Catfish fry stocking management technology

After purchasing the seedlings, they are raised in a small pool with the water temperature maintained around 28°C. The primary food source is microorganisms naturally present in the water. During this period, the seedlings gradually recover from any injuries and adapt to the warmer environment. Before stocking them into the ponds, the ponds must be thoroughly disinfected to ensure a clean and safe environment for the fish. 1. Seedlings are selected based on their deep coloration, absence of injuries, and small body size. Any unqualified individuals are kept in separate ponds for further observation or culling. 2. The living water holding system involves placing the quail in double-layer net cages, which should not be located directly in river currents. Each cage holds approximately 100 kg of quail. The dimensions of each cage are 3.3 meters long, 1.7 meters wide, and 2 meters high, ensuring that the netting extends 80 centimeters above and below the water surface. It's important to monitor water levels regularly. During thunderstorms, there must be dedicated guards to prevent accidents. In cloudy, rainy, or foggy weather, aerators should be used to maintain oxygen levels in the water. Additionally, waste materials should be removed promptly to keep the cages clean and hygienic, promoting healthy growth and reducing the risk of disease.
