Pond conditions If the loach is raised until spring sales, choose an outdoor pond. The pond area is suitable for 0.6 ~ 0.7hm2, the pool depth can reach 1.2 meters, the thickness of the bottom of the pool is 20 cm, and the pool should be solid. For sales in winter, Dianchi Lake should be built indoors, such as in plastic sheds and houses. The area of ​​Dianchi Lake can range from a few square meters to several hundred square meters, with an area of ​​100 to 150 square meters and a depth of 1 to 1.2 meters. It is best to build a concrete pool. If earthen ponds are built, ponds should be compacted. In addition, the cement pool is covered with 20 cm thick soft mud at the bottom of the pool to serve as a habitat for loach. The cement pool may not be mud-laid, artificial reefs may be placed, and the method of placement may be referred to as a part of aquaculture technology. Water sources include rivers, lakes, springs, and wells. If tap water is used, it should be used outdoors for 4 to 5 days. Preparation before stocking 10 days before stocking was disinfected with quicklime, and the lime granules were hydrated into slurry. The whole pond was splashed with water. After sterilizing 0.15 kg of lime pellets per square meter for 2 days, the outdoor pond was filled with water 1 meter deep and the indoor pond water was filled with 0.6-0.8 meters deep. Mud stocking The acquisition of loach requires a physically strong, disease-free, invigorating swim. For the muddy time that is too long to be raised, it is advisable to purchase a loach with short holding time, which is usually 1 to 2 days. The loach in the pond can be filled at one time, and it can also be carried with the fish. Disinfection of the fish must be performed before stocking. Loach can be used 30 ~ 50g / l of salt water immersion fish body disinfection, time is 5 to 10 minutes. The outdoor pond is stocked with 3 to 5 kg of mud per square meter, and the indoor pond is stocked with 5 to 10 kg of mud per square meter. Daily management The outdoor ponds should always clean the snow and dust on the ice surface. If the pond leaks, it should also be filled with water. The indoor pond can keep the water surface free of ice or thin ice, change the new water every half month, change the amount of water each time by one third of the total water volume, and keep the water depth of the pool water at 0.6-0.8 meters.
