How to raise small crabs (with pictures)

To raise small crabs at home, you need to prepare a container, such as a plastic basin, fish tank, etc. It is recommended that the breeder place stones and sand at the bottom of the basin to simulate the wild environment; food, crabs are omnivores, breeders can feed them egg yolks, small fish and shrimps or vegetables; cleanliness, it is recommended to change the water every three days while raising crabs.

Before raising crabs at home, breeders need to prepare a container such as a plastic basin, a glass fish tank, etc., and spread sand in the water, sprinkle some stone heads, branches, etc. to simulate the living environment in the wild and make the crabs live better. Crabs are omnivorous animals and also eat carrion. Breeders can prepare some egg yolks, small fish, shrimps or vegetables such as cabbage leaves for them to feed. Crabs are almost not picky eaters, and breeders only need to feed them twice a day. In the process of raising crabs, it is recommended that breeders change the water in the fish tank every three days and add some lime powder to the water to sterilize it. In addition, it is necessary to regularly take out the crabs and use a brush to clean their bodies, which can effectively prevent the crabs from getting sick.

Crabs are not like other small pets. They need special methods to be raised. As long as you pay attention to every detail, you can raise crabs well.

It is not suitable to raise crabs in such a small box. Find a fish tank or a large glass canning jar, fill it with about 1/3 soil (clay is best, ordinary soil is also fine, if there is no soil, use sand + small stones. Crabs like to dig holes to hide themselves), and then add a small amount of water. Don't add too much water to submerge the crab in water, otherwise it will not be able to breathe and will die.

It is doubtful whether crabs can eat mountain rice. In the wild, crabs cannot eat rice. Besides, if you leave too much rice for a long time, it will go bad and pollute the water. You should not feed too much rice. Ten grains of rice is enough for three crabs at a time. Anyway, when I raised them before, I fed them lettuce leaves...

If it is a hairy crab, that is, a freshwater crab. Minced meat, put clay above the water level in the fish tank, and feed it with earthworms. It cannot reproduce in the fish tank. Put water at one end and put food on the clay. Put it in the fish tank

If it is a hairy crab, that is, a freshwater crab, put it in a fish tank. Put clay above the water surface at one end of the fish tank and water at the other end. Put food on the clay. Minced meat and earthworms cut into small pieces and feed them. They cannot reproduce in the fish tank.

I suggest you give it turtle food or fish food.

How to raise crabs???

Prepare plastic buckets, water, and feed. When the weather is cold, you can keep the crabs indoors. The specific steps are as follows:

1. Put the crabs in a plastic bucket. If there are a lot of crabs, put them in a larger container. It is best to make it transparent so that you can observe the condition of the crabs.

2. Add water to half of the crab's body. In order to keep the water fresh, change and add water frequently to keep the pool water clear, refreshing and alive.

3. Then add some feed. The bait should be mainly high-quality granular feed, fresh ice fish and soybeans.

4. This way it can be stored for a period of time.

River crabs hide during the day and come out at night. They like clean water with high dissolved oxygen, are afraid of strong light, and love quietness. They start to feed when the water temperature is above 10℃, and shed their shells and grow at around 15℃. The growth period is 20-28℃, so the pond structure should be suitable for their habits.

Area and water depth: Generally 2 to 5 mu is appropriate, and the water depth is usually maintained at about 1 meter.

The pond slope is 1:2.5, and crab holes are set up on the slope, accounting for about 20% to 25% of the area; a "dark island" should be built in the pond for crabs to dig holes, eat and molt.

Water quality. The water quality should not be too rich, and the transparency should be maintained at 30 to 50 cm. Too rich water is prone to lack of oxygen, which can cause death in severe cases. The water source is preferably river water.

Additional information:

If you have a fish tank at home, you can use it to raise it. If not, you can also use a basin. It doesn't matter if the water is deeper or shallower when raising it in a basin, it won't drown it. But it's best if the water just covers the shell. The above is right, you can use sand to create a natural environment for it so that it can climb up.

You can feed them fish, whether raw or dried, they can accept it. You can also feed them fish feed, such as red worms, shrimps, snails, and mussel meat. It is best to feed them some grass food regularly, such as bitter grass and elodea.

Hello, everyone, I am Mianyanmayu, and I will share different exciting information with you every day.

Today we are going to discuss how to best raise crabs since the crab market is extremely profitable.

Let me explain this matter in detail below.

Crab breeding pond

If you want to do a good job in the mixed breeding model of lobsters and crabs and obtain higher economic benefits, you also need to pay attention to the following points:

1. Do a good job in the basic construction of breeding ponds in the early stage;

The width of the pond stem should be kept at about 3-4 meters, the slope of the pond stem should be about 1:3, and the water storage depth of the breeding pond should reach more than 1.2 meters. A "U"-shaped ditch should be dug in the breeding pond, with a depth of about 1.2-1.5 meters, a width of 4-5 meters, and a slope of about 1:2.5. Finally, a drainage system and escape prevention and theft prevention facilities should be built.

2. Aquatic plant maintenance;

Water plants are an important factor in the success of shrimp and crab farming. The main type of water plants is Elodea. If conditions permit, you can plant Hydrilla verticillata, Vallisneria, etc. to enrich the ecological environment of the breeding pond. Since water plants can be used as part of the bait for shrimp and crabs, it is necessary to ensure that the water plant coverage area accounts for more than 50% of the entire pond area, so that the impact of crabs and crayfish on each other can be minimized. Because crayfish and crabs need to shed their shells, they need to rely on water plants to avoid natural enemies. In addition, the breeding pond is prone to hypoxia during the summer thunderstorm season, and water plants can help crayfish and crabs float to the surface to breathe. At the same time, abundant water plants can also purify and regulate water quality. Therefore, the planting and management of water plants are particularly important for the success of breeding.

3. Water quality management;

Avoid using any polluted water, change water regularly, and pay attention to regulating water quality. You can use some basal fertilizer appropriately to cultivate small zooplankton for crayfish to eat. Ensure that the water quality is "live, tender, clear, and refreshing". For crab farming, 1,000 to 1,500 crab seedlings per acre should be released around February; crab fishing can start around October and continue until the end of the fishing season.

1. Pond

To raise crabs, you first need a pond, lake, or rice field. Crabs prefer clear water, so before you start raising them, you can clean the pond and remove the silt at the bottom. The depth should not exceed ten centimeters.

Then build a few places above the water surface in the pond, so that at night they can climb out of the water and do some appropriate activities to celebrate.

Then use quicklime for disinfection, which can kill bacteria and increase the calcium ion content in the water. It will take at least half a month after disinfection before you can put the seedlings in. For example, if there are tadpole eggs or other eggs in the water, they must be cleaned up.

2. Breeding aquatic plants

It is also very important to cultivate water plants in the pond, which can provide some plant bait for crabs, and the vitamin content in it is also relatively high. In addition, it can also increase the dissolved oxygen content in the pond. When it comes to water plants, pay attention to seasonality and have a certain connection. If the water plants are directly transplanted, they must be disinfected.

3. Prevent Escape

Crabs do not live entirely in water. Sometimes they will crawl out. So whether they are raised in ponds or lakes, you must take some measures to prevent them from escaping.

4. Planting Seedlings

When choosing seedlings, you should pay attention to choosing those that are healthier. You should check whether their feet are complete and free of damage, and it is best if they come from the same company.

After selecting them, do not put them in the water immediately. You must let them get used to it slowly. You can let them stay in the water for a few minutes, and then take them out. After adapting a few times, they will get used to it. In this way, the survival rate will be higher.
