1. Jianchi Pond shall be constructed with a leeward sun, adequate water sources, convenient drainage and irrigation, and no water pollution. The pond area shall be 100 square meters to 150 square meters, and is preferably divided into several small pools so as to divide the pool according to specifications. Feeding for easy management and prevention of disease transmission. The depth of the pool is generally 1 meter to 1.2 meters. Drain outlets are set at a distance of 30 cm from the bottom of the pool, and anti-escape facilities are installed at the same time. It should be noted that a plastic shed needs to be built in the winter to make the muddy winter in the shed.
Second, make preparations for stocking before they should do a good job in preparation: into the 20 cm thick mud, 10 to 15 days before the stocking of Dianchi for disinfection. One week after disinfection, add water 20 centimeters to 30 centimeters and put it into livestock manure. The dosage is 0.3 to 0.5 kilograms per square meter. Add water 40 cm to 50 cm. Put the loach into the water several days later when the water is yellow-green and the transparency is 15 cm to 25 cm.
Third, put the mud to wait for the above "everything is ready" after the stocking mud. When stocking is to be done: First of all, choose a healthy, disease-free, lively stocking. Secondly, the specifications of the mud in each pool should be roughly the same, and they can be enough at a time, but they can also be carried with them. However, they must be immersed and sterilized before stocking (2 to 4% saline can be used for 10 minutes to 15 minutes). The density is generally about 25 kg per cubic meter of water, and the pool water can be deepened to about 90 cm with increasing stocking and weight gain.
Fourth, strong management should strengthen the feeding and management of the mud in the holding pool.
1. Feed feeding loach food is omnivorous, natural feed has small crustaceans, aquatic insects, snails, cockroaches, animal organs, algae, rice bran, bean dregs, leaves, etc., feeding should pay attention to the rational mix of animal and plant foods, vote Bait should be qualitative, positioning, timing, quantitative, and the water temperature is higher than 30 °C or less than 10 °C can not feed.
2. Fertilizer in the feeding process should pay attention to fertilization, generally every 4 days to 5 days to the pool of water to soak manure once, the amount of 50 grams per square meter to 100 grams, to maintain water transparency of 15 cm to 25 cm.
3. Change the new water and pay attention to change the new water, generally change the water every 7 days 2 times, each time for 30 cm, with water quality deterioration, causing muddy floating head.
4. Disease prevention often patrols the pool, cleaning the food field once a day, bleaching powder spill every 10 days to 15 days, in order to do a good job of preventing disease, to prevent death, and to avoid death due to illness.
