Description

Assembled artificial fish reef and fish reef throwing method

Technical Field

The invention relates to the technical field of artificial fish reef construction, in particular to an assembled artificial fish reef and a fish reef throwing method.

Background

The artificial fish reef is constructed by manpower under the water surface or under the water bottom, and the engineering can be used for improving the inhabitation environment of marine fishes or other aquatic organisms, providing the sites for foraging, breeding, growing and developing and the like for various aquatic organisms and the like, and achieving the protection of wild fishes and other aquatic organisms or the improvement of the fishery production capacity. The use of modern artificial fish reef, along with the continuous development of artificial fish reef construction, research such as environmental function, the fish gathering effect about the fish reef is proposed gradually to through the construction of artificial fish reef district, the ecological environment of traditional fishery habitat has obtained improving and restoring, and fishery resources have obtained the recovery, and the quality of economic aquatic products has obtained the promotion, and modern artificial fish reef is also widely used.

The invention discloses an artificial fish reef device (CN 109699549B) with ecological synergy, which can be combined with culture equipment such as a deep water large-scale net cage and the like, and can accelerate the circulation of bottom water body while generating upwelling, provide fresh and sufficient nutrient substances for the interior of the artificial fish reef device, so as to lure fishes, provide excellent habitat for precious marine products such as sea cucumbers, abalones and the like, take away biological metabolism residues and improve the utilization rate of biological substances and energy of the culture equipment such as the net cage and the like. However, the frame structure of the device cannot realize the stability of the device when facing the scouring of sea water and sea waves, is very easy to damage the device, and cannot well enable marine organisms to have a proper habitat.

Disclosure of Invention

The invention provides a method for putting an assembled artificial fish reef, and aims to solve the problems that the conventional fish reef is heavy, has relatively large volume and consumes a large amount of manpower and material resources in the putting process, and the put fish reef has larger surface area for inhabiting attached organisms or semi-attached organisms in the sea.

The invention also provides an assembled artificial fish reef, comprising:

the first fish reef assembly is provided with a semi-floating piece, an upper hollow cavity and a lower hollow cavity are arranged in the semi-floating piece, the inner space of the upper hollow cavity is larger than that of the lower hollow cavity, a circulation hole is formed in the middle of the semi-floating piece, the semi-floating pieces are linearly arranged and connected through rope bodies, the first fish reef assembly is further provided with four side frame bodies, one side face of each side frame body is fixedly connected with the semi-floating piece arranged on the periphery through the rope bodies, and the end parts of the four side frame bodies are fixedly connected end to end through chains to form a rectangular area;

the side frame body is provided with a frame structure, a plurality of auxiliary pieces are arranged inside the side frame body, each auxiliary piece is provided with a polygonal column structure, and the side surface of each auxiliary piece is inwards sunken;

on one hand, when the fish reef is thrown into the sea, flow states such as upwelling, accelerated flow and sluggish flow can be formed on the periphery and inside of the fish reef, so that the phenomenon that the partial stress of the semi-floating pieces in the side frame is uneven due to the flow states is avoided, and after the fish reef is thrown, the fish reef is located below a sea level all year round and is influenced by the disturbance of nearby waves and seawater corrosion, so that the damage to parts in the fish reef is easily caused, for example, a plurality of semi-floating pieces are connected through a rope; on the other hand, the side frame body can also control the distribution range of the semi-floating pieces, and can protect the side surfaces of the semi-floating pieces arranged in the array to avoid the collision of ships and ocean floating objects; on the other hand, the auxiliary parts in the side frame bodies can further provide inhabitation space for marine organisms, and the arrangement of the side frame bodies and the auxiliary parts in the side frame bodies can slow down the flow velocity of nearby water flowing through, further reduce the possibility that the whole first fish reef assembly can move in a large range in water, and effectively prevent a large amount of fixed and semi-fixed organisms such as algae, shellfish and echinoderm attached to the surfaces of the side frame bodies from falling; on the other hand, the first fish reef assembly forms a local shading area below the water surface through the semi-floating bodies arranged in the array, so that a habitat space is provided for the shading organisms;

the semi-floating piece can provide buoyancy for the semi-floating piece, and the larger upper hollow cavity chamber can generate larger buoyancy, so that the semi-floating piece cannot be easily turned over by sea waves and other large marine organisms, so that the marine organisms attached to the semi-floating piece fall off, and the fish shelter can not protect fishes; the runner hole that is equipped with at half floating member middle part can be used for the rivers circulation on the one hand, avoids the positive impact of rivers, reduces every half floating member and receives the influence of rivers, and then avoids half floating member to make whole first fish reef subassembly whole to form too big floating amount, and on the other hand then can perch for juvenile fish etc. provides and avoid the space, owing to there is the fish reef as hiding and shelters the place, can make the juvenile fish significantly reduce by the early fortune that the fierce fish caught food to improve the survival rate of juvenile fish.
