1. How to raise loaches in lotus root fields?

When raising loaches in lotus root fields, you should pay attention to the following points:

1. Raising loaches in lotus fields

Raising loaches in lotus fields is an efficient ecological breeding method, with an average yield of more than 150-200 kg of loaches per mu. Any lotus field with a low water level and a thin silt layer can be used to raise loaches.

1. Renovation of lotus field. Dig a circular fish ditch 2.5-3 meters wide and 1-1.2 meters deep around the field, and set up a fish pond at each of the two or four corners. Use the excavated soil to build a 1-meter slope ridge. Cover the slope and the circular fish ditch around it with a white nylon net or polyethylene net of more than 30 meshes. Both ends and the joints should be buried in the soil, or wooden boards and calcium plastic boards (30 cm into the mud) should be inserted around it. Two nets should be built for the injection and drainage outlets, with polyethylene nets on the outside and metal nets on the inside to prevent the loaches from escaping.

2. Release loach seeds. Before stocking, drain the field, expose to the sun for 3-4 days, and then spread 130 kg of rice bran per mu. The next day, apply 250 kg of livestock manure per mu and expose to the sun for 4-5 days. Then store water to plant lotus roots. One week after planting lotus roots, release 80-100 kg of healthy loach seeds weighing 10-15 grams per mu of lotus field. Wild loach seeds that are not injured and caught in cages can be used, and they are of the same size. Before stocking, disinfect the lotus field with 20 grams of bleaching powder per cubic meter of water, and soak the loach seeds in 3% salt water for 3-5 minutes before stocking to improve the survival rate of loach.

3. Daily management. Feed twice a day, 70% at 6:00-7:00 in the morning and 30% at 1:00 in the afternoon. When the water temperature is 15℃, the daily feeding amount is 2% of the loach's body weight. As the water temperature rises, the feeding amount increases, and the maximum feeding amount can reach 10% of the fish's body weight. When the water temperature is below 10℃, feed or stop feeding. In the first month after stocking, a mixed bait of half silkworm pupae and half fried rice bran should be fed. Once a day, the feeding amount is 3-4% of the total body weight of the loach each time. After one month, apply organic fertilizer mainly composed of animal manure once every 15 days, and the amount of topdressing per mu each time is 100 kg. At the same time, feed silkworm pupae, rice bran, bean cake, vegetable cake, animal scraps and other baits. In the later stage, it is best to fertilize and feed in the fish gathering pit to facilitate centralized capture. Check the embankment facilities regularly. If there are loopholes, broken nets and collapses, they should be blocked and repaired immediately to prevent birds, rats, snakes and other predators. Generally, change the water once a month and add appropriate amount of quicklime or bleaching powder.

2. How many loaches can be raised in one acre of land? What is the benefit of raising loaches in one acre of land?

How many loaches can be raised in one acre of land, and what is the benefit of raising loaches in one acre of land? It should not be a problem to raise 700 to 900 kilograms of loaches for sale in one acre of land. The wholesale price is calculated at the lowest 15 yuan, and after deducting the cost, there is still several thousand yuan. If you raise three or five acres of mixed loaches of different sizes, how much money will you make in three to five years? This account is hard to calculate.

One acre of land can produce 1,000 kilograms of loaches. The profit depends on the price you sell them at.

3. How to raise loaches in the fields

Yes. This technology has been around for a long time, but it is a bit troublesome. The main problem is that when applying fertilizers and pesticides to the fields, in order to avoid poisoning the loaches, the loaches have to be concentrated and put back two or three days after the fertilizer is applied. In addition, ordinary rice fields must be specially adjusted, such as making fish ponds and fish ditches, before loaches can be raised in the fields.
