Chengyu pond cleaning and disinfection
In the stage of breeding, the growth habits of the pupae are slightly different from those of puppies in terms of living habits, behaviors, and disease characteristics. Therefore, attention should be paid to scientific feeding and health management. In order for the quail species to meet the commodity specifications (400-500 g) in the current year, the stocking species required for stocking should be physically strong and have a slightly larger size, generally 150-200 g. It is also possible to adjust the size of the stocking species depending on the temperature of the farm. After being warmed in winter, the cubs can reach 200 grams in weight from April to May in the second year, while the cubs in open-air ponds need 2 to 3 years to reach this standard. At present, the extensive farming of Chengyu is mainly open-air culture. In particular, the open-air water temperature in the mid-southern region of China has stabilized at 25°C for more than 5 months. Open-air pond rearing can not only save energy, but after half a year's feeding, the color and smell of earthworms are better than those of greenhouses.
Doing a good job of cleansing and disinfecting Dianchi Lake is an important measure for health management of disease prevention and breeding, and it is also a non-negligible link for reducing the adverse pressure on the earthworms caused by the environment.
1. Small breeding pond
The area is about 200 square meters. If it is a newly built concrete pool, it must be soaked several times in the 20 days before use. In the first 6 days of stocking and breeding, Dianchi Lake should be cleaned and disinfected by first filling with water, then adding 30-50 mg/L of bleaching powder or quicklime to sterilize. Disinfecting drugs should be dissolved in a small amount of water in advance. Do not spill large chunks of medicine into the pool to prevent it from being buried in the sediment and difficult to clean. After 1 week, drain the pool water, rinse the pool wall, the bottom of the pool and the sand with fresh water, and re-inject new water.
2. Large earthen pond
An area of ​​1 to 3 acres is appropriate. The largest pool of fish and fishery should not exceed 10 acres. First, put the water in the pool and spray the quicklime evenly on the bottom soil or sand at a dosage of 50 to 100 mg/L. Then plow till it is exposed (especially for old ponds that have been used for many years). 1 week Afterwards, fill the pond with aquaculture water and press the bleaching powder evenly at a dosage of 20-30 mg/L. After 3 days, wait until the medicine disappears. In addition, it is best to remove the lush weeds from the pond for daily observation and management. In the area with gentle slopes around, clean up the gravel or hard objects above and spread evenly on a thin layer of sand. In order to facilitate healthy and safe habitat. Finally, check the perimeter of the escape guards and drain gates on the Ikei to prevent them from escaping.
