After the beginning of autumn, it is the crab season , what details should be paid attention to whi

First of all, don't eat raw crabs and dead crabs, and secondly, you should eat them freshly steamed, and don't eat too much at the same time, and then there are some patients with diseases who can't eat them, and don't eat them with tea and persimmons.

River (lake) crabs feed on animal carcasses or humus, so the body surface, gills and gastrointestinal tract of crabs are covered with all kinds of bacteria and sludge. Some people will eat the germs or parasites in the crab because they have not washed the crab clean, cannot be steamed thoroughly, or because they eat drunk crabs or pickled crabs rawSo be sure to steam and cook thoroughly before eating, there will be no problem.

The stiffness period and autolysis period of river crabs after death are greatly shortened, and the bacteria in the crab will multiply rapidly and spread to the crab meat, causing vomiting, abdominal pain and diarrhea to eaters. If you can't finish eating, the rest must be kept in a clean, cool and ventilated place, and you must return to the pot and cook and steam thoroughly when eating.

Crab meat is cold, and those with spleen and stomach deficiency should pay special attention to avoid causing abdominal pain and diarrhea. Patients suffering from colds, fevers, stomach pains, and diarrhoea. People with chronic gastritis, duodenal ulcer, cholecystitis, gallstones, hepatitis active.

When the crab is fat, the persimmon is also ripe, and you should be careful not to eat these two things at the same time. Because the tannic acid and other components in persimmon will coagulate the crab meat protein, the coagulated substances will ferment and rot if they remain in the intestine for a long time, causing vomiting, abdominal pain, diarrhea and other reactions, and may also cause stone disease.

Do not drink tea during or within 1 hour after eating crabs. Because boiling water will dilute stomach acid, tea will make some components of crab coagulate, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.

You must choose healthy crabs to eat, never eat some dead crabs, so we have to carefully observe one by one when choosing, if you find that the crabs are half dead, then you can't buy them.

The Mid-Autumn Festival is the best time to eat crabs, think about it, but the ** of high-quality hairy crabs is not low, and it is a good choice to eat crabs to improve your life, but as everyone's living standards are getting higher and higher, the pursuit of quality is getting higher and higher. Pond crab farming is a new development of aquaculture, with an average yield of 100 kg per mu and a high yield of 300 kg, with very high economic benefits. How to raise a good freshwater crab?

The breeding technology of freshwater crabs is detailed below. The suitable water temperature for crabs is around 20. When the water temperature is at a lower level, the amount of movement of the crab decreases, which affects the amount of food consumed by the crab, which makes the amount of food consumed by the crab decrease.

If the water temperature is high, it will promote the activity of the crabs, so that the amount of exercise of the crabs will increase, and the intake will also increase. In the spring or during the crab life, the water depth is controlled at about 1 meter, in the summer it is meters, and in the autumn it is meters. Hot temperatures increase the depth of the water and lower the bottom temperature.

Water quality control water visible transparency is generally 50-60 cm. The water is too clear or too muddy, and the physical and chemical properties of the water have an impact on the growth of crabs. Before feeding, the excess silt in the pond should be removed, and then the pond should be dried and evenly sprinkled in the pond with quicklime.

According to their own conditions, try to choose excellent water sources, plant aquatic plants reasonably, and feed crab seedlings after the water body is stable. The feeding density should be reasonable to avoid excessive density and turbidity caused by grabbing food. Choose high-quality feed to promote the absorption and utilization of nutrients by river crabs, reduce the pollution of feed to water quality, and reduce the amount of harmful substances in the water.

Check the pH of your water regularly to see how your water is changing.

In the pond, if blue-green algae appear, control it in time, or replace the pool water, and when the organic matter content in the water exceeds the standard, it is necessary to increase the water change or water change. In summer, it is necessary to prevent the overgrowth of aquatic plants and algae, and the excess aquatic plants in the crab pond should be removed in time to control the overgrowth of phytoplankton.

As the old saying goes, "the size of the crab depends on the aquatic weeds, and the number of crabs depends on the aquatic weeds", which shows the importance of aquatic plants in the process of river crab breeding. It can not only provide a shelter (perch, molt and avoid predators) for river crabs, but also can purify water quality by releasing oxygen in the water, consuming excess nutrients in the water, inhibiting the growth of single-celled algae, and effectively reducing the accumulated temperature and providing shade for river crabs during high temperature periods. Aquatic weeds are also bioactive baits that river crabs like to eat.

The distribution of aquatic weeds in the crab pond should be sparse and dense, and the aquatic weed coverage rate should be kept at 60% 70% during the growth period of river crabs. Once the above situation occurs, the cause should be found out in time and used reasonably"Youcaoling".In order to improve the condition of aquatic weeds, Youcaolin has played an active role in river crab breeding in many places.

The pond should maintain a high water level, the pond should be often added and changed water, generally required to add water once in 2-3 days, change the water once in 5-7 days, choose to enter the water in the morning or evening, should not add water at noon, in order to prevent the temperature is too high to hurt the crab body. It may be due to multiple factors such as poor water quality regulation and inadequate sterilization and disinfection, which may lead to stressful phenomena such as crawling and lying on the grass, which may even lead to death in severe cases. In response to this situation, many farmers will use it"Eugen".Complex toxin, anti-stress, it can complex a variety of toxins in the water body, inhibit the generation of ammonia nitrogen, nitrite and other harmful substances, increase the dissolved oxygen in the water body, and repair the bad water body; In addition, it is rich in nutrients such as small peptides, which can also reduce the stress damage of river crabs caused by changes in the external environment.

It is recommended to control the amount of feed in 7-8% of the pond volume, and if the body fat content of the crab is too high, it is not conducive to the molting of river crabs, the proportion of animal and plant bait should be appropriately adjusted, and the proportion of plant bait (such as wheat, corn, aquatic weeds, etc.) should be higher than that of animal bait. For crab ponds fed with pellets, you may wish to consider mixing (dry mixing) in the feed"Staling".After use, the feeding speed of river crabs is significantly accelerated, the bottom quality is stable, the residual bait is less, and the water quality is easier to control in high temperature days. In addition, Staling also has beneficial effects such as protecting the liver and gallbladder and improving intestinal adaptability, and has been widely used in aquaculture in many places.

When breeding, we must choose a better variety, and then we should also feed some nutritious feed or small fish and shrimp in a timely manner, and we also need to clean up the pond regularly, to keep the pond water clean and hygienic, and also need to remove some weeds in the water to keep the oxygen in the water sufficient.

When breeding crabs, we must pay attention to the problem of water, and then we should also choose the right breeding area, to maintain the temperature in the water, we also need to ensure that the oxygen in the water is sufficient, and we must choose to feed some nutritious feed, so as to make the crabs more fat.

The water quality must be good, the water source must be sufficient, there must be convenient drainage, good air permeability must be ensured, and good varieties must be selected.
