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, and some pebbles must be added in the fish tank, so that the crab can climb and escape.
2. Crabs need proper sun exposure during their growth. Ultraviolet rays in the sun can promote their growth, and also help small crabs to shell. When the weather is hot, it is necessary to avoid direct sunlight on crabs and keep them in the sun for too long.
3. 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 changed frequently. Only by keeping the water clean can they avoid getting sick.
What feed do crabs eat?
1 Crab is an omnivore, which mainly feeds 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 the crab is artificially raised, it can be fed with animal bait, such as fresh and fresh fish, snail meat and so on. Slowly increase the amount of concentrate feed, such as wheat, corn, soybean meal, etc. If it is in high temperature season, less plant concentrate bait and more green coarse feed, such as aquatic plants, pumpkins, potatoes, etc.
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 crab treasures for feeding, and the effect will be very good.
