Abstract

PROBLEM TO BE SOLVED: To provide an artificial fish-breeding reef which can simply be manufactured from familiar materials and has regular appearance and form. SOLUTION: This hand-cooked artificial fish-breeding reef is manufactured by inserting concrete pieces, rocks (3) and a material to make gaps into spaces between several pipes (1) having opening parts (2) cut out in middle parts so as to form voids around the opening parts (2) as a center, arranging them and covering the arranged materials as a core with cement or a resin material (5).

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a private group,
Or, it relates to artificial reefs that are created and installed by fishery cooperatives. [0002] In order to collect fish and shellfish such as fish and shrimp, it has long been practiced to throw rocks into the sea or sink abandoned ships. At present, there are two major types of public works: the Tsukiiso Project, which targets marine marine products such as lobster and abalone, and the artificial reef, which mainly targets fish. Fish reefs that are large and sunk and have a deep depth are being developed steadily, as compared with natural reefs in nature, but they can be easily handmade using materials everywhere and can be installed underwater by themselves. There are no small reefs that can be easily handled by ourselves. Some attempts have been made to privately lay sea shores and artificial reefs for fishing and diving as recreation, but since there is no artificial reef suitable for private production,
Household sinks, bicycles, sewing machines and other waste are put into the sea as artificial reefs. This means that you are dumping garbage into the sea, and fish are gathered in the dumped garbage. [0003] In order to protect the marine environment, the fishermen, sports divers, and recreational fishermen (fishermen) must work together in cooperation with each other, regardless of the purpose. . If diving clubs and diving resorts can create and sink artificial reefs with the consciousness of creating their own seas, great effects can be expected. However, since there is no type of small fish reef, it is difficult for fisheries officials and regulatory agencies to approve the subsidence of fish reefs. We need artificial reefs that are easy to build, can be laid down by ourselves, and are well-shaped, as recognized by regulatory agencies. [0004] A pipe made of any material,
Prepare concrete pieces to be discarded, ubiquitous rocks, overlying cement or resin material. Several pipes with openings cut out in the middle are placed at appropriate intervals by sandwiching concrete pieces, rocks, etc. of the demolished building, so that a cavity is created in which organisms can enter. Bundling, pouring cement, synthetic resin, etc. over the bundle and hardening it so that it does not move, it is usually seen on the sea floor as an appearance, and it looks like a rock where fish live, and it looks like a seabed Sinking in FIG. 1 is a schematic diagram showing an embodiment of the present invention. As shown in FIG. 1, the thickness of the pipe (1) may be irregular. Because the size of fish and shrimp that can be populated also varies, it may be better to change the pipe thickness. An opening (2) is formed by cutting out the middle of the pipe, and concrete pieces and rocks (3) to be sandwiched are arranged so that a cavity is formed around the pipe opening. The pipe may be made of any material that does not contain environmental pollutants, such as a steel pipe, a scuba cylinder to be discarded whose head or bottom is cut off, or a synthetic resin pipe. At least two of the pipes used should have their heads protruding on both sides and be completely penetrated, and the two penetrating pipes should cross. It is strongly tied up with the line (wire) and put together (4). Apply cement or resin to cover the pipe (1) and concrete pieces and rocks (2) and harden it (5) Make it look like a fish-inhabited rock, commonly found on the sea floor . As shown in FIG. 2, a rope (6) is used to suspend a fish reef block by passing a thick rope through a crossed pipe. [0006] The reef to be manufactured is made of pipes of any material,
Concrete pieces to be discarded, rocks that are everywhere, cement or resin that fills the space are materials,
The size is not specified separately. The type and size of the target seafood differs depending on the area. If the main purpose is shrimp, bundle many thin pipes. If fish are the main purpose, thicken the pipes. The shape can be variously changed depending on the surrounding environment. Based on the ecology of the creatures they dive and observe, each fish reef is characterized by its ability to create its own desired shape. As shown in FIG. 3, the fish reef block is installed by attaching a large floating bag (7) for injecting air to a rope (6) passing through a pipe penetrating the fish reef, and moving the fish by towing it. At the intended location, evacuate the bag and set it down. This method is commonly used for moving heavy objects in water, salvage work, and the like. Since it is considered that the total weight of a general diver can safely perform such an installation method up to about 2 tons, the weight of the reef is also limited to about 2 tons. Water depth 1
If it is installed at a distance of 5 m or more, it is less affected by waves and is stable. Even if it is swept away, it can be easily returned to its original position by diving work, and if the effect does not appear at the place where it was installed, it is easy to move the position. [0008] Since it is considered that the effect of a single fish reef is small, a plurality of fish reefs may be installed in close contact with each other or more than ten fish reefs may be installed (9). [Effects of the Embodiment] Okinawa Prefecture is assumed as an area where the fish reef of the present invention can be effectively used. In Okinawa, patch reefs where appropriate rocks are scattered in the sandy land are homes for subtropical fish and shellfish, but many divers have come and consumed them, and coral species on the surface also died. In many cases, they have lost their beauty and fish have been reduced. Such a small reef can be revived by using a material to which the reef-building coral easily adheres to the surface of the fish reef block of the present invention. (8)
Also, the installation of the fish reef block of this patent will be an experiment to restore coral reefs. [0010] The size of the pipe, the space created inside, etc. can be made to resemble the shape of the rock that collects the most fish in the area, so that a highly effective fish reef can be created. It can be used as a resource for studying the ecology of living organisms, because it can make various efforts to collect fish. The present invention has the effect of collecting fish and shrimp,
You can hold social gatherings during the process of making your own reef, or you can raise awareness of environmental conservation and spread the idea of cherishing the sea. By continuing the nature observation with the fish reef as a fixed point, the artificial reef can experience the effect of collecting fish by itself, so if a general sports diver group manufactures the fish reef of the present invention, as a coastal fishery promotion measure It is also possible to deepen the understanding of the full-fledged reef development project that is underway.
