You should pay attention to the following points for small crabs just caught from the sea

1. Find a basin with fine sand. The water for raising should be soaked in the crab shell. For sea water, you can buy special sea salt to mix with sea water.

2. Crabs can bask in the sun appropriately, but not for too long.

3. Crabs are omnivores and can be fed egg yolks, ham sausages, chicken and duck offal, small fish, shrimps, food or rice. At the same time, feed some plant feed.

4. The feeding intensity of crabs increases or decreases with changes in season and water temperature. In summer and autumn, as the water temperature rises above 15°C, the crab's feeding ability increases, and feeding is done once a day. When the water temperature drops below 15°C, the crab's feeding ability decreases, so it can be fed every other day or several days. Because crabs are nocturnal aquatic animals, they can be fed around dusk.

5. Clean the crab regularly. Hold the crab with your hands while cleaning, and then use a toothbrush dipped in shower gel or soap to brush it cleanly, especially in the dead corners. Rinse with water after bathing, wash the basin as well, and sprinkle some salt occasionally, mainly to prevent infectious diseases

6. Crabs will refuse to eat when they first arrive in a strange environment. You don’t need to feed them for the first two days. , and then gradually increase the feeding amount.

Extended information

The choice of crab pond should have sufficient water source, good water quality and convenient drainage. To ensure good air permeability, sand or sandy soil should be the main soil. The water depth in the pond is controlled at about 1m, and the shallowest place cannot be lower than 10cm. In the built pond, several mounds are left inside, and aquatic plants such as reeds, water bamboo, and calamus are planted. On the one hand, these aquatic plants are a good source of nutrients for crabs to eat. On the other hand, it is helpful to consolidate the river embankment and avoid water leakage caused by digging holes.

Crab seedling selection

Good varieties are the key to achieving high yields. Guarantee: Strong physique, neat specifications, and good adaptability. After selecting a good crab fry, first soak it in the pool for a few minutes, repeat the operation several times, and observe the crab's ability to adapt to the water quality. If there are no adverse reactions, you can put it in. At present, polyculture of crab fry and other fish species is the main method. On the one hand, it provides a food source for crabs, and on the other hand, it can improve the economic benefits of breeding.
