How many days do crabs grow?

It is much cheaper to buy your own crabs and cook them, especially when you buy more crabs when they are cheap. Sometimes if you buy too many crabs, you plan to keep them for a few days before eating them. So, how do you keep crabs for a few days?

1. Container

Crabs can be raised in a deep basin. If there are too many crabs to fit in one basin, they can be scattered and raised. Don't let the crabs inside be too crowded, let alone layer upon layer. If you are worried that the crab will escape, the basin can be covered with gauze.

2. Water injection

The water can use the tap water at home, first let it soften for a few hours, and then pour it into the basin. If it is a river crab, it can be raised in clean water; if it is a sea crab, put some salt in the water. The depth of the water should not be as deep as the crab, but the crab's shell should be submerged so that its head can be exposed when it stands up, otherwise it will be difficult to breathe.

3. Placement

Put the basin in a cool and ventilated place indoors, not in the sun, do not cover it, and change it with clean water once a day. Using this method to temporarily raise crabs is simple and practical, it can even be preserved for more than 5 days when the temperature is not too high, but it has no fattening effect.

4. Feeding

If you want to eat it after a day or two, you don't have to feed it; if you want to keep it longer and don't let the crab lose weight, you can feed the crab some food, such as eggs, rice, black sesame seeds, shrimp, fish and so on.
