Description

本考案は牡蠣の養殖に用いられる付着器に関し、より詳しくは牡蠣の幼生を付着させ生育させるために用いられる付着器に関する。   The present invention relates to an applicator used for oyster culture, and more particularly to an applicator used to attach and grow oyster larvae.

夏、卵からかえった牡蠣の幼生は、約2週間、浮遊生活を送り、その後、海水中の固着物に付着する。この時期に、帆立貝の貝殻にワイヤーを通して一定間隔で取り付けた採苗連を海中に入れておき、牡蠣幼生(約0.3ミリメートル)を付着させる。この作業を採苗という。この際、図6に示すように、貝殻1同士の間隔を一定に保つため、樹脂製のパイプをスペーサ2aとして貝殻一枚ごとにワイヤー3aに通す作業が行われる。なお、図6においては可視的にするため、スペーサ2aと貝殻1との間に距離を設けてあるが、実際には貝殻1・・とスペーサ2a・・とは密着するものである。   In summer, oyster larvae turned from eggs live a floating life for about two weeks, and then adhere to the solid matter in the seawater. At this time, a collection of seedlings attached to the scallop shell at regular intervals through a wire is placed in the sea, and oyster larvae (about 0.3 mm) are attached. This operation is called seedling. At this time, as shown in FIG. 6, in order to keep the interval between the shells 1 constant, an operation of passing a resin pipe as a spacer 2a through the wire 3a for each shell is performed. In FIG. 6, a distance is provided between the spacer 2a and the shell 1 to make it visible, but the shells 1 ·· and the spacers 2a ·· are actually in close contact with each other.

一つの採苗連には貝殻70枚前後が取り付けられており、上下の長さは1メートル程度になる。   One seedling series has around 70 shells attached, and the vertical length is about 1 meter.

採苗した牡蠣の幼生は、採苗連のまま沿岸の棚(抑制棚)に移動させる。抑制棚は、干潮の時より高い位置にあるため、採苗連は水中につかっている時間が少なくなるとともに、日光や風波にさらされることになる。係る工程は、牡蠣を大きくしないため(大きくなりすぎると翌年の夏の産卵後に死ぬことが多い)と、環境の変化に強い抵抗力を付けさせるために行われる。抑制棚に吊るされている期間は3〜6ヶ月程度である。   The collected oyster larvae are moved to the coastal shelves (restraint shelves) in the same manner as the seedling series. Since the restraint shelf is higher than at low tide, the seedling reams will spend less time in the water and will be exposed to sunlight and wind waves. Such a process is performed in order to prevent the oysters from becoming large (when they become too large, they often die after the egg laying in the summer of the following year) and to give strong resistance to environmental changes. The period suspended on the restraint shelf is about 3 to 6 months.

次いで、図7に示すように採苗連からホタテ貝の貝殻1をはずして、新しいワイヤー3bに1枚ずつ移し替えて垂下連を作成する。このことを通し替え作業という。一本のワイヤー3bに、6〜9枚程度の牡蠣の稚貝が付着した貝殻1を、30センチ程度の間隔を開けて通す。係る間隔を維持するために、樹脂製のパイプをスペーサ2bとして貝殻一枚ごとに、ワイヤー3bに通す作業が行われる。なお、図7においては可視的にするため、スペーサ2bと貝殻1との間に距離を設けてあるが、実際には貝殻1・・とスペーサ2b・・とは密着するものである。   Next, as shown in FIG. 7, the scallop shell 1 is removed from the seedling series, and transferred to a new wire 3b one by one to create a drooping series. This is called reworking. The shell 1 to which about 6 to 9 oysters are attached is passed through one wire 3b with an interval of about 30 cm. In order to maintain such an interval, an operation of passing a resin pipe as a spacer 2b and passing through the wire 3b for each shell. In FIG. 7, a distance is provided between the spacer 2b and the shell 1 to make it visible, but the shell 1 ·· and the spacer 2b ·· are actually in close contact with each other.

かようにして作成された垂下連は、筏に吊し、1つの筏に約600本が吊される。1本の垂下連の長さは、筏の海底までの距離により異なる。   The drooping series created in this way is hung on a cage, and about 600 are suspended on one cage. The length of one droop depends on the distance to the seabed.

かようにして垂下してから収穫するまでの期間は、短い期間の養殖方法(イキス養殖)でも12〜13ヶ月を要する。その間、牡蠣が死なないように、また、有害な生物が付着しないようにし、そして身が良く入るように様々な工夫がなされる。   Thus, the period from drooping to harvesting requires 12 to 13 months even with a short-term culture method (Ichs culture). In the meantime, various measures are taken to prevent the oysters from dying, to prevent harmful organisms from attaching, and to get in well.

上述のように、牡蠣を付着させるための付着器として一般的に貝殻が利用される。   As described above, a shell is generally used as an applicator for attaching oysters.

そして、貝殻に代わる牡蠣養殖用付着器として、円板トレーの上面に凹凸を付け、更に積み重ねた円板トレーの回りにメッシュカーテンを施したもの(特開昭49−131892)や、円板トレー表面にカルシウムを付着させたもの(特開昭50−142393)が提案されている。   Further, as an oyster culture adhering device to replace shells, a disc tray is provided with irregularities on its upper surface, and a mesh curtain is provided around the stacked disc trays (Japanese Patent Laid-Open No. 49-131892). One having calcium attached to the surface (Japanese Patent Laid-Open No. 50-142393) has been proposed.

特開昭49−131892号公報JP 49-131892 A 特開昭50−142393号公報JP 50-142393 A

前記のように採苗連を作成するためには、貝殻一つ一つに穴を開け、ワイヤーを通し、一枚毎にスペーサを介在させるという作業が必要となる。更には垂下連を作成する際にも、採苗連から貝殻をはずして、新しいワイヤーに1枚ずつスペーサを介在させながら移し替える作業が必要となる。これら作業は手作業で行われており、非常に手間がかかるものである。   In order to create a seedling series as described above, it is necessary to make a hole in each shell, pass a wire, and interpose a spacer for each sheet. Furthermore, when creating a drooping series, it is necessary to remove the shells from the seedling series and transfer them one by one with a spacer on each new wire. These operations are performed manually and are very time-consuming.

そこで、本考案はかかる作業を大幅に簡略化させることが可能な、牡蠣養殖用付着器を提供することを目的とする。   Therefore, an object of the present invention is to provide an applicator for oyster culture that can greatly simplify such work.

上記の目的を達成する本考案の構成は次の通りである。   The configuration of the present invention for achieving the above object is as follows.

(1) 請求項1に記載の牡蠣養殖用付着器は、支持線に複数の盤体を固着して設けた。   (1) The applicator for oyster culture according to claim 1 is provided with a plurality of discs fixed to a support wire.

(2) 請求項2に記載の牡蠣養殖用付着器は、支持線に複数の盤体を固着すると共に、盤体の中央部に突起部を設け、当該盤体及び突起部を貫通する孔部を設けた。   (2) The adhering device for oyster culture according to claim 2 fixes a plurality of discs to the support wire, and provides a projection at the center of the disc, and a hole that penetrates the disc and the projections. Was provided.

(3) 請求項3に記載の牡蠣養殖用付着器は、盤体を樹脂で形成した。   (3) The applicator for oyster culture according to claim 3 has a board made of resin.

(4) 請求項4に記載の牡蠣養殖用付着器は、樹脂に、貝殻の粉末あるいは石の粉末の一方あるいは双方を含有させた。   (4) The applicator for oyster culture according to claim 4 contains one or both of shell powder and stone powder in the resin.

(5) 請求項5に記載の牡蠣養殖用付着器は、支持線に固着する盤体と盤体との距離を15〜35センチメートルにした。   (5) In the oyster culture applicator according to claim 5, the distance between the board and the board fixed to the support wire is 15 to 35 centimeters.

本考案に係る牡蠣養殖用付着器4は、図2や図3に示されるように、盤体9の中央部に予め孔部6が設けてあるので、従来のように一つ一つ穴をあけるといった作業が不要となる。   As shown in FIG. 2 and FIG. 3, the oyster culture attachment device 4 according to the present invention has a hole portion 6 provided in advance in the center of the board body 9. Work becomes unnecessary.

牡蠣養殖用付着器4を採苗連として使用する際には、図4に示すように、この孔部6にワイヤー8等を挿通し、積み重ねて使用するものである。この際、突起部7がスペーサとしての役割を果たすので、従来のように一枚ごとにスペーサを手作業で介在させるといった手間が省けるのである。   When using the oyster culture attachment device 4 as a seedling continuation, as shown in FIG. 4, a wire 8 or the like is inserted into the hole 6 and stacked. At this time, since the projections 7 serve as spacers, it is possible to save the trouble of manually interposing the spacers one by one as in the prior art.

また、そもそも本考案の場合、採苗連の形状にしなくとも、単にドラム等に本考案に係る付着器を巻回した状態で海中に放置すれば採苗が可能であり、より容易に作業を行うことが可能なものである。したがって、請求項1に記載の考案のように、支持線5に複数の盤体9を固着したもので、十分用途を果たすことが可能となるのである。   In the first place, in the case of the present invention, it is possible to collect seedlings by simply leaving them in the sea with the applicator according to the present invention wound around a drum, etc. Is something that can be done. Therefore, as in the idea of the first aspect, a plurality of disk bodies 9 are fixed to the support wire 5, so that sufficient use can be achieved.

牡蠣養殖用付着器4を垂下連として使用している状態を示すのが図5である。採苗連の状態からワイヤー8を抜けば、牡蠣養殖用付着器4は支持線5に固着されていることから、自動的に垂下連となるのである。すなわち、従来のように、スペーサを一枚ごとに手作業で介在させるといった手間が省けるのである。   FIG. 5 shows a state in which the oyster culture applicator 4 is used as a drooping series. If the wire 8 is removed from the state of the seedling continuation, the oyster culture adhering device 4 is fixed to the support wire 5 and thus automatically becomes a drooping series. That is, as in the prior art, the labor of manually interposing the spacers one by one can be saved.

盤体9同士は一般的な垂下連と同様に15〜35センチメートル程度の間隔を採ることが好ましい。   It is preferable that the board bodies 9 have an interval of about 15 to 35 centimeters similarly to a general drooping series.

請求項4記載の考案においては、盤体を形成する樹脂に貝殻の粉末や石の粉末が混入されている。これにより牡蠣の幼生の付着を促進させ、あるいは幼生の脱落を減らすことが可能となるのである。   In the invention according to claim 4, shell powder and stone powder are mixed in the resin forming the board. As a result, adhesion of oyster larvae can be promoted, or dropout of larvae can be reduced.

以下、好ましい考案の実施形態を概説する。   The preferred embodiments of the invention are outlined below.

牡蠣養殖用付着器4は、盤体4を支持線5に固着して形成されるものである。固着する方法としては、例えば樹脂を押出成形し、固化する前に支持線5に溶着するといった手段が採用可能である。請求項3記載の考案においては、樹脂に貝殻の粉末や石の粉末を混入して押出成形してある。   The oyster culture applicator 4 is formed by fixing the board 4 to the support wire 5. As a method of fixing, for example, a method of extruding a resin and welding it to the support wire 5 before solidification can be employed. In the invention according to claim 3, shell resin powder or stone powder is mixed into the resin and extruded.

紐体たる支持線5はロープやベルト、ワイアーなどを利用可能であるが、垂下連として耐えうる強度を要するものである。   A rope, belt, wire, or the like can be used as the support wire 5 as a string, but it needs to have enough strength to withstand as a droop.

盤体4の形状は、図1乃至図5においては円盤状であるが、係る限定を受けるものではなく、方形の盤体や貝殻類似形状の盤体等、牡蠣が付着可能な形状であれば任意の形状を採用可能である。   The shape of the disc body 4 is a disc shape in FIGS. 1 to 5, but is not limited thereto, and any shape such as a square disc or a shell similar to a shell can be attached. Any shape can be employed.

請求項2に記載の考案においては、盤体4の中央部に円筒形状の突起部7が一体形成してあり、突起部7及び盤体9を貫通する孔部6が設けてある。   In the second aspect of the invention, a cylindrical projection 7 is integrally formed at the center of the board 4, and a hole 6 that penetrates the projection 7 and the board 9 is provided.
