How can the crab not die?

The fresh and tender meat of river crab, rich in nutrition, is deeply loved by people. Many people will buy a lot of river crabs in the season of eating river crabs and eat them slowly at home. So why can't the river crabs die?

First, why can't river crabs die?

1. To raise at home, use a basin to raise, the basin can put some fine sand to form a small platform. The water raised should not be too deep, the best water depth is that the steel is immersed in the shell of the crab, and the water raised can be used with tap water, but it can only be used in the sun for a day.

two。 Crabs are omnivores. If possible, you can feed red nematodes, you can feed egg yolk, of course, crabs can also eat chicken and duck offal or small fish and shrimp. At the same time, we should feed some grass food. You should pay attention to the amount of food, and eat it within half an hour, otherwise the rest of the food will pollute the water.

3. The feeding intensity of crabs increases or decreases with the change of season and water temperature. When the water temperature rises above 15 ℃ in summer and autumn, the feeding ability of crabs increases, and the crabs are fed once a day. When the water temperature drops below 15 ℃, the feeding ability of crabs decreases and can be fed every other day or several days. The appropriate time for feeding is around evening, because crabs are aquatic animals that lie dormant during the day and come out at night.

2. Taboos on the consumption of river crabs

1. Be sure to heat the crab thoroughly when cooking, otherwise it can easily lead to acute gastroenteritis or food poisoning.

two。 Patients with colds, fever, chronic gastritis, gastric and duodenal ulcers, hyperlipidemia, coronary heart disease, rheumatoid arthritis, dysmenorrhea and pregnant women are not suitable for consumption.
