Andrias davidianus as an amphibian, possesses values such as food and medicinal uses. Its breeding and cultivation techniques based on practical production practices in the Huainan area of Anhui Province, covering site selection, farming facility construction, artificial propagation, artificial cultivation, and disease prevention and control were summarized. Andrias davidianus prefer shade and dislike light, favor quiet environments, and are sensitive to disturbances; the site should be secluded with ample feed resources. Breeding ponds should be constructed in shaded and ventilated underground rooms, divided into larval ponds, juvenile ponds, adult ponds, broodstock ponds, spawning ponds, and hatching ponds. Supporting facilities such as sedimentation ponds, filtration ponds, purification ponds should also be built. For artificial propagation, broodstock should be healthy, free of injuries or diseases, and weigh at least 2 kg. In broodstock ponds, a female-to-male ratio of 3∶2 is recommended for mixed breeding or separate rearing, with a stocking density of 1 individual/m2. Breeding is divided into spring cultivation (April–May), pre-spawning cultivation (June–July), and autumn cultivation (August–September). The optimal time for induced spawning is August–September, with water temperature controlled at 16–23 °C. A flow-through method is used for incubation, with a flow rate of 2 m3/h, dissolved oxygen concentration >3 mg/L, and avoidance of light exposure.Artificial cultivation is divided into three stages: larval, juvenile, and adult. The larval stage requires strict control of water temperature (10–23°C), stocking density (30–50 individuals/m2), and thorough disinfection. Juvenile cultivation emphasizes graded management (6–10 individuals/m2) and“four fixed”feeding principles (fixed time, location, quality, and quantity). For adults, feeding rates (0.3%–10%) are precisely adjusted based on water temperature.Disease prevention follows a proactive approach. For parasitic diseases (trichodinosis), formalin baths are used; bacterial diseases (furunculosis, enteritis) are treated with povidone-iodine disinfection and antibiotics; fungal infections (saprolegniasis) are managed with salt baths and metalaxyl application. This study provides a reference for the healthy cultivation of Andrias davidianus.
