How do you keep crabs in your own house so that you don't die? Do you want to release the water or not?

Crabs have always been the main push category in major seafood markets, especially in autumn, when the crab roe is full of oil and the taste is memorable. But the crab market prices outside are relatively expensive, often tens of yuan per jin, many people say that eating meat pain! So how do you raise crabs if you want to raise crabs in your own home?

First, do you want to put water in raising crabs at home?

With regard to whether you want to put water in raising crabs at home, the key depends on the purpose of raising crabs.

1. The crabs bought in the market will be eaten in a short time.

The term "short-term" here generally refers to within three days. If this is the case, I believe that when buying crabs, the salesperson will also tell you that it is best not to put the crabs in the water, and will suggest putting the crabs in a slightly damp bucket and covering them with a wet towel.

If you throw the crab directly into the water, it will cause the crab to die due to insufficient dissolved oxygen.

2. Crabs bought in the market will not be eaten in the short term.

If it will not be eaten in a short period of time, then it is still recommended that you still need to raise it with clear water, but you should not have too much water, just past the back of the crab. In addition, you can also spread a layer of fine sand at the bottom of the container for raising crabs.

Second, how to raise crabs in your own home so as not to die?

Raising crabs at home can not only start with young crabs, but also raise mature crabs directly. The specific operation methods are as follows:

1. Breeding environment

Raising crabs at home can choose a pool that is more spacious and has a certain depth to prevent crabs from escaping. It can be a cement pond or a larger plastic basin.

Spread a layer of about 10 centimeters of silt and 5 centimeters of river sand in the crab pond. You can go to the riverside or lake to get some sand or buy it online.

If you plan to keep crabs at home for a long time, you can also plant some aquatic plants that are easy to survive in the pond, such as verticillium verticillata, Sophora flavescens, Elodea, which can not only purify the water quality, but also can be used as bait for crabs to eat.

Specific planting of several aquatic plants depends on the size of the breeding site and the number of crabs.

2. Crab specification

It is recommended that the specifications of crabs raised in the same pool should not be too different, so as not to affect the survival rate of crabs.

In addition, it is necessary to ensure that the raised crabs are disease-free and injury-free.

3. Feeding and management

(1) bait

In the process of feeding, you can feed red worms, shrimp, snail, clam meat and other animal bait, supplemented with aquatic plants, pumpkins, potatoes and other plant bait, feeding once in the morning and evening, the crabs will grow better.

(2) changing water

On the issue of changing water, it is suggested that the water should be changed every 3 days. After changing the water, it can be poured with appropriate amount of quicklime to sterilize and disinfect in time.

In short, although it is convenient to raise crabs at home, it is necessary to put some thought into the breeding environment in order to fatten the crabs.
