Treatment tank: the silt at the bottom of the tank shall not exceed 20cm. Stocking crab seedlings: Choose healthy and energetic crab seedlings and put them in the pond. Feeding food: When breeding crabs, you can feed egg yolk or animal viscera. Note: when the temperature is low in winter, crabs will eat less, which can reduce the feeding frequency.

Crab culture method 1, pond treatment

Crabs should be cultured in ponds with sufficient water and clean water quality, and the silt at the bottom of the pond should not exceed 20 cm. Several water piers can be built in the pond, on which aquatic plants can be planted, and then 75 kilograms of quicklime slurry can be sprinkled for disinfection before the crabs are released 15 days.

2. Stocking crab seedlings

Choose healthy and vigorous crab seedlings and put them in the pond. Before stocking, let them stand in water for 2-3 minutes, then take them out and stand for 65,438+00 minutes. Repeat this for 2-3 times, so that the crab seedlings can adapt to the water temperature as soon as possible and resume growth. Each acre can be stocked with 1500 crab seedlings.

Step 3 feed the food

Crabs are omnivorous animals, feeding on water worms, small fish and shrimps. You can feed egg yolk or animal offal when breeding. Pay attention to the feeding amount when feeding, cut the food into small pieces and feed about 2 pieces at a time. You can't feed too much.

4. Preventive measures

Crabs are sensitive to environmental changes, and may stop eating or run away at the beginning of breeding, so they can't be provided with food for three days before breeding. At the same time, when the temperature is low in winter, crabs will eat less, which can reduce the feeding frequency.
