Abstract

The utility model provides a fish multiplication type artificial fish reef, which is composed of a tetrahedron with a frame structure and a suspension ring. The front, back and left and right of the tetrahedron are completely symmetrical. There is a rectangular window on each of the two rectangular side walls of the tetrahedron. There are many square holes and circular holes on the inner and outer surfaces of the side walls of the tetrahedron. There are two hanging rings on the opposite corners. The beneficial effect of the utility model is that it has the advantages of simple process, low cost, small volume, movable sinking position in the sea, interchangeable seawater inside and outside the reef, etc., and can be widely used for rock-loving fish and sea cucumbers, sea urchins and abalones. The living and reproduction of aquatic animals such as crabs and crabs is conducive to increasing the amount of resources.

Description

A kind of fish multiplication type artificial fish reef

technical field

The utility model relates to the technical field of aquatic animal multiplication tools, in particular to a fish multiplication artificial fish reef, which is used for the habitat and reproduction of offshore rock-loving fish, sea cucumbers, sea urchins, abalones and crabs and the protection of juvenile fish resources.

Background technique

Artificial reefs are structures installed in the sea to improve the ecological environment of sea areas, attract fish, proliferate aquatic organisms, and increase fish catches. In the past, artificial reefs were mainly used to lure fish. They were large in size and single in structure, and they were set in the sea so that they could not be moved. Reduce or lose the fish gathering effect. In addition, the artificial reef has a single structure, and there is no place for fish to lay eggs and young fish to escape from predators, so it cannot play the role of protecting and multiplying fish resources.

Contents of the invention

The purpose of this utility model is to improve the deficiencies of existing artificial fish reefs, and to provide a kind of fish multiplication suitable for offshore rock-loving reef fish, sea cucumbers, sea urchins, abalones, crabs, breeding, and protection of juvenile fish resources. type artificial reef.

The technical solution adopted by the utility model to solve the technical problem is: a fish multiplication type artificial reef, which is composed of a tetrahedron 1 and a suspension ring 5 with a frame-shaped structure. It is characterized in that: the front, back and left and right of the tetrahedron 1 are completely symmetrical, and there is a rectangular window 2 on each of the two rectangular side walls of the tetrahedron 1; there are a plurality of square holes 3 and circles on the inner and outer surfaces of the side walls of the tetrahedron 1. Shaped hole 4; Two suspension rings 5 are arranged on the opposite angle above 1 on the tetrahedron. The fish multiplication type artificial fish reef is composed of a tetrahedron 1 with a cement box structure and a steel suspension ring 4 . Two square windows 2 are provided on the corresponding side wall of the tetrahedron 1, so that the sea water inside and outside the reef can be exchanged under the action of the current; there are a plurality of square holes 3 and circular holes 3 on the inner and outer surfaces of the side wall of the tetrahedron 1. It is used for fish to lay eggs and avoid predators; the top of the tetrahedron 1 is provided with 2 steel reinforcement rings for sinking and moving.

The beneficial effect of the utility model is that it has the advantages of simple process, multiple holes, low cost, small volume, movable sinking position in the sea, exchangeable seawater inside and outside the reef, etc., and can be widely used for rock-loving fish and sea cucumber, Sea urchins, abalones, crabs and other aquatic animals live and multiply, which is conducive to increasing their resources.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Detailed ways

The utility model is prepared with cement, sand, stones and books according to the process of concrete, after being evenly stirred, poured as a whole according to the mold, and is formed at one time with the steel bar suspension ring 5 inserted in the mold. The structure of the fish breeding type artificial reef is realized in this way, the steel bar suspension ring 5 is on the diagonal above the tetrahedron 1 of the frame structure, and the rectangular window 2 is arranged at the center of the two rectangular side walls in the tetrahedron 1 , there are square holes 3 and circular holes 4 inside and outside the tetrahedron 1. The length, width, height and wall thickness of the tetrahedron 1 are 1500mm, 1000mm, 1000mm and 280mm respectively, and the length and width of the rectangular window 2 are 570mm and 420mm respectively; There are 8 caves, and their positions can be referred to Figure 1-Figure 5. The side length and depth of the square cave 3 are both 130mm, and the diameter and depth of the circular cave 4 are both 130mm. Made, the diameter of steel bar suspension ring 5 is 140mm, and the length of suspension ring 5 in the frame is 850mm. site, after 30 days, it will be transported and sunk in the sea. Use a special spreader to sink, hang on the suspension ring of the artificial reef to sink, and place it flat on the seabed. After the utility model is placed in the breeding sea area, some rock-loving fish and aquatic animals such as sea cucumbers, sea urchins, abalones, and crabs can live and reproduce, and the biological resources in the fish reef area will increase, which can form a good artificial fish. reef fishery. It is very effective for improving the ecological environment of sea areas, protecting aquatic resources and multiplying fish.

Claims (2)
