Description

The inventive installation for the incubation of eggs and the cultivation of juvenile fish relates to the field of fish farming.

The installation can be widely used in industrial fish farming, in particular in fisheries with a closed water recycling system for the artificial incubation of eggs and rearing of juvenile fish, especially salmon, located, as a rule, in the mouths of small rivers far from main power supply systems.

Such fisheries, due to the pollution and low water levels of these rivers, use cold artesian water, which without heating systems does not allow creating an optimal regime in the early stages of fish development. This leads to a decrease in the yield of viable juvenile fish in fish farms: 8-10% versus 30% on average in Japanese fish farms. The use of sources of heating of circulating water, especially in the spring, allows to increase the weight gain of fry by 40-50% under normal morphophysiological state and high survival rate of juveniles.

A known installation for the incubation of eggs and the cultivation of juvenile fish, containing incubation apparatus, tanks for growing juvenile fish, tanks for stocking process water and a sludge system for circulating process water with a pump, a fine filter unit, aeration devices and bactericidal devices (description of the invention application No. 323737 / 28-13, A 01 K 61/00, 1981).

The disadvantages of this known installation are, firstly, the high energy consumption and, secondly, the inability to provide optimal conditions for the incubation of eggs and the cultivation of juvenile fish with high viability.

Closest to the claimed installation for the incubation of eggs and rearing of young fish for its intended purpose and the technical result achieved is the installation for incubation of eggs and rearing of young fish, containing a circulation water system and a cooling circuit for circulating water in incubation apparatuses, and the circulation water system includes interconnected through pipelines a sludge tank, a circulating water system pump, a circulating water purification device, a bactericidal device, a device equipment for aeration of circulating water, incubation apparatus with coils placed in them, and containers for growing fish. and the cooling circuit of the circulating water in the incubation apparatus includes the coils of the incubation apparatus interconnected by means of pipelines and the pump of the circulating water cooling circuit in the incubation apparatus (description of the invention to USSR copyright certificate No. 1018604 A, IPC A 01 K 61/00, published May 23, 1983 in BI No. 19).

The disadvantage of the closest analogue to the claimed installation is the increased energy consumption for the operation of the heater and cooler of the circulating water system, as well as for the operation of the cooling unit with an evaporator and a device for circulating water aeration, which makes this installation quite difficult

unattractive for use in fish farms located at the mouths of remote small rivers.

In the process of creating the inventive installation for the incubation of eggs and rearing of juvenile fish, the task was to provide optimal conditions for the incubation of eggs and rearing of juvenile fish in the conditions of autonomy of fish farms with a closed circulating water supply system with the following technical results:

-reduction of energy costs;

-ensuring the autonomy of the fish farming process;

-increase the viability of juvenile fish;

-improving the efficiency of the fish farming process in fish farms with a closed system of reverse water supply.

The problem is solved, and the indicated technical results are achieved by the implementation of the claimed installation for the incubation of eggs and rearing of fish fry, containing a circulation water system and a cooling circuit for circulating water in incubation apparatuses, the circulating water system including a settling tank connected to each other through pipelines, and a circulation system pump water, circulating water purification device, bactericidal device, circulating water aeration device, incubation apparatuses with coils isolated in them and tanks for growing juvenile fish, and the cooling circuit for circulating water in incubation apparatus includes interconnecting coils of incubation apparatus and a pump for circulating water cooling in incubation apparatus, while the unit is equipped with a wind generator, diesel a generator, a heat exchanger with a coil placed in it, an artesian water tank with a coil placed in it, a thermal energy tank with the coil and electric heater and the heating-cooling system for circulating water, including the artesian water tanks coil connected to each other, the heat storage tank coil, the circulating water heating-cooling system pump and the heat exchanger coil, the device for circulating water aeration being made in the form air atomizer located in the heat exchanger of the circulating water system, and the cooling circuit of the circulating water in the incubation apparatus A closed artesian water in the container.

The installation works as follows.

When deviating from the specified ranges of values of at least one of the parameters of the circulating water in the incubation apparatus 20 or in the tanks 24 for growing juvenile fish, a pump 14 is turned on, which ensures water circulation in the circulating water system 11.

When the water temperature is lower than the permissible limits in the hatching apparatus 20 or in the tanks 24 for growing young fish, the pump 31 is turned on, the isolation valves 32 and

33, the isolation valves 34 and 35 are closed and the water heated in the coil 9 is pumped through the coil 17, giving off heat to the water circulating through the heat exchanger 16.
