Upwelling artificial fish reef

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 ...

AI Technical Summary

Problems solved by technology

[0003] Although there are many kinds of existing artificial reefs, they are mainly aimed at providing places for fishes to reproduce, grow, bait, and shelter enemies. Thus, the emergence of thermoclines and haloclines in the sea area slows down the vertical exchange of water bodies and forms an anoxic layer on the seabed, which easily leads to the death of sea cucumbers and other aquatic organisms
