In recent years, as living standards have improved, the demand for Huangqi has steadily increased. Farmers have also enhanced their artificial breeding techniques, leading to significant economic returns. This has made Huangqi farming an attractive and profitable option for many.
First, the construction of a suitable habitat for Huangqi is essential. To ensure optimal growth conditions, it's important to create an environment that mimics its natural habitat. A typical pool size ranges from 40 to 50 square meters with a depth of about one meter. The pool should be rectangular or square, constructed with bricks and cement to prevent leaks. The bottom should be at least 30 centimeters deep, and the water level should be around 20 centimeters to allow proper breathing. Rocks and tree roots can be added to simulate natural crevices where Huangqi can hide. The pH level should be maintained between 6.5 and 6.8, and aquatic plants can be introduced to improve water quality and provide additional cover.
Second, selecting and transporting the seedlings is crucial. It's best to use artificially propagated seedlings or naturally sourced ones that are healthy. Healthy seedlings have a strong body, smooth skin, no mucus, and active movement. They should have a deep yellow color without scars. Stocking density depends on the size: for example, 25 grams per square meter allows 100-120 seedlings. Before placing them in the pool, they should be disinfected using 2%-3% saltwater or 100 mg/kg potassium permanganate for over 10 minutes. The temperature of the disinfectant must match the pool water to avoid shock. After disinfection, they are ready to be introduced into the pool.
Third, feeding and managing Huangqi requires attention to detail. Huangqi is an omnivorous fish that can be fed with quail, fly larvae, small fish, shrimp, snails, or other animal by-products. A small amount of wheat gluten, vegetables, and fruit peels can also be included. However, it's important to feed only fresh bait, as spoiled food can cause illness. Feeding should start after three days of acclimation, and the feeding time should gradually shift to a consistent schedule, such as 10 AM or 3 PM.
The feeding amount should vary depending on water temperature. The ideal temperature range for growth is 15–30°C, during which more food should be provided. Dry feed should be 3–5% of the total weight, while fresh bait should be 5–10%. When temperatures drop below 15°C or rise above 30°C, feeding should be reduced, and the "four principles" (timing, location, quality, and quantity) should guide feeding practices.
Daily management involves maintaining clean water, changing it every two days, and increasing depth during colder seasons. In hot weather, oxygen levels must be monitored, and measures like water injection or aeration should be used. During rain, check for blockages and ensure fences are secure to prevent escape. Regular inspections of the pond are necessary to detect and address any issues promptly.
Finally, disease prevention is key. Although Huangqi is resistant to most diseases, it is prone to injuries and hydromycosis early in the feeding stage. Before introduction, affected areas should be treated with 5% iodine or immersed in 4% saline for 3–4 minutes. Weekly disinfection of the water is recommended using sodium chlorite at 0.3 g/m³ or quicklime at 5–10 g/m². Maintaining a clean and stable environment is the best way to prevent health issues and ensure successful breeding.
