Description

The utility model relates to the field of fish farming, and can be used to obtain planting material for fish ponds, in particular farm fish farms.

The main objective of the production of marketable fish is the stocking of reservoirs with viable material, which reduces fish waste during rearing, ensures the production of large-scale marketable fish in a shorter time, reduces the cost of feed per unit of farmed fish, affects the effectiveness of the process - the percentage of return of marketable and mature fish increases .

Closest to the proposed utility model is, selected as a prototype, the installation for the incubation of eggs and rearing of young fish (patent RU No. 26367, IPC A01K 61/00) including incubation apparatus, containers for growing young fish, a circulation water system that includes connected between each other through pipelines a sludge system, a circulating water system pump, a circulating water purification device, a bactericidal device, a circulating water aeration device, a wind electric generator, a diesel gene ator, a heat exchanger, the thermal energy storage tank with an electric heater, heating-cooling water circulating system consisting of coils pump.

A disadvantage of the known installation is the complexity and cumbersome installation, the high cost of component parts, and hence the high cost of obtaining planting material.

The aim of the invention is to reduce the cost of the installation for incubation and rearing of young fish and simplify its operation.

The technical result is to reduce the economic costs of growing planting material for fish ponds.

The goal is achieved by the fact that in the installation for the incubation of eggs and rearing of young fish, which includes a tank for rearing young fish, an incubation apparatus, circulation pumps, a water purification device, a device for aeration of water, according to a utility model, the installation is located on the shore of a reservoir, as circulation pumps, water purification devices, water aeration devices, two pumps are used, equipped with mud filters, and one of the pumps is installed in a tank for rearing young fish and is connected via a hose to nkubatsionnym apparatus, and the second set in the reservoir and through the hose connected to aquaculture tank.

As a fish tank, a cage located in a pond can be used.

The advantage of the proposed utility model is the use of aquarium pumps in fish growing plants to perform the functions of several devices: fresh water pumps and water aerators. At the same time, mud filters mounted on the pumps serve as water purification devices and at the same time serve as safety devices against the entry of larvae into the pump.

Installing one of the pumps in a pond allows you to use water circulated in the device, which has been defended and purified from bacteria in natural conditions, which allows you to do without a device for disinfecting water. This is due to the fact that a certain equilibrium is observed in nature. Therefore, in vivo, there is no high concentration of bacteria in contrast to artificial reproduction in closed water supply plants, where the ingress of the virus leads to their rapid reproduction and, consequently, to high mortality of fry.

The use of a cage as a fish-breeding tank allows you to grow fish in it in a high concentration, as well as during a period of cold in a reservoir, pumps create aeration zone in the cage.

All this greatly simplifies and reduces the cost of the installation for incubation and rearing of young fish, and this will positively affect the profitability of fish products.

The essence of the utility model is illustrated in the drawing, where Fig.1 shows a block diagram of the installation.

The installation is located on the shore of a reservoir and contains a fish tank 1, an incubation apparatus 2, for example, Weiss, mounted on a stand 3, and two pumps 4,5. The pump 4 is installed in the fish tank 1, equipped with a mud filter 6 and connected to the incubation apparatus 2 through a hose 7. The pump 5 is equipped with a mud filter 8, installed in a reservoir and connected to the fish tank 1 through a rubber hose 9. The fish tank 1 has a level hole 10 to which a hose 11 is connected for discharging waste water into a body of water. The hole 10 is closed by a mesh filter 12 made of a mill sieve, which prevents the exit of larvae into the reservoir. The incubation apparatus is equipped with a tray 13 for the withdrawal of waste water and larvae into the fish tank 1.

Installation works as follows:

Turn on the pump 5 in the modes of pumping water and its aeration. Water from the reservoir, filtered by the mud filter 8, is pumped through the rubber hose 9 into the fish tank 1. The tank 1 is filled with purified and aerated water to the level hole 10. Excess water through the strainer 12 to the hose 11 is discharged into the reservoir. At this time, the eggs fertilized, according to the technology, are laid in the incubation apparatus 2. The pump 4 is turned on in the mode of pumping water. It serves as a pump for pumping water from the fish tank 1 through the connecting rubber hose 7 to the incubation apparatus 2. In addition to the cleaning function, the filter 6 also serves as an obstacle against the entry of larvae into the pump 4. The purified water from the fish tank 1 enters the incubation apparatus 2, where it mixes.

Waste water from the incubation apparatus 2 through the tray 13 is discharged into the tank 1, where it is mixed with fresh water enriched with oxygen. Through the level hole 10 and the hose 11, excess water is removed from the fish tank 1 into the reservoir. At the same time, purified and aerated water enters the tank 1 from the reservoir through the pump 5. This circulation process lasts until the incubation and the release of all the larvae, which together with the waste water from the incubation apparatus 2 through the tray 13 enter the fish tank 1. The larvae are located at the bottom of the tank 1, where they are before switching to active nutrition. After the larvae exit completely from the incubation apparatus 2, the pump 4 can be switched to the mode of aeration of water to improve its oxygen component. The installation goes into the mode of growing larvae and rearing juvenile fish. By decision of the fish farmer, the larvae can grow further in the tank, and can be released into. water. When the larvae are released into this reservoir, they do not experience stressful situations, because the hydrochemical composition and temperature of the water in the pond and installation are the same.

In the event of waste discharge into the water body and its severe pollution, the installation can be temporarily put into closed water supply mode by transferring the pump from the water body to the fish tank.

To obtain planting material at a time when the natural temperature of the water is lower than necessary, both for the final maturation of producers and the development and growth of embryos and larvae, the installation can be switched to closed water supply. The fish tank is installed in a small insulated room, an additional thermoregulation device is connected, which can be used as an aquarium thermostat. Disconnect the pump 5, located in the reservoir, and turn it on periodically to replace the water in the fish tank in the amount of 20-30% per day. The circulation pumping of water in the installation is carried out using a pump 4. Thus, in tank 1 and the incubation apparatus, the optimum temperature and gas conditions are maintained, which corresponds to the natural regime for incubation and rearing of juvenile fish. When the optimum temperature of the water in the pond is reached, the thermoregulation is turned off, and the pump 5 located in the pond is turned on.

In another version of the installation, instead of a fish tank, a cage placed in a pond is used. The cage is made of a frame sheathed with a mesh of mill sieves. The incubation apparatus 2 is mounted on the inner wall of the cage and is equipped with a tray 13 for draining waste water and larvae from the incubation apparatus into the cage. The pump 4, which serves to pump water through the incubation apparatus 2, is placed on the bottom of the cage, and is connected to the incubation apparatus 2 through a rubber hose 7. The pump 4 is equipped with a mud filter 6 to purify the water entering the incubation apparatus and serves as an obstacle against the entry of larvae into the pump. The second pump 5 is equipped with a mud filter 8, located in a pond and serves to supply purified and aerated water through a rubber hose 9 to the cage. The installation works similarly to the first option. During a period of killing in a pond, both pumps are placed in aeration mode. At the same time, an aeration zone is created in the cage, there is a good circulation of water and its purification, which provides favorable conditions for keeping fish of high concentration in the cage.

The use of aquarium pumps with mud filters allows them to circulate water in the installation and saturate it with oxygen, purify water from organomineral pollution, which will significantly reduce capital investment and operating costs for the implementation of this installation, and this will positively affect the profitability of fish products. The aquarium pump is installed and operated in accordance with the instructions attached to it. Thus, the proposed installation with small capex allows you to maintain sanitary standards recommended for the cultivation of aquatic organisms. It is inexpensive, has a simple design, which uses commonly available, standard components, takes up little space, is simple and easy to operate. Launching the installation and maintaining a continuous and normal process for the production of planting material require compliance with simple maintenance and control operations. If the unit is placed in a place where there is no industrial electric energy, it can be connected to an electric current generator. All this allows the installation to be used in small farms with limited staff.
