Preying-facilitated artificial reef

Abstract

The invention discloses a preying-facilitated artificial reef which aims for settling defects of single functions, inconvenient preying of fish swarms at a reef position and easy blockage after an existing artificial reef comes into service. The preying-facilitated artificial reef comprises an alga culturing substrate and a reef substrate. A pull rope and a mesh bag are connected between the alga culturing substrate and the reef substrate. The alga culturing substrate is connected with impact balls which are used for impacting with the reef substrate. The reef substrate is provided with high-pressure gas which is used for flushing a fish sheltering chamber. The impact balls trigger a rebound mechanism. The rebound mechanism cuts a gas cover to open. The high-pressure is discharged and flushes the fish sheltering chamber, thereby preventing blockage of the fish sheltering chamber. The artificial reef can provide a place for inhibition, breeding, baiting and sheltering for fish swarms and furthermore can be used for culturing the alga, thereby realizing convenient preying of the fish swarms. After the artificial reed comes into service, blockage of the fish sheltering chamber in the reef substrate does not easily occur, thereby facilitating aggregation of the fish swarms.

Description

technical field [0001] The present invention relates to an artificial fish reef, more particularly, it relates to an artificial fish reef which is convenient for hunting. Background technique [0002] Artificial reefs can improve the ecological environment of the sea area, create a good environment for marine life to inhabit, and provide places for fish reproduction, growth, feeding and sheltering. Therefore, the placement of artificial reefs plays an important role in the development of marine fisheries. However, many reefs in use now have a single structure and function, and it is inconvenient for fish to catch food at the location of the reef, and the reef is prone to blockage after being put into use, so that the reef cannot play its role well. SUMMARY OF THE INVENTION [0003] The invention overcomes the shortcomings of the existing artificial fish reef with single structure and function, inconvenient fish feeding at the fish reef position, and easy blockage phenomeno...

Problems solved by technology

[0003] The present invention overcomes the disadvantages of the existing artificial fish reef with single structure and function, the inconvenience of fish shoals predating on the fish reef, and the clogging phenomenon that occurs easily after the fish reef is put into use, and provides an artificial fish reef that is convenient for predation. Its structure It has various functions. It not only has the function of fish reef, but also can cultivate seaweed. It is convenient for fish to prey on the fish reef, and seaweed can also be used as bait for fish. play its role well
