1 Pond conditions
1. Pond environment. Pond area is generally suitable for 5-10 acres, water depth 1.5-2,5 meters, good water quality, abundant water, convenient drainage, no pollution; pond bottom flat, hard, generally not more than 20 cm thick silt , pool pool solid watertight.
1.2 clear pond fertilizer water. Removal of debris and silt at the bottom of the pond, including dry pond and tap water. Dry pond method: Use 60-75 kg of lime per acre, keep 8-10 cm of water in the pool, and mix the sludge and lime slurry at the bottom of the pool; with water method: water depth of 50 centimeters per mu, use lime 100-125 kg The whole pond of lime slurry is sprayed evenly, and fish species can be released after 7-10 days of disinfection. After 5-6 days, water is poured into the pond and the water depth is 1.5-2.0 meters. At the same time, put into the hot chicken, duck and other animal droppings stick Hefei 100-150 kg, training water to tender green or dark brown, transparency is about 35 cm.
2 Stocking stocks for fish stocks are 80% for carp and 20% for other fish species such as whitefish. The seedlings must be tested for water for 24 hours before stocking. If there are no abnormalities, fry can be officially released when the average water temperature reaches 6°C-8°C. Fish seedlings in front of the pond with 10 mg / kg of potassium sulfate solution, bath for 3-5 minutes; or 3% -5% saline bath for 5-10 minutes.
3 Feeding management
3.1 Feed Management. According to the normal pond fish rearing and management, the amount of fish feed pellet feed, feed every day should be on time, fixed, select the appropriate size of bait size, water stability, low feed coefficient, according to the principle of a small number of times, when the water temperature Below 20 °C, feeding 1-2 times a day, when the water temperature is above 20 °C, feed 3 to 4 times a day, feeding time is arranged at 8:00-18:00. According to the season, weather, water color, and eating conditions, 80% of the fish eaten as a walk, then reduce feeding or stop feeding.
3.2 Adjust water quality. Lime solution is applied once every 20 days for 25-30 kg/mu in order to improve the water quality and keep the pH value of the pool water between 7-7.5: Apply calcium superphosphate once every 15 days. 15-20 kg/mu. Lime calcined for 3-5 days before application of lime, to prevent excessive alkaline water to reduce the effect of phosphate fertilizer. Throughout the entire cycle, the pond should maintain a proper amount of water, change the water every 10 days or so depending on the situation, change the depth of water by 15-20 centimeters each time, and use an aerator to keep the pond in good water quality conditions. The high temperature season should be timely. Turn on oxygen.
4 Daily management adheres to dedicated personnel on duty, often patrols the pond, observes the dynamics of the fish in the pond, patrols the pond early, mid and late every day, observes the presence or absence of floating heads and the degree of floating heads before dawn, and combines feeding and testing during the day. Water temperature and other work, check the fish activities and eating conditions; in the hot season, when the weather suddenly changes, you should also meet the pond around midnight to prevent flooding.
5 Disease prevention and control is mainly based on prevention. For bacterial fish diseases (eg, erythrascus, gill rot, enteritis, etc.), 1 mg/kg of bleached powdered water is sprayed on the whole pool every 15 days. Parasitic fish disease is performed monthly. Secondly, each time 0.5 mg/kg of copper sulfate + 0.2 kg/kg of ferric sulphate mixture is used for water spilling; the main prevention and control of trilobite worms, tick whipworms and other protozoan parasites and Chinese rubiosis; 0.3 -0.5 mg/kg crystal trichlorfon or agricultural enemy killing (used at a rate of 6-10 ml per 1 meter depth from the water) Quanchiposa, used to control larvae of parasites such as anchor-headed turtle, Chinese sturgeon, etc. .
