How to raise small crabs?
The water just reaches your mouth, so you can't exceed it. The turtle food I fed was packaged in yellow, and it was only for amphibians (small package). According to the size of the small crab, it is enough to put one in yours. I just put it in front of the crab's mouth and ate it later. If the water is dirty, it should be changed, including the smelly water. Don't expose yourself to the sun, it's not good for crabs. If you really expose yourself to the sun, prepare chopsticks and rice bowls. If the crab shell changes color and doesn't eat, don't worry, it should be shelled, just like mine. Keep it alone after shelling, so don't feed it first, because it's soft after shelling and it's all meat. When the shell is hard, feed it again. Every time you take off the shell, your body size will increase. It is impossible to know exactly when to shell. If you can, you can also put some pebbles, but remember to wash the pebbles and wash them when changing water. When shelling, you must keep it alone, otherwise it will be like a crab in my family, and it is very normal for a pair of pliers to be shelled by another ruthless KO. It's summer now, and many homes can't live without air conditioning. If you want to put air conditioning, crabs should stay away. There is more space in the basin and more places to move.
How to raise small crabs
I come from the countryside, and from my experience, you can feed some chicken and duck viscera and other things to crabs, but chop them up, and frog meat can also be used. Feed it in water.
For its life, you can pile some stones in the water and raise some live aquatic plants. The water should not be too cold.
How to feed small crabs?
Find a washbasin, and pour 2 cm high water into the basin, where crabs can just show their heads, preferably sun-dried water with oxygen.
One side of the washbasin is made of earth, and some crabs are burrowing, so they may dig holes, so the washbasin is better to be deep to prevent them from climbing out along that mound. Then eat just like upstairs, just throw some cooked rice. Don't throw too much food. If you can't finish it, you have to change the water if it stinks in the water. If you change the water frequently, the crab will die soon.
Some pet shops also sell crab food.
How to raise crabs?
Crabs grow shells in July and August and gain weight in September. In the high temperature season in summer, the activity of river crabs is frequent and their appetite is greatly increased, which is a critical period for the growth of river crabs, and management must be strengthened.
Create an ecological shelling environment: The crab will shell for the most critical time from July to August, which takes a long time and often leads to death due to unsuccessful shelling. Aquatic plants are the favorite plant feed for river crabs, and can also provide hidden places and substrates for them to remove organisms. Therefore, aquatic plants such as Elodea nuttallii, Alternanthera philoxeroides, Sophora alopecuroides and Hydrilla verticillata should be transplanted as soon as possible in the crab culture pond, and the coverage rate is about 50%, so that it can provide a cool habitat for river crabs, which is conducive to avoiding enemies when they shell and preventing soft-shelled crabs from being attacked by other crabs. If possible, pick out the soft-shelled crabs and put them in a ventilated, cool pond or basin with aquatic plants for temporary breeding, and then put them in the pond after the crab shells are hard, so as to improve the survival rate of shelled crabs.
Reasonably increase the feeding amount: In addition to adequate plant feeds such as water peanuts, water hyacinth and Sudan grass, feed animal feeds, such as offal from slaughterhouses, small miscellaneous fish, earthworms, snails and mussels, 2-3 times a week, or increase plant feeds rich in protein and fat, such as corn, small families and soybeans. The powdery feed is best mixed and steamed into blocks for feeding. The feeding amount is10% ~15% of the crab's weight in the pond, and it will increase or decrease according to whether there is any food left in the next day. Feed is put in the shallow water near the pool and fed at 3~5 pm every day to adapt to the habit of river crabs foraging at night and night.
Avoid water pollution: in the prosperous period of river crabs, it is necessary to ensure that the pond water depth is about 1 m, preferably clear, clean and rich in dissolved oxygen. Change the water regularly, every 3~4 days, and change the water every time 10~30 cm. It is best to change water before evening, and the water source should be clean, non-toxic and pollution-free. It was found that most of the crabs in the pond landed and spat, especially during the day, a large number of crabs climbed out of the water, and they were frightened and did not go into the water or landed immediately after entering the water, indicating that the water was short of oxygen or the water quality was deteriorated, so the water should be changed as soon as possible and the amount of water changed should be increased.
Timely prevention and treatment of diseases: In high temperature season, river crabs are prone to sudden onset, so we must adhere to the principle that prevention is more important than cure, supplemented by drugs to prevent diseases. You can sprinkle 1 mg/L oxytetracycline powder, 0.5~ 1 mg/L furazolidone, 1~2 mg/L zinc sulfate, 05 mg/L Xieanling and other drugs alternately on a regular basis; Feed medicinal bait frequently, and reuse 0.1~ 0.2g oxytetracycline or erythromycin for every1000g crab. Appropriate amount of shell powder, bone powder, fish powder and poultry eggshell powder are added to the feed to facilitate the shelling of river crabs. Parasitic diseases can be sprayed with 5~ 10 mg/l formalin or other pesticides in the whole pool, bacterial diseases can be disinfected with disinfectant for 2~3 times, and the effect is better if the whole pool is combined with feeding bait.
Prevent the loss of escaping crabs: crabs are most likely to escape in summer, frost and early autumn. Always check the escape prevention facilities, observe whether there are any signs of escaping, check whether there are holes connected with the external rivers and paddy fields, and solve problems in time. Check the retaining equipment at the outlet to prevent problems before they happen.
Feeding skills of crabs
Crab is an omnivorous aquatic animal. Its bait has the following kinds, but it cannot be fed with a single feed.
(1) Natural bait All kinds of creatures that it likes to eat and naturally grow in water and land are called natural bait. There are mainly phytoplankton, aquatic plants, benthos and terrestrial plants.
Phytoplankton: including diatoms, Chrysophytes, dinoflagellates, gymnosperms, green algae, etc., which are the feed for early young crabs and zooplankton.
Zooplankton: rotifers, cladocera, cladocera, etc., are its good feed.
Aquatic plants: including Sophora alopecuroides, hydrilla verticillata, Potamogeton crispus, POTAMOGETON malayi, Spiraea japonica, Spiraea crassipes, Alternanthera philoxeroides, etc., are its main natural bait.
Benthic animals: snails, clams, mussels, water worms, etc. in waters are its best feed.
Terrestrial vivid plants: including Tenebrio molitor, earthworm, ryegrass, Pennisetum, comfrey, etc.
(2) Artificial feed Plant feed mainly includes soybean, bean cake, vegetable cake, cottonseed cake, wheat, rice bran, bean dregs, distiller's grains, sauce dregs and peanut cakes. Animal feed mainly includes snails, clams, mussels, silkworm chrysalis, Tenebrio molitor, earthworms, small miscellaneous fish, fly maggots and internal organs of livestock and poultry.
When putting in feed, we must adhere to the principle of reasonable collocation of fine, green and coarse. Generally, the daily feeding amount is 5%-8% of the crab's weight. However, crabs have the habit of gluttony for animal feed, so it is difficult to change it into plant feed in a short time if animal feed is put in for a long time.
The feeding method is different from other aquatic animals, but basically it should also be "four fixed" (timing, positioning, qualitative and quantitative ... >; >

1 It is best to use a covered fish tank to prevent crabs from escaping. Plant a water plant and put some pebbles and sand to simulate the wild living environment of crabs more realistically. Crab is also a cave animal, so it's best to pick up a tile, wash it and put it in a fish tank, so that it can live in it. You can also use the shrimp house. Crabs should also bask in the sun, but not for too long. 2, feed crabs to eat bread crumbs, potato chips, steamed bread chips, rice, snails, small fish and shrimp and other foods. 3. Change the water once a week. It is best to use natural running water, river water and lake water. If not, use tap water that has been dried for two days. The water should not pass through the back. 4. When the crab is shelled, the shell is yellow, and the body is soft after shelling. It should be raised separately from other crabs to avoid cannibalism. And feed more meat food, such as small fish and shrimp. If successful, they will bring you a lot of fun. I hope I can help you, friend.
How to raise live crabs?
Environment: The bigger the ordinary fish tank, the better. It will be OK as soon as the water is full at the bottom of the tank. Change the water in two or three days. If you are hardworking, put some stones in it (be careful that he runs away with stones). However, you should always clean stones, which is very troublesome. I didn't put them in my fish tank.
Diet: Crabs are not picky eaters, so you can feed shrimps (crabs catch themselves or dried shrimps) in the water! Noodles, eggs, cabbage, dried beans, chicken, beef, etc. In short, crabs that people can eat are almost edible! It's better to be cooked, raw will make the fish tank fishy!
Food intake: feed him once or twice a day, one third as big as his foot, and clean up the residue in time!
Teasing: stir him with a stick, and after getting acquainted with you, he will not be afraid of you.
Cleaning: (cruel) Fix the crab with your hands, and then brush him with a toothbrush dipped in bath lotion or soap, especially in the dead corner, pulling his feet (not too hard). Wash the fish tank with water after bathing, and sprinkle some salt occasionally, mainly to prevent infectious diseases.
Note: when you hold him, he should not be higher than 20 cm, otherwise he may fall and be disabled. He should have as much activity space as possible, not too small! ! !
By the way, the crab has just arrived in a strange environment, and his temper is very stubborn. If you starve him for a few days, then use tweezers to make a delicious one and shake it in front of his mouth, and then you will see his voracious appearance.
How to feed domestic crabs
Do you mean pet crabs?
Rice, fish and shrimp, but fresh.
Change the water once a day or two, and it's better to have a small beach. Small crabs don't like to stay in the water all the time.
Speaking from experience.
How to raise small crabs?
I've raised it many times! ! Look at how many you want to raise first, and then decide how big a container to use to hold it. I usually put it in a small pot. Crabs, of course, like to eat meat, but you can feed them cooked meat (because I don't know how big you are raising), and you can also put some small fry, but it's almost winter now, so it's enough to give them little water. If there is too much water, they will freeze to death in another one every week. Just buy a small net, fish them out one by one, put them in, and they will crawl happily, let them play for a while, and then put them back. Before putting them back, wash the original basin. (If you put food in, you must change the water for at most 3 hours, otherwise it will pollute the water quality and lead to their death.) Just feed them once a week, just on the day when they are free to move. ! What I just said is the method of raising in winter, but now it's summer: more water, just half of the container, and some water plants and small stones to hide them. Put the basin in a sunny place and spend the summer like this! ! _ _ _ Also, you generally don't eat anything in winter ... You must pay attention to the density of breeding when feeding, otherwise you will find that they are decreasing day by day. When it molts, you must never touch it, which means it is the most fragile. After molting, you should take it out and raise it alone for a few days, and then put it back when its new shell hardens. It can eat anything, but the most ideal thing is meat.
