Ecological Culture technique of Loach

The ecological culture of Loach mainly includes rice field, mushroom field, water chestnut field, Zizania caduciflora field, lotus root field and so on. These fields are rich in natural bait, at the same time, crops are also good shades, and the depth of paddy fields is also consistent with the growth of Loach. Generally, 0.2 kilograms of Loach species can be released on each square meter of water surface, and 0.5 kilograms of adult Loach can be collected after half a year. It is suitable for both crops and Loach.

Finishing field block

The fields selected for raising Loach require adequate water supply. Before releasing Loach, widen and tamp the ridge of the field, insert cement board or plastic board around the field, and put in 30 centimeters of mud to prevent escape. At the same time, a trench is opened along the ridge of the field, and the vertical and horizontal box trenches are excavated in the center of the field. The ditch is connected with the chamber ditch, with a width of 50 cm and a depth of 25 cm. The breeding field can be divided into 4 equal small pieces, and the inlet and drain can be blocked with barbed wire or plastic net to prevent the Loach from escaping.

Apply sufficient base fertilizer

Misgurnus anguillicaudatus mainly preys on water fleas, water silk earthworms, Chironomus larvae and so on. Appropriate fertilization can make food organisms grow. First let the pool water dry, expose it to the sun for 4 days, and then sprinkle 130 kilograms of rice bran per mu. The next day, 200 kilograms of fermented animal manure was applied per mu, and then dried for 4 days to decompose, and then store water.

Stocking seedlings

Loach should be released in time after sowing crops in paddy field. The Loach species of about 3 cm are selected, and the stocking capacity is 20, 000-25000 fish per mu. If there is a running water environment or a higher level of feeding and management, you can appropriate more stocking.

Bait management

Misgurnus anguillicaudatus is an omnivorous fish. in addition to fertilization, it should also be fed with fly maggots, silkworm pupae, earthworms, clam meat and bean dregs, wheat bran, rice bran, bean cakes and other animal and plant feeds. To achieve quality, timing, cover, fixed point. In general, the water temperature is below 20 degrees; 70-80% plant feed accounts for 20 ~ 25 degrees, animal and plant feed is half of each other; when 25 ~ 30 degrees, animal feed should account for 60% and 70%. The Loach should be fed with a mixture of silkworm pupa and fried rice bran in the first month after seeding, and it should be put in at one time at about 5 o'clock in the afternoon every day. The amount of feeding should be slightly more than that of the next morning, and each time it accounts for about 3% of the total weight of Loach. When the water temperature is high, the amount of feeding can be increased accordingly. After a month of stocking, 15 kg / 100 square meters of animal manure should be applied every 15 days, and animal and plant bait should be fed at the same time; in the later stage, it is best to apply fertilizer and bait in the fish pit or box ditch to facilitate centralized fishing.
