Abstract

The utility model discloses a bait cultivation type shell concrete reef which is characterized in that the bait cultivation type shell concrete reef is provided with a hollow hexahedron (1) made of concrete; openings (2) are arranged on all surfaces of the hollow hexahedron (1); the two ends of a shell string (3) are connected with the openings (2); and a fastening lug (4) is also arranged on the hollow hexahedron (1). The bait cultivation type shell concrete reef has the beneficial effects that after the field test at the sea area, shells can provide attachment matrixes for attaching organisms such as alga, and the shell string at a window also can change the flow direction and the flow state of a water body, therefore, the shell concrete reef is beneficial for fish to perch in a reef body, wastes are disposed, the cost of building the reef is saved. In addition, the shell concrete reef has the advantages that the structure of the reef body is stable, the manufacturing is simple, the cost is low, etc.

Description

Bait cultivation type shell concrete reef

Technical field:

The utility model relates to a kind of artificial fish shelter, but especially a kind of simple in structure, with low cost, be beneficial to marine product and perch, grow and the bait cultivation type shell concrete reef of twice laid.

Background technology:

Continuous development along with fishery, its natural resources amount obviously descends, people adopt following dual mode for this reason, recover its resource in the hope of propagation: the one, develop on a large scale and propagate artificially, because of the quality deterioration of propagating artificially, the disease that high-density breeding causes takes place frequently, and problems such as the serious and food security of self-pollution have all restricted the development of culturing.The 2nd, artificial fecundation is released.It is to perch the field of living of growth by the suitable marine organisms of the method construction of throwing in artificial fish shelter in natural marine site that artificial fecundation is released, manually living provides feeding ground, sanctuary and can enlarge the food source of marine product by the propagation natural seaweed for marine product, the marine product quality of propagation is higher, thus artificial fecundation to release be a kind of more excellent selection.At present in the fish shelter of throwing in the most approaching natural, cost is minimum is exactly the building stones reefs, thereby effect is reduced even disappearance but buried by silt easily after the input of monolithic work stone, its position can not be adjusted and move according to on-site actual situations, and the big slit of work stone own is less to be unfavorable for perching of marine product.

In recent years because the fast development of shellfishery, bring to the mankind enrich high-quality protein in, the a large amount of discarded shell that is produced is as sanitary fill Cheng Shan, and to the residual body of shellfish on the summer shell more can putrid and deterioratedly give out foul smell, pollute surrounding environment, and it is handled as garbage loading embeading, needing a large amount of financial resource and material resource of cost, cost is higher.

Summary of the invention:

The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, but provide a kind of simple in structure, with low cost, be beneficial to marine product and perch, grow and the bait cultivation type shell concrete reef of twice laid.

Technical solution of the present utility model is: the hollow hexahedron of being made by concrete is arranged, be equipped with opening on hollow hexahedral, shell string two ends and opening join.

The beneficial effects of the utility model are through the sea area field trial, shell can be aufwuches such as algae attaching substratum is provided, the shell string that is in the window place can also change water body and flow to and fluidised form, being beneficial to fish etc. perches in reefs inside, promptly having handled discarded object has saved again and has built the reef cost, have the reefs Stability Analysis of Structures, make simply low cost and other advantages.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment:

Below in conjunction with description of drawings embodiment of the present utility model, as shown in Figure 1: wood is made into mould, be fixed in one with concrete casting, form hollow hexahedron 1, hexahedron is of a size of long 80～150 centimetres, wide 80～150 centimetres, high 80～150 centimetres, all have square aperture 2 on hollow hexahedral each surface, opening 2 is long 50～90 centimetres, wide 50～90 centimetres, the shell that reinforcing bar or the stainless steel wire rope of diameter 3～6mm passes same size is made shell string 3,70～110 centimetres of length, during cement injection, shell string 3 stretching two ends are embedded in opening 2 cement.For ease of operation, when concrete perfusion, set at diagonal two ends, hexahedron top be convenient to fasten input fasten ear 4.

Lay with group in on-the-spot sea area is that unit is thrown in, 2～4 meters of the every capable individual distances of reef group, and 3～5 meters of line spaces, every row is thrown in 50～100 of reefs, every group 20～30 row.

Claims

1. bait cultivation type shell concrete reef, it is characterized in that: the hollow hexahedron of being made by concrete (1) is arranged, be equipped with opening (2) on the face of hollow hexahedron (1), shell string (3) two ends and opening (2) join, and also are provided with on hollow hexahedron (1) and fasten ear (4).
