1. Polyculture of fish gills efficiently utilizes the water surface, helping to minimize sediment accumulation. By removing dead fish that may carry disease, their waste can be repurposed as organic fertilizer, while the water is used to cultivate plankton, which serves as natural bait for other fish species. This system supports recycling, fertilization, and enhanced fish growth, achieving three key benefits simultaneously.
2. A combination of oysters, snails, and loaches can be introduced after thoroughly cleaning and disinfecting the spring pond. Fresh water is then added to a depth of 40 cm to improve water quality and promote biological activity. Approximately 50-70 kg of field snails or 5-10 kg of loaches per mu are placed in the pond. Following this, fish gills are introduced, and the water level is gradually increased, creating an abundant natural food source for quail and significantly reducing feed expenses.
3. Artificial feed can make use of various readily available resources, such as by-products from agriculture and processing. Although quail might not typically prefer vegetable-based feeds, they can be trained to consume agricultural by-products like flour, soybean meal, wheat bran, and rice. These can be combined with animal-based feeds such as fishmeal, blood meal, silkworm pupae, and animal offal to create balanced formulated feed. This approach not only reduces the reliance on costly animal feed but also ensures that quail receive all necessary nutrients for optimal health and growth.
4. After preparation, rice and potatoes are soaked in water for 5 to 6 hours. Once sprouted, they are evenly distributed into Dianchi Lake at a daily rate of 5% of the total weight of the rice grains. Cooked and crushed rice and potatoes are mixed together and placed in basins at the bottom of the tank. The daily feeding amount should also be around 5% of the total weight of the pond contents. This method helps reduce the need for commercial animal feed, lowering overall production costs while maintaining good fish health and growth.
