow. Add new water every half month in spring and autumn, add new water once a week in summer, and increase the water level during high temperature seasons in summer and early autumn.

5. Water quality management: Regularly sprinkle 15 to 20 grams of quicklime or 2 grams of bleaching powder per cubic meter in the turtle breeding tank to ensure that the dissolved oxygen in the water is above 4 mg/L and the pH value is 7 to 8.5. The ammonia nitrogen should not exceed 5 mg/L, and an aerator should be equipped if necessary.

6. Daily management: When raising turtles, you must patrol the pond twice a day, morning and evening, observe the activities, eating and growth of turtles and fish, and adjust the feeding amount in a timely manner. Remove the remaining bait and debris in the pond promptly to ensure fresh water quality.

2. Who should not eat soft-shelled turtles

1. In patients with hepatitis, their digestion and absorption functions are greatly weakened due to edema of the gastric mucosa, thickening and shortening of small intestinal villi, and imbalanced bile secretion. Turtle is rich in protein. Not only is it difficult for patients to absorb it after eating it, but it will increase the burden on the liver. In severe cases, liver cells will undergo massive necrosis, serum bilirubin will increase sharply, and plasma concentration will increase, inducing hepatic coma.

2. Insomnia, pregnant women and postpartum diarrhea are also not suitable for consumption. Although it has the effect of nourishing yin and replenishing the kidneys, soft-shelled turtle has a salty and cold taste, and has a strong effect on dredging blood channels and dispersing blood clots. Therefore, it has certain disadvantages in abortion, especially the abortion power of turtle shell is stronger than that of turtle meat. .

3. People with weak gastrointestinal function and indigestion should eat with caution. Especially patients suffering from gastroenteritis, gastric ulcer, cholecystitis and other digestive system diseases should not consume it. People with weak spleen and stomach should not eat too much, otherwise they will often become inattentive to food, feel full in the abdomen, and even cause diarrhea.

4. Young children should eat less soft-shelled turtles. Soft-shell turtle is a high-protein tonic. Children's spleen and stomach are delicate. When consumed, it may cause indigestion and increase the burden on the spleen and stomach, so eat less.

3. Why do soft-shell turtles die after being bitten by mosquitoes?

The living habits of soft-shell turtles can be summarized as three joys and three fears, that is, they like silence and are afraid of surprises, like the sun and fear wind, and like cleanliness and fear dirty. Turtles are sensitive to sounds in the surrounding environment. As long as there is a slight movement around them, turtles can quickly dive into the mud at the bottom of the water. In the natural environment, soft-shell turtles like to inhabit clean rivers, lakes, reservoirs, ponds and other waters. During the day when the waves are calm, they often lie on the sunny shore and bask in the sun (commonly known as basking on their backs), using the ultraviolet rays in the sun to kill the harmful substances on the body surface. Pathogenic bacteria, promote the healing of injured body surfaces, increase body temperature through basking on the back, and promote food digestion.

Turtles mainly breathe through their lungs, but when the water temperature drops below 15°C, the turtles dive into the mud at the bottom of the pond and begin hibernation, relying on auxiliary respiratory organs such as gill-like tissues in the throat to breathe.

Turtles are ferocious and aggressive by nature, and bullying among groups is common. When food is scarce, they will cannibalize their own species.

Soft-shell turtles have the habit of hibernating. The hibernation period of turtles in the Hangjiahu area is from mid-November to mid-April of the following year. Turtles are most afraid of mosquito bites. Once bitten by a mosquito, the bitten area will become ulcerated and difficult to heal, and they will die soon. Therefore, live turtles should be stored in water to prevent mosquitoes from taking advantage of them.

The animal that kills with one bite from a mosquito is an animal whose common name is turtle, and its scientific name is turtle, and its dialect is called soft-shell turtle. However, if the smooth soft shell of this animal is ground into powder, it can kill mosquitoes immediately after being lit.
