1. Fish tanks can be used as containers for domestic crabs. The aquaculture water level must reach 1/2 of the crab's body, or just overflow the shell of the small crab. Some pebbles must be added to the fish tank so that the crab can climb up and escape.

2. Crabs need proper sunlight during their growth. Ultraviolet rays in the sun can promote their growth and help small crabs to shell. When the weather is hot, avoid direct sunlight on crabs, and don't expose crabs to the sun for too long.

Because crabs prefer to eat meat, they can be fed with snail meat, fish meat and shrimp meat when they are raised, which can make them grow healthier. Usually, they should be replaced frequently. Only by keeping the water clean can they avoid getting sick.

What feed do crabs eat?

1. Crabs are omnivores, mainly feeding on aquatic plants, benthos and organic debris. It likes many foods, such as snails, shrimps, mussels, small fish and pumpkins, cooked potatoes, rice dregs, bread dregs and so on.

2. If crabs are raised artificially, they can be fed with animal bait, such as fresh fish and snail meat. Gradually increase the amount of concentrate feed, such as wheat, corn, soybean meal, etc. If it is in the hot season, eat less plant concentrate bait and eat more green roughage, such as aquatic plants, pumpkins, potatoes and so on.

3. When crabs enter the late stage of culture, they can be given plant concentrate feed and animal bait, which can ensure that crabs are full and eat well. In the process of feeding, you can occasionally feed some fat crabs, and the effect will be very good.
