The porous conservation type arched artificial fish reef is simple in structure, ingenious in design and reasonable in layout, can provide enough sheltering space for fishes, and has enough algae attaching surface area.

Description

Porous maintenance type arched artificial fish reef

Technical Field

The utility model relates to a marine organism field of breeding, especially a porous maintenance formula arch artificial fish reef.

Background

The artificial fish reef is a structure artificially arranged in the sea, and aims to improve the ecological environment of the sea area, build a good environment for the inhabitation of marine organisms, provide places for the propagation, growth, bait making and enemy sheltering of fishes and the like, and achieve the purposes of protecting, proliferating and improving the harvest yield. At present, the construction of artificial fish reefs is widely carried out at home and abroad to repair the habitats and fisheries of offshore marine organisms, and a better effect is achieved. The traditional artificial fish reef has a relatively simple structure, provides relatively less sheltering space, and has relatively smaller surface area for algae to attach, so that the protection and proliferation effects are not obvious. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can provide sufficient space of dodging for fish, and has the porous maintenance formula arch artificial fish reef of the alga attached surface area of capacity.

The technical solution of the utility model is that: the utility model provides a porous maintenance formula arch artificial fish reef which characterized in that: artifical fish shelter including the fish shelter body 1 that is the cube shape, set up a plurality of passageways 2 of dodging that are parallel to each other on the fish shelter body 1, the middle part of dodging passageway 2 is provided with two net pieces 3, forms the juvenile fish between these two net pieces 3 and dodges space 4 to still be provided with arch upper cover 5 at the top of fish shelter body 1, the surface of fish shelter body 1 and arch upper cover 5 all is provided with a plurality of crisscross recesses 6 of indulging violently.

Compared with the prior art, the utility model, have following advantage:

the porous maintenance type arched artificial fish reef with the structure is simple in structure, ingenious in design and reasonable in layout, and the fish reef body is provided with a plurality of through holes, so that the passing of ocean currents is facilitated, a swirling flow is formed, and the flow field effect around the fish reef can be effectively increased. Meanwhile, the hole channel part can also provide a place for fishes and precious marine products to perch and avoid enemy, the cavity between the two net sheets in the middle of the hole channel can be used for hanging eggs when marine organisms lay eggs, and can also be used as a protection net for juvenile fishes, and the juvenile fishes can perch in the hiding space, so that the juvenile fishes are prevented from being caught by large carnivorous fishes. Simultaneously still be provided with many crisscross recesses of violently indulging at the surface of fish reef body and its arch upper cover, the existence of these recesses, very big increase the surface area of the reef body, provide more attached space for the alga, conveniently twine the alga seedling rope on the fish reef simultaneously, more be favorable to the attached growth of alga on the reef body and the construction in algae field. And the artificial fish reef has simple manufacturing process and low manufacturing cost, so the artificial fish reef has multiple advantages, is particularly suitable for popularization and application in the field, and has very wide market prospect.

Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 and 2: the utility model provides a porous maintenance formula arch artificial fish reef, artificial fish reef including the fish reef body 1 that is the cube shape, set up a plurality of being parallel to each other on the fish reef body 1 and avoid passageway 2, the middle part of avoiding passageway 2 is provided with two net pieces 3, forms the juvenile fish between these two net pieces 3 and avoids space 4 to still be provided with arch upper cover 5 at the top of fish reef body 1, the surface of fish reef body 1 and arch upper cover 5 all is provided with a plurality of crisscross recesses 6 of indulging.

The utility model discloses porous maintenance formula arch artificial fish reef's working process as follows: the artificial fish reef is thrown in a designated sea area, and fish or other marine organisms can enter the sheltering channel 2 and also can enter a space between the fish reef body 1 and the arched upper cover 5, so that the purpose of sheltering from enemies is achieved; the net sheets 3 in the sheltering channel 2 can provide a foundation for hanging eggs when fishes lay eggs, and after young fishes are hatched, the young fishes can live in the sheltering space 4 between the two net sheets 3 to shelter from the catching and killing of other fishes;

the transparent channel below the sheltering channel 2 and the arched upper cover 5 is beneficial to the passing of ocean current and the formation of a swirling flow, so that the flow field effect around the fish reef can be effectively increased;

and the outer surface of the fish reef body and the arched upper cover thereof is also provided with a plurality of transversely and longitudinally staggered grooves, and the existence of the grooves greatly increases the surface area of the reef body, provides more attachment spaces for algae and is more favorable for the construction of an algae field.

Claims

1. The utility model provides a porous maintenance formula arch artificial fish reef which characterized in that: artifical fish shelter including fish shelter body (1) that is the cube shape, offer a plurality of the passageways of dodging (2) that are parallel to each other on fish shelter body (1), the middle part of dodging passageway (2) is provided with two net pieces (3), forms the juvenile fish between these two net pieces (3) and dodges space (4) to top at fish shelter body (1) still is provided with arch upper cover (5), the surface of fish shelter body (1) and arch upper cover (5) all is provided with a plurality of crisscross recesses (6) of indulging.
