Problems solved by technology

The existing artificial fish reef is an artificial reef specially designed to proliferate aquatic organisms. It is artificially set in the water area to provide a place for growth and reproduction of freshwater organisms, so as to achieve the purpose of optimizing the underwater environment, protecting and multiplying fishery resources. The existing artificial Most of the fish reefs are bottom-sinking fish reefs, that is, the fish reefs will sink to the bottom of the water after they are put into the water area. The reefs are generally made of concrete. Effects on the quality and quantity of the population of proliferating freshwater organisms

Embodiment 1

[0027] like figure 1 , figure 2As shown, the present invention provides a three-dimensional freshwater fish germplasm resource protection reef, including at least three settling tubes 1, a plurality of settling tubes 1 are arranged alternately, and any two adjacent settling tubes 1 pass through several branches. The rods 2 are connected together, and all the settling pipes 1 are connected with the support rods 2 to form a hollow reef cage 3 up and down. The outer peripheral surface of the reef cage 3 is wound with a palm rope 4, and a plurality of scallops 5 are fixedly connected to the palm rope 4; The inside of the tube 1 is hollow, and is composed of an anti-corrosion layer 101, a support layer 102, an adhesion layer 103, and a bio-affinity layer 104 from the outside to the inside. The anti-corrosion layer 101 is a photolytic plastic, and the support layer 102 It is stainless steel, the adhesive layer 103 is biodegradable bio-starch resin, the bio-affinity layer 104 is ce...

Embodiment 2

[0034] Other operations are the same as in Example 1, and the difference is that the palm rope (4) is made by mixing and weaving nylon, sisal fiber, mountain palm silk and coconut palm silk with a mass ratio of 3:5:7:13. Brown rope, soak the brown rope in the acid solution for 30 minutes, then take out the brown rope and dry it; then heat the brown rope to 55°C under vacuum, treat it with a microwave with a power of 600W for 30s, and wait for the temperature of the brown rope to naturally drop to room temperature , and then use a 600W microwave to heat the temperature of the brown rope to 50°C; spray the mineral salt solution evenly on the surface of the brown rope, and spray it continuously for 5 times. After the spraying is completed, place the palm rope at 15°C and 1.8 standard atmospheric pressure for 80 minutes; the acid solution is a perchloric acid solution with a mass fraction of 0.5%. 35 DEG C; the preparation method of the mineral salt solution is as follows: in part...

Embodiment 3

[0036] Other operations are the same as implementation 1, and the difference is that the palm rope (4) is made by mixing and weaving nylon, sisal fiber, mountain palm silk, and coconut palm silk with a mass ratio of 3:2:7:11 to form a brown rope. Soak the brown rope in the acid solution for 30 minutes, then take the brown rope out to dry; then heat the brown rope to 50°C under vacuum, treat it with a microwave with a power of 600W for 20s, and wait until the temperature of the brown rope naturally drops to room temperature. Then use a 600W microwave to heat the brown rope to 45°C; spray the mineral salt solution evenly on the surface of the brown rope for 5 consecutive sprays. Dry the moisture, and then spray next time; after the spraying is completed, place the palm rope at 10°C and 1.8 standard atmospheric pressure for 50 minutes; the acid solution is a perchloric acid solution with a mass fraction of 0.5%, and the temperature is 30°C; the preparation method of the mineral s...

Abstract

The invention provides a three-dimensional freshwater fish germplasm resource protection reef which comprises at least three sedimentation pipes, wherein the multiple sedimentation pipes are arranged at intervals, any two adjacent sedimentation pipes are connected together through a plurality of supporting rods, all the sedimentation pipes and the supporting rods are connected to form a reef cage which is hollow up and down, coir ropes are wound on the peripheral surface of the reef cage, and a plurality of scallops are fixedly connected to the coir ropes. By the adoption of the technical scheme, smooth water flowing is facilitated, the blocking effect on water flow and silt is reduced, a large number of aquatic animals and plants are promoted to be attached to the artificial reef to grow and breed, fish germplasm resources near the reef are protected, and an ecological system is restored.

Description

technical field [0001] The invention relates to the technical field of artificial reef construction, in particular to a three-dimensional freshwater fish germplasm resource protection reef. Background technique [0002] Over the decades of rapid economic development, due to the construction of a large number of water conservancy projects along the river, the living environment of freshwater organisms has been replaced by artificial river banks, coupled with overfishing, the ecological environment of nearshore waters has been damaged to varying degrees, and the amount of biological resources has continued to grow. decline. In particular, the rivers where hydropower stations are built are the main living areas of China's existing freshwater fish populations, and many biological populations are on the verge of extinction. For example, the Yangtze River, which originates from the roof of the world, is home to tens of thousands of people. These people also rely on fishing for a ...
