1. The family raises the pot to raise them. The pot can put some fine sand and form a small platform. The water to be raised must not be too deep. The best water depth is that the water has just been immersed in the shell of the crab, and the water used for feeding can be tap water, but it must be used in the sun for one day.
2. Crabs can basking in the sun, but they can't stay in the sun for too long.
3. Crabs are omnivorous animals. If they can, they can feed red nematodes. They can feed yolks. Of course, crabs can also eat viscera or chicken shrimp. At the same time to feed some grass food. Pay attention to the amount of food you eat, and eat within half an hour, otherwise the remaining food will contaminate the feeding water.
4. The feeding intensity of crab increases or decreases with the change of season and water temperature. In summer and autumn, as the water temperature rises above 15°C, crabs have increased feeding capacity, and they are fed once a day. When the water temperature drops below 15°C, the crab's feeding ability drops and can be fed once every other day or several days. The feeding time is appropriate around the evening. This is because crabs are aquatic animals that are nocturnal.
5. Crabs are social animals. It is best to keep several crabs together so that the survival rate is relatively high.
6. When helping crabs, use your hands to hold the crabs in place, then use a toothbrush to dip in shower gel or soap to clear it, especially at the corners, and pull its feet (don't push too hard). Clean water, wash fish tanks, and sprinkle salt occasionally, mainly to prevent infectious diseases.
7. Crab just arrived in an unfamiliar environment. His temper was very embarrassing. Hungry for a few days. He took a delicious meal with a scorpion and dangled it in front of his mouth. Then he saw it wolfing down.
2022 New Laser Distance Sensor
At the start of 2022, JRT introduce our customers a batch of new series laser distance measurer sensor(S92-20m, S91, BA6A-150m, BA6A-20Hz, M703A-8Hz, U81-10m etc.). Especially S91(RS485 interface and software Rx Tx protocol) and S92(RS232 interface) ip54 enclosure distance sensor model, custoemrs would like to use it in their industrial automation solutions,according to the ip54 waterproof protection level, well protect laser, Wide Voltage 5~32V(Optimize for industrial using), and easy-to-install.
