Description

The present invention is directed to a land-based tuna farming systems, particularly to land-based tuna farming systems with optimal water on land tuna farming.

  All patents, patent applications, patent gazettes, scientific papers, etc. cited or identified in this application are hereby incorporated by reference for the purpose of more fully explaining the current state of the art regarding the present invention. Include a description of

For Japan, fishery resources occupy a large proportion of daily life in their foodstuffs, and in particular, tuna and marlin are used and consumed as fresh fish much more than other countries. is there.

  However, the natural tuna that is caught is internationally managed for its resource maintenance and effective use, so that it is not used or consumed sufficiently in the country, and its supply The lack of volume resulted in high prices in the market.

In particular, when the farming of tuna, the important of sea water and feed state or sufficient migration can place such as the levator Gerare for oxygen intake, moreover, must be farmed environment is also taken into account from that originally nervous .

  In addition, damage such as natural disasters that occur during aquaculture must be anticipated in advance, and the aquaculture ginger naturally has a radius of at least 50 m in order to cultivate giant fish from 150 cm in length to a maximum of 300 cm. In addition to the above-mentioned adverse conditions at the time of aquaculture, in addition to the existing fishing grounds, the desired installation location cannot be obtained sufficiently.

  Most conventional aquaculture is small-scale aquaculture using the sea surface. In this case, the company cannot use the sea surface directly because it requires a zone fishery right. Among them, terrestrial aquaculture such as flounder, prawn, etc. can be carried out independently by a business entity because it does not require fishing rights. In addition, it is easy to manage the traceability of foods such as safety and security, which is currently a problem as a merit in land farming. In addition, a HACCP hygiene management system that is difficult to achieve by sea surface aquaculture is possible. On the other hand, water intake is a problem in land farming. In general, it is necessary to occupy part of the coast and extend water intake facilities to the sea area.

  On the other hand, fish caught in the sea area have received more trust in safety than conventional farmed fish. However, in recent years, it has been clarified that environmental hormones, heavy metals, and the like exist in the sea area and are biologically concentrated. Rather, fish farmed with a decent management system are becoming safer. Bioaccumulation is highly accumulated in higher ecosystems in ecosystems, and cadmium and mercury are detected from living organisms in organisms such as tuna. Furthermore, there are various problems such as the 200 nautical miles problem and the Washington Convention in the current state of highly migratory fish such as tuna, making it difficult to determine how long the current fishery can continue.

Therefore, the applicants have conducted intensive research on the above-mentioned problems, and as shown in Patent Document 1 and Patent Document 2, water is supplied from one side of the water tank so as to have a predetermined flow rate. However, in a state where a series of water flow paths are formed in the water tank drained from the other side of the water tank, fish is introduced from one side of the water tank, and the inside of the series of water flow paths is adjusted to the swimming speed of the fish. By adjusting the flow rate of the water in the aquarium and suppressing the amount of fish swimming in the aquarium, the fish is cultivated to give unnecessary stress to the fish in artificial tuna culture. It proposes a fish culture apparatus and method that can be cultivated to excellent quality without any problems and provide a stable market.

  Further, in Patent Document 2, “a water tank for storing fish inside, a tank provided above the water tank, and a supply for introducing water from which the fish connected to one side of the water tank can live from the tank” A fish culture apparatus having means, connecting means for connecting to the other side of the aquarium and discharging the water in the aquarium, and a fish input section and a fish extraction section provided at appropriate positions in the tank, The water tank is formed in a hollow cylindrical shape that extends from the one side portion to the other side portion, and is provided so as to be spiral from the one side portion to the other side portion. A fish lowering tank having a cylindrical lower water storage tank at a lower portion of the water tank, wherein the inside is filled with the supply means and the connection means so that the water has a predetermined flow rate. The lower water storage tank side An opening is provided in the connection means, and the fish is trapped in the connection means by flowing on the horizontal bottom surface in the lower water storage tank at the flow rate by the weight of the water due to the weight of the water. We are developing aquaculture equipment.

  However, in both Patent Document 1 and Patent Document 2, securing seawater for aquaculture at a constant temperature and cleanness becomes a serious issue. In general, surface seawater has the advantage that warm seawater can be obtained even in winter and has the advantage that water can be taken from land. However, the temperature varies greatly depending on the day and night and the season, and contamination of various organisms including plankton and algae has been pointed out. In order to remove these organisms, it is necessary to mix drugs.

Accordingly, an object of the present invention is to provide an onshore aquaculture system that uses water that is optimal for onshore aquaculture , particularly in a tuna onshore aquaculture system.

An onshore aquaculture system according to the present invention includes an aquaculture tank installed on land, an onshore aquaculture water suitable for onshore aquaculture, and a drain for draining the onshore aquaculture water provided in the aquaculture tank. the aquaculture tank, the outer shape includes a straight portion in particular a waterway for circulating the constant width, the bottom of the aquaculture tank is corrugated, the aquaculture tank, waterway before Symbol waterway upper A plurality of light sources for irradiating the light source are arranged along the entire water channel so that an arbitrary part can be irradiated, and the light source has an external light illuminance sensor so that the external light is lit at a certain illuminance or less. In the terrestrial aquaculture system to be set, the aquaculture tank includes a plurality of additional light sources for irradiating the side of the water channel in the direction of the water channel along the entire water channel, and each light source is continuously connected at a speed corresponding to the water flow. It is characterized in that it is configured to allow flashing Te .

The land-based aquaculture water is groundwater. Further, the onshore salmon aquaculture water may be deep ocean water, and the onshore salmon aquaculture water is a microbubble- containing water.

  Subsequently, the aquaculture tank is characterized in that its outer shape is a circulating water channel having a certain width, and in particular, an arc shape other than the straight portion.

  Further, the aquaculture tank is characterized in that the outer shape is a circulating water channel having a constant width, and in particular, the shape other than the straight portion is a polygonal shape.

  In addition, the aquaculture tank is a circulating water channel having a constant width, and pipes for supplying gas to the bottom of the water channel have the same length as the water channel width and are arranged over the entire water channel at regular intervals. And it is set so that gas can be discharged into water from an arbitrary pipe.

  Next, the aquaculture tank is a circulating water channel having a constant width, and an automatic feeding machine provided in the water channel and a fish detection optical sensor disposed in front of the automatic feeding machine, and the fish detection optical sensor detects the fish. Sometimes set to feed food in front of the fish.

  The aquaculture tank may be grown at room temperature during growth, and may be grown at a low temperature immediately before shipment.

By practicing the present invention, the tuna terrestrial aquaculture system can be used by using water that is particularly suitable for terrestrial aquaculture. In addition, the temperature does not change greatly depending on the day and night and the season, and because there is no contamination of various organisms including plankton and algae, the pathogenesis of pharmaceuticals can be reduced to prevent the development of cultured fish and eliminate these organisms. There is no need to mix.

  Embodiments of the present invention will be described below with reference to the drawings.

  A first embodiment of the land-based aquaculture system according to the present invention will be described with reference to FIGS. 1 and 2 show an oblong land culture system 2 that is coupled to each other at long sides. The oval land culture system 2 includes oval water tanks 4 and 6, arc-shaped portions 8, 10, 12 and 14, long-side portions 16 and 18, and a coupling portion are long-side portions 20. 10 and the long sides 16 and 20 form an oval 4, and the arcuate portions 12 and 14 and the long sides 18 and 20 form an oval 6. In the center of the ellipses 4 and 6, Nakasu portions 22 and 24 are provided, and a circulating water channel having a long straight line portion is formed. The long sides 20 are provided with sluices 26 and 28 at their ends. The sluices 26 and 28 are through-gate sluices as shown in FIG. By opening the sluices 26 and 28, fish and the like cultivated can freely move from one aquarium 4 to the other aquarium 6. To stop moving, close the sluice.

In Example 1, underground seawater is used as land-based aquaculture water. Underground seawater is seawater spent permeability reducing layer from waters seabed, for which a free oxygen, none aerobic bacteria. Generally, in order to sterilize seawater, it is necessary to use ultraviolet light, ozone, etc., but groundwater does not have such a need. Furthermore, since it is groundwater, the temperature is constant throughout the year. Water intake is done by wells. The groundwater that has been taken in is directly put into the oval tanks 4 and 6. Many underground seawater has a constant water temperature in the range of 17 to 19 ° C. There are not many places in the country where seawater can be taken. This aquaculture using groundwater is low-cost, safe and secure, and may be certified by HACCP. Oxygen is supplied for aquaculture. More preferably, the concentrated oxygen having an oxygen saturation of 60% or more is supplied.

  Example 2 of the land-breeding aquaculture system according to the present invention will be described with reference to FIG. Only differences from the first embodiment will be described. In the land-based aquaculture system 30 according to the second embodiment, the ellipse tanks 32 and 34 are arranged with a certain distance. Opposite ends of the oval tanks 32 and 34 are opened to provide sluices 42 and 44, and the sluices 42 and 44 are connected to each other by a water channel 36.

  In this embodiment, deep sea water is used as the onshore aquaculture water. The deep ocean water is generally seawater at a depth of 200 m or less which is not reachable by the sun, and has excellent resource properties such as eutrophication, cleanliness, low water temperature, and water quality stability. Since it is collected in the deep sea that is offshore from the continental shelf, a method of collecting by taking a water intake pipe from the land and a method of collecting by pumping up by a sampling ship are adopted. The collected deep ocean water is directly fed into the oval tanks 32 and 34.

  Embodiment 3 of the land-breeding aquaculture system according to the present invention will be described with reference to FIG. Only differences from the first embodiment will be described. In the land-based aquaculture system 50 according to the third embodiment, the bottom 60 of the sluice 58 is set higher than the bottom of the oval tank 52. Specifically, the height of the bottom portion 60 is a height that can maintain a water level that allows the fish being cultivated to move around, and the height is the normal water surface height 56 of the oval tank 52.

  On the other hand, in order to move aquaculture fish to and from the other aquarium 62 through the sluice, the water level is set to a level of the water level 54 that is much higher than the sluice 58. It is possible to facilitate the movement by raising the water level only when the cultured fish is moved, and to prevent the cultured fish from being mistakenly moved when the cultured fish is not moved. Here, the sluice gate can be used without using a through gate or the like.

  In the present embodiment, microbubble water is used as the onshore culture water. In the nanobubble disclosed in Japanese Patent Application Laid-Open No. 2005-245817, when the diameter of the microbubble is reduced to 50 to 500 nm in the process of rapidly reducing the microbubble, The charge density is increased and an electrostatic repulsive force is generated, the reduction of the microbubbles is stopped, or in the process of rapidly reducing the microbubbles, the ions adsorbed on the gas-liquid interface are electrostatically charged. By attracting both ions having opposite signs attracted into the solution in the vicinity of the interface to a high concentration in a minute volume, the ions act as a shell surrounding the microbubbles, and The ions adsorbed on the gas-liquid interface are stabilized by the gas in the bubbles being stabilized by inhibiting the diffusion into the solution. In the process of stabilizing nanobubbles by using electrolyte ions in solution as ions attracted to the vicinity of the interface, such as hydrogen ions or hydroxide ions, or in the process of rapidly reducing the microbubbles The internal temperature of the microbubbles is rapidly increased by mechanical compression, and is more effectively achieved by stabilizing the microbubbles by applying a physicochemical change accompanying an ultrahigh temperature around the microbubbles.

  In order to generate nanobubbles, microbubbles are generated in a container (not shown) containing an aqueous solution using a microbubble generator.

  Next, an electrolyte of iron, manganese, calcium and other minerals is added, and the electrolyte is added so that the electric conductivity of the aqueous solution becomes 3 mS / cm or more.

  Using an electric discharge generator (not shown), the aqueous solution containing microbubbles in the container is discharged in water. This underwater discharge generates a nanobulb.

  Water containing a large amount of oxygen nanobubbles has the effect of improving the adaptability of fish and shellfish to environmental changes and rapidly recovering debilitated individuals. In the investigation of effects on freshwater and seawater fish, almost all of the fish that were weakened during capture recover rapidly in water containing nanobubbles with a salinity of about 1%. In addition, over 30 species of freshwater fish such as bream and goldfish and saltwater fish such as bream and flounder coexist in the same tank over a period of 6 months or more in a wide range of salt concentration environment of 0.5 to 1.5%. It is possible to raise them.

  Embodiment 4 of the land-based aquaculture system according to the present invention will be described with reference to FIG. Only differences from the first embodiment will be described. In the land-based aquaculture system 64 in the fourth embodiment, oval tanks 66 and 68 similar to those in FIG. 1 are arranged. Further, the long circular water tanks 66 and 68 are arranged in a row. On the oval aquarium 66, the illumination is arranged in an oval shape from 70 which is farthest from the sluice 69 to 82 which is closest to 72, 74, 76, 78 and 80 on one side and the other is from the farthest 70 in the reverse direction Up to the illumination 90 closest to 84, 86, 88 is arranged. Also on the oval water tank 67, illuminations 92, 94, 96, 98, 100, 102, 104, 106, 108, 110 are arranged counterclockwise.

The land-based tuna farming system 64 of Example 4, in the case of tuna with a habit of farmed fish like dislike bright light dark black, through a sluice 69 from one oval aquarium 66 to the other oval aquarium 68 These cultured fish can be guided from the oval tank 66 to the sluice 69 for movement.

  Specifically, all the lights 70 to 110 of the oval tanks 66 and 68 are initially turned on. Subsequently, in order from 70 which is farthest from the sluice 69, one is turned off in the order of 72, 74, 76, 78, 80, and the other is turned off in the order of 84, 86, 88, 90 and finally the light 82 is turned off. . The farmed fish moves to a bright area where the lights are lit so that the lights are turned off.

  Therefore, it is possible to easily move the cultured fish between the aquariums by opening and closing the sluice and turning off the lighting.

  Further, in the fourth embodiment, when the oval water tanks 66 and 68 are arranged outdoors, or when the oval water tanks 66 and 68 are arranged so as to be able to collect outdoor light, an illuminance sensor is provided in the oval water tanks 66 and 68 so that the illuminance of the outdoor light is increased. When monitoring and lower than a predetermined illuminance, for example, 500-1500 lux, the light source may be set to be turned on.

  Embodiment 5 of the land-based aquaculture system according to the present invention will be described with reference to FIG. Only differences from the first embodiment will be described. The onshore aquaculture system 112 in the fifth embodiment is provided with oval tanks 113 and 114 similar to those in FIG. Of these, the oval tank 113 is provided with an air curtain in the fifth embodiment. The air curtain provided in the ellipse water tank 113 will be described.

  For the air curtain, a vinyl chloride pipe is attached to the end of a distribution pipe that supplies gas such as oxygen and air, and a gas discharge hole is provided on the top surface of the vinyl chloride pipe at a predetermined interval and arranged on the bottom of the water tank. It is a device that discharges gas into water in a plane.

  The air curtain 118 is disposed at a portion farthest from the sluice 117 provided at the end of the oval water tank 113, and the air curtain 120 is disposed on the water channel sandwiched between the long side walls 115 and 116 from the side opposite to the sluice 117. , 122, 124, 126 and 128 are arranged. Further, the air curtain 130 is also disposed between the other long side walls 119 and 121 at a portion farthest from the sluice 117, and the air curtain 140 is disposed at 132, 134, 136, and 138 and the sluice portion.

Recognized for this air curtain, tuna compound having a constant sight wall present in the water. For this reason, if these farmed fish discover an air curtain, they will take an avoidance action. Note that the air curtain also has an effect that no damage such as thread occurs even if the cultured fish collides.

  Moreover, it is preferable to comprise the bottom face of the ellipse water tank 113,114 in a waveform. This is because when the water flow is generated, the water flow changes the flow direction by the corrugated bottom surface and rolls up the sinking food. This is because when the bait is rolled up, the cultured fish of the moss eats the bait again, and it is possible to prevent the water from becoming polluted by being wasted or being left to rot.

  Next, the operation of the fifth embodiment will be described. First, since there is usually a water flow, none of the air curtains release any gas. Subsequently, when the water flow is stopped and the sluice 117 is opened in FIG. 6 to move the cultured fish from the oval tank 113 to the oval tank 114, first, gas is supplied to the air curtains 118 and 130 farthest from the sluice 117. To activate the air curtain. As a result, the cultured fish moves to the air curtains 120 and 132 in the direction of the sluice 117, which is opposite to the air curtains 118 and 130, avoiding contact with the air curtains 118 and 130.

  Subsequently, the air curtains 120 and 132 are sequentially operated from the air curtains 120 and 132 at a speed at which the cultured fish is not left behind, and then moved to the air curtains 122 and 134. Then, the air curtains 122 and 134 are operated to operate the air curtains 124 and 136. Move to the side. Further, following the air curtains 126 and 138, the cultured fish is driven between the air curtains 128 and 138. Finally, the air curtain 140 can be operated to move completely from the oval water tank 113 to the oval water tank 114, and the sluice 117 can be closed. In either case, the movement is completed without causing thread in the cultured fish to use the air curtain.

  In addition, if this air curtain is utilized synchronizing with the illumination of Example 4, cultured fish can be moved more effectively.
