Novel artificial fish reel

Abstract

The invention discloses a novel artificial fish reel which is applicable to the open sea area with high flowing speed. Upwelling can be produced on the incident flow surface of the fish reel to convey nutritive salt on the bottom layer upwards, the primary productivity of the local sea area is improved, and the similar ecological effect of a large fish reel can be achieved. Further, the bottom of the novel artificial fish reel can be automatically buried into a sea bed to facilitate fixation. In addition, the novel artificial fish reel is small in size, and the height is less than 3m. Therefore, as long as the artificial fish reel is reasonably arranged, the artificial fish reel cannot affect ship navigation even when the fish reel is used in the sea channel area where ships come and go frequently.

Description

technical field [0001] The invention relates to the technical field of fish reefs, in particular to a novel artificial fish reef. Background technique [0002] Since there are more and more reclamation projects, there is less and less space for marine organisms such as small bays and marine wetlands to live. Therefore, it is very important to build a large number of artificial reefs in open sea areas. [0003] In open seas, the current velocity is generally relatively large, which is not conducive to the habitat and reproduction of fish. The construction of artificial reefs can reduce the local flow velocity, form a low-velocity back vortex on the back of the reef, form a space suitable for fish habitat and reproduction, and gradually develop into a spawning ground for fish. [0004] At present, artificial reefs generally use the method of scrapping ships and sinking into the sea. Due to the huge size of such artificial reefs, they are relatively stable on the seabed. navi...

AI Technical Summary

Problems solved by technology

[0004] At present, artificial reefs generally use the method of scrapping ships and sinking into the sea. Due to the huge size of such artificial reefs, they are relatively stable on the seabed. Navigation, causing traffic safety hazards

However, small and light artificial reefs are not conducive to fixing on the seabed, especially in open seas with high velocity, and are difficult to fix due to the combined influence of waves and currents.
