How to Keep River Crabs Alive: Farming Methods to Improve the Survival Rate

River crab flesh is tender and nutritious, and is deeply loved by people. Many people, during river crab season, buy many river crabs and keep them at home to eat slowly. So how do you keep river crabs alive?

1. How to Keep River Crabs Alive?

1. To keep them at home, use a basin, and you can put some fine sand in the basin to form a small platform. The rearing water must not be too deep; the best water depth is water just covering the crab's shell, and the rearing water can be tap water, but it must be left in the sun for one day before use.

2. Crabs are omnivorous animals. If conditions permit, you can feed them bloodworms, or feed them egg yolk; of course, crabs can also eat the internal organs of chickens and ducks or small fish and shrimp. At the same time, feed them some grass-type food. Pay attention to the feeding amount, taking finishing within half an hour as the standard, otherwise the leftover food will pollute the rearing water.

3. The feeding intensity of crabs increases or decreases with changes in season and water temperature. In summer and autumn, when the water temperature rises above 15°C, the crab's feeding ability increases, and at this time feed once a day. When the water temperature drops below 15°C, the crab's feeding ability decreases, and you can feed once every other day or every few days. The feeding time is best around evening, because crabs are aquatic animals that rest by day and come out at night.

2. Dietary Taboos for River Crabs

1. When cooking river crabs, they must be thoroughly heated, otherwise it can easily cause acute gastroenteritis or food poisoning.

2. People suffering from colds, fever, chronic gastritis, gastric and duodenal ulcers, hyperlipidemia, coronary heart disease, rheumatic arthritis, menstrual cramps and other conditions, as well as pregnant women, should not eat them.

3. Crabs cannot be eaten together with foods such as tea, peanuts and potatoes, otherwise it will produce toxic substances, diarrhea, stones and other consequences.

Crabs should not be kept at home for too long; river crabs bought back are best eaten within 3 days. If kept too long, the river crabs may not be fresh and the flesh will become tough.
