Description

  The present invention relates to a scallop shell that locks and supports a scallop shellfish with a predetermined span via a locking device, and suspends the rope into the sea, promotes the scallop growth in the sea, and cultivates the scallop shell. In aquaculture, when landing scallops that have grown by pulling a rope from the sea after a while, the scallops are prevented from breaking due to increased weight due to the attachment of miscellaneous substances and the scallops falling due to this. It is about the method.

The locking pins are penetrated and held at a predetermined interval in the direction perpendicular to the length of the rope, and the scallop (fry) shell ear pieces are locked to the retaining portions at both ends of the locking pin, and the rope is suspended in the sea. However, a scallop culture method for cultivating scallops has been conventionally performed.
A locking pin used for such scallop cultivation is conventionally known.

Japanese Patent No. 3375506

15-19 is explanatory drawing of the scallop culture method.
As shown in FIG. 15, the locking pins 101... (... indicate a plurality. The same applies hereinafter) are passed through the rope 100 at predetermined intervals, and the larvae of the scallops 102 are provided at both ends of the locking pins 101. A piece is locked, and after dredging, this rope is suspended in the sea for aquaculture.
The rope 100 has a diameter of 6 to 8 mm, a length of 10 to 15 m, and a locking pin having a length of 7 to 8 cm is passed through and held in a direction perpendicular to the length direction of the rope at a pitch of 10 to 13 cm, The ear piece of the scallop 102 is locked and held at both ends of each locking pin.

FIG. 16 is an explanatory view showing a cultured state of scallops.
A horizontal rope 104 having both ends bound to the anchor ropes 103, 103 is horizontally bridged, and the horizontal rope 104 is spaced in the length direction (lateral direction) to bind the upper ends of the plurality of ropes 100, This rope 100 is hung in the sea in parallel.
A plurality of sets of scallops 102 are held and held on each rope 100 by a locking pin at a predetermined pitch in the length direction.

The horizontal rope 104 is bundled with a plurality of floats 105 at predetermined intervals, the horizontal rope 104 is held at a predetermined depth below the sea surface, and the float 106 is formed at both ends of the horizontal rope 104 and the binding sites of the anchor ropes 103 and 103. 106, and the floats 106 and 106 are exposed on the sea surface, and the presence of the floats 106 and 106 is used as a mark for a culture location on the sea surface.
In this way, scallops are cultivated by dripping and invading juveniles of scallops vertically through the rope.
The culture period is 10 to 12 months.

By the way, as shown in FIG. 16, scallops held by a rope with a locking tool are cultivated in a state where they are suspended and held in the sea via a rope, but a large amount of deposits ( Grown scallops and miscellaneous materials) adhere.
That is, as shown in FIG. 17, miscellaneous matters 107 such as mussels, barnacles, and sea squirts adhere to the rope 100 and scallops 102 over time.
The miscellaneous material grows with time, and the rope including the scallops may become thick like a telegraph pole depending on the adhered miscellaneous material 107, and the thickness may reach about 30 cm to 40 cm.

FIG. 18 is an explanatory view showing a landing state of a scallop.
The rope 100 is wound up by the hoisting machine 109 and the hoisting guide 110 disposed on the shore side 108 a of the ship 108, and the scallops 102 locked and held on the rope 100 by the locking tool 101 are landed. At the time of landing, the miscellaneous matter 107 attached to the scallop 102 and the rope 100 is also lifted together.

By the way, a large amount of deposits attached to the rope and the grown scallop are heavy.
At the time of landing, when the rope is pulled up on the sea surface, unlike the underwater, the grown scallops and the adhered matter composed of the attached foreign matter lose buoyancy.
As a result, the deposits (grown scallops and a large amount of adhering matter) pulled up on the sea surface due to the load of the deposits lose their buoyancy by being exposed from the sea surface. Since its own weight is large, the adhering matter breaks the locking tool 101 itself holding it on the rope by its weight, and the adhering matter falls vertically along the rope.
This state is shown in FIG.

By the way, the fall of the deposit that starts on this sea level faces the lower deposit, and touches or touches it, and the weight of the fallen deposit acts on the lower deposit, as if avalanche. So that it propagates to the lower deposits.
Thereby, the lower deposits in the water held by the rope are triggered by the fall of the upper deposits, and the fall and drop are induced in a daisy chain.
As a result, a large amount of scallops cultured and grown can be lost.

By the way, suspended objects close to the sea surface, especially suspended objects placed 2m to 3m from the sea surface, are affected by the up and down movement of the waves and support the scallops arranged near the upper end of the rope. Since the scallops that are locked are alternately shaken by the waves, the tool is weak in strength and easily broken.
Therefore, it breaks the initial locking tool at the time of landing as described above, the fall of deposits including scallops, and the avalanche phenomenon, causing a large loss of scallops after growth.
By the way, since the drooping object below is less affected by the wave, the deposits including the scallops are hardly shaken, the posture is stably maintained in the sea, and the locking tool is not weak.
By the way, the scallops after growth and the rope with the hanging objects including the miscellaneous objects, including the miscellaneous objects, reach a diameter of 20 to 30 cm, and the length is 15 m. It reaches 1 ton.

  The present invention was made to prevent the occurrence of scallops (scallops, deposits made of miscellaneous material) falling when landing scallops after aquaculture, and the occurrence of avalanche-like ross-like fall caused by this. It was made by paying attention to the fact that the fall of the upper deposit starting on the sea surface propagates to the drooping object at the bottom like an avalanche phenomenon when landing.

The object of the present invention is to drop the deposits (the grown scallops and other impurities attached thereto) generated during the landing of the grown scallops in aquaculture, and the avalanche phenomenon scallops resulting therefrom Prevent the fall of the.
This significantly improves the efficiency of landing scallops in scallop farming, significantly increases the recovery efficiency of cultured scallops, and can improve the landing efficiency and recovery efficiency of scallops by a simple method. Provide prevention methods.

  In order to solve the above-mentioned problems, the invention according to claim 1 is configured such that a locking tool is locked to a rope, and scallops are locked to both ends of the locking tool and suspended to form a unit of scallop culture unit. In this scallop culture unit, a unit of scallop culture unit is locked at a predetermined interval in the length direction of the unit rope, and the rope is suspended in the sea to culture the scallop shell. A receiving member extending radially outward of the rope is attached to the lower side of the upper scallop farming unit near the sea surface, and when the scallop is grown after landing, the upper scallop farming unit exposed from the sea surface is dropped from the rope. It is characterized in that it is received by the receiving member.

  When the rope is lifted at the time of landing, the upper hanging objects exposed from the sea (scallops after growing and miscellaneous matters such as mussels, barnacles, and sea squirts attached to the rope) will break and fall due to their own weight. Even if it is received by the receiving member attached to the lower side, the dropped drooping object does not touch or overlap the lower hanging object.

  According to a second aspect of the present invention, in the first aspect, the scallop culture unit close to the sea surface is one unit or a plurality of units at an upper portion of the rope that is easily affected by vertical movement caused by sea surface waves. The receiving member is attached to the lower side of the unit cultured scallop unit.

  One unit or a plurality of scallop farming units at the top of the rope, which are easily affected by vertical movements caused by sea surface waves, are weakly locked and easily broken when landing. By providing the receiving member on the lower side of the scallop farming unit, it is possible to prevent the scallop farming unit including the deposits that are most easily broken and easily dropped from being dropped on the lower scallop farming unit.

  According to a third aspect of the present invention, in the first or second aspect, the receiving member is a peg that is penetrated and held in an I-shape / ten-shape by the rope as viewed from the cross section thereof, or a funnel attached to the rope. It is a shaped member.

  Since the peg is attached to the rope in the shape of I / ten, or the funnel-like member is attached to the rope, it is possible to obtain an effective drop prevention effect when landing the cultured scallop with simple methods and simple members. .

In the invention according to claim 1, when the rope is pulled up at the time of landing, the upper scallop culture unit exposed from the sea (hanging scallops after growth and suspended objects including miscellaneous matters such as mussels, barnacles, and sea squirts attached to the rope) Even if the buoyancy is lost and the locking tool is broken by its own weight and dropped, the scallop culture unit can be received by the receiving member.
This prevents the lower scallop culture unit from being touched or placed on the lower scallop culture unit, which falls when the locking device breaks, and the lower scallop culture unit resulting from the fall of the upper scallop culture unit. It can prevent the avalanche phenomenon of rosary-connected fall that has an influence on the aquaculture unit and triggered by the fall.

Therefore, it is possible to prevent the occurrence of scallop loss during landing as much as possible, and to efficiently land and collect cultured scallops.
And since it can be achieved just by attaching a receiving member via the rope to the lower side of the upper part of the scallop farming unit that hangs the above on the rope, the simple method and simple member can be used for effective scallop landing. Fall prevention can be realized.

In the invention according to claim 2, the locking tool is weak in one unit or a plurality of units of the scallop culture unit at the upper part of the rope which is easily affected by the vertical movement due to the sea surface waves. Therefore, this locking tool is easily broken when landing.
By providing the receiving member on the lower side of the scallop culturing unit that is likely to fall, it is possible to prevent the influence of the drop to the lower part of the scallop culturing unit that is most easily broken and includes deposits that easily fall.
Therefore, the avalanche phenomenon of falling to the lower scallop farming unit due to the fall of the upper scallop farming unit close to the sea surface can be prevented, and the occurrence of scallop loss during landing is prevented as much as possible. It is possible to land and collect well-cultured scallops.

  In the invention according to claim 3, simply attaching a peg or a funnel-shaped member to the rope, so that the peg is penetrated and locked, and the funnel-shaped member is fixed so as to surround the rope, and With a simple member such as a peg or a funnel-shaped member, it is possible to obtain an effective drop-off preventing effect when the cultured scallop is landed.

As shown in the figure, the upper end 1 a of the rope 1 is supported in a vertically suspended manner via a binding tool 9 on a horizontal rope 3 that floats and extends horizontally (substantially horizontal) below the sea surface.
Locking pins 4 (locking tools) are locked and held in the rope 1 so as to penetrate and cross the rope. Ear pieces 5a of scallops 5 pass through both ends of the locking pin 4, That it is stopped and held is the same as described above.

One unit of the scallop culture unit 6 is constituted by the locking pin 4 and the scallops 5 and 5 held and held at both ends thereof.
In FIG. 4, the highest scallop farming unit 6 is A, the second scallop farming unit 6 is B, the third scallop farming unit 6 is C, and the fourth scallop farming unit 6 is D. , Hereinafter referred to as E ~.
The space | interval of the rope length direction between each unit A, B, C, D- is 10-13 cm. A number of scallop farming units are locked and held by ropes from the top to the bottom at a pitch of 10 to 13 cm, and scallops are cultured by invading into the sea.
A weight 8 is attached to the lower end of the rope to fix the rope on the sea floor.

In the above, among the scallop farming units A˜ locked and held on the rope 1, it is close to the sea surface and is susceptible to wave up-and-down movement, from the uppermost to the lower one, for example, the rope 1 in the embodiment. The above-mentioned pegs 2 and 2 are pushed into a “cross-shape” to be fixed and supported between the stopped and held second scallop farming unit B and the third scallop farming unit C. Member 7 is formed.
The pegs 2 and 2 are fixed and supported in a “cross shape” on the rope 1, and the second scallop culture unit B of the upper scallop culture unit faces the receiving member 7, and the scallop culture unit The topmost scallop farming unit A is on B.

By the way, in the embodiment, under the third scallop culture unit C of the rope 1 and above the fourth scallop culture unit D, that is, the third scallop culture unit C and the fourth scallop culture unit D. Similarly, between the aquaculture unit D, the above-described pegs 2 and 2 were pushed into a “cross shape” and fixed and supported as a receiving member 7.
Therefore, in the embodiment, the “cross-shaped” receiving members 7 and 7 are arranged vertically in two stages, and the receiving members 7... May be arranged in two or more stages. But it ’s okay.
In this way, among the upper parts of the multi-stage scallop farming unit suspended and held on the rope, it is easily affected by waves, the locking pin is likely to break when landing, and if it falls, the lower part may be affected. The receiving member 7 is disposed immediately below a certain upper scallop farming unit.
This state is shown in FIG.

At this time, the scallop farming unit 6 including the miscellaneous matter 10 in a portion close to the sea surface, that is, for example, the above-described A to C increases in weight due to adhering matter, and is lifted from the sea surface and loses buoyancy. Due to its large size, the deposit and the deposit including the scallop culture unit break the locking tool itself by its weight, and the deposit is detached from the rope and falls off.

By the way, the upper scallop farming units that are exposed on the surface of the sea, have no buoyancy, and may be detached from the rope, and the deposits A and B including miscellaneous substances are detached from the rope when the locking device breaks. In this case, the receiving member 7 composed of the “cross-shaped” pegs 2 and 2 is attached immediately below, so that it can be received.
Accordingly, the load of the attached and dropped adhering material is supported by the lower receiving member 7, and the adhering material C immediately below is also supported by the receiving member 7 in the embodiment.

Accordingly, the adhering material (scallop farming unit, miscellaneous matter) is detached from the rope and dropped and supported by the receiving member 7. Prevent breakage and detachment from the rope.
Secondary, even if the latching tool breaks and the attached matter is detached, the attached matter is supported by the receiving member 7 from below, and even if the attached matter falls from the rope, the receiving member 7 causes the rope to Prevent fall along.

As a result, when the rope is lifted, the upper deposit (scallop farming unit, miscellaneous matter) A, B, or the lower deposit due to separation from the rope such as C (scallop farming unit, miscellaneous) Can be prevented.
In this way, it is possible to prevent drooping (scallop culture unit, miscellaneous matter) falling on the sea surface when landing and avalanche phenomenon caused by this, and the recovery efficiency of scallops grown and grown is dramatically improved. improves.
