Can crabs be domesticated? How do you keep crabs at home?

1. You need to find a larger plate or goldfish bowl, and then add a certain amount of sediment to the plate or fish bowl. It's best to pile up like a small slope. Then add a little bit of salt water, but no more than half of the sediment. If possible, it's better to put some aquatic plants or something.

2. You need to loosen the crab, and then without tongs, the crab cannot eat.

3. Crabs like to eat shellfish products, so they can sprinkle some small snails or clams (live) on top of the sediment. And crabs are nocturnal foraging animals, so they need to be fed at night. In the morning, crabs like to burrow into the mud and sand to rest.

4. The life of crabs is most suitable in a humid environment of 18 -25. So it needs to be placed in a ventilated and cool place.

After all, unlike other fish or turtles, blue crabs generally survive for about seven to ten days in an unnatural seawater environment.

It can be domesticated, and many of the crabs we eat now are rice crabs and cage cages.

If you're going to be a pet, just change the water every day and feed it regularly. If you're going to start a farm, you have to have some experience.

You can raise it in a basin, it doesn't matter if the water is deep or shallow, it won't drown it. However, it is better to have water freshly soaked in the shell. You can let it bask in the sun, don't bask it for too long. You can use tap water for water, but you don't need to use it until you dry it for a day.

Crabs are omnivorous.

You can feed them fish, whether it's raw or dried. They may also be fed fish feed, bloodworms, dried shrimp, snails, mussels. It is best to feed some grass-based foods frequently, such as bitter grass, eloso, etc.

As long as the feeding is OK, there is no need to worry about the rest. Crabs are easy to raise.

To add salt, add 1 liter to 2 level tablespoons of salt.

Don't tie it, you can't put too much water in raising crabs, just submerge its belly, but be careful that the water is easy to freeze in winter, in addition, you can throw a little leftover rice! Okay, let's give points, dear, I hope it can help you!

Domesticated crabs, regular water changes, appropriate amount of bait, sufficient light, good escape prevention, shelling and feeding. Erli River Crab Breeding Base provides.

Develop a farm and you're ready to feed.

Put the crabs in a cage and raise them in clean river water.

It can be farmed in unpolluted rivers.

Dig a pond and raise it in the pond.

If you can't feed it, what kind of sea spirit does that thing want, a few crabs, it's not worth it. Wild, generally unrasched.

If the number of crabs is not too large, you can prepare a plastic bucket with a depth of more than 30 cm, and the inner wall of the bucket should be relatively smooth, which can prevent the crabs from crawling out and escaping. The crabs you bought must not be washed, they are easy to die when washed, just put the crabs in the prepared plastic bucket, the most important thing is not to let the crabs layer up, that is to say, only one layer of crabs can be placed.

After the crab is placed, add clean water, and the amount of water should reach just half the height of the crab's body, so that the crab's eight legs can be exposed to the surface of the water to breathe. The main function of this water is to moisturize the crabs, and adding too much water will cause the crabs to lack oxygen and suffocate to death.

After adding water, put the bucket in a cool and ventilated place indoors (you can't put the bucket in the sun, if necessary, you can use breathable gauze or cotton cloth to shade the light), do not cover, and change it with clean water once a day.

Temporary crab breeding in this method is simple and practical, and when the temperature is not too high, it can even be stored for more than 5 days (the indoor temperature does not exceed 15), and the crabs will not die. If the number of crabs is larger, you can use a larger plastic basin, or directly use the family bathtub, the specific operation is exactly the same as above.

Raising crabs temporarily in this way has no fattening effect, and raising them for too long will make the crabs slowly emaciated, but eating them within 3 days will not affect the taste. If you want the crabs to get fatter and fatter for a longer period of time, you can feed the crabs every day on the basis of the above practices.

The method of feeding the crab is very simple, according to the number of crabs, take an appropriate amount of eggs and break them into the container of raising crabs, then sprinkle some rice, and then sprinkle some black sesame seeds. There is an easier way to feed the crabs, which is to buy some small fish and shrimp and put them directly in the container, and the crabs will eat these small fish and shrimp when they are hungry.

Crabs fed feed can survive for more than 7 days or more, and better quality crabs can achieve a survival rate of more than 95%.

There is an easier way to keep crabs for a short period of time, which is to bundle the crabs and put them in the refrigerator (preferably the layer where the fruit is placed), and then spread the wet towel on top of the crab, do not wring it too dry, and do not fold the towel up, so that the crab will not die for about 3 days.

Reminder: 1. The hypochlorous acid in the tap water will definitely be harmful to crabs, so it is best to put the tap water used to raise crabs for a period of time in advance, so that hypochlorous acid can become chlorine gas and volatilize before being used to raise crabs, and the effect is better.

2. If the crab you are going to raise temporarily is a sea crab, you must add an appropriate amount of salt to the tap water, and the saltiness should be slightly salty.

1. It is best to use a lid for the fish tank to prevent the crabs from escaping. Plant a aquatic weed, put some small stones and sand, and more realistically simulate the wild living environment of crabs. Crabs are also burrowing animals, so it's best to pick up a tile, wash it and put it in a fish tank and let it live in it.

Crabs should also bask in the sun, but not for too long. 2. Feed crabs bread crumbs, potato crumbs, steamed bread crumbs, rice, snails, small fish and shrimp and other foods. 3. Change the water once a week, it is best to use natural living water [river water, lake water], and use tap water for two days if you don't have it.

The water should be over the back 4, the shell of the crab is yellow when it is shelled, and the body is soft after the shelling, so it should be raised separately from other crabs to avoid cannibalism. And feed more meat foods, such as small fish and shrimp. If successful, they will give you a lot of fun.
