1. Adjust the feeding amount appropriately: When raising black quail in a pond with adult fish, the weight of the black quail should be included in the total feed quantity, and the overall feed amount should be increased accordingly. This increase is not solely for the black quail but aims to support the population of wild fish, small crustaceans, aquatic insects, frogs, and even cockroaches in the pond. To meet the nutritional needs of the black quail, it's also advisable to introduce species that can reproduce naturally, such as large tilapia, catfish, or oyster catchers. Their larvae and young can serve as additional food sources for the black quail. Large eels and other fish can still be raised as commercial species, thereby increasing the yield per unit area. 2. Plant aquatic vegetation: Black quail prefer to hide among water plants in shallow areas, where they can ambush small fish and shrimp. Therefore, it's beneficial to plant floating plants like water spinach, water hyacinth, and duckweed in polyculture ponds. These plants provide hiding spots for the quail, helping them hunt more effectively. If the quail don't blend well with the surrounding vegetation due to their coloration, capturing prey becomes more difficult. The planting area should not exceed 1/5 of the pond’s surface, and it should be placed in the shallow zones near the banks. The width of each planting area should be between 60–80 cm, not exceeding 1 meter. Overplanting can negatively impact the growth of farmed fish, affect water quality, and cause oxygen depletion at night. Additionally, aquatic plants offer breeding grounds for wild or self-reproducing fish and provide shelter for juvenile fish. A moderate amount of floating vegetation also helps shade the water and improve water quality. 3. Prevent escape: Black quail are skilled at escaping and moving against water currents. Therefore, the pond’s surface should be at least 30–40 cm above the water level, and anti-escape structures should be installed at the pond entrance and exit. After heavy rain, special attention should be paid to checking the escape prevention systems at the water outlets to prevent the quail from escaping. Also, check for any signs of quail trying to jump through small gaps or moist soil on land, as even a slight moisture or trickle of water can allow them to escape using a snake-like movement. 4. Avoid using ferrous sulfate: In polyculture ponds where black quail are raised alongside main fish species, care must be taken when treating diseases. Different fish species have varying sensitivities to medications. Common treatments for parasitic diseases include copper sulfate or a combination of trichlorfon and ferrous sulfate, which can be effective. However, black quail are highly sensitive to ferrous sulfate and can die rapidly if exposed. Therefore, during disease outbreaks, only copper sulfate or trichlorfon should be used, avoiding ferrous sulfate entirely. 5. Harvest as much as possible during winter dry-up: During the winter, when the main fish ponds are drained, it's crucial to catch as many black quail as possible. These fish are typically stocked between May and June and, after 5–6 months of growth, can reach weights of 150–400 grams, with some reaching up to 600 grams. If any remain in the pond, they can pose a threat to future fish stocks. Thus, it's essential to completely remove all black quail during the winter dry-up period. In winter, black quail often burrow into the silt, making them hard to catch. To ensure proper management in the following year, the pond must be thoroughly cleaned. It's recommended to choose shallow ponds with less silt for winter drying. If necessary, safe chemical treatments can be used to eliminate any remaining quail. organic hibiscus tea,red rose tea,best hibiscus tea,organic chrysanthemum tea,flowering tea gift set ZHONGSHAN G.H.L.
