Artificial fish began to be grown for a long time, but this direction reached industrial volumes in the 20th century. One of the breeding methods is swimming pools. This option has certain advantages and disadvantages. Basin economy means a number of features and requirements for the process.
Advantages and disadvantages of fish farming in the pool for sale
Breeding fish in the pool allows you to better control the conditions of detention. This applies to the following factors:
- water flow rate;
- temperature condition;
- hydrochemical regime.
The pool allows you to grow fish all year round, which is important for the profitability of the business, as the sale will be carried out continuously. Proper organization of the process allows you to quickly recoup costs and consistently receive income.
Growing fish in pools allows you to automate and mechanize the process. This also applies to ensuring a sufficient amount of feed, and water purification, and oxygen saturation. With a small basin, one person can handle it.
Another important advantage of the basin is the absence of the need to pay taxes. This applies to income tax, social security contributions and VAT. The Unified Agricultural Tax (CST) is not excluded.
There are some drawbacks to basin fish farming. They relate mainly to the costs of this business. It is necessary to organize a pool, to buy fry and food for them. You will also need a pumping station, treatment facilities. If we compare the basin and cage economy, then the cost of the first is about one and a half times higher.
The disadvantages include the need for legal business. To register a basin, you need to collect a certain package of documents.
What kind of fish can be grown in pools?
As a business, you should choose fish that are unpretentious, resistant to various diseases, and quickly gain weight. It is also important to consider the demand of the population for products.
Usually pike, salmon, carps, perch, and bream are grown in pools. From the point of view of generating business income, it is advisable to focus on the cultivation of expensive gourmet fish, that is, salmon and sturgeon.
You can breed trout in pools. This is quite laborious and requires the participation of a highly qualified specialist. With the competent organization of the process, the costs will be paid off due to the high prices for this fish, which is famous for its taste and is not demanding on the conditions of detention.
Arrangement of a fish growing pool
When growing fish, many factors are important, including the arrangement of the pool. In this case, you must consider:
- Execution material . For artificial ponds, metal or plastic can be used. Preference is usually given to the second option, since metal is more expensive, problematic if configuration changes are necessary and requires regular repair costs. The pool can also be made of wood, concrete or fiberglass.
- The shape of the pond . The configuration of the pool is not important for fish. It can be round, oval, rectangular, square, hexagonal. It is important to consider how convenient one form or another is for the dense placement of fish and for cleansing the pool.
- The surface of the pool . This parameter is important for the quality of life of fish. If the pool has rough walls, then various microorganisms and harmful bacteria will accumulate on them. A smooth surface reduces this risk, in addition, it is much more convenient to clean.
An important point in the arrangement of the pool is the control of water quality. The reservoir is artificial, therefore it is necessary to install a pumping station and cleaning equipment.
The quality of life of fish depends on the quality of water. They vitally need oxygen. Its quantitative content depends on the type of inhabitants of the pool. Carps are enough 4 cubic meters. cm of oxygen per liter of water, and its trout need 1.5-2 times more.
When monitoring water quality, it is important to check its response. A high level of acidity is not suitable for fish, so the pH should be at least 7.
For the life of fish, the iron content in the water is necessary, but its high level leads to respiratory disorders. Stabilization requires active aeration of water, due to which iron is oxidized and precipitates.
It is also necessary to control the carbon dioxide content. It should not be more than 10 mg in one liter.
If the pool is not cleaned in a timely manner, then hydrogen sulfide and methane will form in the water. These gases are harmful to fish.

Amount of investments
In order to calculate the exact amount of investments, it is necessary to draw up a competent business plan. With a successful set of circumstances, you can start your own business by spending about 200 thousand rubles.
The exact amount of investment depends on the scale of the organized fish farming. A small pool can be purchased from about 10 thousand rubles. To grow fish, you need certain equipment, which will have to spend at least 50 thousand rubles.
One of the items of expenditure is the purchase of fry. Per kilogram you need to pay an average of 400 rubles. You need to spend money on food. At least 15 thousand rubles must be paid for one ton.
When drawing up a business plan, it is also necessary to take into account the possibility of unforeseen expenses. Finances may be required to purchase additional fry, treatment, and repair.
Not all purchased fry survive. About 10% of them will die, and of the remaining part, only a third will gain the necessary weight.
Growing fish in the pool can be an excellent business, if you take into account all its components and draw up a competent business plan. The basin economy has both advantages and disadvantages. The right approach will allow you to quickly recoup expenses and reach a stable income.
