Description

Ecological fluorescent fish reef

Technical Field

The invention relates to a fish reef, in particular to an ecological fluorescent fish reef.

Background

The artificial fish reef can be used for gathering and protecting marine organisms. The artificial fish reef is put in, so that the survival and the propagation of marine organisms can be effectively protected, a habitat of the marine organisms is formed, and the biodiversity of the surrounding sea area can be better protected by the animals and plants attached to the artificial fish reef.

Many fishes in the ocean have obvious phototaxis, but the traditional artificial fish reef put in the ocean has no obvious gathering effect on some phototaxis fishes; many artificial fish reefs structure is single, can't accomplish to distinguish effectively the fish of different size of the body, different life habits.

There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

Disclosure of Invention

The invention aims to overcome the defects in the prior art, and provides the ecological fluorescent fish reef which is simple in structure, ingenious in design and reasonable in layout, can effectively gather phototaxis fish schools, and can realize the distinguishing and gathering of fish bodies with different sizes under the condition of not influencing ocean currents.

The technical solution of the invention is as follows: an ecological fluorescent fish reef is characterized in that: the fish reef include base 1, be provided with the whole frame body 2 that is cube shape on base 1, the top of frame body 2 is connected with roof 3, has seted up many recesses 4 on roof 3, and the opening at roof 3 middle part is linked together with the inside of frame body 2, frame body 2 coats outward and is stamped the net piece, the net piece divide into first net piece 5 and second net piece 6 two kinds, is provided with second net piece 6 in the middle part of frame body 2, second net piece 6 separates the inner chamber of frame body 2 for equal two parts, and first net piece 5 covers partly, and second net piece 6 covers another part, and the mesh aperture of second net piece 6 is less than the mesh aperture of first net piece 5 simultaneously, the fish reef still includes four vertical boards 7 along frame body 1 diagonal distribution, the via hole has been seted up on vertical board 7, three side of vertical board respectively with base 1, The frame body 2 contacts with the top plate 3, the fish shelter also comprises four horizontal plates 8 which are respectively distributed at four side surfaces of the frame body 2, via holes are also formed in the horizontal plates 8, three side edges of the horizontal plates 8 respectively contact with the side surfaces of the frame body 2 and two adjacent longitudinal plates 7, the horizontal plates 8 and the horizontal plane support are at 30-45 degrees included angles,

the first net piece 5 and the second net piece 6 are both formed by weaving fluorescent net wires.

Compared with the prior art, the invention has the following advantages:

the ecological fluorescent fish reef with the structural form has the advantages of simple structure and ingenious design, and a special structure is designed aiming at various problems of the traditional fish reef in the using process. Firstly, the inner cavity of the fish reef is divided into two parts by using two meshes with different apertures, the two parts can respectively accommodate fishes with different body types, and a better sheltering space is provided for small fishes; secondly, the net sheet is woven by fluorescent net wires, can automatically emit fluorescence in dark environment, and can effectively attract fishes with phototactic characteristics to gather; the obliquely distributed horizontal plates arranged at the bottom of the fish shelter can construct a relatively dark area at the bottom of the fish shelter, so that reef fishes can be attracted to gather and inhabit; therefore, the protection and utilization of marine environment and fishery resources by throwing the fish reef can be more effectively realized. And the fish reef has simple manufacturing process and low manufacturing cost, so the fish reef has multiple advantages, is particularly suitable for popularization and application in the field, and has wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the accompanying drawings. As shown in fig. 1, 2, and 3: the utility model provides an ecological fluorescent fish reef, includes base 1, is provided with the whole frame body 2 that is cube shape on base 1, the top of frame body 2 is connected with roof 3, has seted up many recesses 4 on roof 3, and the opening at roof 3 middle part is linked together with the inside of frame body 2, frame body 2 coats outward and is stamped the net piece, the net piece divide into first net piece 5 and second net piece 6 two kinds, is provided with second net piece 6 at the middle part of frame body 2, second net piece 6 separates the inner chamber of frame body 2 for equal two parts, and first net piece 5 covers partly, and second net piece 6 covers another part, and the mesh aperture of second net piece 6 is less than the mesh aperture of first net piece 5 simultaneously, the fish reef still includes four vertical boards 7 along frame body 1 diagonal distribution, the via hole has been seted up on vertical board 7, the three side of vertical board respectively with base 1, Frame body 2 and roof 3 contact, simultaneously the fish reef still includes four horizontal plates 8 that distribute respectively in frame body 2 four sides department, the via hole has also been seted up on horizontal plate 8, and horizontal plate 8's three side contacts with frame body 2's side and two adjacent vertical boards 7 respectively simultaneously, just horizontal plate 8 supports with the horizontal plane and is 30-45 contained angle, first net piece 5 and second net piece 6 weave by the fluorescence net twine and form.

The working process of the ecological fluorescent fish reef provided by the embodiment of the invention is as follows: the fish reef is placed on the seabed of a designated sea area, the base 1 is in contact with the seabed, and the first net piece 5 and the second net piece 6 are woven by fluorescent net wires made of fluorescent master batches, so that the net pieces can continuously emit fluorescence in a dark environment, and fishes with phototaxis characteristics in the sea area are gathered at the fish reef;

the inner cavity of the frame body 2 is divided into two identical cavities by the second net sheet 6, and because the mesh apertures on the first net sheet 5 and the second net sheet 6 are different, the cavities covered by the first net sheet 5 can contain fishes with relatively large body types, and the cavities covered by the second net sheet 6 can contain fishes with relatively small body types, so that the structure can effectively protect small fishes;

the four longitudinal plates 7 in the fish reef can not only divide the side surface of the fish reef into different areas to provide an avoiding space for marine organisms, but also can improve the attachment area of marine algae and plants and provide abundant baits for the marine organisms; the four obliquely distributed horizontal plates 8 can provide an attachment area and can build a relatively dark area at the lower half part of the fish reef, so that the reef-like fishes can be attracted to gather and inhabit; and the via hole of seting up on vertical board 7 and the horizontal plate 8 then can let the ocean current pass through, guarantees the upward flow of building that the fish reef can be smooth.
