Suspension-type net cage and fish reef coupling system

Abstract

The invention discloses a suspension-type net cage and fish reef coupling system. The system comprises fish reef net cages, connecting ropes, lifting ropes, lifting devices, net box bodies, upper fixing rings, airbags, net covers, openings, fixing ropes, fish reef bodies, transverse through holes, longitudinal through holes, lower fixing rings, bottom plates and the like. According to the fish reef net cages arranged in the system, net cages and fish reefs can be combined, so that the system has not only the functions of the net cages but also the functions of the fish reefs, and the breedingeffect is improved. The lifting devices arranged in the system can make the combination of the fish reefs and the net cages stay at any height for suspension during lifting by loosening the lifting ropes so that different water layers can be fully utilized for breeding. In the system, a plurality of channels are formed in the fish reef bodies, and correspondingly not only can fry be put into the fish reef bodies for breeding, but also fishes can be attracted to perch in order to proliferate fishery resources. In the system, the fish reef net cages in the system can be arrayed and combined in different modes and positioned at different water layers, so that the demands of breeding under different conditions are met.

Description

technical field [0001] The invention relates to the field of marine fishery facilities, in particular to a suspension type net cage and fish reef coupling system. Background technique [0002] The net cages in the ocean are used for farming, but the net cages face the damage of wind waves and currents, so placing the net cages below the sea surface can reduce the threat of wind waves; there is another problem with the net cages, because the remaining bait and fish around the net cage culture Excreta and other wastes are likely to cause water pollution, while artificial reefs are facilities for the proliferation of fishery resources and can be designed into a variety of structures. Its proliferation principle is to use the principle that fish like to live around complex structures, attracting School of fish inhabits in its internal and external surrounding environment, but cannot carry out fish cultivation, so the combination of net cage and fish reef in the present invention...
