How to raise wild small crabs How to raise wild crabs

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. When the crab is shelled, the shell is yellow, 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.

First depends on how many you want to raise, and then decide how big the utensils to use to hold it, I usually use small pots to hold it, crabs, of course I like to eat meat, but you feed it cooked meat (because I don't know how big you raise), you can also put some small fry, but now it's almost winter, only need to give it a small amount of water is enough, more water will be cold to death. Pour hot water in another clean basin every week, then add cold water, feel the temperature of the water with your hands, just a little bit of heat, buy a small net, fish them out one by one, put them in, they will crawl quickly and lively, let them play for a while, and then put them back, before putting them back, wash the original basin Oh, (put the food in for up to 3 hours must change the water, otherwise it will pollute the water quality and cause them to die.) Feeding them once a week is fine, and it's best to feed them on the day they are allowed to roam freely!

I just talked about the winter cultivation method, and now it is summer: there should be more water, half of the container is enough, if there is some water, and small stones are put so that they can hide, and the pot is placed in a sunny place, and the summer is spent like this! Also, you generally don't eat in winter.

When feeding, you must pay attention to the density of the breeding, otherwise you will find that they are decreasing day by day. You must not touch it when it molts, this is its most fragile, it will die when touched, after molting the shell, you have to take it out with the gentlest movements and raise it alone for a few days, and then put it back when its new shell becomes hard. It can eat anything, but the ideal is meat, but you must pay attention to the water quality, steamed bread it also eats, and it is not bad to feed some cooked pork, it is best to bite it and then feed it. (ENDS).

If it is wild, it mainly eats some planktonic animals and plants, and if you raise it yourself, you can feed it some aquatic plants or dried fish and insects. Crabs love sandy environments, don't forget to put more sand.

The brook crab should not be soaked in the water for a long time, otherwise it will drown, and there should be a place where it can rise above the surface of the water and let it breathe. You can feed him a little fish and change the water once a day.

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 survival of crabs and destroy the environment. Crabs are 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 every day, but not for too long.

2. Feed the crabs bread crumbs, potato crumbs, steamed bread crumbs, rice, snails, small fish, shrimp and other foods.

3. Change the water once a week, it is best to use river water, lake water, or tap water that is used to prepare for the sky in the sun.

4. When the crab is shelled, the shell is yellow, and the body is soft after the shelling, so it should be raised separately from other crabs to avoid cannibalism, and it is necessary to feed more meat food, such as small fish and shrimp.

The steps are as follows:

The first or shed, for which to prepare a shirt to respect a life tank, the water level in the tank is moderate;

Clause. Second, the breeding position is in an environment that can be exposed to the sun;

Clause. 3. Feed them some meat in rations.

Small crabs are not like other ordinary small pets, and they should be bred in a special way. As long as you do every detail well, you can raise the little crab well.

Here are a few important points to note:

First of all, it is best to provide a living environment for small crabs in a fish tank, the water level is not too high or too low, just over the crab's shell. You can also put some stones in the tank to simulate the original living environment of crabs.

Secondly, small crabs like to bask in the sun under natural conditions, so they should also model the living environment of small crabs in normal times, give them sun, and let them grow and develop better.

Finally, you can give the crab some meat from time to time, such as some small minced fish, shrimp meat, etc.

Crabs:

90% of crabs are seafood, and the rest are freshwater. Among marine crabs, such as sheep crabs, guangong crabs, frog crabs (ranina), and mantou crabs (calappa), they live in the subtidal zone at different depths.

For example, pike crabs live in shallow seas; Square crabs (grapsidae), sand crabs (ocypodidae) and most fan crabs (xanthidae) live mainly in the broad intertidal zone; A very small number of species, such as planes and varuna, can attach to wood or other floating objects that live in the ocean.

The details are as follows.

1. Breeding environment: Breeding crabs should use glass tanks as utensils and spread fine sand to the bottom. 2. Feeding method:

Do not feed the crabs in the early stage of farming, and wait for the crabs to adapt to the environment before they can be provided. 3. Clean regularly: Wash the back of the crab with a toothbrush and soap.

Crab (scientific name: crab) is a crustacean of the suborder Decapoda Brachytail, especially the species of the Brachytail family (true crab). Other types are also included, such as the crooked tail family, which has about 4,700 species.

It is found in all oceans, rivers and land. Unlike other decapods (e.g., shrimp, lobster, crayfish), the tail of crabs is curled under the thorax and the back is usually broad. The first pair of thoracic feet specialized as chelicera.

It usually moves in a walking or crawling manner. The horizontal gait of the common crab is familiar to people and is characteristic of most crabs. Species of the pike crab family and some other types swim with flat paddle-like appendages, dexterous movements, and powerful large pincers.

China's crab resources are abundant, among which the hairy crabs produced by Taihu Lake hairy crabs, Gaoyou Lake hairy crabs and Yangcheng Lake hairy crabs in the lower reaches of the Yangtze River are the top grades.
