Description

  Omniphagous marine fish feed on plant foods such as green algae, red algae, and brown algae, and animal foods such as small fish, shellfish, shrimp, crab, hermit crab, and sea bream. Feed and act. When picking up seawater fish such as medina, black sea bream, red sea bream, sea bream, and sea bream, it is common to hook them with animal food such as krill. The fishing method is uki fishing, using a rod and reel tool, and attaching a reel, uki, sarkan, harris, and a hook to the reel. There is also a case where a weight is attached between the ground and the hook. Select fishing tools and devices according to the season, fishing environment, and the type and size of the target fish. When the installation of the device is finished, mainly the half-thawed krill food or the mixed food mixed with mixed feed and seawater is thrown into the sea all day, and the target fish is drawn. A bait (hereinafter referred to as “sashie”) that is inserted into a fishhook so as to be synchronized with the bait is added to the target fish habitat layer (hereinafter referred to as “tana”), and the crowded bait It is a fishing method to bite. Sashie is the same krill as the bait, but in order to improve the atari of the target fish, the raw krill is used in most cases rather than frozen, and rarely boiled krill is used.

  However, raw krill is good not only for the target fish but also for other fish, such as fish other than the target fish, which are called prey fish. When using boiled krill, there are things that float on the surface of the sea, so you must immerse in the sea the day before fishing and soak in the sea. In order to prevent these krills from rotating in the sea and to avoid the wrapping of Harris, both the raw and boiled krill must be cut off. Krill is easy to come off the fishhook when it is put into the device or underwater, so you should choose a krill that is tight and firm, and if you don't use a sachet that matches the size of the fishhook you use, Not only does it come off the fishhook, but it also hides the fishhook itself, making the target fish cautious of the fishhook and making it difficult to eat. In addition, many fish that respond to shining fish are reflected in the fish, and some fish hooks that are not completely hidden by the bait are reflected in the light. Making it more difficult to catch. While paying attention to these, drop the sachet to the target point using the weight of the sea urchin, road string, Harris, fishhook, sachet, and weight, and aim to synchronize the sash that sinks in the sea with the bait. Reach Tana and wait for Atari. However, there are some major problems that cannot be solved at the root of this fishing method.

  First, if the fisherman comes off the hook while dropping the sachet, the angler can recognize this when he pulls up from the sea and looks at it. The angler who waits for Atari even while the sachet is off the hook, is there no fish originally in the sassie tana, whether the sage tana is wrong, or whether the sachet and the bait are out of sync, Not only can it be confirmed whether the sachet is already eaten by bait, whether the sachet is already out of the hook, or missed the target fish's clam, it will be a waste of time.

  Next, while the dropped sassier sinks into the sea and reaches Tana, it is a fish other than the target, such as horse mackerel, mackerel, izuzumi, takabe, red pepper, sparrowfish, kitamakura, pufferfish, or even a small fish There is a problem that is more difficult to solve than the beginning, such as the possibility of being eaten by prey fish. The target fish is devised so that it does not eat the sachet by changing the point where the bait is hit, adjusting the speed at which the bait sinks, adjusting the timing when the bait and the mechanism are dropped It takes a considerable number of bait and sasiel drops to catch the fish. In this fishing method, the time when the bait reaches the target point is measured, and when the sassie is thrown in, taking into account natural conditions such as tide and wind, the time until the thrown sachet reaches the target tana is matched. The skillful technique called is required.

  In addition, when throwing sassier to the target point, it is dropped using the weight of road thread, snow, sarkan, and weight, but in the case of road thread, the buoyancy that floats on the sea surface is reduced to reduce the influence of wind. Use road threads that sink in seawater with low buoyancy, not large road threads. In addition, heavier, moreover, salkan, and fishing hooks are used, but the fishing hook and bait alone at the tip of the device are not enough for their own weight. Therefore, when wind is particularly strong, when raining, etc., Harris is entangled when dropping, and when the tide is strong, Harris is often entangled in the sea. Also, under these circumstances, the sinking of the bait in the sea will worsen, so it is necessary to put a weight between the sea urchin and the hook to allow the sassier to reach the target tana in the sea to synchronize with the bait. Come out. However, it is best to make the uki as small as possible in order to improve the mouth feel of the target fish. On the other hand, the uki must be enlarged according to the weight, so it is difficult to catch the target fish. Also, if you want to quickly sink the sash to the target tana or drop the sash to a deep tana, it is necessary to make the road thread and weight more heavy, so there is a problem that the target fish becomes more vigilant and bites the sash is there. Especially when the tide is strong, it is important to improve the weight and weight of the deer even if it is not suitable for the target fish. There is also a problem that it becomes easy.

  The weight of the weight that is used varies depending on the manufacturer, but as a guideline, the round crushing weight that is attached to Harris is 0.55g, 0.85g, 1.00g, 1.30g, 1.65g, 1.90g. It is divided up to about. Adjust this to match the target Tana, and attach one or two to Harris. In addition, in order to adjust the throwing distance even with the weight of the ground, about 5m for the 3-5g ground, 15m for 6-8g, 20m for 7-10g, and 30m for 10g. In this fishing method, it is important to grasp the tana of the target fish and to remove the slack of the road line, especially Harris, in order to make the fish's atari react sensitively to the ground. With a light bait such as krill, it is difficult to create a tension without attaching a weight, but the target fish will feel uncomfortable with the presence of the weight.

  Some people feel unclean about hanging animal food on fishhooks. Instead of animal bait, a method of hooking seaweed with the same tools and devices as this uki fishing is also used, but it is rare. In that case, after picking Aonori growing in the intertidal zone from the coast, several tens to several tens of them are simply hung on the fishhook, or cotton thread is used as a bait to keep it from dropping when dropped. However, it takes time and effort to collect it, and it is dangerous to detect the warning of the person collecting the target fish during the collection. Seaweed, which is one of the original food habits, is rarely used because it is easy, and it is difficult for seaweed to conceal the entire fishhook and it is bad.

  When the present inventors actually wound raw seaweed with a thread, not only is it difficult to wind the thread due to the slimness and softness of the frond, but also the way the frond opens in the sea is not uniform I could eat the part of the frond that had no fishhook, and it was hard to catch the fish. In addition, even when dried seaweed was used and the thread was hung up so that the fishing hook was hidden and put into seawater, the frond was very difficult to open, and even when opened, it became distorted and could not catch the fish. Also, both raw and dried leaves are lightly difficult to drop and have the problems described above.

  This invention makes it a subject to provide the fishing bait for omnivorous saltwater fish or a vegetative dietary saltwater fish in order to solve such a problem. More specifically, it is an object to provide an effective fishing bait for omnivorous marine fish or phytophagous marine fish that can be used alone or in combination with seaweed.

The present invention has been made in order to solve the above-mentioned many problems, and relates to a food for omnivorous saltwater fish or vegetarian saltwater fish as follows. That is, the present invention
(1) A feed for seawater fish that attaches seaweed serving as a food to a substance serving as a three-dimensional nucleus.
(2) The feed according to the above (1), wherein the substance serving as a three-dimensional nucleus is highly hydrophilic and can be passed through a fishing hook or hooked on a fishing hook.
(3) The feed according to (1) above, wherein the seaweed serving as a bait is a seaweed belonging to the class of red algae, green algae, and brown algae.
(4) The food according to (3) above, wherein the seaweed belonging to the class of red algae is a seaweed belonging to the genus Amanori.
The fishing bait of the present invention is a fishing bait that is cultured or cultivated so that the seaweed that feeds omnivorous marine fish or vegetative marine fish adheres to a core substance and grows densely. It is possible to multiply.

  As the seaweed used in the present invention, a red alga class, a green alga class, and a brown alga class can be used, and it is preferable to use a seaweed belonging to the red alga class Udonus. Of these, it is particularly desirable to use seaweeds belonging to the genus Amanori. Among the seaweeds belonging to the genus Amanori, Susabinori, Asakusa Nori, Cronori, Maruba Amanori, Tsukushia Manori, Oniamanori, Utsutsunori, Ichimatsunori, Kosuginori, Uppuinori, Chishimarori and the like are used. In addition, it is desirable to use the genus Aonori, the genus Aegosa, the genus Aosa, and the genus Havanori in the class of brown algae.

  The life cycle of the genus Amanori produces germinal cells of the spermatozoon and the pulmonary tract in the same sexes and different strains at the edges of mature fronds from winter to spring. The fertilizer that has been fertilized splits and turns into a sac, releasing fruit spores. The fruit spores penetrate into calcareous materials such as shells, and the filaments grow from spring to autumn. The filament forms shell spores and releases them. The released shell spore adheres to the object and germinates. The tip of the germination that has grown to some extent is released as a single spore. These shell spores and monospores grow from autumn to winter, grow into fronds, and repeat the life cycle. In order to release shell spores from seaweeds of the genus Amanori into the culture solution, a method using shell spores from adult fronds was used, but a method using shell spores from filaments in shells, etc. Can also be used. In the genus Amanori, which does not release shell spores, fruit spores can also be used.

  Of the red seaweeds, it is desirable to use Susabinori. As the Susabinori, Susabinori cultured at 15 ° C to 18 ° C can be used. Susabinori is resistant to drying, so it has the advantage that it can be dried and frozen for storage. When stored frozen, seaweed adhering to the nuclear material raised from the culture solution can be dried to a weight of about 20-40% and stored at -20 ° C-30 ° C. This clean frond body is transferred into a 300 ml Erlenmeyer flask at a temperature of 25 ° C., and cultured for 3 to 4 days at 500 to 1000 lux under a white fluorescent tube to obtain 20,000 to 30,000 cells / ml of spore spores. The shell spore solution can be made to be released and cooled to 18 ° C.

  As the core material, a material having high hydrophilicity (here, a property that is easy to adapt to water, hereinafter the same) is optimal. Highly hydrophilic glass has good adhesion to shell spores and is suitable for dense foliage, and crystals can be used, but rubber is not desirable. Moreover, the shell spores adhere well like the vinylon resin used for laver culture, and a soft substance can be used as the nucleus. The shape of the substance serving as a nucleus is preferably a three-dimensional object that is stable in a spore solution, such as a cube or a rectangular parallelepiped, and that assists the adhesion of shell spores in a planar manner on top of the substance that serves as a nucleus. In the process of dry preservation of seaweed, there is a possibility that the temporary root part may be detached from the core substance, so from the point of storing a groove next to the core substance and winding a thread next to the raw frond, A cubic or rectangular parallelepiped shape is desirable because it is easy to wind a thread. Moreover, when fishing baits are hooked on these fishing baits, these shapes are desirable because they are easy to hook. If the material of the core material is soft, it can be used by rolling and molding, and beads with holes can also be used. If the nuclear material is glass, it is an 8mm square object, and 0.8g-1g will work as a weight, but it can control the sinking speed of the nuclear material in water by the difference in the weight of the nuclear material. Therefore, when adding the function as a weight more than the weight of the nuclear material, it is possible to use a metal such as lead as the core and surface processing with glass or chemical fiber. Since the thing with a high water absorption rate improves the adhesion, it is effective.

  When using beads as the core, it is important to reduce the deviation of the bait needle as well as the ease of attaching the bait to the needle. Therefore, it is desirable to use glass beads that can be passed through a fishing hook as a core substance, and to fill the holes in the beads with rubber, or to use rubber with a processed surface in the hole of the beads. As a result, the adhesion of shell spores is not seen in the rubber part, and the hole is easy to see when the fishing hook is hung, making it easy to cut the needle and preventing the needle from coming off due to fixation. The core material and hole rubber are preferably the same color as seaweed.

  A fishing hook used in the present invention is shown in FIG. FIG. 2 shows a cubic bead having a through-hole in the present invention. A indicates the diameter of the hole of the bead, and B indicates the height (length) of the bead. Figure 3 shows how the core beads and small beads were connected to the fishing line to attach the shell spores. C represents a core bead, and D represents a small bead. FIG. 4 shows a sasabinori which is one of the seaweeds used in the present invention. 5 to 7 show an embodiment of the present invention in which a substance serving as a three-dimensional nucleus to which the seaweed of the present invention is attached is passed through a fishing hook, and a conventional embodiment using krill. 5 is a side view, FIG. 6 is a front view, and FIG. 7 is a bottom view. In addition, (1) shows a fishing hook, (2) shows the feed of the present invention, (3) shows a through-hole through which the fishing hook passes, (4) shows rubber, and (5) shows a fishing line.

  When using glass beads as the core material, in order to increase the adhesion of shell spores, wash the surface with distilled water at least 2-3 times and then immerse in the same solution as the culture for 2-3 days. And good. When attaching the shell spores, as shown in FIG. 3, it is advisable to sandwich a small bead between the beads to which the seaweed is attached so that the beads as the core do not overlap. In this case, rubber or the like hits the portion where the small bead conceals the side surface of the bead. In order to pass fishing lines through these small beads, the surface is washed beforehand and handled in the same way as the core substance. In order to attach as many seaweed shell spores as possible to the beads, it is better to immerse them in the spore solution, hang them horizontally, soak the spore solution, and attach it to the upper surface of the glass more than the other surfaces while gently stirring. The time for dipping the beads is preferably at least 3 hours or more and 24 hours. The water temperature for culturing the shell spore attached to the beads is preferably 10 ° C.-20 ° C. and 18 ° C. Illumination is performed at 3000 lux for 10 hours a day, and the remaining 14 hours are not irradiated, and aeration and agitation are performed at 6 liters per minute with air once passed through another culture solution to prevent drying. And good. The culture solution should be replaced with a new one once every 3-4 days to supply nutrients, and the length of the frond body will reach 1 cm or more in about 3-4 weeks, and it should be used as food for saltwater fish. I can do it. In order to hide the fishhook so that the target fish can eat without warning, attach as much shell spore as possible to the core substance, germinate and grow, and spread the fronds in the sea as if they blossomed However, when using a frond that grows longer than the length of the fishhook, it is desirable to adjust the length of the fish because it will not catch the fish even if it catches the upper part of the needle. This can be done by cutting the top of the leaf or rounding it to the desired size with a thread.

  The present invention is practiced from room culture. This is because it is impossible for ordinary individuals to cultivate in the sea because permission is required for aquaculture using public water. However, the present invention can serve as a basis for attaching seaweed to a core substance in the open sea and using it as a seaweed food for omnivorous marine fish or herbivorous marine fish. For example, by using bead-shaped glass as the core material, connecting small beads with a thread between the glass so that they do not overlap, and tying the material immersed in the shell spore solution to the cracks in the paste farm. It is thought that the target seaweed bait can be made.

  The seaweed bait for omnivorous marine fish or phytophagous marine fish of the present invention is a fishing bait cultured or cultivated so that seaweeds adhere to a core substance and grow densely, and fishing using the fishing bait of the present invention The method can be performed alone without the need for a bait. That is, the seaweed bait for omnivorous saltwater fish or phytophagous saltwater fish of the present invention has the following advantages and is useful in fishing for omnivorous saltwater fish or phytophagous saltwater fish.

1. It takes less time like a krill hook and has a hole in the core material, so it can be easily detached from the hook, and the core material is in the hook of the hook and the hole in the bead. The device can be thrown in without being removed from the fishhook by rubber, and the seaweed frond can cover the whole fishhook in seawater.
2. Animal-eating prey fish do not feed through the mouth even if they are interested in the movement of this seaweed bait, and pass through the prey fish tana without eating seaweed. Can be reached, and there is no need for sowing bait or waste of sowing bait and sachet, saving time for catching the target fish and efficient fishing. In the conventional fishing method, if you drop the sashie first, the fish will be taken out by the bait fish, so you have to put the bait into the sea, drop the sachet and manipulate the sachet to synchronize with the bait . However, this bait does not feed the animal food to the seaweed that becomes the sassier, so it is completely opposite to the conventional fishing method that throws the target bait into the sea and attracts the target fish. It is an efficient fishing bait fishing method that makes it possible to catch the target fish without fired bait.

3. Simply attaching animal food or conventional seaweed to the fishhook will reduce the weight of the fish, so it will tend to entangle Harris in the seawater when dropped, but in the present invention, the substance itself that becomes the core to which seaweed is attached Due to its weight, Harris is less likely to get entangled and can be quickly sunk to the tana without attaching a weight. In addition, the present invention can change the weight of the core material, controls the speed of sinking in seawater, and does not fall to the target tana according to the conventional weight, but mainly the core Since the substance and the bait itself sink, it becomes possible to reach the target tana earlier than the conventional fishing method. Therefore, the response to the depth of the tana appears faster and more accurately. In other words, in the conventional method, it is difficult to confirm whether the tana is accurate because the target fish is more likely to bite before reaching the target tana than the fishing method using this seaweed bait. The bait reaches the target Tana early, and it is easy to confirm the reaction of whether the Tana depth is appropriate.

4). Since the core substance with seaweed attached is heavy, it is easy to create a tension on Harris without using a newt, and it makes it difficult for the target fish to feel uncomfortable. I can do it. In addition, the target fish is likely to eat the prey of Harris, but in order to create that state, it is necessary to wait until Sashe reaches the bottom. Because of this, it is difficult to reach that state. However, in the present invention, since the core substance itself is heavy, it is easy to create a state in which Harris is stretched out, and the probability that the bait will be eaten increases.

5. The traditional fishing method is that the target fish derived from a mixture of several hundred to several thousand cut krills and mixed feeds is a flat krill with a size of about 5-10 mm. This is a fishing method with a low probability of scouring. However, the present invention feeds on seaweed that is supposed to be an original food, and the seaweed attached to the nucleus spreads three-dimensionally so as to hide the fishing hook in the seawater, and is high when viewed from the side, front, and bottom of the target fish. Since it enters the field of view with probability (see FIGS. 4 to 6), it becomes easy to eat food. It is also effective for target fish that are squeezed into krill and mixed feed.

Examples of the present invention are shown in detail below, but the present invention is not limited thereto.

(1) Preparation of culture solution The culture solution was obtained by adding trace metals to nitrogen, phosphorus, and potassium in seawater collected and filtered. The collected seawater was adjusted to a specific gravity of 1.020 or more, left in a dark place for 3 days, filtered through 10 μm and 1 μm, then filtered through a 0.22-0.45 μm filter, sterilized, and sterilized by autoclaving. . The culture solution was prepared by adding 20 ml of the following nutritional supplement to 1000 ml of filtered and sterilized seawater.
Nutritional supplement:
Pure water 60ml, NaNO ₃ 350mg, sodium glycerophosphate 50mg, Fe (Mixed with EDTA 1: 1 mole) 2.5mg, PII metal mixture 25ml, vitamin B ₁₂ 0.01mg, thiamine 0.5mg, biotin 0.005mg,
500 mg of tris was added to adjust the pH to 7.8-8.0, and then pure water was added to make a total of 100 ml.
PII metal mixture (100ml):
It was prepared from Na ₂ EDTA 100 mg, FeCl ₃ · 6H ₂ O 5 mg, H ₃ BO ₃ 100 mg, MnCl ₂ · 4H ₂ O 14 mg, ZnCl ₂ 1 mg, CoCl ₂ · 6H ₂ O 0.4 mg.

(2) Next, the clean leaves of Susabinori that had been cultured at 15 ° C were transferred into a culture solution at a temperature of 25 ° C in a 300 ml Erlenmeyer flask. The spore spores were released up to / ml, and a spore spore solution cooled to 18 ° C. was prepared. The core material is a glass bead (8mm square, 0.8g) with a hole through which a fishhook can pass, and the hole in the bead is filled with rubber to increase adhesion of shell spores. After the surface was washed with double distilled water, it was acclimatized by immersing in the same solution as the culture solution for 2 days. In order to prevent the glass from overlapping, a small bead (2 mm), which had been cleaned in advance and treated in the same manner as the core bead, was sandwiched between beads to which seaweed was attached, and a fishing line was passed through. In order to attach as much of the spore as possible to the glass, hang it horizontally in the spore solution, immerse the core substance in the spore solution carefully for 3 hours, and gently stir the spore solution. However, the adhesion and germination of shell spores were increased by attaching more to the upper surface of the glass than the other surfaces.

(3) The shell spores attached to the glass were cultured at a water temperature of 18 ° C. Irradiation was performed for 10 hours a day with 3000 lux lighting, and the remaining 14 hours were not irradiated. Aeration agitation was performed at 6 liters per minute by aeration once passed through another culture solution to prevent drying. The culture solution was replaced with a fresh one every 4 days to supply nutrients and proliferate, and cultured for about 3 to 4 weeks. The core beads were taken out when the length of the frond body reached 1 cm or more, and used as food for saltwater fish. The fronds that grew beyond the length of the fishhook were cut at the top of the fronds or rolled to the desired size with thread.
(4) One or several of the above fishing baits are arranged in the predetermined position of the fishhook shown in FIG. 1 and fished by an omnivorous or vegetative marine fish through the hole in the feed as shown in FIGS. Was made.

  From the structure of the seaweed bait of the present invention, 1. 1. Desorption is not time-consuming and difficult to come off. 2. It is possible to avoid feeding prey of animal food and to reach the target target fish tana. Harris is not easily entangled by the weight of the changeable core material itself, and it can be quickly submerged to tana without attaching a weight. This also makes it difficult for the target fish to have a sense of incongruity due to the tension of Harris. The bait is a seaweed that is supposed to be an original food, and the seaweed spreads in a three-dimensional manner so as to hide the fishhook in the seawater, and has an advantage that it is easy to catch a fish because it enters the field of view with a high probability in the target fish. Therefore, the seaweed bait for omnivorous marine fish or phytophagous marine fish of the present invention is useful in fishing for omnivorous marine fish or vegetarian marine fish.

The side view of the fishing hook used by this invention is shown. The perspective view of the bead used by this invention is shown. The figure which connected the bead used as a nucleus in order to attach a shell spore is shown. Fig. 2 shows a sasabinori which is one of the feeds of the present invention. The side view which let the feed and krill of this invention pass the fishing hook is shown. The front view which let the bait and krill of this invention pass the fishing hook is shown. The bottom view which let the feed and krill of this invention pass the fishing hook is shown.
