Culture method of hairy crabs 1, culture environment
Hairy crabs have high requirements on the breeding environment. They should choose a place far away from the urban area, without factories around and rich in water resources. After draining the pool water for disinfection and insolation, they should inject new pool water with a depth of about 2 meters, and the water temperature of the pond should be controlled at 20-25 degrees.
2. Stocking crab seedlings
When breeding hairy crabs, crab seedlings with uniform shell color, similar body size and complete limbs are selected. After disinfection, they are stocked on cloudy days or in the evening. When stocking, they should first adapt to the pond water temperature, and the breeding density is about 300 crab seedlings per mu.
3. Feeding method
Hairy crabs are omnivores, which usually lie in the daytime and come out at night. They are fed once a day at 5 am and 8 pm respectively. In spring and summer, they are mainly fed with plant feed, with a small amount of animal feed, while in autumn and winter, they are mainly fed with animal feed.
4. Daily management
When breeding hairy crabs, it is necessary to change the water regularly, every 15 days in spring and autumn. In summer, the high temperature water quality is easy to be turbid, so it is necessary to change the water once a week. The water exchange amount is 1/3 of the pond water, and it is necessary to patrol every morning and afternoon.
