Probably, any experienced aquarist will agree with the opinion that it is best to feed the fish with bloodworms or other live food. This ensures excellent health and well-being of the aquarium inhabitants. But here a problem arises. In the warm season, bloodworms can be washed in many reservoirs with standing water. But what about in winter? Fortunately, knowing how to breed bloodworms at home, you can provide the inhabitants of the aquarium with almost any amount of food, and also sell the excess, making a significant profit.
Why do you need bloodworms?
Of course, the most obvious use of mosquito larvae is feeding aquarium fish. Bloodworms contain all the substances necessary for successful and rapid development. Depending on the size, you can feed it to both juvenile and adult fish. With the constant presence of live food in the diet, the fish become larger and the color becomes more saturated. Various diseases, including curvature of the spine in females of viviparous breeds after childbirth, if not completely excluded, are at least reduced in number.
However, breeding worms and bloodworms at home can also be useful for fishing. Mosquito larvae are an excellent bait for many types of fish: roach, bream, perch, bleak and a number of others. However, only large bloodworms are suitable for this. Small ones can be used for feeding - just throw a pinch of larvae into the hole when ice fishing to ensure maximum attention from the fish.
Bloodworm species
Before figuring out how to breed bloodworms at home, it will be useful to know what they can be like. Usually the species is determined by the size of the larvae - otherwise you need to study them for a long time and painstakingly under a microscope, looking for differences known only to highly specialized experts.
Let's start small - the larvae grow no more than 10 millimeters. They usually live at the bottom of rivers with weak currents, in backwaters.
Estuary – larger. It is found in shallow bays, mainly in the southern regions of our country. The sludge here contains a large amount of organic substances necessary for the nutrition of large larvae.
Large (also known as attachment) – larvae of the mosquito-jerk. It is almost never found in rivers and other bodies of water with flowing currents. It usually lives in the mud of ponds, lakes and long-standing puddles. An excellent choice not only for large and aggressive aquarium fish, but also for fishing.
Creating optimal conditions
Before you start breeding bloodworms at home, you need to make sure that the living conditions are normal. Otherwise, all your efforts may be wasted.
You should start with temperature. The optimal range is considered to be from 13 to 20 degrees Celsius. In such conditions, the larvae develop most intensively and retain their beautiful appearance, which is especially important in cases where bloodworms are raised for sale.
It can be grown at other temperatures, but this will have negative consequences. For example, if the room is colder, the development of the larvae is much slower (in general, bloodworms can withstand even short-term freezing without harm to themselves). And if the room is too warm, the bloodworm gets a thin, delicate shell. This not only makes the hooking process more difficult, but also reduces shelf life.
The next important factor is humidity. Some experts believe that this is not an important circumstance and can be ignored. But others claim that bloodworms develop better if the air humidity in the room is about 70%.
How to breed bloodworms at home
The summer fishing season has crept up unnoticed, and soon everyone will be able to fill the river banks and fill their buckets with fresh catch. While there is little time left, it is worth preparing and thinking about the bait that will be used to catch our future prey. Therefore, allow me to share with you a few secrets and rules on how to properly breed bloodworms at home .
Instructions
1. Prepare a container. Make sure that the capacity of the canister or can is at least 70 liters, otherwise the procedure will be slightly effective. Choose a place where the container is well lit. It should not be closed, rather than everyone, so that it is transparent and easily lets in clear light. If it is not possible to make similar data, do everything possible so that as much light as possible falls on the tank. 2. Fill the canister with water and expose it to light. At this stage, you can not worry about it and make preparations for collection. Go to any pet store and buy a net for catching fish. You will also purchase several bags for storing the collected bloodworms or a food container, one that can be put in the refrigerator. 3. Check your crop about a week after you added water. If necessary, add water and remove accumulated dirt and debris from the surface. By the way, keep in mind that it is best to tightly fence off your container from your living space. Mosquitoes will begin to attack your apartment in five to ten days. 4. Cover your aquarium with something, on the contrary, uninvited guests will peck at your crop, check from time to time so that no one encroaches on it. With proper freezing, the bloodworm will retain its attractiveness for another five to six weeks after collection, which allows you to make a large harvest and go “in the lead” with half a kilo of bloodworm . Don’t forget to add water and keep it clean, and you are guaranteed a harvest!
As usual, huge fish farms are engaged in fish farming. But few people know that fish can be raised even in a small pond built in an ordinary courtyard of a country house or in a country house. And it turns out that there is nothing difficult or strange in setting up such a mini-fish farm.
Instructions
1. Finally, it is unlikely that you will be able to breed decent fish in a country pond, but carp and crucian carp are quite unpretentious and survive beautifully in the most modest conditions. They do very well in shallow, well-heated reservoirs that are not flowing or have very weak flow. For their breeding, a pond with a depth of one to one and a half meters and dimensions of 4 by 6 meters will be absolutely sufficient. In such a pond there will be enough space for several carp, or even for a couple of dozen crucian carp weighing up to 300 grams. Having purchased fish, you should not rush to release it into the pond; make sure that the temperature of the water in which the fish is located and the temperature in the pond are the same; a temperature difference of even a couple of degrees will cause temperature shock in the fish, which can lead to the death of the fish literally within the first 24 hours. 2. Crucian carp and carp are water piglets, so to speak, in the sense that they are unpretentious in food, and you can feed them whatever is desirable. Along with protein food (worms and larvae), they can also be given cereal food, based on the calculation of 5% of the total mass of fish in the pond. That is, if you have 3 kg of crucian carp swimming in your pond, then they will need 150 grams of steamed grain or feed per day. It is better to feed 1-2 times a day at the same specific time. You can even hang a small bell near the pond; fish will swim out to its sound and immediately eat the share given to them. They will get used to the routine, the food will be better digestible, and its remains will not rot, clogging the water. Ideally, you can make a special galvanized tray for feeding, and place the food in the water in it only for the feeding period. This technique will allow you to better control the amount of food eaten and protect the pond from clogging. 3. Make sure that the fish do not become narrow in the pond; if your crucian carp stay at the surface of the water, gasping for air, then they obviously do not have enough oxygen dissolved in the water. It is necessary to either add water to the pond or reduce the number of your fish farm. This kind of dacha fish farming involves catching every fish from the pond in the fall. Your pond is very small, in winter it is most likely to freeze, and the fish will die due to lack of oxygen. It may happen that you are not an exceptional fisherman who has his eye on your crucian carp. If you notice that a heron or some other lover of fresh fish has begun to fly to the pond, then you will have to stretch a thin mesh over the surface of the pond. Breeding fish in a summer cottage is an interesting business, and having released the first fish into the pond in April, in August you will be able to start catching them for a light dinner at sunset.
Bloodworm is one of the most famous baits among anglers. You can fish with this bait all year round, exclusively in spring, winter and late autumn, when rivers enter their banks, the water brightens, and fish awaken non-vegetarian tastes. There is no need to spend money on buying bloodworms; you can get them independently.
You will need
- – long stick;
- – sieve;
- – scoop;
- – gauze;
- - bucket;
- - newspaper;
- – foam plastic or wooden box;
- - textile.
Instructions
1. There are several effective methods for catching bloodworms that will not pose any special difficulties for fishermen. Mosquito larvae can be found in muddy places or in shallow water. In order to get bloodworms in winter, you need to make a hole in the ice, measuring one meter by one meter. Take a long and strong stick and attach a scoop to its end. Lower it into the hole and scoop up the sludge in which the bloodworms live. After this, transfer the sludge into a sieve and rinse in water until the mosquito larvae without the sludge remain in the mesh. If you want to get only huge bloodworms, then you should choose a mesh of the appropriate size; small larvae will be washed out. 2. In the summer it will be a little more difficult to get bloodworms, there are only a few of them, and it’s difficult to detect. You need to look for mosquito larvae in the same places as in winter, just choose more shaded areas with cool water. Make a huge bag from several layers of gauze, put a stone and fish waste in it, and lower it to the bottom. The gauze bag should lie in the water for at least a day. After time, pull out the bag, in it you will find the bloodworm you need. In order to sort the large ones from the small ones, you can wash them through a sieve. 3. There are places where bloodworms are found in abundance; it’s easy to get them while fishing. Simply scoop up a bucket of mud and place it near the fire. The bloodworm, feeling the warmth, will rush to the surface. All that remains is to collect the mosquito larvae. Scatter the collected bloodworms on the newspaper; after twenty minutes of drying, the larvae will become bright and mobile. Place them in a foam or wooden box with small holes, and line the bottom with a damp cloth in advance. 4. In order to keep the bloodworm alive for a long time, wrap it in a damp piece of canvas or burlap. Moisten the flap and squeeze it out lightly, scatter the larvae in a thin layer on one half of it along with scraps of damp paper and some drunken tea, lay two more such layers, separating them with a damp sheet of paper, cover with the second half of the canvas on top. Keep the bloodworms in this form in the cold (in winter - on the windowsill or by the balcony door, in summer - on the bottom shelf of the refrigerator). Video on the topic
It is not in vain that they say that dear ones scold - they only amuse themselves. Relationships between lovers, which from the outside seem unfavorable, can be absolutely satisfactory for all of them. Some people like to heat up the intensity of feelings with crazy quarrels and passionate reconciliations. However, there are situations in which friends and relatives are simply obliged to insert themselves into the life of a couple. These are situations of any assault and other types of domestic violence by a man.
Instructions
1. Determine the degree of threat to the life and health of your friend. If you find out that her husband is beating her, you absolutely need to help her. Moreover, in some situations, psychologists recommend acting assertively, not heeding the victim’s attempts to justify the scoundrel. Situations of domestic violence are very rarely isolated. If a man is generally good at hitting a woman, as usual, he will not limit himself to one episode. And the longer a woman stays with such a man, the more difficult it is for her to leave him. The more serious may be the physical injuries and psychological trauma that her husband will inflict on her. 2. Look for experts who will tell you how to competently deceive your girlfriend in this situation. These could be doctors, psychologists, lawyers. The fact is that in many cases of domestic violence, the “executioner” spouse does not want to let go of the “victim” wife. He understands how difficult it is to find a woman who is able to forgive beatings, and therefore will hold on to her to the last. He can intimidate her, persuade her, shower her with gifts, blackmail her. Changing rage for mercy and back, he completely disorients a woman in life, and sometimes only experts can help her in this situation. 3. Look together for options to arrange your friend’s life after the divorce. In most cases, tyrant men leave their wives without a livelihood. Moreover, they even tend to take away her own savings and the money she earns independently. This is also a method to keep the victim close: she often has nowhere to go. Recently, philanthropic organizations have begun to emerge in Russia that allow a woman with children to wait out the moment of divorce from her rapist husband in a shelter. If relatives and friends are unable to help a woman financially, such help centers can become a temporary shelter for her. Note! Keep in mind that by getting involved in this situation, you risk incurring the rage of the victim’s husband and yourself. Prepare your rear and support in the form of strong men who will be able to protect you from the tyranny of a psychopath. Helpful advice Remember that nothing can justify assault on the part of a man. And if your friend tries to make excuses for him, blaming herself for everything, don’t fall for it. This snag requires a quick and tough decision: you need to leave the tyrant. The sooner, the better!
We receive the first batch of bloodworms
First you need to take a sufficient amount of sludge. This is done simply - dirt from the bottom is collected from the nearest body of water (lake or river), which is washed through a fine sieve. As a result, the smallest particles of sludge pass through, while large debris remains in the sieve. The sludge is drained into suitable containers and the garbage is thrown away. The more sludge there is, the better.
The best containers for growing are baking trays about 5-7 centimeters high. Moreover, experts recommend painting them yellow - for some reason it attracts mosquitoes. The sludge is placed in baking trays in a layer of about 2 centimeters. Water is also poured here - no more than 3 centimeters. These baking sheets are left outside (in the warm season, of course) in a place where mosquitoes live. Ideally, the cottage is located near slow-flowing rivers, ponds or even swamps. In a word, the place should be mosquito-proof. The main thing is to place the baking sheets in such a way that they are in the shade at all times. In the sun they will overheat, which will lead to the death of the larvae.
After 3-4 days, there will be a sufficient number of clutches of mosquito eggs in the water. You can continue working.
How to get bloodworms
The largest number of mosquito larvae in the natural environment can be found in the silt of lakes and ponds, abundantly overgrown with bottom vegetation. They are also found in flowing bodies of water. Having determined the habitat, it is easy to wash bait for fish yourself.
The easiest way to do this is to use a fine sieve in which the bottom silt is rinsed. The soil is carried away with the water, and the larvae remain on the sieve. They are easy to collect with a fine-mesh net. Getting bloodworms will not be an insurmountable problem if you use a fork with a long handle and a thin metal wire wound around the teeth. It is tied with horizontal lines at intervals of 6-7 centimeters. By raking the constructed device along the bottom of the reservoir, you can easily catch mosquito larvae.

The third method of extraction is even simpler - the silt is scooped up with a bucket and placed near a hot fire. Feeling the warmth, the bloodworm will float to the surface from which it is collected with a net.
The slowest, but quite effective method of obtaining larvae is to lower pieces of meat or fish wrapped in a gauze bag and loaded with heavy cobblestones to the bottom of the reservoir. In about a day, the trap will have a lot of bait.
How to wash bloodworms is up to each hunter to decide for himself. And to separate small specimens from large ones, just put them in a fine sieve and lower them into a container of water. Large prey will remain on the mesh, and small fry will leak out along with the liquid.
Growing bloodworms from eggs
In general, the technology for breeding bloodworms is very simple. The baking sheets are carefully transferred indoors so as not to spill. Now you need to wait about 2 days and you can carefully examine the silt. Most likely, you will notice tiny worms moving in the mud. This is the bloodworm. True, it is very small, this is suitable only for the smallest aquarium fish or juveniles. But it's better to wait.
In total, the bloodworm grows for about 3 weeks. At any stage, you may decide that he has already grown up enough. There is no point in delaying it any longer - the larvae will hatch into adults. However, this option is also acceptable - we’ll talk about it a little later.
What should I feed him?
In the first stages, the bloodworm will have enough nutrients contained in the sludge. However, not for long. Therefore, over time you will have to feed it. Yeast is best suited for this. They need to be diluted with water, then mixed with sludge and added to the trays at the rate of about 100 grams of yeast per square meter of area. This feeding is enough for 2 weeks. Then you can fertilize again - now dry yeast is used. It is enough to simply pour them out in an even layer over the entire area of the pallet.
Here it is very important not to overdo it - it is better to underfeed the bloodworms, even if this leads to the death of some of the larvae. After all, if you give too much yeast, the water will begin to rot, which will cause the death of all the bloodworms.
Industrial breeding of bloodworms. How to breed bloodworms?
Breeding bloodworms to feed fish
Chironomid larvae are a tasty dish for many fish. To increase the fish productivity of artificial reservoirs by increasing the biomass of such larvae, it will be necessary to breed bloodworms and attract adult mosquitoes belonging to the chironomidae family to the ponds. This can be achieved using different methods. As a result, when comfortable conditions are created, larvae will hatch from mosquito eggs in 2-3 days.
To improve the conditions for female mosquitoes to lay eggs, small areas with aquatic plants (reeds, cattails, reeds, etc.) are preserved in reservoirs.
These areas become the territory over which mosquitoes swarm.
If there are not enough aquatic plants in the reservoirs, then you can use tufts of straw or make small frames from wood in a mesh shape to place mown grass on them in a thin layer.
Such frames are placed in different areas on each pond. Mature mosquitoes burrow and breed at dawn or, more often, at dusk.
Industrial breeding of bloodworms
To attract many mosquitoes, at night the reservoirs are illuminated with electric lights. When raising fry in specialized pools, trays and other structures, bloodworms are reared using the industrial method.
For industrial breeding of chironomid larvae, 2 workshops should be opened at the fish hatchery: a workshop for the formation and preservation of a mosquito population and a workshop for growing larvae.
In both workshops, the air temperature is maintained at 18-20° C and good lighting is provided.
Initially, a mother mosquito culture is formed from a small number of eggs or mosquito larvae, which are taken from the closest pond. After this, their numbers are maintained by artificial breeding.
Ditches for egg laying
Mosquitoes lay eggs in enamel cuvettes filled with clean water located on the floor surface.
The cuvette is selected with a height of 40-50 mm, an area of 0.1 m2 and filled with water to 20-30 mm.
Each clutch of mosquito eggs should be selected from a cuvette and transferred for incubation to earthenware cups filled with 50-100 mm of water.
According to the standard load of eggs transferred for incubation, up to 400-500 eggs are laid out per 1 cm2 of the bottom of the cups, which usually coincides with the size of one clutch.
Moving masonry to the second workshop
If you provide a temperature in the region of 18-20 ° C, then the incubation cycle is 50-70 hours.
Before completion of incubation, which is recorded by the first hatched larvae, 85-90% of the egg clutches should be placed in the second workshop.
The remaining 10-15% of egg clutches should be kept in the same place and not transferred from the first workshop to the second. They will serve to restore the mosquito population.
The egg laying transferred to the second workshop should be distributed into ditches containing liquefied sludge, occupying half the container. The height of the cuvettes is 25-30 mm, and their area is 0.25 m2. At the same time, 50-60 thousand eggs are laid out for each square meter of soil surface, which equals an average of 100-150 clutches of eggs.
After the egg laying is completed, the containers are placed in several tiers in special frames. The gap between the two cuvettes is left at 30-40 mm. Each frame includes 30-40 cuvettes (see Figure 26).
Feeding bloodworms
The larvae that emerge from the eggs can immediately begin to feed, eating the clutch mucus and food added to the cuvettes.
Special yeast, added at the rate of 100 grams per square meter of soil surface, can serve as an excellent food. In this case, the food should be laid out before the eggs are placed in the cuvettes.
Before spreading the yeast, it should be soaked in water to form a semi-liquid dough. After this, the resulting mass is mixed well with sludge.
The nutrient medium created in this way for the larvae makes it possible to grow chironomids for 10-12 days, and only 3-4 days before collecting the grown individuals, another portion of yeast food is added, but now in dry form. This is done by spraying yeast on the ground surface at the rate of 30-40 grams per 1 m2.
Sequence of actions in case of temperature violation
In the event that the temperature in the workshop rises above 18-20 ° C, you should refrain from introducing a significant amount of feed. This is due to the fact that excess feed in such a situation leads to rotting and the release of hydrogen sulfide and methane into the air.
At this temperature, the best solution would be to add feed at intervals of 3-4 days. In this case, the feed portion should be made larger over time in accordance with the growth of the larvae.
If the temperature is at 20-22° C, then you need to follow the following recommendations on the timing and rates of adding yeast feed.
Before feeding, it is necessary to remove excess water from the ground surface. In this case, you should do this especially carefully so that the soil does not dry out. The final feed application is made 72 hours before the larvae are removed.
Collecting bloodworms to feed fish
After the larvae reach a state close to pupation, everything that is in the cuvettes is transferred to a mesh drum located in the washing tank (see Figure 27).
The drum is started using an electric motor or manually. After this, small particles of sludge overcome a mesh with a mesh size of 0.7-0.8 mm and end up at the bottom of the tank.
After collecting the sludge from the drum, the larvae inside are transferred to a bag made of mill silk gas, which is then washed under a stream of clean water. After this, the larvae go to feed young fish.
The sludge found at the bottom of the tank is reused to fill the ditches.
In one day, approximately 2-3 kg of bloodworms are collected from 200-300 m2 of breeding area, i.e. 10 grams per square meter comes out.
To collect 1 kg of bloodworms, you need to consume 0.5-0.7 kg of yeast feed.
Pupa stage for mosquito breeding
The 10-15% of egg clutches left in the first workshop should also be laid out before the bloodworms appear in containers filled with liquefied sludge, placed in multi-tiered frames.
The emerging larvae feed on yeast food at rates similar to those of the second whole.
Before pupation, the larvae should not be removed from the ground, which will allow them to form into pupae and then become mosquitoes.
If comfortable conditions are provided, the larvae become pupae on the 12-13th day after emerging from the testicles.
The pupal stage lasts for 2-3 days.
Life cycle of mosquitoes
The mosquitoes that emerge from the pupae fly away from the ditches and after 20-30 hours become sexually mature, after which they will be able to swarm, reproduce and lay eggs.
The clutch contains nutritious mucus and approximately 400-500 eggs.
Female mosquitoes lay eggs in both dark and light periods.
After laying eggs, mosquitoes die. The total lifespan of a mosquito reaches 3-5 days.
During the specified time interval, female and male mosquitoes have to do without food.
Catching bloodworms
When you decide that the larvae have grown enough to be used as food or bait, you can trap them. The process is quite simple. The water in the pan is carefully removed - only sludge remains. It must be carefully transferred to a sieve. The sieve is then lowered into a large basin or small tub and a circular motion is made. The silt, washed away by water, is simply decanted into the water - the selected larvae remain in the sieve. It was for this purpose that the sludge was washed when it was collected from reservoirs - so that the sludge would not have to be dealt with again with excess garbage. The sludge can be returned back to the baking sheets - it will still serve for further cultivation. After all, if you are interested in bloodworm breeding as a business, the flow of production must be continuous.
In such a case, there is no need to remove all the bloodworms from the baking sheets. But you need to cover them on top with gauze or other dense material that allows air to pass through. But you need to provide a certain space, for example, build a small wire frame. Mosquitoes, having emerged from the larvae, fly for a while and, since they cannot fly away, they deposit the larvae directly in the same pans from which they emerged. After this, the process begins again.
Industrial breeding of bloodworms
Chironomid larvae are a delicacy for fish. To increase fish production in artificial reservoirs, it is necessary to increase the volume of larval biomass, that is, to attract adult mosquitoes. This can be achieved in various ways. Under favorable conditions, larvae hatch from the eggs within a couple of days.
To do this, small overgrown areas (cattails, reeds, reeds) are left in reservoirs. In these places, mosquito swarming will occur during seven or at dawn.
If there is little vegetation, you can use straw from which bundles are made, or frames of branches with mowed grass. Frames are placed on each pond.
To attract the largest volume of mosquitoes, it is necessary to place electric lamps along the ponds, which are turned on at night. But the fry are raised in special pools or trays, which does not allow mosquitoes to breed naturally.
For industrial breeding of bloodworms, it is necessary to organize two workshops, as in home breeding. They must maintain temperature conditions and have lighting. Smoke and foreign odors should not enter the room. Initially, a mother culture is established from a small volume of eggs from a nearby pond. Further numbers will be maintained by artificial breeding. On large farms, breeding takes place in large greenhouses, where plastic containers with nutrient medium and water for the larvae are located.
Growing must be done in exceptionally clean containers and water. This eliminates any possibility of introducing pathogens when feeding fish.
The most affordable material for a greenhouse is film. But practice shows that it is better to use synthetic material, like mosquito nets with a fine mesh. Polyethylene increases temperatures in the summer, which significantly complicates production. The mesh provides good air exchange, which is favorable for the active reproduction of chironomidae. In summer, it is necessary to provide for the possibility of cooling the air in the workshop. Fans are often installed.
Egg cuvettes
Mosquitoes should lay eggs in enamel cuvettes filled with water. Their height should be 40-50 mm, and their area should be 1 sq.m. The containers are filled halfway with water. The female lays eggs at the air-water interface. Externally, the masonry resembles centimeter-long mucus tubes with a diameter of a couple of millimeters. Upon closer inspection, you can see the transverse dotted stripes - chironomid eggs.
Next, each clutch is taken out and transferred to an incubator - a set of earthenware cups with a water level of 50-100 mm. It is important to comply with the loading rate - 450-500 pcs. per 1 sq.cm of bottom. As a rule, there are 400-450 pieces in one clutch.
Transfer of masonry
At a temperature of 18-20 degrees, the incubation period is 60-70 hours. The end of the incubation period will be determined by the first hatched larva. From this point on, it is necessary to transfer 80-90% of the masonry to the second workshop. As before, the remaining eggs will form the population. The transferred eggs are placed in cuvettes with liquid sludge, filling half the volume of the cuvette. Its height is 20-30 mm, area - 0.25 sq.m. For every square meter there should be 50-55 thousand eggs, that is, 100-150 clutches.
After filling the cuvettes, they are placed in several tiers on a special frame. There should be a distance of 30-40 mm between adjacent containers. There will be up to 40 cuvettes on the frame.
For effective breeding, two rules must be observed:
- The ambient temperature should be up to 20 degrees. When it falls or rises, the development of larvae is disrupted.
- The water layer above the silt should be 2 mm. A larger amount of liquid will prevent the supply of oxygen and the larvae may die. You can add water using a sprayer.
Feeding
The larvae begin to feed immediately after emergence. Initially, they eat masonry mucus, and then switch to additional food introduced. For this, yeast is used: 100 g per 1 sq.m. They are added before placing the masonry. To ensure uniform mixing with sludge, the yeast is first diluted in water. The larvae can survive in the created environment for up to 2 weeks, and 4 days before collection it is necessary to feed them with dry yeast: 40 g per 1 sq.m.
Some industrial manufacturers use special nutrient mixtures that are mixed with sludge. For example, in Israel, a number of manufacturers add organically pure chicken manure.
Storage
Now you know how to breed bloodworms at home. But you also need to store it correctly, regardless of whether you are going to sell the larvae or keep it for your own needs. This product is perishable - it cannot be stored for a long time, at best a couple of weeks.
Young bloodworms can be stored in a nylon stocking, tightly tied and suspended in a toilet tank - cold running water will ensure good preservation. But make sure that it does not “overripe” and begin to hatch.
Bloodworms can be stored in the refrigerator for some time - only on the bottom shelf, where the temperature is definitely above zero. Place it on wet newspaper and wrap it up. Wrap the resulting package in another 3-5 layers of newspaper to prevent drying out.
If you plan to store bloodworms for a month or more, the only way is freezing. Yes, in this case it will not be possible to keep him alive. But it is still better to feed aquarium fish with dead bloodworms than with dry food.
