Cultivation techniques of loach

1, construction of loach pond. The loach pond used has an area of 50 ~ 80m2 and a depth of1~1.5m. The loach pond can be made of brick, stone and other materials, and the top of the wall is provided with a pressure mouth, which extends into the pond for 5 ~ 6cm. There is a drain pipe in the center of the bottom of the pool, with a diameter of about 1.5cm, and an overflow port of 1 at the edge of the pool to control the water level.

The outlet and overflow should be covered with barbed wire to prevent the 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 reduce the water temperature. In addition, some climbing plants such as grapes or loofah can be planted around the loach pond, which can provide a shade for loach in summer.

2, fried stockings. 7 ~ 10 days before stocking loach fry, thoroughly clean the pond with 0.2kg/ m2 quicklime; After 5 ~ 7 days, the water is stored at 10 ~ 20 cm, and the mixture of organic fertilizer and inorganic fertilizer at 10 ~ 15kg/ mu is applied to cultivate the basic bait organisms in the water.

3. Feed feeding. Misgurnus anguillicaudatus is a small omnivorous fish with a wide range of feed sources. Daphnia, earthworm, fly maggot, etc. It is a natural food organism of loach, which can be fed with rice bran, bean cake, bean dregs, blood powder, wheat bran and so on. Under the condition of artificial reproduction. The food intake of loach is closely related to the water temperature.

The feeding method is to build a feeding platform in the loach pond and put the feed on the feeding platform. Feed should be fresh, pollution-free, non-rotting and non-deteriorating. The feeding time is usually around 9: 00 am, and the feeding amount is subject to the loach eating within 3 ~ 4 hours.

4. Water quality control. When loach species first entered the pond, the water depth of the pond was kept at10 ~ 20 cm; In the future, with the growth of loach species, the water level will be gradually deepened to the due depth, which is shallow at ordinary times and deep when it is hot and hot, and new water will be injected frequently to maintain a good water environment.

Precautions:

1. Daily management should be "two defenses, two attendance, three mornings and four observations", that is, escape prevention and disease prevention; Be diligent in patrolling the pond and keeping a diary; Clear the pond early, eat early, and purchase early. According to the activity and feeding situation of loach, weather change, water quality change and seasonal change, the feed feeding amount is determined.

2. Disease control. Strive to achieve disease-free early prevention and early treatment of diseases. Spraying quicklime and bleaching powder regularly in the whole pond can improve water quality and prevent fish diseases. It is necessary to promptly remove water snakes, water rats and other harmful organisms in the loach pond.

3. In late autumn and early winter, when the water temperature drops to 10 ~ 15℃, the food intake of loach decreases and it can be fished. Generally, the method of draining pond water for manual capture is adopted.
