How to raise hairy crabs, how to raise hairy crabs

Breeding environment: the breeding environment of hairy crabs is not complicated, select a clean and pollution-free water area for breeding, it is best to choose lake water aquaculture, such as lake water and other waters, you can build a sluice, do the corresponding drainage engineering.

Selection of excellent breeding: before breeding, it is necessary to select high-quality hairy crab breeding, due to the first breeding, combined with factors such as water environment, the survival rate may be low.

Feeding: Hairy crabs should be fed with small fry, and it is best to keep the nursery alive, as dead fish can easily lead to the death of hairy crabs.

Improve water quality: Some aquatic weeds can be properly cultivated in the water, which can improve the water environment and make the water not so turbid.

Hello dear and happy to serve you. Hairy crab breeding method: 1. Prepare the container:

Prepare a separate container for domestic hairy crabs, and if you are growing them for a short time, you can use a washbasin and sink. 2. Water quality: The tap water for breeding hairy crabs should be dried first, and it can be used after 2 days of exposure.

3. Feeding: For short-term breeding of hairy crabs, you do not need to buy special food, you can feed some grain crumbs, rice, millet, etc. 4. Water change:

To breed hairy crabs at home, you need to change the water once every 3 days or so, and you can drop one of the branches of the potato stove every time you change it.

To raise hairy crabs, it is necessary to prepare suitable breeding grounds to ensure that the water quality is clean and to avoid hairy crabs from getting sick. In summer, hairy crabs breed, you can feed it more corn, pumpkin and other nutritious feed, in winter hairy crabs grow meat, you can feed hairy crabs to eat earthworms, snails, fish and shrimp and other animal feed, and pay more attention to water change in ordinary times.

When raising hairy crabs, you need to prepare a breeding ground with a large space, it is best to plant some aquatic plants, and ensure that the water for raising hairy crabs is clean to avoid the disease of hairy crabs caused by unclean water.

Summer is the time for hairy crabs to breed, so they need to be fed some corn, pumpkin and other plant feed, and in autumn, when hairy crabs grow meat, you can feed more hairy crabs to eat earthworms, snails, fish and shrimp and other animal feed.

In normal times, it is necessary to avoid hairy crabs getting sick, and it is necessary to change the water frequently to avoid not changing the water for a long time, breeding more bacteria, and infecting hairy crabs.

Water quality regulation: When breeding hairy crabs, keep the depth of the pond water between 70-80 cm. Regular feeding:

Hairy crabs are fed at 5 a.m. and 8 p.m. every day, and the feeding amount is 4% of the total body weight. Pond disinfection: Regularly sprinkle microbial agents on ponds to remove nitrites.

Regular patrols: Patrol twice a day to prevent hairy crabs from escaping.

1. Water quality regulation

In the process of breeding hairy crabs, the depth of the pond water should be kept at about 70-80 cm, to create a good growth environment for it, in the hot summer, to inject water into the pond, keep the water depth between 110-120 cm, and find that the water quality is turbid, the visibility is too low, to replace the clear water for the hairy crabs, and the amount of water exchange is 20%-25% of the total pool water.

2. Feed regularly

Hairy crabs are nocturnal during the day, during the breeding period to choose the feeding time according to the habit, 5 o'clock in the morning, 8 o'clock in the afternoon hairy crab activities are frequent, feeding bait can be carried out at this time, and the first half of the main feeding plant feed, with animal feed, in the second half of the year to animal feed, plant feed as a supplement.

3. Pond disinfection

Hairy crabs mostly live at the bottom of the pond, and the bottom of the pond is piled up with food residues and feces, which is easy to produce nitrite, resulting in the poisoning and death of hairy crabs, so in the process of breeding, it is necessary to regularly sprinkle microbial preparations on the pond to eliminate nitrite, and to splash lime water on the pond to remove harmful organisms.

4. Regular inspections

Hairy crabs are good at burrowing, climbing, during the breeding period to regularly inspect the pond, and for the pond to strengthen the purse seine or anti-escape device to prevent hairy crabs from escaping, and in the process of inspection, found that the hairy crabs with poor growth and infection of diseases, they should be fished out in time and fed separately to avoid large-scale infection.

1. Water quality adjustment: When breeding hairy crabs, the depth of the pool water should be kept between 70-80 cm.

2. Regular feeding: Hairy crabs are fed at 5 a.m. and 8 p.m. every day, and the feeding amount is 4% of the total body weight.

3. Pond disinfection: regularly sprinkle microbial preparations on the pond to remove nitrite.

4. Regular inspection: Patrol twice a day to avoid hairy crabs escaping.

1. How to feed hairy crabs
