The invention relates to the fishing industry, in particular to devices for mariculture, and can be used for the commercial cultivation of mollusks (mussels, oysters, etc.) in open sea areas.

The purpose of the invention is to increase storm resistance and ensure stirring at a predetermined depth of the reservoir.

The device allows assembling from unified elements, transporting them to a specified area of the water area, most efficiently using various layers of water to settle

Assembled or in parts, the device is delivered to a predetermined area and installed at least two cores of any design or detached between objects (not shown). At the same time, water through the holes 8 in the lower part of the floats partially fills their internal volume, due to which the floats 4 occupy a vertical position, and the floats 1 are submerged. By supplying compressed air through the valves 10 and I, the buoyancy of the floats 1 and 4 is controlled, the overhanging part of the floats 4 being between 0.7 and 1 m, and the floats of the 1 are completely displaced. After the larvae have settled on the collectors 2

A device for breeding mollusks at depth is produced by changing

consists of a horizontal float 1, with the floatability of floats 4. The device’s depth is periodically monitored on scales 13 and the amount of received ballast water changes as the weight of the mollusks changes.

Upon reaching the marketable size of the mollusks, the ballast water is displaced from the floats 1 and they float to the surface.

collectors 2 attached to it with a spacer element - a load 3 in the lower part, vertical floats 4 with stops 5 in the lower part, 4 clamps 6 freely attached to the floats, to which the float is attached - wok 1.

Clamps 6 are split rings, floats 1 and 4 are pipes made of polyethylene, moballa or fiberglass, with embedded ends.

after which the device can be towed to the shore or the crop is removed on site. Increased storm resistance provided inside the pipes, semipermeable pipes are installed, due to the fact that the device has interrupted baffles (not shown) to reduce the influence of the free surface of ballast water in the floats. In the upper part of the float 1 there are nozzles 7, which are used for feeding and are immersed, the main mass of the device - horizontal floats with collectors fixed on them, is located at a given depth, and the surface of the water is crossed only by vertical floats with

air, regulating the amount of 35 a small area of the existing waterline, ballast water in the float. At the bottom of the hour - Placement of the device at a given

These floats 1 and 4 have 8 holes for ballast water intake.

The fitting 7 is provided with hoses 9 with valves 10 fixed on the floats 4.

the depth is accomplished by changing the buoyancy of the horizontal and vertical floats.

Claims (1)

Claims An apparatus for breeding mollusks, including a horizontal float of adjustable buoyancy and attached headers with a spacer element, characterized in that, in order to increase The floats 4 in the upper part have a valve 11 for regulating buoyancy. The device can be assembled into triangular sections (FIG. 3), of which a company is able to design the necessary configuration (Fig. 4), while fitting 7 neighboring pop. storm tolerance and securing of the benches 1 are connected by a hose 12, and sec- ond at a predetermined depth of the reservoir, it is dosed - between itself horizontal additionally contains vertical floats benches 1.ki with stops in the lower part and freely The device operates as follows, clad on the floats clamps, and horizon. A floating float is attached to the latter. Assembled or in parts, the device is delivered to a predetermined area and installed at least two cores of any design or detached between objects (not shown). At the same time, water through the holes 8 in the lower part of the floats partially fills their internal volume, due to which the floats 4 occupy a vertical position, and the floats 1 are submerged. By supplying compressed air through the valves 10 and I, the buoyancy of the floats 1 and 4 is controlled, the overhanging part of the floats 4 being between 0.7 and 1 m, and the floats of the 1 are completely displaced. After the larvae have settled on the collectors 2 or under adverse weather conditions, air is blown off through valve 10, then the device may be towed to the shore or the crop may be removed on site. Increased storm resistance is ensured by the fact that the device is made immersed, the main mass of the device - horizontal floats with collectors fixed to them, is located at a given depth, and only vertical floats with the depth is accomplished by changing the buoyancy of the horizontal and vertical floats. Claims An apparatus for breeding mollusks, including a horizontal float of adjustable buoyancy and attached headers with a spacer element, characterized in that, in order to increase stability and securing at a given depth of the reservoir, it is up to 9u .2 Fi & W /./ -iVA-LV- / .. ./ ..
