In summer and autumn, a large number of loach is listed and the price is low. At this time, some muddy, disease-free and innocent muds are acquired. Ponds are used to set up cages or pools, or buckets, pots, etc. are used for muddy cultivation until New Year's Day and Spring Festival. When the price is high, it is listed and sold. The price per kilogram is generally around 5 yuan. The benefit is considerable. There are the following types of holding methods.
1, fish rod temporary raise:
A fish with a diameter of 25 cm, a bottom diameter of 65 cm, and a height of 24 cm can be placed in still water with 7-8 kg per loach. If it is raised in microfluidic water, it can store 10-15 kg. When the rod is placed in water, one third of the surface of the rod should be exposed so that the loach can breathe normally.
2, cage maintenance:
The length, width and height of the cages can be made in a ratio of 2:1:1.5. The cages should be placed in open rivers or ponds with good water quality. Holding density depends on the water temperature and the size of the mesh. Generally, it can hold 30-40 kg per square meter.
When using the above two methods to keep the loach, do diligent inspections. Once you find that the holes in the cages and cages are plugged, brush them in time to prevent the water quality in the rods and cages from becoming fresh; Pick up.
3, barrel holdings:
All kinds of barrels or plastic barrels can be kept muddy. If a 35-liter barrel is used, 5-7 kg of loach can be stocked. Holding time starts 1-2 days for changing water 4-5 times a day, changing water 2-3 times a day after the third day. Each change of water only changes about 1/3 of the water in the barrel.
4, cement pool holdings:
This method is suitable for large-scale relay bases. The site should be selected for areas with sunny leewards, abundant water sources, fresh water, and no pollution. The cement pool should have facilities such as sewage and oxygen, and it is convenient for water drainage. The cement pool is of different specifications, generally 8 meters, 4 meters, and 1 meter, and the water storage capacity is about 20 tons. In the form of flowing water, the holding density is 40-50 kilograms per square meter. If a sink-type cement pool is built, 100 kilograms of loach can be raised per cubic meter of water in the sink. Mudworm should be strictly selected before entering the cement pool. It requires strong physique, no sickness, no injury, active and lively, and the mud size in the pool should be the same. It can be put in one time, or it can be put together, but it must be used before release. % saline soak for 3-5 minutes. In addition, we must pay attention to summer sun shade above the pool to take shelter, change the water twice a day; change the water every day in the fall; change the water every two days in the winter. Each change of water volume is 1/2 of the body of water. During the holding period, feeds should be properly fed. Mud feeding is more complex, natural feed has small crustaceans, aquatic insects, snails, cockroaches, animal organs, soybeans, rice bran and so on.
