Embodiment Construction

[0023] The present invention will be further explained and described below through specific embodiments in conjunction with the accompanying drawings.

[0024] The present embodiment is a composite artificial fish reef, such as figure 1 As shown, the fish reef is composed of a concrete square frame 1, a plurality of tire-shaped concrete members 2 and a plurality of bait culture substrates 3, which provide a space for young fish to avoid predators while generating a strong flow field effect, and Promote the proliferation of bait organisms, thereby improving the survival rate of juvenile fish.

[0025] Specifically, such as figure 2 There are circular openings 5 ​​on the walls of the concrete square frame reef 1 upstream and downstream surfaces. In this embodiment, the two wall surfaces are selected to have four circular openings 5 ​​respectively. The diameter of the circular holes is 40cm. Square frame 1 side It is 200cm long and has a wall thickness of 10cm.

Abstract

The invention relates to a composite type artificial fish reef which comprises a square frame reef, tire-shaped concrete components and a bait culture medium. The square frame reef is arranged in a hollow mode, the incident flow face and the reverse flow face of the square frame reef are symmetrically provided with circular open holes respectively, the tire-shaped concrete components are symmetrically arranged at the upper portion of the square frame reef, meanwhile, the multiple tire-shaped components and the bait culture medium are symmetrically arranged on the two side wall faces of the square frame reef, and shells are arranged in the bait culture medium. Obviously, while the composite type artificial fish reef solves the problem of tire reef pollution, the advantages of the tire reef are reserved, the formed flow field effect is good, larger upward flow and back eddy flow are formed, the reef influence range is enlarged, the better survival environment is provided for advanced fries and juvenile fish, the juvenile fish survival rate can be greatly increased, fishery culture and proliferation and aquatic organism diversity protection are facilitated, and the better application prospect is achieved.

Description

technical field [0001] The invention relates to a composite artificial fish reef, which belongs to the field of fishery engineering facilities. Background technique [0002] Artificial fish reefs are used to improve the environment of the sea area, provide a good habitat for marine organisms, and achieve the purpose of multiplying and maintaining fishery resources. The artificial reefs launched in the past have a single function and cannot meet various needs well. In different periods and under different conditions, artificial reefs have different requirements for the role of artificial reefs. Therefore, the materials and structures of artificial reefs in different periods are different. [0003] Today's artificial fish reefs are mostly composite artificial fish reefs to meet the different interests and needs of the investors. There are various reef building materials for artificial reefs. Waste tire reefs can produce good ecological effects in a short period of time, and ...
