Description

  The present invention relates to a block for providing an environment suitable for aquaculture such as abalone, sea urchin, and seafood.

  Abalone, sea urchin, and seafood are grown and cultured by sinking abalone into a gap formed by sinking abalone reefs or introducing natural stones. There is also an artificial reef that applies abalone behavior.

In addition, no consideration was given to the removal of miscellaneous algae, lime algae, adhering organisms, etc. that worsen the habitat of abalone, sea urchins, seafood, etc., and the collection work efficiency by aquatic women and seamen in the water.

  The problem to be solved is that seaweeds such as abalone, sea urchins, seafood, etc., settled and proliferated in 2 to 3 years after breeding of algae, lime algae, attached organisms, etc. Many things disappear. Seaweeds that have been washed away from the algae ground in the surrounding sea area and caught in the lower part of the block, etc., can be displaced immediately due to the influence of tidal currents and waves, etc. difficult. No measures have been taken to prevent food damage from octopus species such as abalone, sea urchin, and seafood. A long time is spent when abalone, sea urchin, seafood, etc. are collected by Ama and Ama. The object of the present invention is to provide an apparatus capable of solving such problems of the prior art.

  In order to solve the above problems, the surface of the block main body has a shape that facilitates the collection of seafood and the habitat environment, where natural algae growth is expected, and at the same time, spores and juveniles of seaweeds, etc. It is equipped with nets, ropes, porous substrates, etc. that have grown or are likely to grow. Inside the block, seaweeds that have been washed away from the seaweed beds in the surrounding sea area are inside the block from the opening on the top of the block. It has a shelf-like part that increases the staying time when it flows into the block, and a side hole for sand deposits and the like flowing in from the top of the block to the outside of the block. When the block is installed on the sea floor, it has legs that keep it stable.

  Since the block of the present invention has a shape that favors natural collection of seaweeds on the surface of the block body and favors the collection of seafood and the habitat, seaweeds fed by abalone, sea urchins and seafood It is possible to actively supply seaweeds that serve as food, and to promote their growth dramatically.

In addition, abalone, sea urchins, seafood are provided on the surface of the block body because it has a porous substrate or the like on which the algae, sea urchins, and seafood feed on seaweed spores or juveniles. It is possible to actively supply seaweeds that serve as food for the moss and promote their growth dramatically.

  When seaweeds washed away from the algae beds in the surrounding sea area flow into the block from the opening on the upper surface of the block, they stay on the shelf and prevent food from flowing out of the block, resulting in prey compared to the natural state. The stagnation rate of seaweeds is dramatically increased, and the feed supply environment is actively brought into a favorable state.

  At the same time, by having an opening, it is possible to easily enter and leave abalone, sea urchins and seafood that live in the block, and the harvesting efficiency of abalone, shellfish, sea urchins, etc. has jumped The risk of diving damage can be greatly reduced.

  Abalone, sea urchins, seafood, etc. grow inhabit, and when lime algae and attached organisms breed on the concrete surface where they live, it becomes difficult to inhabit. In order to do this, it is indispensable to remove deposits, etc. by sea maidens and seamen in the water, but by providing a shelf-like part, it is possible to improve the efficiency of the removal work and effectively use the space, and more abalone per unit area , Sea urchins and seafood greatly increase the amount of livelihood, and at the same time, the gap between the shelf and the shelves interferes with the predatory movement of octopus and other species that feed on abalone, sea urchin, and seafood. Can be drastically improved and the yield can be increased.

Furthermore, the gap between the shelf and the shelf provided inside the block body is dark even during the day, adapting to the habit of preferring the darkness of abalone, and can provide a suitable living place for abalone and can be squeezed, This makes it possible to drastically increase the number of abalone individuals that ablate per abalone growing block. Furthermore, the large number of abalone individuals that inhabit per unit area makes it possible to dramatically increase the growth rate of juveniles compared to the natural state.

Abalone, sea urchin, seafood droppings, sand that flows in from the upper part of the block is provided with a horizontal hole to discharge out of the block, allowing the seawater in the block to always flow, The oxygen concentration related to the habitats of sea urchins, seafood, etc. can be suitably maintained, and the habitat environment of abalone, sea urchins, seafood can be kept clean, so that the yield can be increased.

  The bottom of the block body is equipped with leg parts that maintain stability when installed on the seabed, so that if the bottom of the seabed is undulating, sand, mud, etc., stability can be secured at the same time A gap is created at the bottom of the sea, and abalone, sea urchin, seafood, etc. can be added to this gap.

  In addition, seaweeds that actively grow seaweeds on the surface of the block grow into mother algae and release spores to promote the formation of a new algae field with the block as the core of the algae field construction.

  In addition, by installing blocks, plankton that feeds on the bottom of the sea food chain, such as seafood, is collected, so medium-sized fish, migratory fish, etc. that feed on it will also be collected, It also promotes fishing ground development effects.

  In addition, if algae, lime algae, and attached organisms adhere to the shelf after several years after installation, and the habitat of abalone, sea urchins, seafood, etc. deteriorates, air diving from the opening in the water A woman and a seaman using the method and the submerged method can enter the block and easily clean it using a hand scraper, etc., so that the habitat can be maintained, the effect can be continued, and the yield can be increased.

  Hereinafter, the configuration of the present invention will be described in detail based on the best mode shown in the drawings.

  FIG. 1 shows an example of an embodiment of a block to which the present invention is applied. This block 1 is formed of a hollow cube having five square walls such as concrete squares or rectangles on the periphery, and a plurality of shelf-like shapes on which concrete abalone, sea urchin, and seafood are attached. 2 with a plurality of porous substrates 3 on which an abalone feeds algae spores or juveniles that feed on or are easy to grow on the outer wall surface. 4 and a leg portion 5 for maintaining stability when installed on the seabed at the bottom.

  The block 1 is made of concrete, for example, and has its own weight that does not fall due to the influence of waves. The material is not limited to concrete, and any material such as resin or metal may be used as long as the shape can be maintained. The shape is not limited to the shape shown in FIG. Any shape that can stay in is acceptable. For example, a hexagonal column or a cylindrical shape may be used. In addition, the size is suitable for the conditions of the sea area where it is installed, and it is set to an optimum size each time according to the scale of the facility. Further, the block 1 may have a structure in which a hollow cube having a shelf-like portion 2 and a square wall on five sides is integrally formed, or a structure in which a single block 1 is formed after being separately shaped and combined. Anyway.

  Further, the shape of the outer wall surface of the block 1 is not limited to a flat surface, and may be a mountain shape, a corrugated shape, or the like as long as seaweeds naturally grow and seafood is easy to collect and inhabit.

  The shelf-like portion 2 is made of, for example, concrete, and the shape shown in FIG. 2 is preferable. In addition, the material is not limited to concrete, it does not interfere with the breeding and aquaculture of abalone, sea urchin, seafood, etc., and any material such as resin, metal, etc. may be used as long as it can maintain the shape, The shape is not limited to the shape shown in FIG. 2 and may be a mountain shape, a waveform, or the like as long as it can be provided inside the block. The clearance between the shelf and the shelf may be of any size that prevents predatory activities such as abalone, sea urchin, and seafood such as abalone, sea urchin, and seafood.

  Further, the number of the shelf-like portions is an optimum number for the block size, and the thickness thereof is not limited as long as the dimensional condition of the gap between the shelf-like portion and the shelf-like portion can be satisfied.

  The porous substrate 3 is preferably attached to the block 1 as shown in FIG. 1 with the seaweed spores and juveniles attached in advance when the block 1 is installed in the sea. As shown in Fig. 1, the abalone breeding block 1 is once installed in the sea, and then the seaweed spores and juveniles may be attached to the abalone breeding block 1 by the sea maiden or the sailor. Any method may be used as long as it can grow seaweeds that feed on abalone, sea urchins and seafood.

  In addition, since the porous substrate 3 has a characteristic that the spores of seaweeds released in nature are likely to grow, seaweeds that would serve as abalone, sea urchin, seafood, etc. grow in the surrounding sea area. If there are no seaweed spores or juveniles attached to the porous substrate 3, attach them to the block 1, install them in the sea, and confirm that the seaweeds have naturally grown and grown, then abalone, sea urchin, seafood There is no problem in the breeding culture of the species.

  Further, the material of the porous substrate 3 is preferably a porous substrate mainly made of concrete, for example, but plastics, resins, etc. may be used and can be attached to the block 1 and active seaweeds. If it can be grown, the shape is not limited to a plate shape, and there are no restrictions on the size, number, and mounting position.

  There are no restrictions on the shape, size, number, and mounting position of the horizontal holes 4; sediments such as seafood droppings and sand flowing in from the upper part of the block are washed away to the outside of the block; It is preferable not to interfere.

  The bottom of the block 1 is provided with four cubic legs 5, but it is preferable to have an optimal number that can be stabilized when the block 1 is installed on the seabed. Depending on the conditions of the seabed, the shape and size are optimal for stabilization.

  For example, in general, the block 1 is preferably installed directly on the bottom of the sea, but when gravel or quarry stone is put on the bottom of the sea, in order to prevent collapse or collapse, A part of the block 1 may be dug into a hole shape according to the shape of the block, and the block 1 may be placed therein so that a part of the block 1 is buried.

It is a perspective view which shows embodiment of the block to which this invention is applied. It is the enlarged view which showed the shelf-like part with which the inside of the block main body is equipped.
