CATDOLL : CATDOLL: Red worm breeding training base (where is the red worm breeding training base)

1. High-yield breeding technology of red filarial worms?

Red worms are also known as water earthworms, red silk worms, and red nematodes. With the rapid development of the breeding industry of famous and high-quality aquatic products, red worm bait is becoming more and more popular among breeders and has high breeding value. Let's learn about the red worm breeding technology below.

1. Breeding value

Bloodworms reproduce quickly and have high nutritional value. The dry matter contains 62% crude protein, 35% essential amino acids, and 98% nitrogen recovery rate. They are the preferred bait for many aquatic animals during the seedling stage, and are the main food for benthic fish such as sturgeon, mandarin fish, carp, crucian carp, loach, giant salamander, and eel. The species of bloodworms suitable for breeding include Su's tail gill earthworm and Ho's water earthworm. Raising bloodworms well can provide long-term, stable, high-quality animal feed for aquatic products, reduce breeding costs, and improve breeding efficiency and quality.

2. Selecting and cultivating fields

1. For red worm breeding, it is advisable to select paddy fields with sufficient water sources and convenient irrigation and drainage as breeding bases, or to select places with sufficient water sources to convert dry fields into paddy fields. General paddy fields do not need to be transformed, as long as the ridges do not leak and are not washed away in rainy days. The slope of the paddy field is required to be 0.5-1%, with an inlet at the higher end and a drain at the lower end, and fences at the inlet and drain to prevent fish, shrimp and other harmful organisms from entering.

2. Dig a circular ditch along the edge of the ridge in the insect field so that the water in the side field can be drained. The culture medium should be raked flat to make the culture medium flooded to a uniform depth, and the inlet and outlet should be set reasonably to avoid dead corners without water circulation in the insect field. The distance between the inlet and outlet should be far enough to prevent the feed, fertilizer, etc. from being carried away by the water flow.

3. In order to reduce costs, organic sludge and manure are generally selected. The procedure for filling the culture medium is to first lay a layer of sludge with a thickness of 5 to 10 cm. If the sludge in the selected field is thicker, this process can be skipped. Then apply 5 to 10 kg/m2 of human or livestock and poultry manure on the surface, and rake the surface of the culture medium flat.

3. Introduction and inoculation

1. Introduction: In the south, introduction and inoculation can be carried out all year round, but spring and summer are the best time for inoculation. There is no shortage of bloodworms in all parts of the country. Natural bloodworms are abundant in drainage ditches in the suburbs of towns, wastewater pits in livestock and poultry farms and slaughterhouses, and sewage ditches where leather factories, sugar factories, and food factories discharge waste. Seeds can be collected nearby. The collected seeds can be transported back together with sludge and waste residues, because they contain a large number of worm eggs, and they should be inoculated immediately after being transported back.

2. Inoculation: The inoculation work is relatively simple. Before inoculation, cut off the water inlet and outlet, keep 2-3 cm of water in the field, and then evenly sprinkle the collected insect seeds on the surface of the culture medium, inoculating about 500 grams per square meter. After one hour, when the red worms drill into the mud and resume water flow, the inoculation is over.

4. Feeding

1. Bait: Red worms mainly feed on organic decaying debris in mud, and they especially like to eat sweet and sour bait. Livestock and poultry manure, domestic sewage, and waste from agricultural and sideline products processing are their main sources of bait. Some materials say that the manure should be fully fermented first, otherwise the manure will ferment in the pool and produce high heat to burn the worms. But in actual production, manure can be directly fed to red worms without going through the fermentation process, and the growth of red worms is better. Because many nutrients in the fermented manure are converted into water and inorganic salts, red worms cannot use these inorganic salts as a source of nutrition, so they grow weakly and the production cost is high. However, fermented manure also has its advantages. It produces fewer maggots, harmful bacteria and parasite eggs, and has less odor in the field. Producers can comprehensively consider and choose the production method they need.

2. Feeding: Feeding is an important part of the breeding process. Feeding in small amounts and multiple times helps to achieve high yields. During the peak production period, feed once every three days or so, and add 50 to 100 kg of manure per mu each time. Mix it with water to make a paste and sprinkle it all over the pond. Water should be stopped from half an hour before feeding to avoid manure loss. Feeding should follow the principle of feeding more when the temperature is high and less when the temperature is low. The amount of feed should also be adjusted according to the expected yield. Daily management should pay close attention to the amount of remaining bait in the field. Do not blindly feed more to achieve high yields. Too much organic matter accumulation in the field will produce a large amount of harmful substances due to fermentation, inhibiting the growth and reproduction of maggots and seriously affecting the yield.

5. Water quality control

It is more appropriate to control the water depth at about 3 cm. In fine weather in early spring, the water can be shallower during the day to facilitate the water temperature to rise, and it can be appropriately deepened at night to facilitate heat preservation and anti-freeze. Too much water flow will not only take away the nutrients and eggs on the culture surface, but also increase the energy consumption of the red worms themselves, which is not conducive to increasing production. Too small a flow rate or even a long period of static water is not conducive to the supply of dissolved oxygen and the discharge of harmful substances such as metabolic waste, which will lead to deterioration of water quality and mass death of red worms. Practice has shown that a flow rate of 5 to 10 liters of water per second per acre of breeding field is sufficient. Red worms are very sensitive to harmful substances such as pesticides in water. Industrial wastewater, field water that has just been sprayed with pesticides, or medicated water for treating fish diseases cannot be used.

6. Pounding and drying the fields

1. Pounding the field: Pounding the field means carefully turning over the culture medium in the field every 10 to 15 days. The specific method is to use a "丁"-shaped wooden rake to stir the culture medium after draining the field, and consciously turn moss, weeds, etc. into the mud or pull out the weeds. First, it can prevent the culture medium from hardening, second, it can drive away the metabolic waste of red worms and harmful gases produced by the decomposition of manure, third, it can effectively inhibit the growth of duckweed and weeds, and fourth, it is conducive to the smooth flow of water. The number of pounding the field can be reduced in seasons with lower temperatures.

2. Sun drying: Sun drying is to drain the water in the field on sunny days and expose the culture medium to the sun for a few days. When the temperature is high, it is exposed to the sun for 3 to 4 days, and the time can be appropriately extended when the temperature is low. When the field is sun-dried, the red worms drill into the mud. As long as the culture medium does not dry out and crack, they will not die. On the contrary, due to the high temperature of the culture medium, the red worms grow faster and lay a large number of eggs. In the absence of water flow, the eggs laid are not carried away by the water, thus hatching a large number of young earthworms. From many cases of failed breeding, it can be found that although a large amount of bait is fed, the yield of red worms is extremely low, and there is a large amount of moss, duckweed, and miscellaneous fish in the worm field, which can be almost impossible to remove. The reason lies in the lack of the field drying link. Therefore, it can be said that field drying can kill two birds with one stone, breeding a large number of larvae and removing enemies, which is the key to high yield.

7. Harvesting and Purification

1. Harvesting: Red worms have a strong reproductive capacity. The hatched young earthworms enter the peak reproductive period after the 30th day, and can produce 1 million to 4 million eggs in their lifetime. However, the life span of red worms is not long, generally only about 80 days, and a few can live up to 120 days. Therefore, timely harvesting is also an important measure to obtain high yields. Cut off water or reduce water flow on the night before harvesting, causing hypoxia in the field. When the sky begins to lighten the next morning, use a small net made of polyethylene mesh to scoop up the earthworm mass in the water. The amount of harvest each time is based on the scooping of the worm mass on the culture surface. Such a harvest will neither affect the reproductive capacity of the group nor reduce the yield due to individual aging and death due to untimely harvesting. After harvesting, you can start draining the accumulated water in the field, then apply manure, and then carry out the processes of threshing the field and drying the field.

2. Purification: To purify the red worms, pour the muddy red worms into the filter cloth and wash them in water. After removing most of the mud and sand, pour them into a large basin and flatten them so that the thickness does not exceed 10 cm. Cover the surface with a piece of gauze and flood it with water for 2 to 3 cm. After about 1 to 2 hours under weak light, the red worms will come out of the gauze holes. Lift the four corners of the gauze to get pure red worms that are completely separated from the mud and sand. Repeat this method 1 to 2 times, take out some more red worms from the residue, and then pour the remaining residue back into the field.

8. Temporary transportation

1. Temporary breeding: The temporary breeding pond is strip-shaped, with a concrete structure, about 1 meter wide, 5 to 10 meters long, and 0.15 meters high. 10 to 20 kilograms of red worms can be temporarily raised per square meter of pond surface. Maintain a certain water flow and turn the pond over twice a day to prevent siltation at the bottom and death of the worms due to lack of oxygen.

2. Transport: For short-distance transport, you can use basins and other containers to pack water earthworms 5 to 10 cm thick, and the transportation time should not exceed 3 hours. For long-distance transport, you can use oxygen-filled bags for packaging. Each bag should not contain more than 10 kg of red worms, add 2 to 3 kg of water, and sufficient oxygen. When the temperature is high, you need to add an appropriate amount of ice in the packaging compartment to ensure safe transportation to the destination. If the transportation volume is large, you can also use large barrels or baskets and mix red worms with water in a ratio of 3:1. Continuously oxygenate during transportation to ensure that they will not die due to lack of oxygen. It should be noted that when packaging red worms, you should try to avoid mixing in residues and dirt to prevent dirt from deteriorating the water quality during transportation and causing water to die due to lack of oxygen.

Through the above introduction, we now know the red worm breeding technology. Red worm breeding has considerable benefits. It is very promising to actively develop red worm breeding. It can be raised in ponds or fields. Pond breeding has the highest yield, with an annual output of 750 to 1,000 kilograms per mu. Based on the current lowest market price of 20 yuan per kilogram, the output value reaches 15,000 to 20,000 yuan, and a net profit of 8,000 to 12,000 yuan can be obtained.

2. How to breed red worms?

Step/Method 1

Pool and density: When breeding red worms artificially, the number is generally large, and it is very common to breed them on a large scale. The first thing to pay attention to is the breeding pool and density. You can use a cement pool to breed red worms. The depth of the water can be controlled at 20-30 cm. It does not need to be too deep. Some silt can be placed at the bottom of the pool. The number of red worms should not be too large, otherwise the dissolved oxygen in the water will be insufficient, and there will be insufficient food.

Step/Method 2

Food: There are many kinds of food that red worms can eat. Some red worms only eat meat, while others are omnivorous and can eat both meat and vegetables. Even some bacteria can become their food. If you are breeding red worms artificially, you can also add some glucose to the water, which will help the red worms grow better.

Step/Method 3

Water temperature: When breeding red worms, you need to pay special attention to the water temperature, because the water temperature has a relatively large impact on the growth and development of red worms. Red worms are more afraid of heat, but not too afraid of cold, so it can be kept at around 10 degrees, or even more than 10 degrees. When the temperature is suitable, the growth and reproduction speed of red worms are relatively fast.

Step/Method 4

Water change: When breeding red worms, you must pay attention to water changes, otherwise the water quality will be poor and the dissolved oxygen content will be insufficient. The specific frequency of water changes can be determined according to the state of the water in the pool, and the water quality in the pool can be monitored in real time.

Step/Method 5

Light: Red worms don't like strong light, so try to keep the pool darker. If there is strong light during the day, it is recommended to cover it in time.

3. What kind of feed is best for red worm breeding base?

Feeding

Most large-scale professional red worm farms use rice bran, sawdust, banana peels, bagasse, sludge, pigeon manure, etc. to ferment and make them into breeding feed. Home-based red worm breeding can use yeast powder soaked in water to feed, but the amount must be controlled.

4. What are the breeding techniques for red worms?

1. Breeding pond: Bloodworm breeding is generally carried out on a large scale, so a breeding pond is needed. The number of bloodworms to be put in can be determined by the size of the breeding pond, and the water depth. When breeding bloodworms, the water should not be too deep. Generally speaking, 20 to 30 centimeters is more appropriate. In addition, some silt needs to be placed at the bottom of the pond, where bloodworms like to move around.

2. Food: The main food of red worms is plankton and organic debris in the water. When the water is rich in nutrients, the growth rate of red worms will be fast. Therefore, it is best to add some fermented fertilizer to the water regularly, so that the nutrients in the water will be richer. 3. Water quality: It is more appropriate to use river water or pond water to breed red worms, because such water is closer to the native environment of red worms, but tap water is more convenient. But don't use tap water directly. It is best to expose them to the sun for two or three days and wait until the chlorine in them is basically removed before using them. Red worms do not have high requirements for water quality, but water quality is closely related to dissolved oxygen, so water changes must also be done well.

5. How to breed red worms?

Step/Method 1

When breeding red worms, prepare a glass container, put the selected red worms into it, and then inject clean and sterile natural water. If you want to use tap water for breeding, it is best to expose the tap water to the sun for 2-3 days to remove the chlorine in it to prevent poor growth of the red worms.

Step/Method 2

Control light source

The growth of red worms cannot be separated from light. Lack of light source will cause the red worms to have difficulty breathing and suffocate to death. When breeding, it is best to hang a 5-watt light bulb above the container to provide the red worms with sufficient light, allowing them to breathe freely and grow healthily.

Step/Method 3

Water quality control

When breeding red worms, the water should be changed once a day to keep the water clean. In the process of changing the water, the red worms and the container should be cleaned to remove the mucus to avoid the breeding of bacteria. The breeding water depth should be controlled at about 3-5 cm, and the water level should be deepened at night to keep warm.

Step/Method 4

Feeding. Red worms mainly feed on organic debris in the soil, and they particularly like sweet and acidic baits. Poultry manure, domestic sewage, etc. are all their baits. In professional farms, rice bran, sawdust, sludge, pigeon manure and other raw materials are generally fermented to make feed. If it is a family farm, yeast powder can be soaked in water and fed. Feeding is also a key point in red worm production. Feeding in small amounts and multiple times can increase production. Generally, feeding is done once every 3-4 days, and 50 to 100 kilograms of manure is fed per mu each time. It is mixed with water and sprinkled throughout the pond. When feeding, pay attention to the amount of residual bait, and do not blindly feed more, so as to avoid excessive organic matter in the water body causing fermentation to produce toxic substances, affecting production.

6. 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.

7. What is the largest red worm breeding base in Guangdong?

Guangdong Province Zhuhai Jinbita Breeding Co., Ltd.

The company has a 300-acre red worm breeding base, which is located on the banks of the Xijiang River. There is no industrial pollution within dozens of kilometers around it. The soil is fertile, the water quality is excellent, the roads are smooth, and the transportation is convenient. "Red worms" are the best natural bait for tropical fish and ornamental fish, and there is a broad market demand at home and abroad. The growth of red worms is limited by natural conditions such as climate, soil, and water sources. At present, only two or three companies in the Pearl River Delta have the production conditions and capabilities.
