The full artificial propagation of *C. chekinensis* remains a challenge that has not been fully resolved yet. Therefore, experts recommend that artificial breeding is the most effective method for raising *C. chebriformis*. For farmers with limited resources, semi-artificial propagation can also be considered as an alternative approach.
In artificial breeding, it is recommended to start from July to September. Select suitable breeding areas such as ponds, low-lying fields, or shallow grassy lakes that have not been previously used for crayfish farming. Place 18 to 20 kilograms of broodstock per acre, maintaining a male-to-female ratio of 3:1. When releasing the broodstock, ensure the water depth is at least 1 meter. After release, gradually drain the water to maintain a depth of 0.4 to 0.6 meters. By late October, slowly refill the pond so that the water just covers the crayfish burrows. No feeding is required during autumn and winter, but aquatic plants should be added, along with moderate fertilization to keep the water clarity between 30 to 40 cm. Once a significant number of juveniles hatch, use cages to collect the newly bred shrimp. Maintain a water depth of more than 0.6 meters in winter. If the daily average temperature drops below 4°C, the water depth should be increased to at least 1 meter. At the beginning of March, when the water temperature rises above 10°C, the shrimp will leave their burrows and become active. At this point, management should be intensified—lower the water level slightly to warm the water and begin feeding and fishing activities.
For semi-artificial propagation, construct rectangular clay ponds measuring 40 to 50 meters long and 6 to 7 meters wide, with a slope ratio of 1:1.5. Install a 50–60 cm high anti-flood net around the pond. Cover the soil pond with a shade net, and maintain a water depth of about 1 meter. At the beginning of July, introduce broodstock at a rate of 180–200 kg per pond, which equals approximately 400–450 kg per acre. The male-to-female ratio should be either 2:1 or 5:2. After releasing the broodstock, maintain good water quality and use microflow techniques if available. Feed the crayfish once daily, providing high-protein animal feed and adding aquatic plants like water peanuts and water hyacinths. In mid to late August, start capturing male broodstock using shrimp cages. When juveniles appear in September, use cages to catch the females that have bred. Intensify feeding and manage hatching in batches to maximize production.
Broodstock selection typically occurs from June to September, and they should be collected directly from cultivated ponds or natural water sources. The male-to-female ratio depends on the breeding method. For semi-artificial propagation, a 5:2 or 2:1 ratio is preferred, while for artificial propagation, a 3:1 ratio is commonly used. Female broodstock should weigh over 30 grams, and males over 40 grams. It is crucial to minimize the time the broodstock spends out of water, ideally no more than 2 hours. Avoid adding ice to the broodstock, and never select them from the market, as this may compromise their health and breeding success.
