What are the conditions and how to raise loach?

Raising loach should have pond conditions and water quality conditions, and should be raised from dredging and disinfection, feed selection and daily management.

1, conditions for raising loach

Pond conditions: the area of the nursery pond is about 600 ㎝, and the depth of the pond is about 50㎝. It is best to have a soil pond, and the soil at the bottom of the pond should be compacted. Some gramineous plants (such as ryegrass and reeds) can be planted around the pond about 1㎝ from the shore for shading. Sprinkle quicklime (150Kg/ mu) on the whole pond before the seedlings enter the pond. When the water in the pond is green, the seedlings can be put in.

Water quality conditions: when raising loach, although the requirements for water source are not very high, the water source cannot be polluted. Therefore, the water quality should be clean, and the pond should be close to the water source, which is convenient for adding water later. The depth of the pond water does not need to be too much, about 40 to 50 centimeters is enough.

2. How to raise loach

Dredging and disinfection: the pond must be cleared of silt and then exposed to the sun. Generally, when loach seedlings enters tang qian for 30 days, he should bask in the sun to make the bottom of the pond look like a turtle's back, so as to eliminate the microorganisms in the pond. About a week before stocking loach fry, it can be disinfected with quicklime.

Feed selection: Misgurnus anguillicaudatus is an omnivorous fish with a wide range of feed sources. Daphnia, earthworm, maggot, etc. It is a natural food organism of loach, and rice bran, bean cake, bean dregs, blood powder and wheat bran can be fed under artificial breeding conditions. The food intake of loach is closely related to the water temperature. The daily feeding amount is 1% of the total weight of loach in March, 4% in April-June, 1% in July-August and 4%- 10% in September.

Daily management: "two precautions, two attendance, three mornings and four observations" should be achieved, that is, preventing escape and disease, patrolling the pond frequently, keeping diaries frequently, clearing the pond early, cutting materials early and stocking early (prolonging the growth period of loach), and the feed dosage should be determined according to the activities and feeding conditions of loach, weather changes, water quality changes and seasonal changes.

Morphological characteristics of loach

It is long and cylindrical with a flat and thin tail handle. Small head. Kissing skills. The lower mouth is horseshoe-shaped 5 pairs of whiskers (1 kiss whiskers, 2 pairs of maxillary whiskers and 2 pairs of mandibular whiskers). The eyes are small, on the side, covered by skin membrane, and there are no lower thorns. The branchial foramen is small, and the branchial fissure stops at the base of pectoral fin. Scales are very small and deeply embedded in the skin. Side line complete. The lateral line scale is greater than 150. The swim bladder is small and wrapped in a hard bone capsule. The dorsal fin is short, the starting point is opposite to the ventral fin, and there are no branch fins 2 and 7.

The pectoral fin is far from the ventral fin, and there is no branching fin 1, but there is branching fin 10. The ventral fin is less than the gluteal fin, and there is no branching fin 1, and the branching fin is 5-6. Whether the gluteal fin has branch fin 2 and branch fin 5. The caudal fin is round.

The upper part of the body is taupe, the lower part is white and there are irregular black spots on the side. There are also spots on the dorsal fin and caudal fin. There is a prominent black spot above the root of caudal fin. Other fins are grayish white.
