Description

  TECHNICAL FIELD The present invention relates to a cultivation apparatus that can be installed on land and cultivated on a year-round, and can be harvested every day, such as clams and sasabinori. Moreover, this invention relates to the cultivation method which can cultivate year-round by a raw spore, without relying on a filamentous body for Amanori.

The sea bream cultivated on the coast of Japan is mainly an improved variety mainly of Susabinori and its strains, which are seaweeds belonging to red algae called Amanori. Many Amanoris are based on a life cycle consisting of two forms, a period when they exist as leaves and a period when they exist as filaments. Sperm and egg-forming machine formed on mature leaf bodies are fertilized, go through sac and become fruit spores, which are released into the sea. The fruit spores attach to the seashell and germinate to enter the shell and form filaments. As the filaments mature, they meiosis and form shell spores that are released. This drifts in the tide and attaches to the nets and rocks to germinate and grow into leaf bodies. The leaves grown from the shell spores grow while releasing the original spores and reach the maturity stage.
Currently, in most production areas in Japan, fruit spores are artificially attached to rice husks, etc., and shell spores are released from filaments grown under the control of the cultivation facility, and are cultivated on land or at sea. Seeds are attached to the net (attaching shell spores) to make seedlings for laver culture.

(Patent Document 1) describes a method for culturing filamentous bodies of marimo, which is a kind of green algae.
(Patent Document 2) discloses a technique for facilitating seeding by giving monospores (same meaning as protospores) positively from the fronds by stimulating them, and attaching them to the carrier. Yes.
(Patent Document 3) is a seaweed comprising experimental facilities for growing spores, a plurality of sleeves for maturing the spores, and a plurality of small inoculation tanks containing seawater to which nutrients are added, and a plurality of large culture tanks. A system for aquaculture of potatoes is disclosed.
(Patent Document 4) discloses an apparatus and a method for performing forced cultivation by performing environmental control most suitable for algae growth in an artificial environment of dissolved gas, light, temperature, nutrient source, and sanitary environment.

However, the above conventional techniques have the following problems.
(1) Since the release of husk spores occurs only in a limited season, there was a problem that seeding could affect the yield of the year and stable production could not be achieved.
(2) Since the growth of laver is left to the natural environment, there is a problem that it is easily affected by climate change and the quality and production volume are not stable.
(3) Harvesting of laver in the farm is a difficult task on the sea in winter, and there is a problem that efficiency and integration are difficult.
(4) Since the technique described in (Patent Document 1) specializes in marimo filamentous bodies, there is a problem that it cannot be diverted to Amanori.
(5) The technique described in (Patent Document 2) does not use shell spores from filamentous bodies but uses monospores (protospores) from fronds (leaf bodies). Only the method of stimulating the frond is described, it is not described about the configuration and cultivation method of a specific cultivation apparatus for growing the frond using a carrier to which protospores are attached, The breeding method after seeding was the same as before, and it was easily affected by climate change, and there was a problem that the quality and production volume were not stable.
(6) The technology described in (Patent Document 3) and (Patent Document 4) requires separate aquarium equipment for each growth stage of Amano in order to use it for aquaculture production, There is a problem that it is difficult to improve workability and productivity, and that, when trying to harvest every day, the number of facilities multiplied by the number of days of growth is required and a great investment is required.
(7) Since conventional laver cultivation is premised on the production of dry seaweed, it is torn at the time of harvest and carved into small leaf pieces, so there is a problem that the freshness of laver is remarkably deteriorated and the taste of laver is also significantly reduced. .
(8) In the conventional technique, leaf bodies having different maturity stages exist simultaneously on the laver net, so they are harvested while being mixed. However, Amanori has a feature that nutrients and umami components do not accumulate unless they are in a mature stage, and there is a problem that the quality changes depending on the proportion of leaf bodies at different stages of maturation.

  This invention solves the said conventional subject, and it aims at providing the cultivation apparatus of Amanori which was not influenced by natural environment and was excellent in workability | operativity and productivity. Also, to provide a method for cultivating Amanori, which can obtain seeds and seedlings continuously throughout the year, has a good freshness, has a good taste, has a stable growth stage, and can harvest stable quality paste. With the goal.

In order to solve the above-mentioned conventional problems, the apparatus for cultivating a flounder and the method for cultivating a flounder using the same of the present invention have the following configurations.
The apparatus for cultivating Amanos according to claim 1, wherein the shell spores or protospores of Amanos are attached to a leaf body holding member formed in a string shape, a string shape, a rod shape or a belt shape, and the shell spore or the protospore. An apparatus for cultivating flax and growing leaf bodies, comprising a cultivation liquid supply unit, a cultivation tank for flowing the cultivation liquid supplied from the cultivation liquid supply unit from the upstream side to the downstream side, and the cultivation An interval adjusting unit that is formed from the upstream side to the downstream side of both sides of the tank and that detachably holds both end portions of the leaf body holding member and adjusts the interval between the plurality of leaf body holding members. It has a configuration.
With this configuration, the following effects can be obtained.
(1) By having a cultivation tank that causes the cultivation liquid supplied from the cultivation liquid supply part to flow down from the upstream side to the downstream side, the surface of the leaves of the sea cucumber cultivated in the cultivation tank is washed by the flow of the cultivation liquid. It is difficult for dirt and the like to adhere, and the Amanori can continue to grow well.
(2) Since it has an interval adjusting unit that is formed from the upstream side to the downstream side of both sides of the cultivation tank and that detachably holds both ends of the leaf body holding member and adjusts the interval between the plurality of leaf body holding members, The spacing between the leaf body holding members can be easily adjusted according to the growth of the leaf bodies, and the leaf bodies attached to adjacent leaf body holding members are prevented from overlapping and becoming shaded, and the growth is average. Proceed to
(3) Since the both ends of the leaf body holding member can be detachably held by the interval adjusting unit, the leaf body holding member can be easily moved while maintaining a certain length, and the leaf body holding member is attached and detached. Excellent workability.
(4) Since the spore sprouting from the spore or protospore releases protospore at the bud stage, a new spore holding member with no spore or protospore attached to the most downstream side of the interval adjusting part is provided. By holding and holding the leaf body holding member with the leaf body attached to the upstream side, the spore can be attached to the new leaf body holding member on the most downstream side, and the seeding workability is excellent.
(5) Since the interval between the plurality of leaf body holding members can be adjusted by the interval adjusting unit, the leaf body holding member is moved to the upstream side according to the growth of the leaf body, and the leaf body holding the small leaf body is attached. By efficiently holding a plurality of leaf body holding members in the entire cultivation tank by holding the member on the downstream side of the cultivation tank and holding the leaf body holding member to which a large leaf body is attached on the upstream side of the cultivation tank. The leaf body holding member to which only a sufficiently grown leaf body is attached is recovered from the upstream side and harvested efficiently without the leaf bodies having different growth states being simultaneously present on one leaf body holding member. be able to.

Here, the material of the leaf body holding member can be appropriately selected. However, when a membrane-like material such as a filter cloth having water permeability and water permeability is used, the original spores flowing down with the cultivation liquid are It easily penetrates into and adheres to the inside (gap) of the leaf body holding member and has excellent seeding reliability. For example, a fiber or the like formed by twisting fibers or the like, a woven fabric, a nonwoven fabric, a net or the like cut into a string or a band, and the like are preferably used. It can also be used in the form of rods or strips made of synthetic resin or wood, etc., but it can also be easy to attach spore by forming irregularities on the surface or drilling micro holes it can. Alternatively, a woven fabric, a non-woven fabric, a net, or the like may be wound around a rod-shaped member made of synthetic resin or wood.
In addition, when forming a leaf body holding member in rod shape or strip | belt shape, it is preferable to select thickness and a width | variety so that it may not become resistance of the culture solution which flows down.

The cultivation liquid supply part should just be what can supply the cultivation liquid required for the growth of a leaf body to a cultivation tank. As the culture solution, a solution obtained by adding carbon dioxide gas to seawater or brackish water, or adding fertilizer components such as nitrogen, potassium, and phosphorus is suitably used.
The culture solution supply unit is preferably installed in a place where light is blocked in order to prevent the propagation of other algae or the like, or preferably includes a lid that can block light. Also, in order to prevent plankton and shellfish from entering the cultivation tank, it is filtered through the filtration unit before injecting seawater or brackish water into the cultivation solution supply unit or before supplying the cultivation solution from the cultivation solution supply unit to the cultivation vessel. It is preferable to do.
In addition, it is preferable that a cultivation liquid supply part has a temperature adjustment part for setting the water temperature of cultivation liquid (or seawater or brackish water) to desired temperature. By maintaining the water temperature of the cultivating solution at 5 to 22 ° C., the leaves can be cultivated healthy throughout the year.

  The total length of the cultivation tank can be appropriately selected according to the growth rate of the cultivated Amanori, the size (length) of the leaf bodies at the time of harvest, and the harvest cycle. For example, in the case of Susabinori, after growing from a spore to a leaf body of about 1 cm in the first month, the length grows at a daily growth rate of 20%. Therefore, when harvesting at a pace of about 50 cm once a week, a length of about 80 cm to 1 m is required in order to arrange the leaves of each growth stage attached to the leaf body holding member so as not to overlap each other. Necessary. Moreover, when harvesting every day, the length of 3.5m-5m is required.

Although the length of a leaf body holding member is substantially equivalent to the lateral width of a cultivation tank, since it normally works by 1-2 persons, it is preferable to make it within 1 m. This is because if it exceeds 1 m, it becomes difficult to handle the leaf body holding member during movement or harvesting of the leaf body holding member. The holding interval of the leaf body holding member can be appropriately selected according to the growth state of the leaf body so that the leaf body does not overlap the downstream leaf body. This is because when the leaf bodies overlap, the upper leaf body blocks light and prevents the lower leaf body from photosynthesis, thereby inhibiting its growth.
The fixing method of the leaf body holding member to the interval adjusting unit can be appropriately selected. A method of attaching weights and retaining members on both ends of the thread-like or string-like leaf body holding members and dropping the inside of each weight or locking member into the groove on the side wall, It is possible to use a method in which both ends are tied to a protrusion formed on the side wall or sandwiched with a clip or the like and fixed. Moreover, both ends of the rod-shaped leaf body holding member can be fixed by fitting the slits on the side walls.

The material of the cultivation tank can be selected as appropriate, but when the inner surface (bottom surface) is mirror-finished or the reflector is laid on the bottom surface, the light irradiated to the cultivation tank is reflected on the bottom surface. Reflected light can also be used for photosynthesis to promote growth, and the use efficiency of irradiation light is excellent. Therefore, as the material of the bottom part of the cultivation tank, stainless steel that is hard to rust and reflects light is particularly preferably used.
It is preferable to adjust the supply amount of the cultivation liquid and the inclination angle of the bottom of the cultivation tank so that the flow rate of the cultivation liquid in the cultivation tank is 5 to 15 cm / second. As the flow rate of the cultivation liquid becomes slower than 5 cm / sec, even if the fertilizer component of the cultivation liquid is enriched, the growth of the leaves of Amanori tend to be suppressed. There is a tendency that the body is damaged or cut and the quality and yield are liable to decrease, both of which are not preferable.
Although the installation place of a cultivation apparatus can be selected suitably, the place where seawater and brackish water are easy to obtain is used suitably. In addition, if the indoor space is closed and sealed with sunlight, it is easy to adjust and manage light irradiation conditions and temperature / humidity conditions that are optimal for the growth of leaves, and it is excellent in productivity and uniformity of quality.

  Basically, this cultivating apparatus for the flounder is based on the realization of a stable harvest throughout the year without relying on the shell spores released from the filaments by using the original spores released from the leaves. If necessary, select more mature leaves and mature them, release shell spore from the filamentous germination, and use them to obtain more good quality leaves Can improve productivity and quality.

Here, the water depth of the cultivation tank can be appropriately adjusted according to the growth state of the leaf body so that the leaf body in the culture solution is not exposed to the air, but the leaf body from the downstream side where the leaf body is small. It is preferable to select in the range of 0.2 cm to 10 cm over the upstream side where the sap grows greatly.
As the water depth on the downstream side of the cultivation tank becomes shallower than 0.2 cm, the leaf body holding member for adhering protospores and the newly germinated leaf body are easily exposed to the air. There is a tendency that the growth of the body is hindered, and as the upstream water depth becomes deeper than 10 cm, the amount of the cultivation liquid increases unnecessarily, and the efficiency of cultivation and the resource saving tend to be reduced. Neither is preferred.

Thereby, the water temperature of the cultivation liquid 20 can be maintained at 5-22 degreeC, and a leaf body can be brought up healthily throughout the year.
Although the material of the cultivation tank 11 can be selected suitably, the bottom part 11a was hard to rust and was formed with the stainless steel which reflects light. This is because the light irradiated to the cultivation tank 11 is reflected by the inclined surface 11b, and the reflected light can also be used for photosynthesis to promote the growth, and the efficiency of using the irradiated light is excellent.
In addition, the reflectance of irradiated light can also be improved by mirror-finishing the inner surface (inclined surface 11b) of the cultivation tank 11, or laying a reflector on the surface of the inclined surface 11b.

Next, the detail of the cultivation tank in the cultivating apparatus of the Amanori of Embodiment 1 is demonstrated.
Fig.2 (a) is a partial plane schematic diagram of the cultivation tank in the cultivation apparatus of the Amanori of Embodiment 1, and FIG.2 (b) is an AA arrow directional cross-sectional schematic diagram of Fig.2 (a). .
In FIG. 2, 25 is formed from the upstream side to the downstream side of both sides of the cultivation tank 11, and both ends of a leaf body holding member 50 described later are detachably adjusted to adjust the interval between the plurality of leaf body holding members 50. The interval adjustment unit 26a is a support plate of the interval adjustment unit 25 placed on the inclined surface 11b of the cultivation tank 11, and the interval adjustment 26b is arranged on the support plate 26a in parallel with the longitudinal direction of the cultivation tank 11. The base part of the part 25, 26c is a plurality of protrusions of the interval adjusting part 25 formed in a comb-teeth shape so as to protrude above the base part 26b, and 26d is formed in a slit shape at the center in the width direction of the protrusion part 26c. A plurality of holding member mounting portions 50 of the gap adjusting portion 25 are thread-like, string-like, belt-like, or rod-like, each of which has both ends locked to the holding member mounting portion 26d and stretched between the left and right gap adjusting portions 25. The leaf body holding member 51 is provided on both sides of the leaf body holding member 50. A weight attached to the holding portion 26d to engage with the protrusions 26c on both sides of the holding member mounting portion 26d to prevent the leaf body holding member 50 from falling out of the holding member mounting portion 26d, and 60 is an amanori attached to the leaf body holding member 50 It is a leaf body of the class.

The water depth of the cultivation tank 11 can be appropriately adjusted according to the growth state of the leaf body 60 so that the leaf body in the cultivation liquid 20 is not exposed to the air. It selected in the range of 0.2 cm-10 cm over the upstream where the body 60 grows large.
As the water depth on the downstream side of the cultivation tank 11 becomes shallower than 0.2 cm, the leaf body holding member 50 for adhering the original spores and the newly germinated leaf body 60 are easily exposed to the air. Germination and growth of the leaf body 60 tend to be inhibited, and as the upstream water depth becomes deeper than 10 cm, the amount of the cultivation liquid 20 increases unnecessarily, and the efficiency and resource saving of the cultivation tend to decrease. This is because it was found that there is a tendency to become.

The fixing method of the leaf body holding member 50 to the interval adjusting unit 25 is not limited to the present embodiment, and can be appropriately selected according to the material, shape, and the like of the leaf body holding member 50. Both ends of the thread-like, string-like, or belt-like leaf body holding member 50 may be passed through the holding member mounting portion 26d, and then wrapped around the projection portion 26c, or both ends of the leaf body holding member 50 may be projected. It may be fixed with a clip or the like together with the portion 26c. Moreover, when the leaf body holding member 50 is formed in the rod shape which has rigidity, the both ends of the leaf body holding member 50 can be fitted to the holding member mounting part 26d, and it can fix simply.
The interval between the holding member mounting portions 26d can be selected as appropriate, and may be formed at regular intervals (constant) from the downstream side to the upstream side, or may be formed so as to gradually widen from the downstream side toward the upstream side. May be. In any case, by selecting the installation position of the leaf body holding member 50 in accordance with the growth of the leaf body 60, the interval between the adjacent leaf body holding members 50 can be adjusted.
In addition, if a scale etc. are provided in the outer side part of the side wall part 11c of the cultivation tank 11, the space | interval of the leaf body holding member 50 can be easily adjusted on the basis of it, and it is excellent in usability.

The material of the leaf body holding member 50 can be selected as appropriate. However, when a membrane-like material such as a water-permeable or water-permeable filter cloth is used, the original spores flowing down together with the cultivation liquid 20 are leaves. It easily penetrates into and adheres to the inside (gap) of the body holding member 50 and has excellent seeding reliability. For example, a fiber or the like formed by twisting fibers or the like, a woven fabric, a nonwoven fabric, a net or the like cut into a string or a band, and the like are preferably used. In addition, when the leaf body holding member 50 is formed into a rod shape or a belt shape with synthetic resin or wood, it is possible to make the spore adhere easily by forming irregularities on the surface or drilling micro holes. . Alternatively, a woven fabric, a non-woven fabric, a net, or the like may be wound around a rod-shaped member made of synthetic resin or wood.
In addition, when forming the leaf body holding member 50 in the shape of a rod or a belt, the thickness and width were selected so as not to be the resistance of the cultivation liquid 20 flowing down.

A method for cultivating Amanori using the apparatus for cultivating Amanori of Embodiment 1 of the present invention configured as described above will be described.
First, one or a plurality of leaf body holding members 50 to which shellfish spore or progenitor spores are attached in advance are fixed to the holding member mounting portion 26d on the downstream side of the interval adjusting portion 25, and the cultivation liquid 20 in the cultivation tank 11 is obtained. Soak in.
The cultivation liquid 20 is made to flow down from the upstream side of the cultivation tank 11 to the downstream side while appropriately supplying fertilizer components and carbon dioxide.
The light irradiation unit 15 adjusted the photosynthetic photon flux density in the range of 50 to 80 μmol / m ² / s, and irradiated the cultivation tank 11 with light for 8 to 14 hours per day. This is because if it falls below this range, the amount of photosynthesis is insufficient and the growth tends to be slow, and if it exceeds this range, it has been found that strong light damage tends to occur.
In addition, while not irradiating light from the light irradiation part 15, the cultivation liquid 20 does not need to flow down.

When shellfish spores or protospores attached to the leaf body holding member 50 germinate, move to the upstream side of the cultivation tank 11 while increasing the spacing between adjacent leaf body holding members 50 as the leaf body 60 grows. Let
A new leaf body holding member 50 to which shell spores or protospores are not attached is fixed to the holding member mounting portion 26d on the most downstream side of the interval adjusting portion 25, and the holding member mounting portion on the upstream side of the interval adjusting portion 25 is fixed. Prospores released by the leaf body 60 attached to the other leaf body holding member 50 held in 26d at the time of bud are attached. When the original spore germinates, it moves to the upstream side of the cultivation tank 11 while adjusting the interval together with the other leaf body holding member 50 in accordance with the growth of the leaf body 60.
When the leaf body holding member 50 moves to the most upstream side and the leaf body 60 is sufficiently matured, the leaf body holding member 50 is removed from the holding member mounting portion 26c and harvested.

Initially, the leaf body holding member 50 to which shell spore or protospore is previously attached is necessary, but after sprouting from the shell spore or protospore and the leaf body 60 starts growing, the leaf body 60 is in the bud stage. Since the protospores to be released can be used, seeding is performed sequentially by adding a new leaf body holding member 50 to which shell spore or protospore is not attached, and the leaf body 60 is germinated. It is possible to cultivate Amanori semipermanently.
In addition, as needed, the new leaf body holding member 50 in which the spore spores and the original spore are not attached to the cultivation liquid 20 stored in the collection tank 12 is immersed and stirred to leave the original spores in the cultivation liquid 20 as leaves. The body holding member 50 may be attached to the body holding member 50 securely and sufficiently, and may be attached to the most downstream side of the interval adjusting unit 25.
By using the leaf body holding member 50 seeded in this way, it is possible to increase the number of clam cultivation devices 1 and increase the production amount.
Moreover, since the spore which did not adhere to the leaf body holding member 50 is contained in the cultivation liquid 20 stored in the collection tank 12, the drainage valve 13a is opened and the cultivation liquid 20 drained from the drain pipe 13 is preserved. In addition, it can be used for seeding as required.
