How to grow red fish at home?

Having approached the formation of the pond correctly, having studied the parameters of the water and preparing everything for the launch of the fry, the owner will be able to grow the fish to the optimal size. Careful care and cleaning of the artificial reservoir will increase the number of fish for sale, and therefore increase the amount of profit.

At the moment, many experts in the field of fish farming consider the fish business to be quite a promising direction. Therefore, creating conditions for its development can solve the problem of providing the state with fish and help fish farms in such a difficult task as growing various fish species.

Previously, it was popular to breed fish in artificial reservoirs, but in this case, poachers prevented the growth and development of young animals and grown-up individuals, it is for this reason that fish breeders began to engage in organized reproduction and raising fish on mini-farms and at home. But in order for fish breeding to be successful, a novice fish farmer needs to study the breeding instructions and adhere to all the prescribed rules. Without what, domestic fish farming will not bring the desired results?

Home fish farming from scratch

The most important resource for raising any type of fish is water. The growth, development and health of young animals will depend on its quality.

Step one. Creation of an artificial reservoir.

Before proceeding with the creation of a pond, it is necessary to devote time to a complete analysis of the water, having studied all the indicators and quality standards necessary for settling the reservoir with new residents.

For this purpose, it is best to contact Surveillance and ask specialists to carry out the necessary analyzes of the aquatic environment and give advice on improving it, if necessary. If the water quality is not up to standard, do not despair. It is enough to carry out aeration and cleaning of the pond and everything will return to normal.

Step two. Determination of the quality of water resources.

The water in the fish pond must necessarily have the following characteristics:

• Optimal salt ratio;
• Regular and irregular temperature conditions;
• The total number of microorganisms living in it and PH;
• General transparency;
• The presence of minerals necessary for future fish;
• Color qualities;
• The ratio of gases dissolved in water;

If all these characteristics correspond to the declared standards, then it will be possible to grow fish without any problems.

Step three. Launching fry.

Before you start the fry into the reservoir, you need to know what temperature regime is suitable for the fish species you have chosen. There are fish that are more suitable for cold water, and there are fish breeds that will only feel comfortable in warm water.

Cold-loving breeds include grass carp, carp, catfish, crucian carp, sterlet, silverheads, trout, peled and salmon. Heat-loving fish need to ensure the water temperature is not lower than twenty degrees, and for those who prefer cool waters from ten to twenty degrees. Wintering in the reservoir will also be determined by fish species.

Step four. Stages of fish growing.

In order to properly build your mini fish farm, you need to know that breeding stages are taken into account when growing fish. First, the fish spawn, then fry appear, then the wintering stage follows, the next stage of growth, and experienced fish farmers consider the feeding stage as the last step.

Taking them into account, it is possible to clearly distinguish between these periods and create the necessary scheme for the growth and development of young animals and reared individuals. For each of these stages, it is best to equip your own pond or use plastic pools.

In the pool or pond for spawning, fish farmers are engaged in removing fry from eggs. The hatched fry are transplanted into a pond where they will grow. Upon reaching a certain age, they are placed in a growing reservoir, where they will gain weight. When the generation gets stronger and it will no longer be possible to worry about its health, it is transferred to a feeding pond, but for wintering a special wintering reservoir is used with conditions appropriate for fish.

In order for the fish to grow and develop well, the water in the reservoir must be clean and enriched with oxygen. Also, it should not contain hydrogen sulfide and methane. To avoid their appearance, the pond must be created in an appropriate area, which can be determined using a geodetic map. Also in the reservoir there must be appropriate vegetation, which will saturate the water with substances useful for fish.

Step five. Feeding.

Not only does water play an important role in fish farming, but also the use of appropriate feed additives. In order to grow healthy fish, it is necessary to use feed mixtures appropriate for each breed. They consist of fats, fiber, legumes, grains, proteins, minerals and vitamins that fish need. The secret of success is simple: in order for the fish to grow well, fish farmers fertilize the reservoirs and mineralize them.

For each age of fish, it is necessary to use its own feed additives, as well as to raise immunity, use therapeutic and stressful feed, which helps the fish to cope with the disease and gain immunity to it. That is, in principle, all that is necessary to know for fish farmers who decide to grow fish at home.

Fish farming as a business at home

The most important thing for growing fish is water, without it it will simply not be possible to breed any of the fish species. It is for this reason that, before deciding to grow fish at home, it is necessary to build a suitable artificial reservoir for it.

For this purpose, you can rent a state reservoir, but this idea is better left. Because it will take you a lot of time to obtain various permits and approvals, and in addition to all this, your "fishing spot" will also be threatened by poachers trying to catch as much fish as possible in your reservoir. For this reason, it is best to forget about renting a pond from government agencies. Moreover, the cost of a business based on state lease will be very expensive for you.

Another option is to create an artificial pond in your country or summer cottage. The creation of an artificial reservoir will also cost a lot, but it will still require much less material and nerve costs from you, and you will also be one hundred percent sure of the reliability of your business.

If you want to breed fish for which fresh water is good, then you can use a polycarbonate greenhouse with a plastic pool installed in it.It also needs to purchase compressor and filtering equipment, which will cost the lack of three thousand dollars. If you can create such equipment yourself, you can significantly reduce the cost of equipment for the reservoir. But before you start creating or purchasing it, you need to find out what kind of equipment and materials you need.

Equipment for the reservoir

Purification of water in a reservoir should be carried out using a gravity filter. It is quite simple to install and it will not take much of your time. It costs about five thousand rubles. It is used not only for water purification, but also allows you to remove microorganisms that cause water bloom and the appearance of mud.

In order to saturate the water with oxygen, compressor equipment is used. Its cost can reach ten thousand rubles. In order to prevent the water in the reservoir from blooming, sterilizers with ultraviolet diodes are used. To pump water out of the reservoir, you need to purchase a hydraulic pump (about five thousand rubles). You can also do it by yourself collecting it from the tubes. In this case, the reservoir will be filled with water from underground sources and springs. Feeders can be purchased at tackle stores. Also, do not forget about the drainage equipment.

Costs and technology of fish farming

The benefits of fish farming are clear. On the market, take, for example, a sturgeon, a kilogram costs about two hundred rubles. Buying fry or breeding them yourself, you can get up to a ton of fish per year, which is about one and a half thousand kilograms, which means three hundred thousand rubles.

Having spent one hundred and fifty thousand on your fishing business, you can work out the costs for a year and still make a profit. The main thing is to find points of sale and then you don't have to worry about profit.

Of course, only those people who understand all the risks and are ready to take them can engage in fish farming, because this type of business is quite competitive. And if you are not ready to fight and breed really high-quality and selective fish, it is better not to start it.

And now, finally, you have made a firm decision to create your own fish farm. What documents do you need? Since you will be starting a business, you will need to register your business. This will also require additional costs. You will also need a license to grow fish, which you will need to issue. And when you get the first "harvest", you still have to go through product quality control and obtain special permission from the relevant structures.

What is the best fish to breed?

While the cost of creating an artificial reservoir is easy to calculate, the cost of purchasing and raising fish is very difficult. It is for this reason that a clear business plan must be drawn up.

The most unpretentious fish in food and maintenance is carp. It is also affordable and affordable. When purchasing a ton of carp fry, you will need to spend about a thousand dollars. Moreover, this fish breed will not begin to multiply immediately, but only after three years. In addition, in the cold season, carps grow twice as slow.

In industrial terms, the most profitable fish species are considered to be all varieties of sturgeon. An adult sturgeon weighs an average of five hundred grams. A kilogram of sturgeon at wholesale will cost about ten dollars. In your artificial pond, you can grow about a ton of such fish in six months. And this means that this business can really be called profitable.

Growing fish at home on a mini-farm: how to organize it correctly?

If you follow all of the above tips, then growing fish in your pond or pool is not a problem.This is exactly what the farmer Mikhail Atamanov does, who grows sterlet and trout on his farm in Yaroslavl. He grows and sells up to ten tons of fish per year and is not going to stop there. According to him, such a business brings him not only tangible profit, but also pleasure.

In our economically difficult times, many are trying to find alternative sources of income. And if you are one of them, you may be interested in your own fish farm. And for this it is not at all necessary to have a pond or a lake in private ownership. A small pond is suitable for this. You can dig out a pond for fish farming yourself. Of course, in this case, you will not get big profits, but you will always be able to provide your family with fresh produce. And this, you see, is important. Growing fish at home does not require large expenses, so people can do it even with a small start-up capital. Fisheries technology is akin to animal husbandry: in order to get a good result, it is necessary to create comfortable conditions for aquatic animals. This article will describe some recommendations for growing carp, crucian carp, carp. Fish farming in the country is quite real!

To start with it?

At first glance, fish farming at home is not easy. But this is only at first glance: of course, there are some nuances here, but after overcoming the first difficulties, you will understand that everything is not so difficult. Of course, this venture requires a free area, not necessarily very large. Depending on how many pets you are going to settle in the reservoir, calculate its area and depth. You will also have to purchase fry. If this is not possible, then you can independently catch several individuals during the spawning period. Just remember that in this case the final stage of growing will take a little longer. And yet, the temperature of the water in your reservoir should be exactly the same as in the natural one. Otherwise, the fish will die.

What breeds should I give preference to?

Not sure which fry to start? Before organizing fish farming at home, carefully familiarize yourself with the life features of those species that you would like to see in your pond, and later on the table. If you do not want to bother too much in this matter, then preference should be given to carp, crucian carp, carp, bream, tench.

Features of each type

Tench is a very shy fish, so if the choice fell on this particular breed, then take care in advance of a reliable shelter for pets. Lay out a house out of stone and branches where the fish can take refuge. And if the conditions of detention are met, then the fish will gain about two hundred grams in weight a year. Do you think tench grows very slowly? Pay attention to the carp. In practice, it turned out that fish breeding at home becomes more effective if crucians or carps are put into the pond. They grow much faster and are unpretentious in care. These representatives of cyprinids feed on almost everything: algae, insects, porridge, earthworms. This is their favorite food.

Some nuances

You should pay attention to the following fact. Year-round cultivation in self-dug ponds only makes sense when you have the opportunity to leave the fish for the winter. For this, the reservoir must be deep enough, otherwise the water in severe frosts will freeze to the bottom and aquatic inhabitants will die. If the conditions of keeping do not correspond to the optimal ones, release the fish into the pond for growing in the warm season: April – November.

Feeding features

Of course, in order for the fish to gain weight faster, it must eat well. And for this, the temperature in the pond must be high enough. It is advisable to feed the fish at the same time, then carps and crucians will be waiting for you at the appointed hours.Give steamed grain, small insects, worms as feed. If funds allow, you can buy ready-made fish mixes. In the presence of a small reservoir, it is better to make a pallet with sides made of galvanized iron, which can be taken out of the water. It is more convenient to sprinkle food on it, and besides, you will be able to observe the intensity with which your pets eat. In the hot season, watch the water level, if it starts to fall, you will have to reduce the number of inhabitants of the pond. You can determine this by how carps behave: if they float to the surface and gasp for air, then there is not enough oxygen in the water. For a favorable existence, crucians and carps need a water temperature of twenty-twenty-seven degrees. You will have finished products for the third season. Now you know that fish farming at home is a painstaking, sometimes difficult business, but very interesting, and most importantly - profitable. Of course, a good result will be influenced not only by your efforts, but also by the weather conditions. Any seasoned fish farmer will tell you that you can adapt to anything. And then there will always be fresh fish on your table. And you can always easily sell the surplus on the market. Those who are interested in growing fish at home can only wish good luck!

Today, many experts agree that the development of the fish business as such is a very, very promising direction. The creation of conditions for these purposes is the "golden mean" that can largely solve the problem of state provision of food. In the case of fish farming in artificial conditions, uncontrolled fishing and poaching are replaced by organized fish farming on an industrial scale. But in order to start doing this strategically important craft, novice fishing business executives need to learn a certain number of rules, the observance of which will allow them to create an effective action plan and answer the question of how to breed fish at home.

Undoubtedly, the most important criterion for the existence of a reservoir as such is water.

Construction of an artificial reservoir for fish farming

Immediately before construction starts artificial reservoir it is imperative to carry out a comprehensive analysis of the water quality for compliance with official fisheries regulations.

To do this, you need to contact the nearest SES and order a comprehensive event there for the study of hydrochemical, toxicological, bacterial and parasitological water samples taken exactly in the place of the intended reservoir. It happens that the quality of the water does not meet the fishery standards, but this is not a reason to give up. In such cases, possible methods of water treatment are determined, such as aeration of water resources, general purification of a water source, and others.

Water quality in fisheries

In general, the quality of water in fish-breeding reservoirs is determined by the following characteristics:

- regular / irregular temperature;

- general transparency;

- color qualities;

- the ratio of dissolved gases (oxygen, carbon dioxide, hydrogen sulfide, ammonia);

- the presence of organic substances and biogenic elements such as phosphorus and nitrogen;

- total number of microorganisms, pH - pH;

- salt composition.

As you could already understand, an artificial stocked reservoir and fish farm - This is the same. Due to the correct organization of fish farming in artificial conditions, the maximum result is achieved: fish farms are never left without work and, accordingly, without income. Without causing any damage to natural fish resources, fish farms are able to solve many problems of a strategic, national and even global scale.

This fact is already finding its confirmation in the West, where this type of farming has been justifying all the hopes placed on it for many decades. The availability of jobs, the improvement of the country's food base, an increase in trade turnover, a positive environmental effect, etc. - all this is achieved with the intensive and comprehensive development of fish farms.

Reservoir stocking rules

Before launching fry into a pond, you should inquire about the temperature preferences of a particular fish. All fish breeds grown under artificial conditions are divided into heat-loving and cold-loving.

The first group includes fish such as carp, crucian carp, grass carp, silver carp, catfish and others. The group of cold-loving fish includes, in particular, salmon: salmon, trout, peled, sterlet, whitefish and others. For thermophilic fish species, the most favorable conditions for growth are at a temperature of 20-30 C, and for cold-loving species - at 10-20 C. The very possibility of life in reservoirs in winter is determined by the properties of water in a stocked reservoir.

For example, experienced fish farmers know that water has the highest density at a temperature of 4 C. But at the freezing point of water, at 0 C, water has a lower density. That is why ice forms on the surface of the reservoir and protects the reservoir from its complete freezing. In this case, nature has thought of everything and without human intervention.

Breeding stages of fish

In order to choose the right strategy for building a fish farm in advance, you need to know that there are several stages of fish farming in commercial fisheries:

- spawning stage

- fry stage

- wintering stage

- growth stage

- feeding stage

Thus, on fish farms, a clear delineation of the periods of fish development is achieved. In spawning reservoirs, they are engaged in the fact that larvae are removed from the eggs, then they are successively transplanted into the fry, nursery and feeding pond. From spring to late autumn, the grown up, strengthened young generation lives in feeding ponds.

With the arrival of winter, young fish are transferred to a special wintering pond... In general, by the end of autumn the fish is able to reach the required marketable weight and can be successfully sold.

The main feature of an excellent fish pond is the presence of a variety of biological processes and their complete control. That is, in artificially created reservoirs, they not only grow fish or other inhabitants of fresh water, but also independently set the necessary course for these biological processes.

The main indicator of good control in relation to a fish farm is clean, oxygen-rich water in the reservoir. To maintain a favorable microclimate, you need to take care of the absence of methane or hydrogen sulfide in the water.

To do this, it is best to initially ask the relevant services for geodetic data of the territory. If possible, it is better to hire specialists on your own and conduct a geodetic survey of the area.

In addition to all this, for the most favorable development of fish, many trace elements and minerals, such as phosphorus, potassium, calcium, nitrogen, etc., must be present in the water. This is achieved with the help of seedlings of special species of algae, as well as with the help of artificial enrichment of the reservoir with useful substances. This is what specialized firms are doing today.

In general, in order for the living conditions of a fish farm to meet all modern standards, one simple mechanism must be understood: everything in a pond must be interconnected in a circular pattern.

After all, everyone knows what the synthesis process in nature is? For those who have forgotten the school curriculum, we recall that synthesis is the exchange of energy between living organisms, which initially enters the earth through the sun's rays.

The same should be strived for when creating and operating a fish farm: all living organisms in a reservoir should be interconnected by natural processes.

How to feed fish in a pond

With intensive cultivation of fish in artificial conditions, you need to constantly monitor the feeding of the fish.

For these purposes, farmers resort to using special feed mixtures, which are purchased through dealers or directly at the manufacturing plant. The fish feed contains only natural ingredients such as legumes, grains, bran, oilcake, as well as some components of animal protein origin.

In order to enrich the natural fodder base of a fish farm, you can resort to general water fertilization and amelioration of the reservoir. The most intensive methods of fish farming in artificial conditions is fish farming in cages and pools.

Feeding your fish should be taken more than seriously. It should be clearly understood that there are separate special feeds for larvae, juveniles and adults of producers.

To increase the immunity of fish, fish farmers resort to the use of special feeds, which are called medicinal stress feeds.

In addition to the intensive, there is also an extensive method of fish farming. In these cases, the farmers resort to natural fish nutrition, without the use of any additional feeding.

Sturgeon fish stock

For any method of growing fish in artificial conditions, the availability of high-quality fish stock is also considered a guarantee of success.

Fish seed is understood as the process of biological cultivation of eggs, which is under the full control of specialists in narrow industries. So, thanks to the high level of selection and breeding work, it is possible to significantly increase the overall efficiency of fish farms.

This method allows from the very beginning to replace a manufacturer with low productivity characteristics with a manufacturer with the required quality.

For the same purpose, a special reserve fund of fish planting material is created, which, in unfavorable conditions, compensates to one degree or another for the losses that were caused to fish as a result of difficult wintering or other circumstances.

As a worthy example of the prospects and opportunities for fish farming, one can cite the fact that scientists of the Southern Scientific Center of the Russian Academy of Sciences for the first time in the world received valuable black caviar of sturgeon fish species that are grown in artificial conditions. Moreover, this unique technology in all respects allows not only to preserve the life of sturgeons and accelerate the process of raising valuable fish species by up to three to four times, but also to take an important step in preserving the so-called “Red Data Book” species.

Getting sturgeon caviar at home

Under artificial conditions, it is possible to obtain caviar from such a species of sturgeon as sterlet.

Thanks to the same innovative developments, this process today takes two years, although in natural conditions the sterlet is capable of “milking” by about the fifth year of its life, and some sturgeons spawn only after 12-15 years, when they reach sexual maturity. Almost the same applies to beluga, which in artificial conditions is capable of producing eggs twice as fast as in the wild. But in general, there is nothing super difficult in the task of obtaining caviar in artificial conditions. For a good result, it is enough to create and maintain optimal conditions in the aquatic environment: water temperature, oxygen content, hydrochemical characteristics, etc.

Milking sturgeon in artificial conditions is far from a simple technological process. To get sturgeon caviar, you need to treat fish like a milkmaid treats a cow.

Stroking and massaging the abdomen, patting the mother by the ichthyologist, and gentle words will not hurt either. Experts say that with this approach, the amount of black caviar will exceed all expectations. After milking, part of the eggs is sent for sale, part is frozen in cryochambers, and part is fertilized, after which the fertilized eggs are transferred to the “fish incubator” using a conventional sieve, in which they have to stay for several weeks.

By the way, after young individuals grow up, many farmers introduce microchips to them and only after that they are released into adulthood. This allows scientists to control the situation and once again rejoice in the effectiveness of their technologies.

Modern methods of fish farming in artificial conditions were developed and implemented taking into account the realities of today. In other words, during the development, absolutely all criteria were taken into account that can affect the cost of the final product.

So, for example, a closed water supply cycle, a balanced three-time diet, divided by seasons, temperature regime, light regime, as well as the speed of water flow in artificial reservoirs, was developed.

The technology developed by scientists of the SSC RAS ​​is now used both in small farms and in large industrial production. This method allows for one year to receive marketable products weighing from 1.5 kilograms per unit, and in two years - fish weighing 3.5 kilograms. In general, food caviar is obtained in 3-4 years of effective work. One of the "secrets" of such a rapid rate of development of fish in artificial conditions is the fact that scientists artificially create several years and winters for fish during one year.

So, the main conditions accompanying favorable fish farming in artificial conditions are the general water quality, diet and diet, as well as temperature and light conditions.

Any violation of these norms can lead to a slowdown in growth, as well as cause disease and death of fish.

For the most correct selection of equipment, as well as the mode and method of feeding the fish, you first need to decide what kind of fish you are going to breed.

salmon and trout farming

Yes, I remember those times when salmon was a luxury for many people. But today it is quite rapidly transforming, and in many countries it has long been turned into the most common everyday food. And all this happens due to the intensive development of Atlantic salmon mariculture. Pond fishing is one of the most popular fish farming industries. It is the cultivation of red fish that has long competed with conventional fishing.
Consider breeding red fish using salmon as an example. Gourmets believe that the best salmon is the one that grew in the cold fjords off the coast of Norway. Today, catching this fish in the wild has become almost legendary for a long time. Indeed, in Norway itself, where fish farming is very common, 70% of salmon is grown in ponds. In Russia, the technology of breeding red fish in ponds is not very popular, since there are still many reserves in the North and Baltic Seas.
Salmon fish are distinguished by their elite dietary meat and, moreover, by their red caviar. Strange as it may seem, but 80% of this delicacy is supplied to Russia from the Far East. That is why the creation of salmon farms remains a young and promising area of ​​farming in the future. Today, by drawing up a well-thought-out business plan for breeding salmon fish, you can earn a considerable income.
Converting wild ponds into fish breeding grounds is not easy. Future farmers will either have to privatize them or rent them. It should be borne in mind that salmon are very sensitive to environmental changes.Plus, in order to popularize such types of fish farms, it is necessary to introduce initiatives, hold competitions between existing farms. In other words, show the state your capabilities. And it, in turn, can attract investment.

In total, there are 20 species of trout, but most often in our climatic conditions 2 species are bred:

• pestle (stream),
• rainbow; Several highly productive subspecies are popular: the deep-sea Canadian camloops and Donaldson's trout, their growth rates are 2 times higher, and their fertility is higher by all 30%.

Both species are predatory, which is reflected in their diet: beetles, dragonflies, frogs, small fish varieties (verkhovka, ide, minnow).

Growth can be characterized by the following numbers:

• up to a year, the mass of fry does not exceed 30 g,
• the weight of one-year-old fish is from 100 to 125 g,
• weight of 2-year-olds - from 200 g.

In Russia, salmon (salmon) farming is not yet developed, since the technology of its cultivation involves the use of laboratories and other rather expensive technologies. But trout farming is gaining momentum.
For pond breeding of trout, sufficient areas and regulation of temperature regimes of water are required. It is important to note that trout, like all salmonids, feeds well and grows in winter and summer. The fish productivity of trout ponds reaches 1000 centners per hectare. The most common species for cultivation are rainbow trout and brook trout.
For trout fish farms, the best are springs with a constant water temperature (springs, streams, small rivers). Trout farms are divided into full-system and non-full-system. The first ones breed trout from their own producers. At the same time, the farm must maintain its own production herd aged 4 - 7 years and their replacement 1 - 2 years.
The main thing in salmon fish farming (especially trout and salmon) is the availability of sufficient oxygen in the water for rapid metabolism and growth.

variety of salmon

Having decided to start breeding trout at home, you need to clearly decide where the fish will be kept, there may be several options:

1. Breeding trout in ponds

When creating an artificial reservoir, you can use clay. You need to fill the pond with fresh water, but ideally, you need to ensure the supply of fresh artesian water. A necessary moment is the organization of the "old" water runoff. To do this, you can use treatment systems or initially design special drainage wells. It is difficult to control the temperature of the water, but for the successful growth of fish, it is necessary to prevent the temperature from dropping below 1.5 ° C.

2. Breeding trout in salt water

The difference from the previous version is that salt water is used. It is recommended to gradually switch to seawater. In fish in such water, the metabolism in seawater increases, therefore, growth rates are accelerated.

3. Breeding trout in swimming pools

To save yourself the trouble of building a trout pond at home, you can purchase a special pool (h

Trout will not breed on their own in captivity, so you will have to engage in artificial insemination. This can take place according to the following scheme:

1. during the spawning period, the best mature producers are selected, they are placed separately;
2. when the eggs of the females are ripe, they need to be separated, for this the female is wrapped in a clean cloth and the eggs are carefully squeezed into a clean container;
3. then strain the sperm onto the eggs, gently stirring it (a bird's feather is suitable for this);
4. add a small amount of water;
5. leave the eggs alone for 5 minutes, during which time fertilization should occur.

It should be taken into account that if eggs are removed from immature females, the percentage of fertilized eggs will be low.

In trout farming on a large scale, for a more comfortable collection of eggs from females, selected producers are given anesthesia.They also practice the use of various stimulating solutions to increase the proportion of fertilized eggs, for example, Hamor's solution.
