The method of raising crabs at home is 1. Keep medicine cans at home. You can put some fine sand in the flowerpot to form a small platform. Don't feed the water too deep. The best water depth is that water steel is soaked in crab shells, and the water to be fed can be tap water, but it can only be used after a day of sun exposure.
2, crabs can bask in the sun, but not for too long.
3. Crabs are omnivores. If possible, they can feed red nematodes and egg yolks. Of course, crabs can also eat chicken and duck viscera or small fish and shrimp. At the same time, feed some grass. Pay attention to your food intake and finish it in half an hour, otherwise the remaining food will pollute the raised water.
4. The feeding intensity of crabs increases and decreases with the change of seasons and water temperature. In summer and autumn, when the water temperature rises above 15℃, the crab's feeding ability is enhanced, so it is fed once a day. When the water temperature drops below 15℃, the feeding ability of crabs decreases, and they can be fed once every other day or several days. Feeding time should be around the evening, because crabs are aquatic animals, lying in the daytime and coming out at night.
5, crabs are social animals, it is best to raise several crabs together, so the survival rate is relatively high.
6. When cleaning the crab, hold the crab with your hand, and then brush it with a toothbrush dipped in shower gel or soap, especially in the dead corner, and pull its feet (don't brush it too hard). Wash the fish tank with clean water after bathing and sprinkle some salt occasionally, mainly to prevent infectious diseases.
7. The crab has just arrived in a strange environment and has a stubborn temper. If you starve it for a few days, hold a delicious one with tweezers and shake it in front of its mouth, and then you will see it gobble up.
Crab culture method 1. Tools for breeding: you need a small glass fish tank (preferably a turtle tank) because it is easier to observe crabs? Every move? Moreover, this kind of fish tank is easy to buy and cheap.
2. After buying the jar, spread a layer of baby's sand at the bottom of the jar, about one centimeter thick. Don't use pebbles, it will hinder the crab from walking.
3. About adding water: put the crab into the tank and inject clear water just below the crab's back. Too deep or too shallow is not good. You should also add a little salt to the water. Don't add too much to help the crabs disinfect.
4. About food: Generally, the food of crabs is red fish worms for fish, which are also easy to find and not expensive. A few dollars can buy a lot, but one disadvantage is that it is easy to die and deteriorate.
5, feeding taboo: avoid crabs exposed to the sun for too long, so as not to be killed by high temperature.
Matters needing attention in crab culture
First, we must close the source. The origin refers to the parents of crabs.
Second, we must do a good job in clearing the pond. Disinfect the pond with lime, bleaching powder, etc. So as to eliminate pathogenic bacteria remaining in the pond.
Third, we must close the environment. Planting aquatic plants and throwing snails at the bottom of the pond can provide natural bait for crabs and improve the self-purification ability of water bodies.
Fourth, we should put good investment into practice. Whether it is preparations for cleaning ponds, bait or biological preparations for regulating water quality, it must be strictly regulated by the aquatic products department. Prescription? Use and eliminate all illegal drugs.
