Abstract

A multifunctional artificial fish reef is composed of a fish reef body, a buoy, a cable, a wire and a gas-guide tube, wherein the cable, the wire and the gas-guide tube are connected with the fish reef body and the buoy.The multifunctional artificial fish reef not only can provide a reproduction and forage place for fishes, but also can introduce air above the sea surface into the seabed by utilizing wave energy, water and gas exchange in the fish reef sea area is promoted, needed oxygen is provided for shellfishes and sea cucumbers and the like, and the blocking in the fish reef using process can be effectively avoided.Ocean current drives impellers to rotate, the distribution of a flow field in the sea area can be changed, bottom layer nutrient substances are driven to perform exchange with the upper layer water body, nutrient is provided for reproduction and growth of planktons and the like in the upper layer water body, a good marine organism habitat is created, and primary productivity in the surrounding water area is greatly improved.A solar panel on the buoy can convert solar energy into electric energy to supply power to LEDs on the reef body, and thus the goal of attracting phototactic fishes is achieved.Staggered separating tables in the reef body increase the adhering area of the artificial fish reef, and the number of organisms in the sea area is increased.

Description

technical field

[0001] The invention relates to an artificial fish reef, in particular to a multifunctional artificial fish reef. Background technique

[0002] In recent years, although the development of my country's fishery has advanced by leaps and bounds, traditional marine fisheries are still in the extensive stage, with small scale and relatively low output value. The main manifestations are: excessive fishing intensity in the ocean, continuous decline of fishery resources, and continuous decline of fishery production; degradation and loss of marine habitats, marine fisheries, especially bottom trawling fisheries, structural changes in the habitats of marine low-dwelling organisms ; The populations and species of marine organisms have decreased, and the resource structure has deteriorated. For a long time, under the pressure of continuous high-intensity fishing in my country, the marine environment and fishery resources have been severely damaged. In view of the above p...
