この発明は、ホタテ貝を海水内に繋ぎ止めて養殖を行う
ホタテ貝の養殖方法に係り、特に、ホタテ貝の防止手段
の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for cultivating scallops by tethering them in seawater, and particularly to improvements in means for preventing scallops.
従来、ホタテ貝の養殖方法には、ホタテ貝の耳を以て繋
ぎ止めて養殖する耳吊り養殖法がある。Conventional methods for cultivating scallops include an ear-hanging culture method in which scallops are tied together by their ears and cultured.
これは、第８図に示すように、育成した２年貝（稚貝）
程度のホタテ貝２の耳４に小孔６を開け、この小孔６に
テグス８を通して垂下用ロープ１０に一定の間隔で繋ぎ
止めて海水内に吊り下げて養殖を行う方法である。As shown in Figure 8, this is a two-year-old shellfish (juvenile shellfish) that has been grown.
In this method, a small hole 6 is made in the ear 4 of a scallop 2 of about 100 to 100 cm, and a rope 8 is passed through the small hole 6 and connected to a hanging rope 10 at a constant interval, and the scallop is suspended in seawater for aquaculture.
このような養殖方法では、ホタテ貝２の耳４に小孔６を
形成する工程が必要であり、従来、小孔６の形成は、作
業者がボール盤を以て行う方法が取られている。Such a cultivation method requires a step of forming a small hole 6 in the ear 4 of the scallop 2, and conventionally, the small hole 6 is formed by an operator using a drill press.
このような小孔６の形成を自動化しようとすると、同年
数の成育期間であっても貝の大きさが異なり、その位置
設定が困難であり、穿孔位置のずれによってホタテ貝の
生体を損傷し、死滅や奇形を生じさせるなどの不都合が
あった。このため、作業者の熟練によるところが大であ
り、自動化は困難であるとされて来たのである。If we attempt to automate the formation of such small holes 6, the size of the scallops will vary even during the same number of years of growth, making it difficult to set the position, and the deviation of the hole position may damage the living body of the scallop. , there were inconveniences such as death and deformity. For this reason, automation has been considered difficult as it largely depends on the skill of the operator.
そこで、この発明は、このような生体に損傷を加え、死
滅や奇形の発生など、ホタテ貝の成育を妨げるおそれが
ある小孔の形成に代わって、成育の妨なげにならず、防
止工程の自動化を可能にしたものである。Therefore, the present invention aims to replace the formation of small holes that may damage the living body and hinder the growth of scallops, such as death or malformation, by providing a preventive process that does not hinder the growth of scallops. This makes automation possible.

のである。The locking member straddles the hinge part 12 to form a loop shape and is bonded to the surface of the shellfish, so when the locking member is attached to the hanging member, it will be glued during its transportation or movement of the seawater 26. The peeling stress generated at the
It is possible to keep it connected for many years until the i period.
この発明のホタテ貝の養殖方法において、貝表面部に対

によって行えば、繋止部材の接着強度を高めることがで
きる。In the method for cultivating scallops of the present invention, the attachment of the locking member to the surface of the shell is achieved by using an adhesive applied to the surface of the shell.
By doing so, the adhesive strength of the locking member can be increased.
また、この発明のホタテ貝の養殖方法において、貝表面

活性化が図られ、接着強度を高めることができる。In addition, in the scallop cultivation method of the present invention, if the bonding of the locking member to the surface of the shellfish is performed after the surface of the shellfish has been pickled, the surface of the shellfish will be cleaned and activated to be effective for adhesion. It is possible to increase the adhesive strength.
第１図は、この発明のホタテ貝の養殖方法の実施例を示

図られ、短時間に十分な接着強度が得られる。B. The hinge part 12 is attached to the long side of the scallop 2 that has undergone pre-adhesion treatment with the fixing tape.
After applying an adhesive 14 such as α-cyanoacrylate adhesive 14 as shown in FIG. 1(b) to the vicinity of the curved top that straddles the area, as shown in FIG. 1(c) and (d) As shown, a prevention tape 16 such as a woven fabric tape made of flexible synthetic resin is adhered as a loop-shaped locking member. At the time of adhesion, the prevention tape 16 applies pressure to the surface of the adhesive part to harden the adhesive 14 and fix it to the long surface. When the adhesive 14 such as α-cyanoacrylate is used, in order to keep the living body of the scallop 2 in a healthy state, the adhesive is bonded and cured at an outside temperature of, for example, around 10"C, and the adhesive is cured in a short time. Sufficient adhesive strength can be obtained.
防止テープ１６の幅は、たとえば、６肛程度のものを使

布面積は、亘長面の６×１０〜１５に設定した。The width of the prevention tape 16 is, for example, about 6 holes, and the length of its fixation to the long surface is 2 to 3 times from the hinge part 12.
With a margin of 10 to 15 mm, the length of the prevention tape 16 from the non-adhesive part to the part protruding from the scallop is 1
Make it about 5 to 25 mm. In this example, the application area of the adhesive 14 was set to 6 x 10 to 15 on the long surface.
Ｃ０固定部材への固定
固定部材としてたとえば、テグスや合成樹脂製糸などの
固定糸Ｉ８を用いる。この固定糸１日に対して第１図の
（ｅ）に示すように、一定の間隔で固定する。この場合
、防止テープ１６は、固定糸１８に予め固定して置いて
もよく、貝表面に固定されたループ状を成す防止テープ
１６に固定糸１８を通して固定してもよい。As a fixing member to be fixed to the C0 fixing member, for example, a fixing thread I8 such as thread or synthetic resin thread is used. This fixed thread is fixed at regular intervals as shown in FIG. 1(e) for one day. In this case, the prevention tape 16 may be fixed to the fixed thread 18 in advance, or may be fixed by passing the fixed thread 18 through the loop-shaped prevention tape 16 fixed to the surface of the shellfish.
Ｄ、垂下用ロープへの固定

イヤラップなどの結束具２２を用いて固定し、固定糸１
８は結束具２２の固定部分にループ２４を作り、固定強
度を高める。This hanging rope 20 is fixed using a binding tool 22 such as a wire wrap as shown in FIG.
8 makes a loop 24 in the fixed part of the binding tool 22 to increase the fixing strength.
Ｅ、海水への投下
垂下用ロープ２０に防止テープ１６および固定糸１８を
介して固定されたホタテ貝２は、第１図の（ｆ）に示す
ように、海水２６内に投下して吊り下げる。この場合、
垂下用ロープ２０は、浮き２８に支持された幹縄３０に
一定の間隔で取り付ける。垂下用ロープ２０を第３図に
示すように、水平に張って固定糸１８を固定し、ホタテ
貝２を吊り下げてもよい。E. Dropping into seawater The scallop 2 fixed to the hanging rope 20 via the prevention tape 16 and the fixing thread 18 is dropped into the seawater 26 and suspended, as shown in FIG. 1(f). . in this case,
The hanging ropes 20 are attached at regular intervals to a main line 30 supported by a float 28. As shown in FIG. 3, the hanging rope 20 may be stretched horizontally to fix the fixing thread 18, and the scallop 2 may be suspended.
以上説明したＡ−Ｅの工程を経て、ホタテ貝２の固定か
ら海水２６内への投下を経て、ホタテ貝２の養殖を行う
ことができる。Through the steps A to E explained above, the scallops 2 are fixed and dropped into the seawater 26, and then the scallops 2 can be cultured.
そして、ホタテ貝２に固定した防止テープ１６は、貝表
面に蝶番部１２を跨がってループ状を成して固定されて
いるので、防止テープ１６の接着部分に対する応力集中
を避けることができ、剥離応力が小さくなる。すなわち
、接着部分に作用する応力は剪断方向となるので、防止
テープ１６の接着力は移送や潮流による応力に十分に耐
え得るのである。The prevention tape 16 fixed to the scallop 2 is fixed to the shell surface in a loop shape across the hinge part 12, so that stress concentration on the adhesive part of the prevention tape 16 can be avoided. , the peel stress becomes smaller. That is, since the stress acting on the bonded portion is in the shearing direction, the adhesive force of the prevention tape 16 can sufficiently withstand the stress caused by transportation and tidal currents.
そこで、第４図において、ホタテ貝２に対する外力をＦ

０〜９０６ となり、θ０＝４５°とすると、Ｎ。Therefore, in Fig. 4, the external force on the scallop 2 is expressed as F
, if the tension acting on the prevention tape 16 is T, the angle formed by the adhesive part is θ, and the angle formed by the prevention tape 16 is 00, then
The force NO acting in the peeling direction is as follows. Usually, for 2-year-old to adult scallops 2, θ=7
0 to 906, and if θ0=45°, then N.

の高い接着強度が得られるのである。Here, if T=F, No-0, IXF~0.2×
It becomes F. Further, as shown in FIG. 5, when the direction of force F changes, if the force acting in the peeling direction of the adhesive part of the prevention tape 16 is N, then N << NO, and the external force F
Most of it becomes shear force M. Therefore, when the prevention tape 16 is bonded in a loop across the hinge portion 12, highly reliable bonding strength can be obtained.
なお、実施例では、固定部材としては、連続した固定糸

２の成育への影響を回避できる。In addition, in the embodiment, a continuous fixing thread 18 was used as the fixing member, but as shown in FIG. 6, a short fixing thread 18
After fixing the prevention tape 16 to about two scallops 2, the fixing thread 18 may be passed through the hanging rope 20 and tied in a loop shape (or, as shown in FIG. 7, in an arrowhead shape). A small flat hole 32 with a sharp tip and through which the prevention tape 16 is passed.
At the same time, the prevention tape 16 attached to the scallop 2 is inserted into the small hole 3 using a fixture 36 provided with a return portion 34.
In that case, by fixing that part with adhesive, it is possible to avoid the influence on the growth of the scallop 2 caused by movement of the prevention tape 16.
