CATDOLL : CATDOLL: Does breeding red worms cause serious environmental pollution? (Does breeding red worms cause serious environmental pollution?)

1. Why are red worms prohibited in black ponds?

First, the main reason is that fish like red worms too much. No matter how the black pit boss adjusts the bait eating habits in the breeding, it will be useless when it comes to red worms. If you can catch 10 catties of fish with other baits, you may be able to catch 20 catties with red worms. The effect is so obvious that the boss can't afford to lose money and will definitely not do it.

Secondly, in addition to this, red worms may also cause fish to have a biased taste in the mouth, which is not conducive to black pit breeding in the short term.

Third, using a large number of bloodworms will also cause water pollution and make fish sick. Therefore, almost all black pits explicitly prohibit the use of bloodworms as bait.

2. Will fish and insects pollute the water quality?

The uneaten red nematodes die and decay. Red nematodes are muddy water organisms that will die after a few days in fresh water, damaging the water quality. Moreover, fish will not eat the dead red worms, and parasites will be produced in their bodies, such as small claw worms, which will cause harm to fish.

It is recommended to feed 1-2 red worms to each fish, and the rest should be removed in time. If dead red worms are found, they should be removed in time and the water should be changed and the fish tank should be cleaned. Red worms are not nutritious, so it is recommended to use mealworms.

3. Analysis of the benefits of red worm farming?

Bloodworms are currently the most commonly used natural bait in aquarium farming. They are also the best tropical fish live feed for workers and are widely farmed. So what are its profits and prospects? How should they be farmed?

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.

The lifespan of red worms generally ranges from 80 to 120 days, so farmers must harvest them in a timely manner and drain and dry the fields after harvesting.

4. What impact does red nematode have on sea cucumber farming?

Will affect sea cucumbers.

Water earthworms, also known as red silkworms and red nematodes, belong to the aquatic oligochaetes among the annelids, with bright red or flesh-red or orange-yellow body color. They mostly live in the sewer sludge (usually slow-flowing black sludge) of sewage or wastewater, densely packed on the surface of the sludge, with one end fixed in the sludge and the other end sticking out of the sludge and trembling in the water. Once disturbed, they immediately retract into the sludge.

The nutritional value of water earthworms is extremely high. They must be rinsed repeatedly 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. They are often used for fishing in Sichuan and are the best bait.

When the tide recedes in Shanghai's Huangpu River, a large number of water earthworms grow in the mud on the shore. Every spring and autumn, people catch them in large numbers. When exposed to strong light and high temperature, they die in large numbers and emit a foul odor. The appearance of water earthworms often reflects organic pollution in some aspects of the water quality. In addition, because they carry a large number of bacteria, they can also cause symptoms such as diarrhea.

Fishing method

Water earthworms are mostly caught in shallow waters of river branches and silt ponds. Use a fine-mesh scoop net to scoop from the surface of the riverbed silt and two centimeters below the mud. There are a lot of water earthworms in the residue obtained after rinsing in water.

Collect enough mud and earthworm mixture and place it in a large basin, fill it with water and cover it with a lid to shade it. When the earthworms are concentrated on the water surface, scoop them out by hand. When all the earthworms are gone, only water and mud will remain.

5. Are red nematodes harmful to planted tanks?

These things cannot activate the bottom sand. They only have a lifespan of 2-3 months and will pollute the water quality after they die under the bottom sand.

6. What is the growth and reproduction environment of red worms?

Red worms like to stay in some fertile water with stable water flow, so they start to reproduce in large numbers during the Spring Festival every year. They will swim on the water surface, sometimes making the water surface appear red. They can be caught well in containers. At this time, the silt and red worms can be salvaged together and placed in a clean glass container. Use some natural pure water for breeding. If you want to use tap water for breeding, you must put them under the sun for two or three days before using them as reasonable breeding water. Change the water in time every day and take some very good warming measures.

Breeding requirements: During artificial breeding, the water depth is generally maintained at about three to five centimeters. Especially in spring, when artificial breeding is carried out, the water level can be slightly lowered. This method can effectively increase the water temperature. Deepening the water level at night can effectively keep warm. They don't like the water to flow too fast, otherwise it is easy to wash away some nutrients in the soil and their eggs. But you should also pay attention to the speed of the water flow. It can't be too small, otherwise it will be detrimental to their excrement discharge, causing serious pollution to the water quality. There should not be any chemical plants near the farm, because they are very sensitive to harmful substances.

Reasonable food: It mainly takes some organic fertilizers in the soil as its main food, and it likes some sour and sweet feeds very much. For some animal and poultry feces, and some sewage in daily life, they can be used as their food. You can use silt pigeon feces and rice bran, after sufficient mixing and fermentation, it will become their unique food. For some smaller farms, you can also soak them with yeast powder in warm water and feed them. Under normal circumstances, they need to be fed once every three days. One mu of land should be fertilized more than 50 kilograms each time, and a certain amount of water should be added, and then sprinkled after sufficient mixing.

How to breathe correctly: In order to allow the red worms to breathe freely during their growth, the quality of the air must be guaranteed. Natural air flow should be allowed in the breeding area. More contact with the air can effectively increase the oxygen content. When the temperature is too high, some artificial methods can be used to increase the oxygen content in the breeding area. When the temperature is below zero, freezing will occur. At this time, they will easily freeze to death. Other warming measures can be used to reduce the ice on the water surface, which can effectively allow them to grow.

Diversified food: For artificially cultivated red worms, you must add food to them in time to prevent them from starving to death or other physical diseases during the growth process. Since they like to eat sweet or acidic foods, you can add some fresh animal blood to some rice powder, stir it thoroughly, and feed them after fermentation. Sometimes when the weather becomes hot, the amount of food they eat will decrease. Choose to feed them in the morning every day and change the water according to the daily temperature.

Sufficient light: They like some sunlight, especially in the breeding site, you can place some other algae plants, in order to avoid water pollution, you must strictly control the amount of feeding. It is not very strict about the light requirements, only weak light is needed to survive well, every time you feed, you can put the food in a lighted place, so that you can lure them.

In the process of feeding them, we must adhere to the principle of feeding less, and the water quality in the breeding site must be kept fertile, so that some algae inside can reproduce. Fertilize them regularly, and you can catch them once a year in spring and autumn.

7. What are those little red worms that look like earthworms in well water? Are they harmful to the human body?

Red nematodes pollute water and can easily cause diseases.
