Description

[Detailed description of the invention] The invention relates to a large artificial fish reef that can be loaded with stone and can be salvaged and moved as necessary.

To explain the embodiment of the divisional plan using diagrams, 1 is a square bar with a through hole 2 pierced in the longitudinal direction, which is stacked in multiple stages with the orientation changed at right angles for each stage, and both sides are aligned in short lengths. Square bars a, a... are inserted between each stage of square bars a, a..., and the intervals between the square bars a, b... in the longitudinal direction are wide at the top and narrow towards the bottom, and are arranged and connected in a V-shape. It is characterized by its structure.

C and C are the square bars at the bottom, with wide gaps on both sides for stable holding.

In addition, several hanging fittings 3, 3, 3, 3 shall be fixed to the top corner bar, and during use, stones and gravel shall be thrown into the V-shaped gap hole in the center and piled up randomly. , there is a gap B on both sides of the bottom,
C is formed.

The demand for larger artificial fish reefs has increased year by year, but in the past, there was no concept of simply sinking large fish reefs and pulling them up again after they were introduced, so researchers and producers have been trying to monitor the habitat conditions of fish and shellfish after they have been introduced. , it was extremely uncertain as it could only be confirmed through the eyes of a professional diaper.

In addition, after large fish reefs are sunk to the seabed, stones are added to stabilize them and to create nursery areas for young shellfish using the complex gaps between the stones. The weight of the stone made it impossible to lift the bottom plate.

In this application, stones that serve as a nursery place for young shellfish can be placed and held in a V-shaped gap hole formed by a V-shaped step, and by adjusting the amount of stones thrown in, they can be lifted up and observed directly on the sea surface. Because of this, it is possible to extract a large number of fish reefs that have been introduced at the same time in each area and manage them by lifting them, and in some cases, they can be relocated. In addition to being able to throw bait as bait, the gaps B and C can stop feed such as kelp and seaweed flowing on the seabed and allow it to stay there.

As described above, according to the present application, the ■-shaped gap hole serves as a nursery ground for young abalone shells by holding stones thrown in, and the ■-shaped gap reduces the amount of stones, making it easy to salvage and relocate. It is easy to manage, the gaps on both sides stop the flow of feed flowing on the seabed, it is lightweight and economical overall, and problems that were previously unknown can be solved by lifting it to the sea during aquaculture for research. It is something that has the effect of obtaining.

Claims (1)

[Scope of utility model registration request] Square bars in the longitudinal direction that are sandwiched between each tier on both sides of an artificial fish reef, in which square bars made of concrete, etc., have through-holes in the longitudinal direction are stacked in multiple tiers, changing the orientation at right angles for each tier. This is a large artificial fish reef made by arranging and connecting the two layers in a V-shape so that the spacing becomes narrower toward the bottom.
