Abstract

The present invention provides an artificial reef for promoting fish propagation by forming an artificial reef providing a fish habitat on the bottom of the sea, particularly by an artificial seaweed attached artificial reef with a flexible membrane member formed on the permeable concrete structure seated on the sea bottom. The present invention relates to an artificial seaweed-attached artificial reef with a wave flow control function for the purpose of creating an appropriate ecological environment in which various fish and shellfish can inhabit by controlling waves and flows.

Conventionally, artificial reefs formed of concrete blocks are mainly used. In order to create an artificial reef fishery using this, a large number of artificial reef fish piled up in multiple stages in a certain area of the appropriate area is created, which requires a lot of manufacturing and installation expenses. In addition, it is a simple structure, which does not sufficiently satisfy the various physiological and ecological requirements of fish life history, and the internal center of colonies tended to become stagnant and anaerobic.

The present invention has been devised to improve the above-mentioned closed end and fastening the flexible membrane to the concrete structure and installed on the sea bottom, such as seaweeds that live on natural reefs, and can freely control the size of artificial reefs and at the same time folded or assembly It is formed and is easy to transport, and after installation, the flow of seawater, which is a natural phenomenon, is controlled, which not only increases the downstream area of the back, but also increases the size and height of the water flow to improve the fishing environment. In addition, when properly arranged, the wave energy is attenuated to improve not only the aquatic life environment, but also the fishing environment, and it is designed for the purpose of expanding the fish farms in the rear sea area.

Description

Artificial seaweed attached artificial reef with blue and flow control

In the present invention, artificial reefs for promoting fish propagation by forming artificial reefs providing fish habitat on the bottom of the sea, in particular, by installing a transmissive triangular prism on the bottom of the sea and forming an artificial seaweed by using a flexible membrane member on the top The present invention relates to an artificial seaweed attached artificial reef with a blue / flow control function for the purpose of forming a comfortable space in which various fish can be formed by controlling the waves and flow to create an environment where fish and shellfish like.

As is well known, Korea has many seas on three sides, producing a lot of marine products. Aquatic products should be protected and fostered as important national food resources, and are important marine resources to be preserved in environmental protection.

However, coastal fisheries, which are important for spawning and nursery farms, are being reduced due to the inflow of landfills and wastewater for the construction of coastal cities and export-driven industrial complexes. There is a situation.

Therefore, the importance of resource-managed cultivation fishery is emphasized. As a basic technology of cultivation fishery, it is necessary to establish good fisheries, cultivate and release good biological resources under the long-term fishery resource management system.

Aquaculture technology has been developed as a basic technology for cultivation and fish farming. However, such aquaculture not only lowers productivity but also worsens water pollution due to self-pollution caused by the excess of environmental self-cleaning ability. It is known that such damage is causing not only fisheries' seawater but also ecosystems at the bottom due to feed and sewage discharged from many farms and caused as a social problem.

In addition, such a farm has a limited productivity by artificial, and there is a disadvantage in that it can not be a method of securing the original fish resources due to the limitation of productivity and destruction of production facilities due to natural disasters, diseases of fish, etc.

Therefore, efforts are being made to increase the natural fish stocks by increasing the protection and reproduction of fish inhabiting the offshore.

In this method, artificial reefs formed of concrete blocks are used. In other words, when the inner surface of the hollow cube is formed on each side of the concrete block with a through-hole formed on the sea floor, the fish can enter and exit the block through the through hole of the block, the block protects young fish like It will be a safe fish farm to provide a breeding ground.

In addition to these blocks, large tools discarded on land such as waste ships and automobiles are stored to form a fish house by many spaces, and the protection of natural habitat fish, as well as spawning places, stable shelters and feeding sites (feeding place) The target artificial reef is known.

The well-known concrete block artificial reefs are stacked in a large size and have the disadvantages of complicated complexity and concrete and reinforcing bars that need to be stored along with their movement to fish habitats. There is a risk of seawater contamination due to corrosion and residual harmful substances, along with the problem of transporting waste ships.

In addition, they are super-large, or stacked in multiple stages using blocks, so that the lower center is completely stagnated with seawater at the bottom, causing local destruction of natural ecosystems.

The present invention has been devised to improve the closed end to mimic the seaweeds inhabited by natural reefs composed of a concrete structure and a flexible membrane body and installed on the sea floor, the size can be freely adjusted and produced at the same time folded or assembly It is easy to transport and transport, and even after installation, the flow of seawater, which is a natural phenomenon, is controlled, which not only increases the relaxation area in the background, but also increases the size and height of the water flow, and improves the fishery environment. It has been attenuated for the purpose of improving the fishery environment as well as the aquatic habitat environment and expanding the farms in the background.
