JP4947274B2 - Growth method of epiphytic marine organisms by dendritic three-dimensional structures - Google Patents

Description

  The present invention uses marine organisms that grow on a bedrock by effectively using the underwater space by using a dendritic three-dimensional structure as shown in FIG. 5, such as reef-building coral and soft bodies. The present invention relates to a propagation method for proliferating corals, seaweeds such as firefly and yoreda, and sponges in natural waters.

  There are three features of the present invention. First of all, the underwater space can be used in three dimensions as a breeding ground for marine organisms. When growing epiphyte marine organisms using only the bedrock on the seabed, only two-dimensional planar use of the area of the bedrock is made. Since the present invention has a structure having an axial column in the vertical direction, not only the sea floor but also the underwater space can be effectively used as a breeding field.

  Secondly, the present invention can be carried out regardless of whether the bottom of the seabed is sandy (FIG. 3) or rock (FIG. 4) as shown in FIG. This means that a wider sea area can be used as a breeding ground for epiphyte marine organisms.

  Thirdly, it is possible to produce a large amount of marine life with aesthetic appreciation value. Because the organisms proliferated by this method grow while growing on any natural rock or pseudo-rock, they look good when put in the aquarium and can be immediately sold at high prices as marine organisms for viewing aquariums. This is because it has features that enable it.

Furthermore, when the reef-building coral is propagated on the sandy seabed using the present invention, there is also an advantage that it is difficult to encounter the damage of the starfish. This is because the native place of the starfish is on the bedrock where there are many holes to become a hideout, and the starfish has the property of hiding in those holes during the day and living at night to eat and coral the coral. . The smaller the starfish, the more likely it is to hide in this hole. Small individuals with a body length of about 1 to 3 cm are usually hidden in groups deep inside a narrow and deep hole that cannot be reached. For this reason, open places (spaces) such as stakes are not good, and if there is not much, there is no action to climb the stakes. Therefore, it can be said that the probability of the kingfisher climbing on the dendritic structure of the present invention, which is like a pile standing on the sandy seabed, is quite low.
In this way, the fact that the sea urchin starfish does not use the sand as a usual living place, the fact that the top of the pile which is a very open space is not good place overlaps, and this invention is used for the propagation of reef-building coral in the sand It is very useful when used.

  The present invention relates to a method for breeding marine invertebrates and plants for viewing in natural sea areas. Regarding the method of breeding marine invertebrates using natural sea areas, the breeding method mainly used for ornamental purposes is (Application No .: Patent Application 2000-273695, Applicant: Onna Village Fisheries Cooperative Inventor: Kazuya Hayashigai 2. Title of invention: Coral culture method and apparatus). In this method, one coral is propagated on one pile, and the sea area is not used efficiently. Furthermore, special equipment is required for holding rocks and pseudo-rocks, which is difficult in terms of cost. In addition, although a method of multiplying multiple corals is also shown, it is a planar method of simply creating a shelf and arranging rocks on it, which is not an efficient three-dimensional use of marine space. I want.

  Most marine organisms grown on natural rocks or artificial rocks for viewing are currently growing in land tanks. Because natural seas have waves and currents, it is necessary to firmly hold natural rocks and pseudo-rocks that settle epiphytes. However, natural rocks with different shapes and sizes are cumbersome and laborious. Pseudo-rocks can be created in a uniform shape, making it easier to work underwater. However, the method of applying for Onna Village Fishery Cooperative requires special holding tools for holding pseudo-rocks and is not practical. Above all, one pile is needed for the growth of a single coral, and it is questionable whether the effort and cost of hitting the pile will pay for the price of the growth coral. For this reason, it can be said that the natural sea area has not been propagated in a form in which epiphytic marine organisms are propagated and sold together with rocks on natural rocks or pseudo-rocks for ornamental appreciation.

  The present invention provides a method for propagating marine invertebrates and plants that grow on a bedrock using a three-dimensional structure. Most of the epiphytic marine organisms are characterized by growing on the surface of rocks. Appropriate rocks with a diameter of about 5 cm to 20 cm are suitable for the purpose of selling epiphytes for viewing. This is because ornamental organisms must be transported alive and delivered by home delivery, which can be transported quickly and reliably in Japan. For this reason, a size of about 5 cm to 20 cm is appropriate considering transportation costs and packing materials. However, if such a small rock is placed directly on the seabed, the rock is easily rolled by waves and currents, and it cannot be said that it is an environment where epiphytes can grow. So, in order to prevent rocks from rolling over due to waves and currents, a method was devised in which a pile was driven into the seabed and fixed to the pile.

  According to the present invention, it is possible to proliferate a large number of marine epiphytes in a shape that can withstand aesthetic appreciation on natural rocks and pseudo-rocks as living bodies for viewing aquariums, and sell them together with any rocks that have been grown at high cost Become.

  Many epiphytic marine organisms require light to grow. Coral companions and seaweed are the typical creatures. Therefore, the present invention was born out of the idea that the shape of land trees that require light could be used as a reference for growing epiphyte marine organisms. It is a common form for trees to have branches on the side to obtain light and have trunks to support the branches.

  In the present invention, each of a large number of epiphytic marine organisms that proliferate by using a three-dimensional structure having a plurality of side branches that play the role of a shaft column and a number of protruding branches that play the same role as a tree trunk. It is possible to give a sufficient amount of light.

  By adopting such a structure having an axial column and a plurality of side branches, in addition to light, it is easy for tides to flow on each of the growing epiphytes, and for animals, plankton and plants that serve as oxygen and food If it is, it has the characteristic that carbon dioxide, a nutrient salt, etc. are supplied easily.

A plurality of side branches extending laterally from the axial column are provided with holding fields 5 for holding rocks for causing epiphytic marine life. The holding field may be a shape in which the rock is easily fixed by simply bending the wire. If the wire is bent and used as a holding field, the wire to be fixed is covered with a transparent vinyl tube so that the rock to be fixed does not slip and is easily fixed.
Further, a rubber sheet or the like stretched between two side branches may be used. And natural rock or pseudo rock is fixed to the holding place with rubber strings or wires. FIG. 2 shows a fixed state. Of course, the corals, soft corals, or seaweeds that grow on the natural rocks or pseudo-rocks to be retained are fixed in advance with wires or underwater bonds.

  In this way, using a dendritic three-dimensional structure having a shape and a material holding field 5 in which a rock or artificial artificial rock can be fixed with a wire, rubber string, etc., an epiphytic marine organism is allowed to grow on the rock or pseudo rock. Proliferating is a feature of the present invention.

FIG. 3 shows an embodiment of the sandy seabed. A side branch 2 of a stainless steel rod is welded to a stainless steel pipe with a diameter of 3 cm and a length of 2 m, which is used as the shaft column 1. This side branch 2 uses a pair of stainless steel rods with a diameter of 6 mm and a length of 20 cm. Since there are 4 sets of side branches per round, a total of 8 stainless steel bars are required. A thin rubber plate 4 is inserted into the end of the side branch to hold the rock. The distance between the upper and lower side branches is 75 cm.
It is assumed that it can stand on its own as a concrete pouring base 6 with vertical and horizontal lengths of 50 cm and 20 cm at the base of the three-dimensional structure for propagation (Fig. 1). Two or more of these three-dimensional structures for breeding are installed at approximately 3m intervals on sand at an arbitrary location of 5m depth.
The rock 3 in which the reef-building coral is fixed in advance with a wire or an underwater bond is fixed on the holding place 5 of this three-dimensional structure with the rubber string 4. And it grows with this three-dimensional structure from half a year to one year. Ships in the order in which the reef-building coral has grown to be commercially available.

FIG. 4 shows an embodiment in the case where the bottom of the sea is rock. Pile 7 is driven into the bedrock at intervals of 3 m in advance. The pile is made of stainless steel and the diameter is 15 mm. Therefore, the length is determined by the hardness of the rock. The breeding three-dimensional structure is firmly fixed to the head of the pile with the U-bolt 8.
A rock in which a reef-building coral is fixed in advance with a wire or an underwater bond is fixed on a holding field 5 of the three-dimensional structure with a rubber string 6. And it grows with this three-dimensional structure from half a year to one year. Ships in the order in which the reef-building coral has grown to be commercially available.

  The present invention provides a method for growing ornamental marine organisms while growing them on rocks. In addition to functioning as a basic producer in coral reef waters, reef-building corals play an important role as a provider of retreats for many types of fish and invertebrates. When corals are propagated according to the present invention, since the coral plays the above two roles, the breeding field will function as an artificial reef by gathering many pairs of fish and invertebrates. Therefore, it has the potential to be used as an increased production area for useful fish for the fishery industry. The same thing happens when it is used for the growth of seaweed.

  In addition, they are grown for the purpose of selling coral and seaweed for aesthetic appreciation. Because it is beautiful when placed in an aquarium, it is naturally a beautiful scenery even during breeding in the sea area. Therefore, it can be used for sightseeing as a diving point.

  It is a perspective view of the basic type of a dendritic three-dimensional structure.   It is the perspective view which fixed the reef-building coral on the rock to the holding field   FIG. 3 is a perspective view in which a dendritic three-dimensional structure is installed on the sandy seabed to proliferate reef-building corals.   It is the perspective view which installed the three-dimensional structure of the bedrock submarine dendritic structure and proliferated the reef-building coral.
