Pond environment: hairy crabs should be cultivated in a place with good water quality, no pollution and far from traffic, which is divided into deep water area and shallow water area. Water quality environment: In order to ensure good water quality, aquatic plants such as duckweed and reed grass should be planted in the pond. Temperature environment: Hairy crabs grow rapidly in the environment of 25-28 degrees, and the water temperature of breeding should not be lower than 10 degrees.

What are the conditions for hairy crab breeding 1, pond environment?

To cultivate hairy crabs, we should choose sites with fresh and pollution-free water, far away from traffic, residential buildings and factories, and use cement and bricks to build ponds with an area of 15 mu, about 20 in number, which are divided into deep water areas and shallow water areas, which are more conducive to the growth of hairy crabs, and slopes should be set in the ponds to facilitate the activities of hairy crabs.

2. Water quality environment

Hairy crabs are suitable for growing in an environment with good water quality. In order to ensure the good water quality during the breeding period, aquatic plants such as water peanuts, duckweed and reed grass should be planted in the pond, and the water quality should be adjusted by using the purification function of plants. Pay attention to the planting area of 70%-80% of the total pond area.

3. Temperature environment

Hairy crabs are temperature-changing animals, which adjust their temperature according to the change of water temperature. Generally, when the water temperature is between 25-28 degrees, hairy crabs grow fastest, and the temperature is lower than 10 degrees and higher than 30 degrees, and the growth speed is slow. Therefore, when breeding hairy crabs, temperature control equipment should be installed in the pond to keep the temperature at about 25 degrees.
