Loach is not only a delicious food with high protein and low fat, but also has medicinal properties such as blood and Qi, diuretic diuresis and so on. Not only for consumers around the country like it, but also exported to many countries and regions in the world, prices have been bullish for years.
First, seed breeding
1. broodstock selection. Muddy generally 2 winter (after 2 winters) reach sexual maturity. Sexually mature broodstock spawned in batches from April to September and was the most prosperous from May to July. When the water temperature is stable at 22 °C, choose a healthy body, no disease, no injury, more body mucus, female body length 10 cm, weight 18 grams or more, male body length 8 cm, body weight more than 12 grams of broodstock. Male and female identification methods are: female pectoral fins wide and short, the end is more round, during the breeding period by hand to gently press the abdomen with the outflow of eggs; male pectoral fin large and narrow, long tip microbend, the second fin base has a thin slice of bone During the reproductive period, there is semen outflow from the abdomen.
2. Induction hatching. Reproductive methods include natural spawning and artificial insemination. In order to increase the spawning rate and make spawning uniform, no matter which method is used, hormone injection should be used. The dose is 0.5-1 mouse carp pituitary or 100-150 international units of chorionic gonadotropin (HCG) injected into each female scorpion, and is formulated with physiological saline or distilled water to 0.1 ml, and the male halve is halved. If natural spawning, after hormone injection, male or female ratio of 1:2 or 1:3 can be placed in large water tanks or small fish ponds, or can be placed in the incubator box suspended in the pond water body using a 40-mesh sieve. A fish nest is made of brown or willow roots in the pool (box). After spawning, fish out in time to prevent the broodstock from swallowing eggs. The eggs that adhere to the fish nest naturally hatch in the original pool. If artificial insemination is used, the male and female shall be kept in the water tank or cage after the hormone injection. After 12 hours, if the females are found to automatically discharge a small amount of eggs, or if the eggs are gently pressed by the abdomen, the artificial insemination can be performed. The broodstock's eggs and sperm are squeezed into a container such as a basin in a short time, and the fertilization is fully mixed. The fertilized eggs can adhere to the fish nest and naturally hatch in the small fish pond. After 1 to 2 days (about 24°C water temperature), the seedlings can emerge.
3. Sapling cultivation. The yolk sac disappeared after 3 days of hatching from the muddy seedlings, and they were free to swim and feed. They should be transferred to nursery ponds in a timely manner (cultivation in the original tanks hatched in small ponds). 800 to 1000 tails per square meter. The area of ​​nursery ponds should not be too large, with 50 to 100 square meters being preferred. In the pool, fish should be digging and the depth of the pool should be 20-30 cm. Disinfect and clear the pond before stocking, and apply livestock organic fertilizer to cultivate food organisms. In the initial stage of stocking, only water is filled in the fish slip. After the habit of seedlings, the water is poured into the pool to the planned depth and the whole seedlings are distributed. Began to feed cooked egg yolk, fish meal, milk powder, soy milk and other fine baits. After a few days, boiled bran, corn flour, wheat flour, and vegetable leaves are used as boiled food. Animal feeds are fed. Feeding 3 to 4 times a day, the initial feeding amount is 2% to 5% of the total weight, and 8% to 10% in the later period. After being fed for about 1 month in the nursery pond, the body is as long as 3 to 4 cm and the body weight is 0.4 to 0.5 g. When the habit of drilling mud begins, the young quail can be fed into ponds, rice fields, or wooden boxes for feeding.
