Description

  TECHNICAL FIELD The present invention relates to a shellfish culture cultivar, and more particularly to a structure of an opening for taking shellfish in and out of a substantially quadrangular pyramid cultivar called a soup bowl.

  Among the cultivated culms, in the ridged culm, one of the four inclined ridges of the substantially quadrangular pyramid is an opening that is not stitched.

  In general, as shown in FIG. 9 (a), both edges of the opening 101a of the cultivating rod 101 are joined in parallel on the left and right sides so that the shell does not escape. The binding string 101b is used for binding.

  Further, regarding the structure of the opening, the upper and lower polymerization structure shown in FIG. 9B is also well known. This upper and lower superposed structure extends both edges of the opening 102a of the culture rod 102 so as to overlap each other, and the shells do not escape from the opening 102a due to the overlapping of the upper and lower extensions. The cultured trough employing this upper and lower polymerization structure is also shown in Patent Documents 1 and 2 below.

  By the way, as one of the methods for cultivating mobile edible shellfish such as scallops, a plurality of larvae are accommodated in one aquaculture cage until a certain size and hung in the sea. There is a way to protect against natural enemies such as starfish and octopus, as well as preventing shells from escaping. Then, after raising the larvae that have been accommodated until they reach a certain size, transfer them to a different culture cage that matches the size, and repeat the procedure for further growth until they become adults. Yes.

Such transfer work is performed after a large number of workers per person are handled and a large number of aquaculture rods are lifted to the land, so processing in a short time is required to maintain freshness. And need to be done intensively in a short time.
Japanese Patent No. 3222107 Japanese Patent No. 3527428

  The above transfer operation is performed by turning the aquaculture rod upside down, opening an opening, and dropping shellfish into a bucket or the like. However, with the structure of FIG. 9A, it is necessary to pull out the binding string 101b from the opening 101a, and after inserting the shellfish, it is necessary to bind the binding string 101b, which is inefficient. There are problems.

  9 (b), when the culture rod 102 is turned downward, the opening 102a is not completely opened, and the both sides are greatly overlapped and narrowed. Inefficiency is inevitable.

  Accordingly, the present invention is to solve the above problems, and an object of the present invention is to provide a shellfish cultivating rod that can be transferred quickly and with high yield without generating residual shellfish by a simple shaking operation. To do.

  In order to achieve the above-mentioned object, as shown in the first embodiment of FIGS. 1 to 4, the present invention provides a net 3 in which a bottom surface and an upper outer periphery of a frame 2 framed in a substantially square shape are surrounded in a substantially quadrangular pyramid shape. And at least one of the four ridges of the substantially quadrangular pyramid in the net 3 has a non-stitched opening 8 and is substantially parallel to the left and right opening edges of the opening 8 in the outward direction. It is characterized in that an edge portion 6 protruding upward is formed.

  The edge portion 6 is composed of left and right edge pieces 6 ′ and 6 ′ composed of continuous portions of the net 3 that continue outward from the left and right opening edges of the opening 8, and the left and right edge pieces 6 ′ and 6 ′. The both edges of the raised edge are closed, and the opening 8 is formed between the longitudinal directions of the left and right edge pieces 6 ', 6' formed. In the first embodiment, the lower edge portions of the edge pieces 6 ′ and 6 ′ are closed by bending the net, and the upper edge portion is closed by adhesion between the edge pieces 6 ′ and 6 ′.

  In the above configuration, when shells are taken out from the cultured cage, by opening the cage upside down, the opening 8 between the edge portions 6 opens naturally, and the shellfish falls and is taken out. At this time, the edge portion 6 Becomes a funnel-shaped guide for removing shells, and shells fall smoothly and are removed.

  The edge portion 6 can be folded inside the ridge.

  Such folding prevents the shellfish from escaping or being thrown into the sea during the period when the shark is suspended and cultured in the sea.

  Further, in the present invention, as shown in the second embodiment of FIGS. 5 to 8, a net 3 is provided that surrounds the bottom part and the upper outer periphery of the frame 2 framed in a substantially square shape in a substantially quadrangular pyramid shape. 3, in which at least one of the four ridge lines of the quadrangular pyramid has a non-stitched opening 8, edge portions 6 that protrude substantially parallel to the outer side are formed on the left and right opening edges of the opening 8. The opening 8 is formed between the left and right edge portions 6, and the ends are slightly inwardly of at least one of the upper and lower end edges 6 ″ and 6 ″ of the opening 8. It is characterized in that a suture site 7 is formed along the edge.

  The stitched portion 7 can be formed at a vertical position slightly along the inner edge of the upper and lower end edges of the edge portion 6.

  By forming the stitched portion 7, the rising state of the edge portion 6 is ensured, and the shells are prevented from escaping due to the discharge when the shells are taken out and the overlap of the edge portions 6 during the suspension culture in the sea. Be certain.

  The present invention is characterized in that a string member 9 is provided on the edge portion of the edge portion 6 or in the vicinity thereof in a state of extending outward or inward of the heel.

  The said string member 9 is provided in the state extended in the outward direction of the collar | bag in the both-ends edge part of the said edge part 6, or its vicinity.

  The string member 9 is formed of a single line of synthetic resin having rigidity and elasticity.

  The string member 9 can be formed by extending an extended portion of a binding string that stitches the stitched portion 7 outward of the heel.

  By the said string member 9, the opening | mouth of the opening part of the edge part outer edge of the cocoon under suspension culture can be closed. Further, when the edge portion 6 is folded or closed, the string member 9 can be used as a handle for operating the edge portion 6. It is also possible to close the mouth of the opening at the outer edge of the ridge during suspension culture by an independent string member separate from the string member 9.

  Further, in the present invention, as shown in FIG. 7b, the string member 9 is pierced through the edge portion 6 and the net 3 with at least one end of the left and right edge portions 6 folded outside the net 3, The opening 8 can be closed.

  In the present invention, in order to open the juvenile shells accommodated inside the culture trough in a bucket or the like, when the culture trough is turned upside down, the edge portion constituting the opening portion opens in a funnel shape and guides the falling shellfish In addition, the upper and lower overlapping sites do not occur at both the upper and lower ends of the opening, and the state where it is difficult for the shells to be caught by the overlapping portions is eliminated, so that quick transfer is possible. In addition, when the culture trough is suspended and grown, the left and right edges of the edge portion prevent the shell from escaping, and there is no need to bind the opening with a binding string or the like.

  Further, when the cultured salmon is suspended and grown, folding of the edge portion into the salmon can effectively prevent the shell from escaping.

    In addition, when the cultured cocoon is suspended and grown, the above string member is pierced through the edge part or both edge pieces constituting the opening part and part of the net of the cocoon body, thereby closing the opening part during growth. Is even more certain.

    When the edge portion is folded or pulled out into the bag, if the extension portion of the string member is held, the operation is easy and reliable.

  In this case, the rising polymerization of the edge portion is more reliably formed by forming a stitched portion to be sewn along the edge portion on either one of the upper and lower edge portions of the opening, preferably the upper and lower edge portions. Is done.

  In addition, when the cultured cocoon is suspended and grown, it can be opened with a simple operation by folding either one of the upper and lower end portions of the edge portion substantially parallel to the outer side of the ridge and engaging with the piercing of the string member. The part can be closed and the dissipation of the shellfish can be reliably prevented.

  By constituting the string member with a single line of flexible synthetic resin, the piercing and unloading operations are easier and more reliable.

(First embodiment)
Hereinafter, the best mode of the present invention will be described with reference to the accompanying drawings.
1 to 4 show a first embodiment of the present invention, which will be described. FIG. 1 shows an approximately quadrangular pyramid-shaped shellfish culture so-called zabu tonji to which the present invention is applied. 2a, 2b, and 2c are schematic configuration diagrams showing the production procedure of the shellfish culture trough, and Figs. 3a and 3b are schematic configuration diagrams for explaining the opening of the shellfish culture trough.

  In the figure, an aquaculture rod 1 according to the first embodiment includes a wire frame 2 made of synthetic resin such as vinyl chloride framed in a substantially square shape with corner portions R, and a bottom portion and an upper portion of the frame 2. The lower part is connected to the crossing end of the mesh 3 having a predetermined mesh shape surrounding the frame 2 and the reinforcing frame 4 arranged in a cross shape in the center of the frame 2, and the upper end is connected to the top part of the net 3. And a rope 5 for use.

  Of the four ridge line portions of the mesh 3, three ridge line portions are stitched together, and the remaining one ridge line portion is formed with a pair of rising edge portions 6 that overlap each other. The edge portions are bound by a string member 9 made of a synthetic resin filament rich in rigidity and elasticity. Further, the lower edge portions of the edge portion 6 are closed by bending the net. An opening 8 is formed between the both edge portions of the edge portion 6. When the bag is suspended, the left and right edge pieces 6 ′, 6 ′ constituting the edge portion 6 are joined to each other by tension due to their own weight when suspended, and are substantially closed.

  A rope 5 is provided through the center of the culture trough, and a loop 5a is formed at the uppermost end of the rope 5 to be attached to the aquaculture trough.

  The production procedure of the culture culvert 1 will be described with reference to FIGS. First, as shown in (a), a net 2 cut into a substantially square shape is laid on the bottom surface of the frame 2. In the unfolded shape of the net 2, the size and laying shape are set so that the diagonal position of the frame 3 is located at the center of each side of the unfolded net 2. Further, edge pieces 6 ′ and 6 ′ are formed on the net 2 so as to extend along positions corresponding to the edge portions 6.

  Next, as shown in (b), the triangular portion of the mesh 2 is raised along each side of the frame 2, and as shown in (c), stitching is performed along the adjacent positions, that is, the ridgelines of the quadrangular pyramid. 3a. At this time, the position of the edge piece 6 'is such that only the upper edge is stitched and the lower edge is folded back at both ends 6' ', 6' '. By leaving the ridge portion in a superposed state without stitching, the edge portion 6 is formed, and an opening 8 is formed between both edge portions 6 ″, 6 ″ of the edge portion 6. Next, the culture member 1 having the shape shown in FIGS. 1 and 3 is completed by connecting the string member 9 above the upper and lower edge portions of the edge portion 6 and extending it.

  As the result that the net 3 is tensioned by its own weight and the tension of the rope 5 as a result of putting the juvenile shells in the completed culture rod 1 and suspending it in the sea, a force is applied to hold the edge portions 6 in a superposed state. The part 8 will be closed naturally, and the juvenile shellfish can be safely cultivated inside the culture tub 1. As shown in FIG. 3b, the edge portion 6 is folded back and tucked into the ridge 1 to make the opening more difficult to open, which is more suitable for preventing the shell from escaping and improving the yield. . In this case, the opening of the string member 9 can be made more difficult to open by piercing the left and right edge pieces 6 ′ and 6 ′.

  If this cultured salmon is left suspended in the sea for a predetermined period of time, the larvae will grow up to a certain size in the salmon 1 by preying on plankton floating in the seawater.

  After the growth, the cultured cocoon 1 is lifted from the sea and transferred to another shore via a bucket or the like in the land. However, as shown in FIG. By expanding the gap, the juvenile shellfish is put into the bucket 10 by its own weight from the expanded opening and temporarily stored therein. In addition, when the edge part 6 is squeezed in the cage | basket, after turning back outside, a similar operation is thrown in in the bucket 10.

  At this time, the portion where the shellfish such as the overlapping portion is caught does not occur inside the bag 1, and the edge portion 6 acts like a funnel, and the whole amount of the juvenile is released into the bucket 10 through the opening. Therefore, it is not necessary to perform an excessive swinging motion or an operation for removing the larvae that have entered the gap, so that the transfer operation for each culture rod can be performed quickly and reliably.

(Second Embodiment)

The lower part is connected to the crossing end of the mesh 3 of the predetermined mesh and the reinforcing frame 4 which is arranged in a cross shape in the center of the frame 2, and the upper part is connected to the top of the quadrangular pyramid with the upper and lower sides of the ridge 1 A loop 5 a for attaching the culture rod 201 to the culture rod is formed at the uppermost end of the rope 5.

  Of the four ridge line portions of the mesh 3, three ridge line portions are stitched together, and the remaining one ridge line portion is formed with a pair of edge portions 6 that overlap each other. An opening 8 is provided. On the upper end portion and the lower end portion of the edge portion 6, a stitched portion 7 is formed that is stitched in a direction orthogonal to the longitudinal direction of the both edge portions 6 via a suture thread. An opening 8 is formed between the two suture parts 7, and the inside of the heel 1 is pushed and opened in a spindle shape at the part of the opening 8, so that juveniles can be taken in and out through the opening 8 as shown in FIG. 1. Yes.

  When the opening 8 is in the suspended state, the left and right edge pieces 6 ', 6' constituting the edge portion 6 are joined in parallel with each other by the tension force due to their own weight when suspended, and are substantially closed. ing. The upper and lower end edges 6 '', 6 '' of the edge pieces 6 ', 6' are closed, and the stitched portion 7 is formed substantially parallel to the both end edges at a slightly inward position.

  Furthermore, one end of a filament-like string member 9 made of a synthetic resin material rich in rigidity and elasticity is bound to the upper and lower stitched portions 7. As shown in FIG. 7B, the string member 9 is pierced in a zigzag manner between the meshes on one side of the both edge portions 6 so that the edge portions 6 are brought into close contact with each other by its rigidity, and the mesh 3 is folded back. And the opening 8 is maintained in a closed state.

  The production procedure of the aquaculture rod 201 will be described with reference to FIGS. First, as shown to (a), the net | network 3 cut | disconnected by the substantially square is spread | laid, and the flame | frame 2 is installed in the upper part. In the unfolded shape of the net 3, the size and laying shape are set so that the diagonal line position of the frame 2 is located at the center of each side of the unfolded net 3. Further, an edge piece 6 ′ is formed on the net 3 so as to extend along a position corresponding to the edge portion 6.

  Next, as shown in (b), the triangular portion of the net 3 is raised along each side of the frame 2 and, as shown in (c), adjacent positions, that is, along the ridges of the quadrangular pyramids. Suture 3a along At this time, the edge piece 6 'is formed in the edge portion 6 by standing up in a superposed state without stitching. Of the upper and lower end edges 6 ″, 6 ″ of the edge pieces 6 ′, 6 ′, the lower edge is closed by folding, and the upper edge is closed by sewing.

  Next, as shown in (d), the upper and lower end portions 6 ″, 6 ″ of the edge portion 6 are stitched with a binding thread or the like so that the upper and lower portions slightly inward of the edge portion 6 are perpendicular to the longitudinal direction. Site 7 is formed. Next, the string member 9 is tied to the upper and lower stitched portions 7, and the rope 5 (not shown) for suspending is tied between the top and the crossing end of the reinforcing frame 4, whereby FIG. 5, FIG. 6 (d) and FIG. The cultured trough 201 having the shape shown in (a) is completed.

  By putting the juvenile shellfish into the completed cultured trough 1 and suspending it in the sea, as shown in FIG. 7 (a), the net 3 is brought into a substantially polymerized state between the edge portions 6 by its own weight and the tension of the rope 5. Since the holding force is applied, the opening 8 is naturally closed and can be safely grown in a state where the larvae are confined in the culture tub 201.

  Further, as shown in FIG. 7B, by opening one side of the edge portion 6 in parallel to the outside of the mesh 3 and locking it with the string member 9, it is possible to make the opening more difficult to open.

  If the cultured salmon 201 is left suspended in the sea for a predetermined period, the larvae in the salmon 101 grow up to a certain size by preying on plankton floating in the seawater.

  After the growth, the cultured salmon 201 is lifted from the sea and transferred to another salmon via a bucket or the like on the land, but if the cultured salmon 201 is inverted as shown in FIG. The space between the parts 6 is pushed right and left, and the juveniles are put into the bucket 10 through the widened opening 8 and temporarily stored therein. In addition, when the edge part 6 is folded back to the outer side, after turning back outside, the fry is put into the bucket 10 by the same operation. Moreover, even if the string member 9 is entangled, the string member 9 is naturally displaced by its own weight, so that the string member 9 is not required to be removed when the juvenile is released.
