Description

This utility model relates to devices used for growing aquaculture facilities under adverse environmental conditions in enterprises using cages for keeping and growing fish.

Known cage for the industrial cultivation of fish with artificial aeration [1], containing a pontoon part with a rail, on which is mounted a net camera. A hollow perforated element is attached to the bottom of the network camera. The hollow perforated element can be made, for example, in the form of a ring covering the net chamber. A nozzle mounted above the water level is attached to the hollow perforated element. Holes are made in the hollow perforated element along the hollow perforated element. The holes have a diameter sufficient to maintain pressure in the hollow perforated element. The holes are located on the inside of the hollow perforated element and directed into the net chamber.

The main disadvantage of growing fish in the known device is that when the ambient temperature rises, the temperature inside the cage also increases, which negatively affects the physiological state and, in turn, leads to an increase in the feed coefficient, a decrease in disease resistance, and an increase in mortality.

A device for optimizing the aquatic environment for cages [2] is also known, consisting of a waterproof frame with valves for removing excess water located in the upper part of the device for optimizing the aquatic environment for cages and a valve for removing waste products in the lower part.

The disadvantage of this device is the complexity of installation and assembly of this design. In addition, a weak aeration of water in the cage is provided, which creates insufficiently comfortable conditions for keeping fish. Cold water is supplied to the cage in such a way that the cooling uniformity is carried out only in the presence of a waterproof frame and is not suitable for open cages.

The closest known analogues is a device for growing fish [3], which is accepted as a prototype. The device for growing fish includes an external cage made of waterproof material, the upper part of which is in the form of a cube or parallelepiped, and the lower shape of an overturned truncated pyramid with a hole at the top, a rectangular overflow hole with a shield shutter in the grooves and a contouring frame located on the side wall external cage on the water edge, the metal tip of the pyramidal part of the external cage with an aperture at the top, plumb loads fixed at the corners of the external cage at the top joint her and the lower parts, an internal cage from a mesh cloth for keeping fish; pontoons for placing the device on a pond, submersible electric pump, water supply hose, water aeration unit.

However, this device has a more complex design and is not suitable for round cages. In addition, the oxygen saturation of the water supplied to the cage in this device is ensured by the aeration unit, which is a more resource-intensive option and provides sufficient aeration only if there is an external cage made of waterproof material. The cooling of the net chamber volume also directly depends on the presence of an external cage made of waterproof material, which is also a significant drawback, since it is not suitable for open cages.

The technical result achieved with the help of a cage for industrial fish farming with optimization of the aquatic environment is that it provides a comfortable fish content within the optimum temperature range and oxygen saturation of the water for it.

The technical result is achieved by the fact that a sprayer is installed at the end of the surface of the hose, directed downward with a spray angle sufficient to cover the entire water surface inside the net chamber, and a holder bar is mounted on the top of the cage to which the surface of the hose with the sprayer is attached.

In FIG. 1 shows a general view of a cage for industrial fish farming with optimization of the aquatic environment.

The fishpond for industrial fish farming with optimization of the aquatic environment, contains a pontoon part 1 with a rail 2, on which the net chamber 3 is fixed. To the bottom of the net chamber 3 are attached elements with negative buoyancy 4, made in the form of weights that keep the net chamber 3 in a submerged state . On the pontoon part 1, a holder rod 8 is installed with its free end directed to the center of the network chamber 3. A hose 6 is attached to the holder rod 8 by the surface part 6. At one of the ends of the hose 6 located in the center of the network chamber 3 a spray gun 7 is installed using the holder bar 8 above the cage so that the spray area covers the entire surface of the water bounded by the net chamber 3. The second end of the hose 6 is lowered into the water and connected to the submersible pump 5. The submersible pump 5 is lowered below the net chamber 3, to a depth where the water has an optimum temperature for keeping fish.

Using a submersible pump 5 set to a depth where the water has an optimum temperature for keeping fish, water is supplied through a hose 6 to a sprayer 7. Through a sprayer 7, water is sprayed into the upper part of the netting chamber 3 over the entire area, saturated with atmospheric oxygen along the way.

Thus, the proposed cage for industrial fish farming with the optimization of the aquatic environment allows to optimize the temperature and oxygen conditions of the cage at the lowest cost, which allows to reduce the growing time, increase the survival rate of aquatic organisms and reduce the feed coefficient.
