The techniques for cultivating loach should be as follows:

1. Construction of loach pond

The loach pond should be located on a relatively flat terrain, with good ventilation and sunshine, and good water inflow and drainage. Convenient and easy-to-manage places can have various shapes. Generally speaking, a rectangular shape with an east-west orientation is better. The area of ??loach ponds varies depending on the breeding method and level. Generally speaking, the area of ??loach ponds used for courtyard breeding is 50 square meters to 80 square meters, and the pond depth is 1m to 1.5m. The loach pond can be built with bricks, stones and other materials. There is a pressure port on the top of the wall, which extends 5cm to 6cm into the pool. There is a drainage outlet in the center of the bottom of the pool. The diameter of the water pipe is about 1.5cm. At the same time, there is an overflow outlet on the edge of the pool to control the water level. The water outlet and overflow should be covered with wire mesh to prevent seedlings from escaping. Some aquatic plants, such as water peanuts and water hyacinths, can be planted in the loach pond to improve the water environment and lower the water temperature. In addition, some climbing plants such as grapes or loofahs can also be planted around the loach pond to provide loach with shade and coolness in summer.

2. Stocking of seedlings

7 days to 10 days before stocking loach seeds, use 0.2kg/square meter of quicklime to thoroughly clear the pond; after 5 to 7 days, store 10cm of water 20cm, apply a mixture of organic fertilizer and inorganic fertilizer at 10kg/acre to 15kg/acre to cultivate basic feed organisms in the water body. Stocking loach species require neat specifications, strong physique, rich muscles, no disease or injury, and bright color. The stocking density should be determined according to the pond conditions, feed sources, and management level. Generally speaking, the specifications are 5cm to 7cm in length. The stocking density of loach species is 80/square meter to 100 fish/square meter. At the same time, 5 to 8 fish/square meter of crucian carp can be stocked in the loach pond.

3. Feeding

Loach is an omnivorous small fish with a wide range of feed sources. Water fleas, earthworms, fly maggots, etc. are the natural food organisms of loach. In artificial breeding, Under certain conditions, rice bran, bean cake, bean dregs, blood meal, wheat bran, etc. can be fed. The food intake of loach is closely related to the water temperature. The daily feeding amount in March is 1% of the total weight of the loach, the daily feeding amount from April to June is 4% of the total weight of the loach, and the daily feeding amount from July to August The daily feeding amount from September to October is 4% of the total weight of the loach. The feeding method is to build a feed table in the loach pond and put the feed on the feed table. The feed must be fresh, non-polluted, non-rotted, and non-deteriorated. The feeding time is generally around 9 a.m., and the feeding amount is based on the loach’s 3 It shall be eaten within 4 hours to 4 hours. During the adult stage of the loach, the amount of feed should be adjusted appropriately according to weather conditions and the growth and feeding conditions of the loach. Remaining bait should be removed promptly.

IV. Water quality control

When the loach species first enter the pond, the depth of the pond water is kept at 10cm~20cm; later, as the loach species grows, the water level will gradually deepen to the appropriate depth. It should be shallower at ordinary times, but can be deeper when it is hot and hot, and new water should be injected frequently to maintain a good water environment. When the weather is hot and muggy, the pool water is prone to lack of oxygen. If a loach is found swimming to the surface and spitting out air, new water should be added in time or oxygenation measures should be taken.

5. Daily management

It is necessary to achieve "two precautions, two diligence, three mornings, and four checks", that is: prevention of escape, disease prevention; diligent pond patrol, and diligent diary keeping ; Clean the pond early, start feeding early, and stock the loach early (extend the growth period of loach); determine the amount of feed based on loach activity and feeding conditions, weather changes, water quality changes, seasonal changes, etc.

6. Disease prevention and control

Strive to achieve early prevention in the absence of disease and early treatment of disease. Sprinkling the entire pond with quicklime and bleaching powder regularly can improve water quality and prevent the occurrence of fish diseases. Water snakes, water rats and other harmful organisms in loach ponds should be removed promptly.

7. Fishing

In late autumn and early winter, when the water temperature drops to 10°C to 15°C and the food intake of loaches decreases, fishing can be carried out. Generally, the method of draining the pool water and artificially entering the pool to capture is used.
