SU793530A1 - Apparatus for growing molluscs - Google Patents

Description

FIELD OF THE INVENTION The invention relates to the fishing industry, in particular to devices for commercially growing mollusks, for example, scallops, oysters.

A device is known comprising a support element and perforated tapes fixed thereon with the formation of a nest for size 1, ei of mollusks 1.

The disadvantages of the known collector are the complexity of the design and the complexity of maintenance, the need to attach the collector to the cables stretched between the rafts (buoys), which adversely affects the stability of the structure in the conditions of the sea.

The purpose of the invention is to reduce the complexity of service.

For this, the supporting element consists of a disk with removable radial knitting needles and located on the last carpentries, each of which has an overlay pocket on the upper end and a loop for placing the spokes of the disc in the lower end, while the sockets are placed on the outer sides of the sheet. have a slot.

On fng. 1 shows the device in section, side view; in fig. 2 — node 1 of FIG. one; in fig. 3 - the device, top view; in fig. 4 - spoke, axonometric view; on

FIG. 5 - section with pockets, loop c nests for mollusks, perspective view; in fig. 6 - float, axonometric view.

The device comprises a disk 1 with removable spokes 2 connected by means of a cable 3 with a load (trunk) 4 mounted on the bottom. The spokes 2 are secured by sections of panels 5 made by interconnecting three perforated elastic tapes with pockets 6 at the upper end for accommodating the welds 7. On the outer sides of the panels 5 are nests 8 having slots 9 for placing mollusk yearlings and formed from perforated tapes . Pockets 6 have aprons 10 for fixing the naplavs 7 in pockets 6, which cover the ends of the pockets by welding with the surface of the pockets. Spokes 2 at one end have produn 11, and at the other - turntables 12.

At the lower end of the cloth there are loops 13 for placing the needles 2 therein.

Disc 1. Cloths 5 should be made, for example, of polyethnlene films welded to each other in the longitudinal and transverse directions with the formation of corrugations (nests), surfacing 7 - of peplast, the size of the slot 9 is expedient

comply with the geometric dimensions of mollusk fingerlings.

The device is used as follows.

Mollusk juveniles are laid through slots 9 in the nests of 8 panels 5. The device is installed in the water column. When the mollusks of the mollusks reach the standard size, 5 scuba divers take off the spokes 2 and rise from the water aboard the watercraft where the surfacing 7 and the spokes 2 are removed, and the mollusks packed in this way in plastic wrap are sent to retailers ti. The cycle is repeated. In this case, the same floats 7 and spokes 2 are used each time.

Due to the flexibility and insignificant positive buoyancy of most of the elements and the whole structure of the device, the latter, under the action of external forces, easily changes its spatial position relative to the heeling point, which makes the device resistant to waves, and

four

With a strong flow or swell, the sea elements of the device assume a horizontal position, buried deep in the water.
