CATDOLL : CATDOLL: What is the effect of water earthworms on water quality? (What does the effect of water earthworms on water quality mean?)

1. How to raise earthworms at home?

In autumn every year, when the temperature drops to about 28℃, the water earthworms can be introduced into the pond. The water earthworms are abundant in sewage ditches in the suburbs of towns, livestock and poultry farms and slaughterhouses, sugar factories, and sewage ditches where waste is discharged by food factories. Seeds can be collected nearby. The inoculation work is relatively simple, that is, the collected earthworm seeds are evenly spread on the culture surface of the earthworm pond. It is appropriate to inoculate 500-750 grams per square meter of culture area.

It is more appropriate to control the water depth at around 3 cm. In fine weather in early spring, the water can be shallower during the day to help increase the water temperature, and it can be appropriately deepened at night to help keep warm and prevent freezing.

Too much water flow will not only take away nutrients and eggs on the culture surface, but also increase the energy consumption of the earthworms 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, thus leading to deterioration of water quality and the death of a large number of earthworms.

Practice has shown that a flow rate of 5-10 liters of water per second per acre of breeding field is sufficient. Water maggot ants 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 used to treat fish diseases cannot be used.

2. What’s the matter with the bugs in the turtle’s water?

First of all, I can say for sure that this is a normal phenomenon, and there is no need to panic! The red striped worms that appeared in the turtle pond for no reason are actually the "water earthworms" that we often talk about in our daily lives. They are striped, have red bodies, can twist, and are very active. The appearance of water earthworms indicates a most basic problem: the water quality has been polluted to a certain extent! The possibilities of "water earthworms" pollution are as follows:

It may be that the water in the turtle pond has not been changed for a long time. After static water has been left for a long time, it is easy to attract small creatures such as mosquitoes that like humid environments. These small creatures lay eggs on the green plants, pool walls or water in the turtle pond. Over time, they will slowly hatch water earthworms, mosquito larvae and the like; the best broad-striped flame turtle.

It may be that there are insects laying eggs and ovums at the water inlet of the turtle pond. When we change the water in the turtle pond, the eggs are washed into the turtle pond. Over time, the situation mentioned above will occur.

3. Why not use earthworms to feed ornamental fish?

At the current price of water earthworms, if you feed them to goldfish, it is estimated that the fish food cost is more expensive than feeding them to dragon fish, which is a bit uneconomical, unless you can catch them yourself, but now in the wild, this thing is very rare. The most critical problem, which is also the most worrying for fish lovers, is too many bacteria and parasites.

In addition to the above-mentioned reasons why fish lovers are reluctant to use earthworms to feed fish, more factors are that earthworms contain more bacteria and parasites. Especially at present, water pollution in various places is generally serious, and many fish lovers dare not feed their ornamental fish easily.

4. Is there any difference between water earthworms and earthworms in the ground?

The difference lies in the different living environments. Water earthworms generally live in the mud on the banks of rivers or at the bottom of rivers. They are densely packed on the surface of the mud, with one end fixed in the mud and the other end growing out of the mud and trembling in the water. Once disturbed, they immediately retract into the mud.

The earthworms live in the soil. Their long-term burrowing life has caused their heads to degenerate and they have no eyes. They feed on animal and plant debris in the soil.

The earthworm in the ground is a kind of annelid with a slender and soft body. Its whole body is composed of many similar segments.

It often drills holes underground to loosen the soil, making it easier for water and fertilizer to enter, thereby improving soil fertility and facilitating plant growth.

Water earthworm: also known as red threadworm and red nematode, it is an aquatic oligochaete among annelids, with bright red or bluish-gray body color.

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.

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 quantities and they are edible.

5. Can earthworms be put into fish tanks to purify water?

Putting water earthworms into the fish tank cannot purify the water. Because there are a lot of bacteria and pathogens in the living environment of water earthworms, if they are not handled properly, they will cause various diseases in fish, especially when the seasons change. The water earthworms on the market are only cleaned of the mud and impurities of the red nematode group with tap water before being sold. However, there is still some mud in the living water earthworms. You can feed them in a basin of clean water for a period of time, and they will spit out the mud (the red nematodes that have spit out the mud can be used to feed fish, even if there are some surviving live bodies, there is no need to worry about water pollution).

Of course, old goldfish keepers all liked this thing. There is a saying that "fish and worms retain water". Although water earthworms are dirty, they can strengthen the physique of goldfish to a certain extent, and they are rich in nutrition.

6. Where do the little earthworm-like worms come from?

Water earthworms are found in the mud. 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 of the Huangpu River in Shanghai recedes, a large number of water earthworms grow in the mud on the shore. Every spring and autumn, people will catch them in large numbers. When they encounter strong light and high temperature, they will die in large numbers and emit a fishy smell.

The appearance of water earthworms often reflects the presence of organic pollution in some aspects of the water quality. In addition, since they carry a large number of bacteria, they can also cause symptoms such as diarrhea.

7. Will earthworms pollute the water if they eat fish feces?

Water earthworms eat fish feces and will not pollute the water.

It can purify water quality and basically can play the role of purifying water quality, except for some pathogens and protozoa.

The equipment for artificial earthworm breeding is simple and easy to manage. Generally, you can use the open space in front of and behind the house, the courtyard, old wooden boxes, waste barrels, pots, bamboo baskets, brick pools, seedling hotbeds, etc. to cultivate medicinal earthworms. You can also use vegetable fields, orchards, nurseries, etc. to combine earthworm breeding, which can benefit from dual utilization.

8. I found a red thread-like worm in the toilet. What is it?

Red thread-like worms were found in the toilet. These nematodes are also called water earthworms or red silk worms.

Red nematodes, also known as water earthworms and silk earthworms, are red and slender. They live their entire lives in the mud at the bottom of the water with micro-flowing water and lots of decaying organic matter. They have a strong reproductive capacity. Red nematodes are not parasites and are not toxic. The main reasons for the presence of this type of red nematode in tap water are as follows: the secondary water supply tank is poorly managed and not cleaned in time, and the earthworm eggs deposited in the water tank are hatched and developed.

9. Where do the nematodes in the toilet come from?

It may flow in through the water pipes. It may be that the water tank is not cleaned in time, causing the earthworm eggs deposited in the water tank to hatch and develop into red nematodes. Or it may be that the water pipes in the community are corroded, causing microorganisms to grow in the tap water and flow into the home.

Red nematodes are also known as water earthworms and red silkworms. Their appearance often reflects the presence of organic pollution in some aspects of water quality.

Red nematodes have high nutritional value and are often used as fish bait. Water earthworms are bright red or dark red, live in freshwater areas, and like to gather in clumps.
