Mud ponds for efficient breeding

The aquaculture site should be as close to the water source as possible, the water quality should be clean and free of pollution, and the drainage should be convenient. The soil is neutral or slightly acidic viscous soil, with plenty of sunshine, convenient transportation and power protection. The aquaculture ponds are long strips with an area of ​​2-3 mu, a depth of 0.7-1 m, a water depth of 0.5-0.6 m, and mud in the pond walls should be compacted. The perimeter of the pond is surrounded by a mesh sheet. The bottom of the mesh sheet is buried in hard soil and the upper end is 20 cm above the water surface, which can effectively prevent the muddy escaping and the entrance of enemy creatures. At the bottom of the pond, 15-20 cm thick mud is set. The water inlet is 20 cm above the water surface. The outlet is set at the bottom of the pond and is normally sealed. Inlet and outlet are protected by wire mesh.

Second, the stocking mode

1. Prepare before stocking: clear the Dianchi Lake 10 days before putting it to rest, plug the loopholes, clear the drainage pipes, and plow the silt in the bottom of the pond, and then disinfect it with quick lime. 10 centimeters of water per acre of pond use quicklime 70-80 kilograms. Immediately after the slurry is converted into slurry, the entire pool is splashed. After 3 days of clear pond, add 30 centimeters of water, apply 50 kilograms of chicken manure per acre, spread evenly in the pool, or use 100 kilograms of pig, cattle, and sheep manure to concentrate and stack it in the fish slip, let it ferment and decay, and then treat the water as fat and thin. Fertilization. The transparency of the water is 20 centimeters, and it is better to not see the bottom mud.

2, seed stocking: in April when the water temperature rose to above 15 °C to begin stocking, per acre stocking specifications 70-80 tail / kg of seed 1000-1500 kg, or 100-120 / kg of seed 800-1000 kg. Before the stocking, they were sterilized with 3-5% saline and the immersion time was 5-10 minutes. The stocks stocked in the same pool are required to have even and neat specifications, and the specific stocking amount should be flexibly controlled according to factors such as ponds and water quality, feeding and management levels, and planning out-pool specifications.

Third, daily management

1. Feeding: When the water temperature is above 15°C, the loach appetite gradually increases, and the appetite at 25-27°C is particularly strong. When the temperature is higher than 30°C or lower than 12°C, less food or even feeding should be stopped. When the water temperature is below 20°C, the main food intake is plant-based food, accounting for 60-70%; when the water temperature is 21-23°C, the animal and vegetable diets account for 50% each; when the water temperature exceeds 24°C, the plant food should be reduced To 30-40%. The animal feeds for loach feeding include animal viscera, earthworms and small trash fish. Botanical diets include soybean meal, vegetable jelly, wheat bran, and cereals. Normally, they are fed once a day in the afternoon and afternoon, and the daily feeding amount is 4-10% of the loach's body weight. Feeding should be based on the water quality, weather, and food conditions. The next day, no food is left in the early morning or a few leftovers are seen. Feeding should be scheduled, fixed, qualitative, and quantitative. General breeding can be harvested in about 4 months. If the market conditions are good, it can be harvested in advance and then stocked with a loach.

2. Water quality regulation: The quality of aquaculture pond water quality is extremely important for the growth and development of loach. The pond water color is preferably yellow-green, and the transparency is preferably 20-30 cm. When the water becomes dark brown, dark brown, or when the body's dissolved oxygen is less than 2 mg/l, fresh water must be added in time to replace some of the old water to increase the dissolved oxygen in the pool and to avoid stress response from the loach. It is usually applied once every 15 days, each time about 15 kg of organic fertilizer is applied per acre. According to the specific conditions of the water color, 1.5 kg urea or 2.5 kg ammonium bicarbonate may be applied per acre per time to keep the pool water green and yellow.

Fourth, key measures

It is mainly necessary to strengthen the process of patrol ponds, and take a patrol of the pond three times a day. The first is to inspect the dams, plug loopholes, maintain the water level, prevent floating heads and pans, and observe the occurrence of muddy feeding, activities and diseases, and clean up the food in time. The third is to prevent snakes and ducks from entering the pool to harm the loach. Fourth is to use organic fertilizer regularly to keep the pool water, live, and cool. The fifth is to ride a awning on the fish during the summer, or shallow water or drainage in the winter. . From June to October every two weeks, chlorine dioxide is used to disinfect once a day, and once a day, lime is splashed with lime for one time. It is also possible to use a combination of probiotics. When the weather is hot, low pressure, thunderstorms, or rainy days, it should be observed whether or not it is floating. If the floating head is serious, new water should be added in time to make a good record of breeding.
