CATDOLL : CATDOLL: What is a big red worm?

1. What is a big red worm?

The big red worm is bright red and very beautiful. It is the best bait for winter fishing. The worm is red and shiny, with a black head and claws all over its body. It is a plump pest.

2. Artificial breeding of red worms: 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 water in the pond 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.

Additional information:

Nutritional value:

The bloodworm contains a lot of protein, up to 40%-60% of the dry weight of the body. Protein contains all the amino acids needed for fish growth. It is reported that protein bait can only increase the metabolic intensity of goldfish by 20%-30%, but if goldfish are fed with water fleas, the metabolic intensity can be increased by 100%. The fat content in water fleas is also very high, and goldfish will become fatter after swallowing them.

The carbohydrates, calcium and vitamins in Daphnia are also very rich. The nutritional value of Daphnia as bait for goldfish is unmatched by other granular baits.

It not only has high protein content, but also contains essential amino acids, vitamins and calcium for fish. Daphnia is a high-quality bait for freshwater fish such as eels. It is relatively easy to cultivate. For small-scale breeding, bottles, cans, tanks, etc. can be used; for large-scale breeding, earthen ponds and cement ponds can be used.

Red worm (water flea) breeding technology:

light source:

First, prepare a container. It can be a small tank, a pet box, a PET bottle, etc. The best suggestion is to use a container with a larger area of ​​contact with air. Because Daphnia will float to the surface of the water and have a breathing action, so if there are a lot of them, some of them may not be able to compete for a position and die. Light source: Generally, breeders are told that as long as there is light, it will be fine. Then...what about at night? Won't they all sink to the bottom? That's right, they sink to the bottom, and as a result, most of them die the next day. Why? Because they are too lazy to breathe. Therefore, it is recommended that the light source should not be turned off at night. You can use a small light source (such as a 5w night light, etc.) to illuminate it, so that this trouble can be avoided. Of course, some people will say, do you have to raise it like this? The answer is not necessarily, but there is a need to have a large number of them. We raise it not just for fun, but the key is the number of pots. Only when there are enough can we feed the fish, right?

Feeding:

Generally, people tell breeders to feed Daphnia with yeast powder soaked in water, but if the amount is not well controlled, the water quality will deteriorate quickly, causing Daphnia to die quickly, and then they will have to buy Daphnia again or ask for more from others. So, my method can be considered to prevent this. At the same time, you don’t have to worry too much about buying yeast powder, because sometimes yeast powder is hard to find, or it comes in a big bag and you can’t use it up. Because later I thought, if I soak yeast powder in water and feed them, then can I feed them with anything that is soluble in water? The answer is yes, because Daphnia are filter-feeding creatures, so they generally survive by filtering nutrients in the water, because if the things we throw down are soluble in water, they can eat them. Because, Daphnia tried "sheep blood" to feed and found that the effect was good, and later I heard that the reason for using yeast powder is that there are some amino acids in it, and Daphnia can eat this. As for amino acids, I can't get them, so I have to use fresh milk, I believe it will also have a good effect.

Daily care:

In fact, you don't need to pay much attention to them. Just give them light and some feeding. As for changing the water, after sucking out the water fleas each time, add the amount of water that was sucked out. If there are too many algae, it's also good to put some apple snails. As for the effect, it depends on you to try it yourself. As for the amount of feeding, don't feed too much at a time. 2~3cc at a time is enough. Don't think it's too little. This is enough and it won't cause the water quality to deteriorate at once. As for filtering water fleas, this is much easier than filtering brine shrimp. If you don't want to filter, you can use its phototropism to do it. Use light to attract them and then suck them out with a dropper, then wash them with plenty of clean water, and then you can feed them. If you want them to be more nutritious, feed them some nutrient solution before feeding, and feed them to the fish after one to two hours. Huhulu Gunbi is more nutritious this way.

3. Is the red nematode a sandworm?

No.

Water earthworm: also known as red silkworm, red nematode, red nematode, belongs to the aquatic oligochaete among the annelids, with bright red or blue-gray body color. They mostly live in the mud on the banks of rivers or in the bottom of rivers, densely packed on the surface of the mud, with one end fixed in the mud and the other end sticking out of the mud and trembling in the water. Once startled, they will immediately retract into the mud. Water earthworms have extremely high nutritional value and must be repeatedly rinsed in clean water before feeding. They are a favorite bait for goldfish and koi, and are also the main bait for eel fry and young turtles.

Sipunculus nudus, also known as naked starworm, commonly known as "sandworm", is not a sea intestine. It is shaped like an intestine, long and cylindrical, about two centimeters long, and naked and hairless. The longitudinal muscles of the body wall are bundled, and each circular muscle is staggered to form a square grid pattern. Although the Sipunculus nudus is not as precious as sea cucumbers, shark fins, and abalone, it tastes delicious and tender, which is better than sea cucumbers and shark fins. It grows on coastal mudflats. Because it is very sensitive to the quality of the growing environment, it cannot survive once it is polluted, so it is called an "environmental marker organism."

Water earthworm: also known as red silkworm, red nematode, belongs to the aquatic oligochaete among the annelids, with bright red or blue-gray body color. They mostly live in the mud on the banks or riverbeds of rivers, densely packed on the surface of the mud, one end fixed in the mud, and the other end trembling in the water with mud. Once disturbed, they immediately retract into the mud. Water earthworms have extremely high nutritional value and must be repeatedly rinsed in clean water before feeding. They are a favorite bait for goldfish and koi, and are also the main bait for eel fry. After the Huangpu River in Shanghai recedes, a large number of water earthworms grow in the mud on the banks, and people catch them in large quantities every spring and autumn.

Sandworms Sandworms

Sandworms are also called sand intestine worms. They are shaped like an intestine and are long and cylindrical. Although sandworms are not as precious as sea cucumbers, shark fins, and abalones, they are delicious, crispy, and tender, which is better than sea cucumbers and shark fins. Sandworms are most famous for those produced in Longtan Village, Beihai City, Guangxi. Visitors to Beihai should not forget to eat and buy sandworms. When processing sandworms, the sand intestines in the abdomen should be cut off, otherwise it will be difficult to eat. If it is dry sandworms, you must first cut the sandworms into small strips and fry them in a pot. When frying, you must keep turning them over. If you find that the heat is enough, take out the strips and soak them in clean water for a while. This can not only remove the sand, but also fry the fragrance of the sandworms themselves. Remember, only fried sandworms will taste like sandworms.

Of course! Sandworms are a kind of mollusk on the beach, and they are quite big! They move very fast in the sand! Red nematodes... The empty bend is the fish and the food!

no

Red nematodes generally refer to water earthworms, and they are still water earthworms when they grow up. The red worms that turn into mosquitoes are mosquito larvae, which are shorter and thinner than red nematodes. Both are used for fish farming. Many more people use red worms than red nematodes because red worms have high nutritional value and are suitable for a wider range of fish species. The most important thing is that the growth environment of red nematodes is silt, and the possibility of carrying harmful bacteria is much higher than that of red worms.

The whole body of the "red nematode" is red and slender, generally about 4 cm long, and can be up to 10 cm long. Red nematodes generally live in river water and sewage, and their reproductive capacity increases as the temperature rises. Experts believe that red nematodes are not parasites. Although eating them will not cause direct harm to the human body, the bacteria they carry and their excrement can cause gastrointestinal discomfort in people, leading to symptoms such as diarrhea, nausea, and vomiting. At the same time, as an "indicator organism" of unclean water, its existence indicates that tap water has been organically contaminated at some point in the transportation process.

Bloodworms are the larvae of chironomids. In the north, they are sold in flower and bird markets. There are about 5,000 known species of chironomids in the world. They are similar to common mosquitoes, but the main difference is that they have dense fine hairs on their antennae, just like feathers. Another difference is that their mouths (stylets) have degenerated and do not have the function of sucking. Therefore, we can say that they will not bite people. Bloodworms also have a skill, which is that they can live in a relatively oxygen-deficient environment. Because they have hemoglobin in their bodies, this is why they are blood red.

Chironomid larvae have become an important biological resource. They are widely distributed in various water bodies and are found in large numbers. Their biomass often accounts for 50% to 90% of the total benthic animals in the water. Bloodworms are an important part of the food chain in water bodies and are excellent natural bait for a variety of economic aquatic animals such as fish, shrimp, crabs, turtles, and tortoises. Chironomid larvae are rich in nutrients, with protein content accounting for 41% to 62% of dry matter and fat accounting for 2% to 8%. In aquaculture, chironomid larvae have many advantages: suitable size, good palatability, and comprehensive nutrition.

A large number of larvae can breed in sewage and stagnant water. Most chironomid larvae feed on organic matter in water. In silt or water bodies rich in organic matter, they can reproduce in large numbers due to the lack of natural enemies such as fish and shrimp. In the north, there are usually two generations a year, and April-May and September-October are the breeding seasons of chironomids (varies in different regions).

At present, bloodworms are artificially bred as feed.

Artificially raised bloodworms are mostly used as food for fishing and home-reared tropical fish.

Sandworms are also called sand intestine worms. They are shaped like an intestine and are long and cylindrical. Although sandworms are not as precious as sea cucumbers, shark fins, and abalones, they are delicious, crisp, and tender, which is better than sea cucumbers and shark fins. Sandworms are most famous for those produced in Longtan Village, Beihai City, Guangxi. Visitors to Beihai should not forget to eat and buy sandworms. When processing sandworms, the sand intestines in the abdomen must be cut off, otherwise it will be difficult to eat. If it is dried sandworms, you must first cut the sandworms into small strips and fry them in a pan. When frying, you must keep turning them over. If you find that the heat is enough, take them out and soak them in clean water for a while. This can not only remove the sand, but also fry the fragrance of the sandworms themselves. Remember, only fried sandworms will taste like sandworms.

Sandworm and lean meat soup

Material

150 grams of dried sandworms, 250 grams of lean meat, 25 grams each of yam, wolfberry and longan.

seasoning

Two slices of ginger and a little salt.

practice

① Soak the dried sandworms in warm water. When they become soft, cut them open with scissors and clean the sand inside.

②Put the lean meat into boiling water and cook on high heat for 3 minutes, then take it out and wash it.

③Wash yam, wolfberry and longan meat.

④ Bring appropriate amount of water to a boil over high heat for 6 minutes, add all ingredients and ginger slices, simmer over medium heat for 40 minutes, and season with salt.

Sandworms belong to the coelenterate class and are also known as naked starworms, sand intestines, checkered starworms, etc. Their bodies are long and cylindrical, very much like an intestine, about 10 to 20 cm long, and they are naked and hairless. The longitudinal muscles of the body wall are bundled, and each ring muscle is staggered to form a square grid pattern, so they are also called naked checkered starworms. They live in the sea area with sandy and muddy bottoms along the coastal mudflats. They drill out at high tide and lurk in sandy and muddy holes at low tide, so they are called Hongyin sandworms. The larvae or adults of sandworms have no segmentation phenomenon, and their muscles are relatively developed. They usually feed on silkworms, but their body structure is simple, so the sand in the intestines can be washed away and the whole worm can be eaten. In particular, the sandworms produced along the coast of Xialiu, Zhanjiang are famous for their large size, thick meat and high quality.

Sandworms, although not beautiful or elegant in name, are no less nutritious in nutrition, taste, medicine and therapeutic value than other precious marine products, so they are known as "beach sausages". Sandworms are tender and crispy, delicious, nutritious, rich in protein, fat, calcium, phosphorus, iron and other nutrients, especially in taste, better than sea cucumbers and shark fins. Because sea cucumbers and shark fins themselves have no taste, chicken or lean meat must be added when cooking, otherwise they will be tasteless. Sandworms have a delicious taste, no other ingredients are needed, and they are very distinctive when eaten dry or fresh. In addition to urban and rural residents, they are also precious delicacies in hotels and restaurants. Sandworms also have high medicinal effects and therapeutic value. They are cold in nature, sweet and salty in taste, and have the effects of nourishing yin and reducing fire, clearing the lungs and replenishing deficiency. According to medical records, sandworms are the most suitable for people with symptoms such as bone steaming and hot flashes, night sweats due to yin deficiency, cough and asthma due to lung deficiency, chest tightness and excessive sputum, and low milk supply in women after childbirth. For symptoms such as tuberculosis cough, neurasthenia, spleen deficiency or dryness in children, sandworms and ginger slices boiled lean meat soup are effective. Because sandworms nourish yin and tonify the kidney, children with frequent nocturia due to kidney deficiency can get good results by eating sandworm porridge. Therefore, sandworms are a good nutritional tonic and food therapy product suitable for all ages.

Sandworms, also known as earthworms, are the main ingredient of the Fujian snack "earthworm jelly".

The current market price of Longtan sandworm is about 1,600 yuan per kilogram.
