1. How to breed red worms?

1. Related information about red worms

1. Distribution of red worms

Red worms generally refer to blood worms, also known as chironomid larvae. They have a worm-like body and a dark red body color. They have a wide distribution range and can be seen in basically all kinds of water bodies, and their distribution numbers are very large.

2. The value of red worms

Red worms are rich in nutrients, including protein, fat, calories, etc., and can be used as natural bait for economic aquatic animals. Moreover, red worms are of appropriate size, have good palatability, and are nutritionally comprehensive, which can promote the growth and development of fish. Red worms will also ingest organic debris in the breeding pond, which not only does not pollute the water body, but also has a certain leech purification effect. Red worms can also accelerate the circulation of water substances and can eliminate organic pollution to a certain extent. In addition, red worms are also used as excellent indicator organisms for monitoring water environment and pollution conditions.

3. Red worm price

Generally, the price of red worms of different specifications, grades and seasons is different, and the price of male red worms is higher than that of female worms. Usually the retail price of male worms ranges from 30-100 yuan/jin, while the female worms are relatively cheaper, ranging from more than ten yuan to 20-30 yuan/jin.

2. What are the profits and prospects of red worms?

1. The prospects of breeding red worms

Blood worms have a wide range of uses, whether they are used as bait for aquatic animals, for purifying water, or for testing water conditions. Moreover, as more aquatic organisms have been farmed in recent years, the demand for red worms has also increased, so the prospects for breeding are still promising.

2. Profits from breeding red worms

Generally, each acre can produce 150 kilograms of red worms per batch, and a batch can be harvested every 10 days or so. The profit per acre in a year can reach more than 50,000 yuan.

3. How to raise red worms?

The difficulty of breeding red worms is not great, but if you want to obtain high quality and high efficiency, you must master the following points:

1. The red worm breeding pond should choose a paddy field with sufficient water source and convenient irrigation and drainage as the breeding base, or choose a place with sufficient water source to convert dry land into paddy field; then prepare a silt cement pool rich in organic matter with a depth of about 50 cm and a water depth of 20-30 cm as the red worm breeding pond.

2. The introduction and inoculation of red worms are very simple, and the best time is spring and summer. Just sprinkle the collected red worms evenly in the cultivation pool. Remember to sprinkle fermented organic fertilizer into the pool water regularly in spring every year to keep the pool water fertile.

3. During the growth period, organic fertilizer should be sprinkled regularly or land grass should be directly added to allow the land grass to rot and ferment in the water. In summer, when the light and temperature are strong, the water in the pool should be appropriately increased, or a sunshade, grape rack, etc. should be built above the breeding pool.

4. Since bloodworms mainly feed on organic debris in the mud, and especially like sweet and sour bait, agricultural and sideline product waste, well-rotted organic fertilizer, etc. are good baits for them; generally, they are fed once every three days during the peak production period, and the amount of feeding is determined by the number of bloodworms in the breeding pond. In addition, water discharge should be stopped half an hour before and after feeding to avoid the loss of manure and other wastes. In addition, it should be noted that the feeding of each bait should be determined by the expected yield and the amount of remaining bait in the field.

2. What conditions are needed to breed red worms?

A: 1. Breeding conditions

1. Red worms prefer to live in micro-flowing fertile water, so this condition must be met during artificial breeding. Generally, in late spring and early autumn every year, it is the season when red worms reproduce in large numbers. At this time, red worms will float on the water surface, causing the water surface to be brown-red, and they need to be collected in containers.

2. If it is a small-scale breeding, you can take back the bottom silt and red worms together, put them in a glass container, and then use natural water for breeding. If you use tap water for breeding, you need to expose the tap water to the sun for 2-3 days first.

3. When raising fish, you need to change the water once a day, and take anti-cold measures when the temperature is low. You can cover the container with a red wet towel to keep it moist. The container needs to be large-diameter so that the red worms will float to the surface to breathe. If the container mouth is relatively small, they will easily die.

2. Control the light source. The light source is very important for breeding red worms, because red worms cannot live without light, so the lights must not be turned off at night. If there is no light source at night, the red worms will be too lazy to breathe and easily die. Generally, a 5-watt small bulb can be used as a light source at night.

3. Water quality control

1. The water depth should be 3-5cm. When breeding in spring, the water level can be slightly shallower during the day to increase the water temperature, and the water level can be appropriately deepened at night to help keep warm and prevent cold.

2. Red worms prefer micro-flow water environment. If the water flow is too strong, it will take away the nutrients and eggs on the culture medium. It will also consume a lot of the red worms' physical strength, which is not conducive to increasing production.

3. If the water flow is too small, it will not be conducive to the discharge of water and excrement, which will easily lead to deterioration of water quality and cause death. According to practical production, a water flow of 5-10 liters per second is the best water flow environment.

4. At the same time, red worms are sensitive to pesticides and harmful substances. Pay attention to this when managing water quality. Do not use water that has been sprayed with pesticides and industrial wastewater.

4. Feeding

1. Red worms mainly feed on organic debris in the soil and are very fond of sweet and sour bait. Poultry manure, domestic sewage, etc. are all baits for red worms. Generally, in professional farms, rice bran, sawdust, silt, pigeon manure and other raw materials are fermented to make feed. If it is a family farm, you can use yeast powder to soak in water and feed it.

2. Feeding is also a key point in red worm production. Feeding in small amounts and multiple times can increase production. Generally, feed once every 3-4 days, with 50-100kg of manure per mu each time. Mix it with water and sprinkle it throughout the pond.

3. When feeding, pay attention to the amount of leftover bait and do not feed too much blindly to prevent excessive organic matter in the water body, which will cause fermentation and produce toxic substances, affecting the production of red worms in the later stage.

3. Can rainwater be used to raise red worms?

Can

1. During the breeding process, the temperature should be controlled below 26 degrees Celsius to avoid direct sunlight.

2. Control humidity. The red worms should not be too wet or too dry. A sprinkler can be installed above the farm to cool down and adjust the humidity of the site when the temperature is too high. Drainage ditches should also be built to prevent rainwater from accumulating in the breeding site and causing red worm losses.

3. Prevent escape. In the rainy season, red worms will escape with the water flow. When building a breeding site, cement stalks can be used around the farm to prevent the red worms from escaping.

4. How to raise red worms in a pond? What are the conditions? Can teachers help answer this?

First, it must be raised in running water, not in living water;

Second, the temperature should be below 26°;

Third, there are aquatic plants growing in the place where red worms are raised;

Fourth, keep it in the shade of the pond.

5. How to breed and reproduce red worms?

Red worms grow best in fertile water with steady water flow. When breeding red worms artificially, you need to build a cement pond with an area of ​​10-50 square meters. The depth of the water layer in the pond should be kept between 3-5 centimeters, and the bottom of the cement pond should be covered with silt rich in organic matter.

6. How to breed red worms?

Outdoor farming method:

Cement pools or earth pits can be used. Generally, the pool is 1m deep and 10-30m in area. Use bleaching powder or quicklime 10ppm to dry clean the pond, expose it to the sun for 7 days, add 0.5m deep water, and then expose it to the sun for another 7-15 days before fertilizing. Put horse manure or other animal manure 1.5kg/m3 in the cement pool as base fertilizer.

The amount of fertilizer applied to the earthen pond is 4kg/m3, with horse manure or other animal manure and 1.5kg of non-toxic plant stems and leaves such as straw as basal fertilizer. The purpose of basal fertilizer application is to promote the massive reproduction of algae in the water body and provide the necessary material basis for the growth and reproduction of Daphnia.

Catch Daphnia from ponds or small rivers, wash and disinfect them, and then put them into the pond. When the water temperature is 18℃-25℃, Daphnia will begin to reproduce in large quantities after about 3-4 days. Catch them every 1-2 days, and catch about 10%-20% each time. After several catchings, if the amount of Daphnia decreases, stop catching, add new water immediately, and apply appropriate amount of topdressing. The amount of topdressing should be adjusted appropriately according to the changes in water color and weather.

Normally, the pond water should be yellow-brown and the water transparency should be maintained at about 30cm. If the water is too clear, more fertilizer should be applied. If the water is dark brown or black-brown, less fertilizer or no fertilizer should be applied. When applying topdressing, multiple fertilizers should be used crosswise (manure, ammonia fertilizer, nitrogen fertilizer, phosphate fertilizer, etc.), and do not use a single fertilizer, so as to maintain a dynamic balance of various elements in the water.

Indoor cultivation method:

Indoor cultivation is less affected by weather changes and the cultivation conditions are easier to control. The disadvantage is that it can only be produced in small quantities. Wooden barrels, glass jars and other containers that can hold a certain volume of water can be used as cultivation equipment. When cultivating, first inject clean water (natural water or tap water) into the culture container, expose it to the sun for 3-4 days, and add 1.5kg/L of fresh horse manure, 20g of fertile soil, and 2g of straw or stems and leaves of other non-toxic plants.

Manure and soil can be added directly. Cut grass into pieces and boil them before adding. Then stir with a wooden stick and let it stand for 2 days. Finally, introduce the seeds. 8-12 per liter is appropriate. After 3-4 days, Daphnia will begin to multiply in large numbers. Fertilize every 5-6 days according to the fertility of the water.

7. How much does it cost to raise red worms per acre?

Site cost Bloodworm breeding ponds are usually built with bricks, and the bottom is smoothed with cement mortar. The pond is rectangular, preferably small rather than large, and 40 cm high. The site reconstruction fee is generally 30,000 yuan/mu, but from the second year onwards, there is no need for site reconstruction fees, which means that the breeding cost will be at least 30,000 yuan/mu less from the second year onwards. Seedling cost There are two main ways to obtain bloodworm seedlings. One is to collect wild bloodworms in the wild by yourself, which has the advantage of low cost.

8. Red worm farming?

Environmental requirements: Before breeding red worms, friends should understand their living environment. Red worms like a cool and humid environment, but light is a must. In addition, the breeding density per unit area must be controlled, otherwise they will die easily.
