Concrete block for habitation of damselfish and benthos

The present invention relates to a concrete block for maturity spawning and marine benthic habitats, and more particularly, to a spawning place that is stable to marine aquatic organisms such as fish, sea cucumbers, and octopus, as well as the spawning characteristics of zodiac. It relates to concrete blocks for spawning dorsal spawning and marine benthic habitats that can simultaneously provide habitat for habitat.

'Cromis notatus', named 'Jari' for living all in one's life, is known as a 'slip-fish' in marine life because it has a settleability that does not move far from its place of birth. .

They especially like warm water and are distributed in subtropical and temperate seas of the Northwest Pacific. They are found on Jeju Island in Korea and are famous for their specialties. Zodiacs flock around corals and reefs and feed on zooplankton.

Zodiac has a side-flat oval shape that grows to about 18 cm. The body color is grayish brown on the back and blue silver on the belly. There are dark blackish blue spots on the pectoral fin and white spots on the lower back of dorsal fin, which disappear as soon as they come out of the water.

The spawning season is usually between May and August, when males attract several females to spawning grounds, where the males have a paternity that protects the eggs until they hatch. The female lays about 20,000 eggs at a time, and the eggs hatch after about 4 days.

Zaridome is a subtropical fish that likes warm water and its habitat does not move, so it was only found in the coast of Jeju Island in Korea in the past, but has recently been found in the southern coast of Busan and Ulleungdo.

Preferred places for spawning as described above are as follows (see Figures 4 to 6).

-Concave space of a pile of stones.

Open space (open opposite side must be blocked)

-There should be a lot of stones such as gravel on the sea floor.

-Male should be able to easily defend the enemy.

-Depth of spawning a lot around 10 m.

-There should be plenty of stones on the floor that can be lifted by an adult man (scattering the spaces between the stones).

-After spawning in the space between the stones in the bottom, the males supply oxygen to the fins, so scattering mainly on the stone's side wall.

The spawning place in the natural state of zodiac prefers the same place due to the spawning nature.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The spawning property of zodiac has a number of piles of stones at the bottom and scatters in the concave gaps of the piles. When spawning, milky white traces are easily found.

And the scattering feature of zodiac is group life, spawning in certain places, spawning in certain structural spaces. The size of the space is observed in the range of approximately 80 mm to 160 mm in diameter, and since the eggs are to be supplied to the eggs scattered using the fins, scattering around the side wall for easy oxygen supply. Preferred depths for spawning range from 5 m to 10 m and spawning beyond 15 m is rare. Most eggs are observed to be less affected by algae and rarely spawn in too many algae.

Concrete block for the habitat of the dome scattering and marine benthic creatures of the present invention produced by using the scattering characteristics of the dome, as shown in Figures 1 to 3, the cylindrical body 10, a plurality of circular format (11), hemispherical format portion 12, and the ring (13).

The main body 10 has a cylindrical shape with a wide bottom and a narrow top, which can be stably installed on the sea floor, and minimizes the resistance of water so that the current flows smoothly in any direction, and provides a habitat environment for zodiac. It is a structure that can be formed as much as possible the circular format 11, the body 10 may be formed in a dome-shaped or elliptical cylindrical shape.

The main body 10 is made of a concrete material to manufacture a special concrete mixed with a mixture of silica fume in the range of 3 to 10% by weight relative to the weight of cement as a mixed material in order to suppress the elution of strong alkali (pH) inside the concrete To prevent contamination,

The circular formatter 11 is configured to provide scattering and habitat space of the dome while a plurality of concave circular grooves having a predetermined depth are formed along the side circumference of the main body 10.

The circular format section 11 is formed as a concave circular groove having a certain depth, the entrance is open and the end is in a closed state, the zodiac is only one male zodiac guarding the eggs laid after the female spawns. If the inlet and outlet of the circular format section 11 is open and both sides are open, the seat dome cannot protect both the inlet and the outlet. Therefore, the circular format section 11 has only the entrance and the end is formed in a closed state. When females spawn eggs around the concave entrance of the circular template 11, the male can keep the entrance of the circular template 11 until the male hatches after fertilization, and the entrance and exit of zodiac at the entrance side. This freedom allows them to easily evacuate and inhabit internal enemies in the event of external enemies, typhoons or strong tides.

On the other hand, zodiac has a maximum body length of 13cm and generally has a size of 10cm, and the circular form is due to the nature of zodiac that spawns eggs, protects them, and scatters them around the side wall to supply oxygen to eggs that are scattered using fins. Since the diameter of the part 11 should not be too small or too large, it is preferable that the inlet diameter of the circular format part 11 is 8-16 cm.

In addition, since the dome is scattered on the concave inlet side of the circular formatter 11 due to the scattering characteristics, the depth of the circular formatter 11 does not need to be too deep, but if the depth of the circular formatter is too thin, defending against external enemies. Since the depth of the circular format portion 11 is preferably 15 ~ 20cm, the circular format portion 11 may be formed in an oval shape, the narrower the diameter toward the end from the inlet side to form Allow them to provide hiding space for Zaradom.

The hemispherical template 12 is formed in a hemispherical groove on the bottom surface of the bottom of the body 10 to provide a place where the marine benthic species such as sea cucumbers and octopus prefer to inhabit the underwater bottom at the same time It is possible to function as a stable spawning and habitat for marine benthic creatures, one or a plurality of inlet 120 is formed on the side of the hemispherical habitat (12) to freely enter and exit the marine benthic creatures.

The hemispherical formatting part 12 is preferably formed in a hemispherical shape with a lower diameter of at least 20 cm or more for stable spawning and habitat of marine benthic organisms such as octopus, and easy entry and exit of marine benthic organisms and external foreign objects or bulky foreign bodies. The inlet 120 has a circular or oval shape in order to prevent the inflow into the interior, and has a maximum diameter of not more than 10 cm, thus creating a favorable habitat environment for marine benthic species such as sea cucumbers and octopuses that prefer to inhabit the bottom. Enable to provide

The ring 13 is made of steel wire or rope and is formed in the center of the upper surface of the main body 10 so that the concrete block can be conveniently transported and installed in the water by using lifting equipment.

On the other hand, the upper surface of the main body 10 is formed with a plurality of attachment grooves 14 formed in a square or polygonal shape to provide the initial nesting function of the microalgae and micro flora and fauna, each of the plurality of attachment grooves 14 Dimples 140 are formed.

In general, where marine microalgae first attach and grow is not a smooth surface, and the preferred location is the edge boundary, and there are various reasons for preferring the edge boundary, but first, the corner can be protected from the feeding of fish. Due to the morphological structure, the attachment grooves 14 formed on the upper surface of the main body 10 according to the characteristics of the marine microalgae and the micro-animals are formed in a square or polygonal shape to form a plurality of upper surface of the main body. A plurality of dimples 140 were formed in each of the attachment grooves 14 so that the edges could be formed, and the specific surface area was enlarged to more effectively attach the marine microalgae and the microflora, and the dimples 140 were In order to increase the adhesion effect of marine microalgae and microflora, it is preferable to form a diameter of 5 ~ 20mm.
