Description

[0001] The present invention relates to a seahorse having a lower illumination,

[0001] The present invention relates to a water tank for cultivating hippocampus and fry having a lower illumination, more specifically, a light source is installed in a lower part of a water tank, a lighting filter is installed to maintain a uniform illumination on the water tank, The present invention relates to a hippocampus / aquarium-style water tank having a hanger and a lower illuminator capable of preventing hippocampal fry from drifting on the surface of the hatchable water.

For a long time, sea horses have attracted people's attention as a unique lifestyle, such as the unique shape of a fish, and the birth of a female egg, which is a hot-blooded egg. The hippocampus is a tibia fish belonging to the Syngnathidae along with seadragon, pipefish, and is known to live in 36 species worldwide. Five species are known in Korea including Hippocampus kuda , H. hiatrix , H. coronatus , H. marinikei and H. trimaculatus . It lives in seaweed and seabird communities.

The hippocampus has a tail that can fix the body to the substrate, and the head is perpendicular to the body. When you swim, you can stand up and swim, your eyes move independently and rotate, you can see your head in all directions without turning your head. The outside of the body is without scales and the female hippocampus is completely wrapped around the body with armor made of bony rings like the wheel, while the male hippocampus is not wrapped around the bottom of the hippocampus. The hard bony armor also protects the hippocampus from natural enemies.

The hippocampus lives in a monogamous lifestyle and breeds in a unique way for males to breed. At the breeding season, the female and the male mate with each other in front of the ship, and the female lays eggs in the pouch (nursery bag) on the male's abdomen. From this time, the males not only take care of the embryos and hatch them, but also raise their offspring in their belts until they grow to some degree. When a male's stomach is getting more and more, and the baby's hippocampus grows up to about 1 cm, the male sends out a hippocampus, which already has the shape of an adult.

The hippocampus has attracted a lot of attention in the world market for ornamental fish market due to its unique and beautiful appearance and slow and elegant movements. In China, it has traditionally been used as various medicines from asthma to erectile dysfunction. In Korea, the hippocampus also acts on the liver and kidneys to protect the ovaries and promote blood circulation. The erectile dysfunction caused by weakness of the kidneys, nocturnal enuresis, symptoms of atrophy of the testicles, Of mental breakdown and abdominal pain.

In particular, the annual consumption of hippocampus in the Chinese medicinal product market is estimated to reach 25 million, and the price is also used as a high-quality medicinal product that is priced at 2 million won per kilo to 10 million won. Most of the hippocampus consumed in China has been naturally harvested from natural sources such as Southeast Asia.

In 2004, however, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) designated hippocampus as an endangered species, Illegal capture is prohibited, and in Southeast Asia, fisheries bans are declared in order to preserve fishery resources of their own countries. In the natural state, hippocampus, which is easily caught by low reproductive rate and slow swimming, has become indiscriminately over - exploited as the market has grown. In fact, hippocampal populations in some Southeast Asian regions such as the Philippines have been reported to have decreased by more than 70%.

However, since CITES regulates only wild animals, cultured hippocampus produced in aquaculture facilities is excluded from the regulation and is available as a target organism for international trade. However, hippocampus is very sensitive to the environment, and it is a species with a high mortality rate which causes mass mortality easily even in small environmental changes.

Currently, only 16 countries, including China and Australia, are cultivating hippocampus. Since the first artificial breeding in Guangdong in China in 1957, studies on hippocampal artificial breeding have been conducted, but commercial scale began in Australia, New Zealand and the United States in the 1990s. In particular, since 2000, Australia has been carrying out large-scale hippocampus cultivation for big-belly seahorse ( H. abdominalis ), and nine farmers in Australia and New Zealand have established a system to ship 170,000 horses each month. Market and the Hong Kong pharmaceutical market. In China, the largest consumer of hippocampus, workshops on hippocampal aquaculture, conservation and management are being actively carried out, and they are jumping into global western sea horse wars.

The most difficult and important part of the hippocampal aquaculture is to increase the survival rate of the hippocampus and fry. Particularly, the hippocampus moves up and down by controlling the amount of air in the breeze while using the fins in vertical swimming. In this process, when the air is inhaled excessively, it floats on the surface of the water and can not go down to the floor. . In Korean Patent No. 10-1054365, the present inventors have disclosed a hatching tank for hatching fish for restraining the migration of sea horseshoe crabs and fry, but the survival rate after 20 days of giving birth was only 13.5%. Therefore, the present inventors have completed the present invention after research and efforts to raise the initial survival rate of important fishes and fry in hippocampal culturing.

Korean Patent No. 10-1054365 discloses a water tank filled with seawater so that the horseradish can be reared and a seawater filled in the tank so that the food creatures of the seahorse and the feather having the star- It is located inside, and it is made up of light emitting diodes, so that the food creatures of the sea horses gather in the central area of the seawater so that the sea horses can prevent the dead sea bubbles from being blown during feeding to improve the survival rate of the sea horses Has launched a breeding tank for horses. In Korean Patent No. 10-1247609, the light is emitted vertically to the center of the bottom surface of the water tank and is emitted in a 360-degree direction, and can be maintained upright without a separate fixing device. By using the supplied external air or water, And the circulation of the water in the water tank is assisted by using air or water discharged after cooling. Korean Patent Registration No. 10-0309253 relates to a water tank for image monitoring using fishes used for detecting water quality or more of influent water or river water in a water purification plant or a sewage treatment plant. In particular, an indirect type illumination device is provided on the rear surface of the frame body, And the shape of the panel is formed in a trapezoid so that the side and lower partition walls of the panel constituting the water tank are parallel to the incident angle of the lens, And the position of the fish in the water tank can be completely tracked by the user, thereby obtaining more precise data from the fish in the monitoring water tank. In Korean Patent No. 10-0307019, a main body 100; A culture chamber (110) provided inside the body (100) and containing a fluid and growing a culture; A driving chamber 120 provided inside the main body 100; A separation plate 150 separated from the culture chamber 110 and the driving chamber 120 and provided with a plurality of fluid guides; An illumination chamber 130 provided in the main body 100 for illuminating the cultivation chamber 110; And a cover (140) provided at an opening of the culture room (110) and having a sloped surface in a triangular shape. However, in the above-mentioned invention, a light source is installed in the lower part of the water tank of the present invention, and a lighting filter is installed so as to maintain a uniform illuminance on the bottom of the water tank so that the hippocampus is collected on the bottom of the water tank, This is different from the configuration and effect of a marine hatchery aquarium having a lower illumination that can prevent death.

Conventionally, one of the most difficult aspects of hippocampal culturing has been the high mortality of hippocampus and fry during the early stages of hippocampus production. Especially, the hippocampus of the hippocampus rises to the surface of the breeding water, and it is often washed away with power. Many methods have been sought to reduce this drifting mortality. However, there was a limit to reducing the mortality rate in the critical period within 5 to 7 days after the birth of hippocampus, when sudden death occurred. Therefore, it is an object of the present invention to provide a hippocampus and a fish tank for breeding hippopotamus to reduce hippocampus, hippopotamus-related dead fishes for mass production of hippocampus.

In order to solve the above-mentioned problems, the present invention provides a water treatment system comprising: a culture water tank having a floor and an outer wall capable of transmitting light of a predetermined area and capable of receiving water for breeding; an air injection pipe capable of supplying air to the culture water tank; A drainage pipe installed on the bottom surface of the aquaculture tank for draining the breeding water, a light source installed on the bottom surface of the aquaculture tank and capable of irradiating light under the aquaculture tank, And a lighting filter inserted between the light source and the bottom surface of the aquarium so as to scatter light of the light source unit uniformly on the bottom of the water tank.

The present invention relates to a hippocampal living organism having an illumination on the lower floor of a hippocampus aquarium and irradiating a uniform light through the illumination filter to the lower surface of the hippocampus so that the hippocampus of the hippocampus, It is possible to prevent the massive mortality of the hippocampus by allowing the fish to float on the surface of the sea, thereby greatly increasing the survival rate of the hippocampus and fry.

FIG. 3 is a perspective view and a cross-sectional view of a scatter filter of a hippocampus / aquarium-type water tank having a bottom illumination of the present invention.
FIG. 4 is a cross-sectional perspective view showing a rearing condition of a hippocampus and a fry in a hippocampal aquaculture tank having a bottom illumination according to the present invention.

The present invention relates to a water tank capable of dramatically reducing the mass mortality occurring between 5 and 7 days after birth in hippocampus and rearing, and stably breeding healthy hippocampus. Hereinafter, the present invention will be described in detail with reference to specific examples.

FIG. 1 is an exploded perspective view of a hippocampus / aquarium-style water tank having a bottom illumination according to the present invention. The hatchery fish tank according to the present invention includes a water tank 100 having a floor and an outer wall capable of transmitting light of a predetermined area and capable of receiving water for breeding, A drainage pipe 150 installed on the bottom surface 110 of the aquarium so as to drain the water from the aquarium tank 160, A light source unit 300 installed outside the bottom surface of the aquaculture tank and capable of irradiating light under the aquaculture tank; a light source unit 300 inserted between the light source unit 300 and the bottom surface of the aquarium tank, And a light filter (200) for scattering light.

The raising tanks 100 for hippocampus and fry can be used as general fish breeding tanks, and transparent or semitransparent FRP tanks may be used. The bottom 110 of the tanks may be a transparent floor or a semi-transparent It has a floor that can transmit light. The hippocampus, which was the most difficult problem in seahorse, lost its ability to descend below the aquarium while swimming in the hippocampus, It floats only, but it does not reach the food and it is dead. Most of these drifting fishes and fry have come up to the surface of the breeding water, but they have drank small bubbles, and once the bubbles were weak, it was difficult to salvage them.

H. abdominalis, which has a relatively strong swimming power since the early stage of life, can maintain its body balance, has the ability to fix the body to the substrate with its tail, H. kuda or H. reidi still had a high mortality rate, although it was relatively low.

In the conventional invention according to the present invention, the bubbles are moved from the lower side to the upper side of the water tank, from the upper side to the upper center of the water tank, from the upper center to the lower center, And a weak water current circulating back to the lower side was formed so that the hippocampus and the fry were allowed to swim at the center without staying on the side of the water tank. In addition, by arranging the lighting on the front of the water tank and using the top light shielding cover on the water tank and the light shielding cover on the upper front, guiding the zooplankton to the middle of the water tank, Respectively. In this way, it was possible to reduce the mortality rate close to 100% after birth to 20 days after giving birth.

However, the lighting on the front of the water tank did not effectively prevent the hippocampus and the fry from drifting on the rearing water, and the aeration of the hippocampus did not allow the hippocampus and fry to stay in the bottom of the aquarium.

Therefore, in the present invention, a light-permeable material is used for the bottom 110 of the raising tank, and a light source 300 for irradiating the bottom of the raising tank is provided on the bottom of the raising tank. And a difference in illuminance was generated in the lower part. This is because the animal food such as the sea horse's hare, the artemia used as the food of the fish, and the neomysis are light-sensitive, and the food is gathered with the high-intensity water tank bottom 110 as compared with the upper part of the aquarium 100, And to attract the fish to the tank bottom 110. In the conventional seaweed tank, which installed a light source in the front part, the seaweed of the hippocampus was attracted to the sea hare by using the light-shielding property of the food creature, but the drifting hippocampus still appeared and the mortality rate was relatively high. This is interpreted as the fact that the light is scattered from the side to the upper and lower sides so that there is no significant difference in the contrast between the lower and the upper illuminance of the water tank. Accordingly, in the present invention, light sources are provided below the water tank, The hippocampus of the hippocampus was allowed to stay more intensively at the bottom of the aquarium.

In addition, we observed that the part environment in the breeding water changed as the food and hippopotamus and fry were concentrated at the spot where the light source was concentrated. The light source 300 is concentrated on a part of the tank bottom 110 in order to more precisely and finely control the environmental conditions of the hippocampus of the hippocampus, which is highly sensitive to the environment of water such as water temperature and dissolved oxygen, And the uniformity was maintained throughout the entire tank bottom. To this end, a light filter (200) is inserted between the light source (300) and the water tank bottom (110) so that the light emitted from the light source can be uniformly irradiated over a wide range. At this time, the light source reflector 320 enhances the efficiency of the light source 300 by concentrating the light of the light source 300 on the upper part of the water tank. In addition, the illumination device of the water tank including the light source 300 and the illumination filter 200 is supported .

The light source 300 of the present invention can be constructed by uniformly arranging LEDs or the like on the entire lower surface of the culture water tank 100. In an embodiment of the present invention, the 40w white fluorescent lamp, the light source reflector 320 ) And the illumination filter 330 were used to softly illuminate the entire lower surface of the aquarium 100. The shape of the light source is not limited and is selected taking into consideration the shape of the tank bottom and the uniform illumination.

2 is a side cross-sectional view of a hippocampal formation water tank having a bottom illumination according to the present invention. The light source reflector 320 having the light source 300 and the illumination filter 200 disposed under the aquarium 100 is fastened to the aquarium 100 by a fastener 340 and a fastening screw 350. The light source 300 and the illumination filter 200 are fixed by the light source reflector 320 by the light source fixture 310 and the illumination filter fixture 330 installed inside the light source reflector 320, Respectively. The fastening part is made of a non-permeable material and is manufactured in such a form that it can be separated and assembled so as to support and support the illumination part and the water tank.

FIG. 3 is a perspective view and a cross-sectional view of a scattering filter of a hippocampal formation water tank having a bottom illumination according to the present invention. The light source 300 uses the illumination filter 200 to uniformly irradiate light to the bottom of the water tank 110. The illumination filter may be an opaque glass, a translucent glass, an opaque plastic, an acrylic plastic, an acrylonitrile- Styrene resin or the like. The illumination filter 200 scatters and reflects light emitted from the light source 300 to uniformly distribute the light to the bottom of the water tank. In an exemplary embodiment of the present invention, Through holes 210 having a slope of 0 to 60 degrees with respect to the surface of the water tank so that the light is dispersed through scattering and reflection for a plurality of times.

In the case of an opaque illumination filter, it is preferable that the surface directly facing the light source is made of a mirror-like reflective material. The light emitted from the light source 300 is reflected again by the light source reflector 320 and then reflected by the mirror reflection material so that the light emitted from the light source 300 is reflected by the mirror reflection material, Finally, the light is emitted. In other words, the light emitted first from the light source 300 is irradiated to the light quantity and the light quality uniform over the course of the second, the process is reflected tertiary In the optical space sealed with light filter 200 and a light source reflector 320 .

4 is a cross-sectional perspective view showing the rearing condition of hippocampus and fry in a hippocampus cultured water tank having a lower illumination according to the present invention. The hippocampus of the hippocampus is transported to the bottom of the tank by the influence of the light concentrated at the lower part of the aquarium (110), and is fed with feeding activity. The air infusion tube 160 moves downward from the center of the aquarium 100 at the upper part and generates bubbles by the bubble generator 170 located at the lower center of the aquarium, Making a water stream rotating from the top of the side to the bottom again. Also, since the breeding inlet 180 is located on the side of the breeding tank 100, it helps to maintain such a flow direction. Such a flow direction is effective for keeping the hippocampus's ear and fry on the bottom surface 110 of the breeding tank with the tail hanger 400.

The tail hanger 400 is necessary for the hatching of the hippocampus to stay on the bottom surface of the water tank, and prevents the hippocampal and fry having neutral buoyancy from being swept into the water tank by the water flow in the water tank. The tail hanger 400 is formed to be evenly dispersed on the bottom of the water tank, and a material (vinyl-coated wire or plastic net) formed with an iron core inside and covered with a plastic material is suitable. And one or more of the caulking pins 410 such as a vacuum press plate are fixedly installed so as not to move.

Comparison of the number of drifting fishes in two-week-old births in a conventional fish breeding tank for each hippocampal fish species and in a hippocampal fish tank having the bottom light according to the present invention      Fish species Conventional breeding tank The horseracing fish tank of the present invention A B A B C H. kuda 52 38 2 0 2 H. reidi 46 42 One 3 3 Sum 98 80 3 3 5 Mortality (%) 49 40 1.5 1.5 2.5

The survival rate of hippocampus cultured water tank with lower illumination according to the present invention was examined after hippocampus production. The mortality rates of H. kuda and H. reidi were randomly selected from 100 rabbits immediately after giving birth in order to see the mortality rate of the critical period corresponding to 5-7 days after birth, Three groups of A, B and C were raised for two weeks in the hippocampus aquaculture aquarium with two groups of A and B and the bottom lighting according to the present invention. During the breeding, .

As shown in Table 1, the mortality rate of the hippocampus raised in the conventional breeding tanks was 44.5% on average, and the mortality rate of the hippocampus raised in the hippocampal breeding tanks according to the present invention was 1.83% And the survival rate of hippocampus and fry were significantly increased in the critical period immediately after the birth of the hippocampus and with a rapid mortality rate.

In order to prevent the hippopotamus from drifting and becoming dead, a horizontal drain pipe (130) for quickly removing the floating food on the water surface was installed. The water which is not fed in the water by the water formed in the water of the breeding water is raised on the water of the breeding water and raised along with the foreign matter floating on the water of the breeding water. And drained together with the breeding water through the formed horizontal drain pipe (130).

The drainage pipe (130) is formed parallel to the breeding water surface, and a drainage network (140) is formed on the surface that meets the direction of flow of the breeding water, and breeding water is drained through the through hole. In addition, the opposite surface of the through hole was formed as a horizontal drain pipe having a wall, so that the water containing floating matters was drained without being collected. Therefore, the floating water that is floating on the rearing water is drained through the general water recharge process. The amount of water in the breeding water is determined by the amount of water supplied to the breeding house, and the amount of water in the water tank 100 is determined according to the position where the water drainage pipe 130 is formed. Thus, the floating food of the rearing water can be quickly removed, and the seahorse can be prevented from drifting to the rearing water after the rearing of the seagrass.

According to the present invention, the water-holding tank of the hippocampus was able to significantly increase the survival rate by suppressing the development of the sea horse's hippocampus and drifting fry at the early stage of the frying. However, for the mass production of hippocampus, it is necessary to establish breeding conditions that can manage the subsequent mortality rate continuously.

The present invention relates to a hippocampus-positive water tank for reducing the high mortality of hippopotamus and hippopotamus, wherein a light is installed on the bottom of the tank and uniform light is irradiated on the lower surface of the hippocampus, , And it is possible to prevent the massive mortality caused by the sea horse's tail and frying while drifting over the surface of the sea, thereby providing a footprint of the hippocampus, which is rapidly increasing in demand, There is a potential for industrial use.
