Positioned-point piling type artificial fish reef releasing method and artificial fish reef obtained by method

Abstract

The invention discloses a positioned-point piling type artificial fish reef releasing method. The method includes: using reinforced steel bars to connect 4-8 concrete components to form a single fish reef, going to the sea when the whether is good and ocean current is gentle in flow rate after multiple fish reefs are prepared, using a GPS for positioning, dropping the anchor of a ship at the positioned point, using a crane to release the fish reefs into the water on the leeward side and along the flowing direction of the ocean current, releasing 50-80 fish reefs at each positioning point to allow the fish reefs to form a rectangular fish reef pile whose length direction is vertical to the flowing direction of the ocean current, releasing multiple fish reef piles to allow the same to be distributed in a grid shape, wherein the distance between every two adjacent fish reef pile is 300-500m.

Description

technical field [0001] The invention relates to a method for putting in artificial fish reefs, in particular to a method for putting in artificial fish reefs of a fixed-point accumulation type. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. At present, the construction of artificial reefs has been widely carried out at home and abroad, and the restoration of offshore marine habitats and fisheries has been carried out, and good results have been achieved. When traditional fish reefs are released, only one fish reef is usually released at one delivery point. In this way, there are fewer gaps and caves in the fish reef to avoid, and the changes ...

AI Technical Summary

Problems solved by technology

When traditional fish reefs are released, only one fish reef is usually released at one delivery point. In this way, there are fewer gaps and caves in the fish reef to avoid, and the changes in the surrounding water flow are relatively small, which is not conducive to fish habitat, and it is also not conducive to the emergence of upwelling
