Embodiment Construction

[0014] Below by embodiment, technical solution of the present invention is described further in conjunction with accompanying drawing:

[0015] see figure 1 , an upwelling artificial reef provided by the embodiment of the present invention is composed of a reef upper body 1, a fish reef lower body 2, a support column 3 and a base 4, and the fish reef upper body 1 has sides of The inner hollow convex structure of the concave curved surface, each surface of the upper body 1 of the fish reef is provided with a through hole 11, and the lower body of the fish reef 2 is an inner hollow convex platform structure with each side being a concave curved surface, so The lower body 2 of the fish reef is fixed on the base 4, the upper surface of the lower body 2 of the fish reef is provided with a through hole 21, and the through hole 11 on the bottom surface of the upper body 1 of the fish reef is opposite to the through hole 21 on the lower body 2 of the fish reef. The support column 3 i...

Abstract

The invention relates to an upwelling artificial fish reef. The upwelling artificial fish reef includes an upper fish reef body, a lower fish reef body, support columns and a base. The upwelling artificial fish reef can provide a necessary safe habitat for gathering, feeding, reproduction, growth and enemy avoiding of aquatic organisms such as fishes, can generate upward flow, can change distribution of an internal flow field in the sea area, can drive exchange between bottom nutriment salt materials and upper water, can provide nutriments for reproduction and growth of plankton in the upper water, can establish a good marine organism habitat environment, can enhance the reproduction ability of the plankton, can form an excellent bait field, can attract migration fish to gather and stop, and can achieve a better fish gathering effect. The Upwelling artificial fish reef can effectively prevent blocking of the fish reef in use; sea current flows through the lower fish reef body to generate the upward flow to drive sea water in a cavity of the upper fish reef body to flow so as to remove sand in the cavity of the upper fish reef body, the survival reproduction space of aquatic organism such as fishes can be ensured, and the primary productivity of a near sea area can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of fish reefs, in particular to an upwelling artificial fish reef. Background technique [0002] Since the 1980s, due to overfishing and environmental pollution, especially the high-intensity operation of lethal fishing gear such as bottom trawling, the ecological environment of my country's offshore fisheries has deteriorated and fishery resources have declined. In view of the above problems, it is imperative to take measures to improve the marine environment and resources. Among them, putting artificial reefs in the offshore to improve the marine ecological environment has achieved good results. Putting artificial reefs is very important for restoring and protecting offshore fishery resources, improving The coastal ecological environment has played a very important role. The development of artificial reefs has great strategic and far-reaching historical significance for restoring and improving the marine ...
