What are the risks of raising earthworms at home? Is it difficult to sell them?

The risks in the aquaculture industry mainly come from two aspects.

1) Disease. Earthworms are prone to disease, so the temperature and humidity must be properly controlled before planting.

2) Market. The market determines the market situation. Earthworm farming is no longer a profitable business as it was a few years ago. More and more earthworms are entering the market, causing prices to fluctuate. Farmers have both gains and losses. Learning to fight price wars is a must. In addition, the most important thing is sales. Sales are the most direct factor that restricts whether farmers can develop. Without sales, there is no profit to talk about. Farmers must not only be good technicians, but also learn how to do business.

Feeding and management

1. Feed: Earthworms are omnivorous animals. Animal feed includes earthworms, crickets, mole crickets and various animal scraps; plant feed includes wheat bran, rice bran, cake meal, flour residue, tofu dregs, corn, broken rice, green vegetable leaves, cabbage leaves, pumpkin flowers, mulberry leaves, melon and fruit peels, etc.

2. Water supply: In summer, several small water basins should be set up in the breeding pond for earthworms to drink water, and water should be sprinkled into the pond frequently. The pond should also be avoided from being dry for a long time during hibernation. When feeding semi-dry and wet feeds, the pond should be kept moist in spring and autumn (the humidity of the breeding soil should be 20%).

3. In winter, choose garbage mud, garden soil, ditch mud, stove soil, sandy soil, loam, etc. that are rich in humus, loose and fertile, and mix them with 20% to 30% chicken manure, pig manure, charred mud ash or plant ash, etc., and expose them to the sun. The depth of the breeding soil in the pond is: 7 cm to 10 cm for 1-4 years old, 16 cm to 20 cm for 5-8 years old, and 20 cm to 26 cm for nymphs and adults above 9 years old.

4. Temperature and humidity The suitable environment temperature for earthworms is 25℃～30℃. They start to move and forage when the temperature is above 10℃, hibernate in the soil when the temperature is below 10℃, and die when the temperature is -5℃. Therefore, some straw, chicken feathers and other warm things should be put in the pond in winter, and they should be cleared out in time during the foraging period of the following year. The relative humidity should be 75%～80%.

5. To prevent poisoning, it is strictly forbidden to place and use pesticides and fertilizers within 100 meters around the pool.

6. Divide the larvae and mother earthworms at the right time. During the breeding process, the mother earthworms often eat the larvae and eggs. Therefore, when the larvae can move and forage on their own (referring to nymphs over 5 years old), the mother earthworms should be placed in another pond in time. At the same time, the larvae should also be raised in different stages.

7. The stocking density per square meter can support 1.5 kg of adults, 0.15 kg to 0.5 kg of 1st to 3rd instar nymphs, 0.6 kg to 1.2 kg of 4th to 6th instar nymphs, and 0.6 kg to 0.9 kg of nymphs over 6th instar.

8. Feeding young nymphs mainly refers to 1st to 4th instar nymphs. They are small and weak, so they should be fed with concentrated feed. You can spread the feed evenly on the surface of the feed soil, then use your hands to dig about 2 cm deep into the central soil and rake the soil. Mix the feed into the surface layer of the soil, and take care to prevent it from escaping.

9. Prevent pests and natural enemies

(1) Ants: Dig a trench around the pond and fill it with water, or apply tung oil, sticky substances, etc. on the pond wall.

(2) Mites: First, use roasted fine feed to attract and remove mites during the day; second, change the breeding soil; third, use chemical control, that is, use 5 grams of dichlorodiphenyltrichloroethane, 50 grams of quicklime, 50 grams of chimney ash, and 2.5 liters of hot water per cubic meter of soil, dissolve, filter, and remove the residue, and then spray evenly on the breeding soil where the insects have been screened out, once a day for 5 consecutive days.

(3) Rats, cats, weasels, chickens, ducks, frogs, snakes, spiders, etc. are all natural enemies of earthworms. Preventive measures such as adding iron mesh covers and sealing should be taken.

10. Disease prevention and treatment

(1) Big Belly Disease: The abdomen of the diseased insect is swollen and shiny, the head becomes pointed, and the feces are watery. Prevention and control measures: Control the moisture content in the soil to no more than 10% during the larval stage, alternate dry and wet feed, and adjust the soil humidity according to growth needs during the middle and adult stages.

(2) Fungal infection: The insects have a dull surface, a dark green abdomen with spots, a thin body, do not eat at night, and die upon emerging from the soil during the day.

Prevention and control measures: First, replace the loose soil in the pond and spray the insects with 0.5% Fuhanqingermalin liquid to sterilize; second, grind 1 tablet of 0.25g tetracycline into powder, mix with 0.25kg of powder concentrate, feed for 2-3 days and the disease will be cured. From September to October every year, collect the 8-10-year-old female nymphs and adults and male nymphs (collected when the males are removed at the 6th instar), first, put them in a container and scald them to death, then wash them with clean water and place them on bamboo curtains or flat plates to dry;

The second is to put it in an iron pot to dry, or put it in a 50℃ oven to dry and then sell it for medicine. Dried earthworms should be stored in boxes or jars with lime blocks and sealed tightly.

If there is no sales channel, it is useless to raise eggplants and sell them. Therefore, before raising them, you should first understand the sales market of eggplant molds and see what the market is like.

1. You need start-up capital, a site, technology, and investment. It is easy to get sick, so pay special attention to its resistance to drought. The temperature and humidity of the Changlian must be well controlled.

2. For sales, you can find a larger company to cooperate with. Generally, you can contact them through the Internet or a third party. There are too many people dealing with earth yuan now. The profit margin of Huanxian is not as high as before.

I want to cooperate with you, how about it? I am also a novice, let's discuss it together: Q: 985878363

How much money can be earned from small-scale breeding of earthworms in a year?

The profit of raising earthworms is about 1:3.
