Description

本考案は魚類、貝類、ナマコ、ウニ、海藻などの魚介藻類を育成するための育成部と、前記育成部を支持する支持部と、方向転換具を備え、前記支持部を係留するための固定部と、前記支持部を水中に引き込むための引き込み用フロートと、前記方向転換具を介して前記支持部と前記引き込み用フロートとを連結する係留索、によって構成される養殖用水深可変係留施設に関する。   The present invention comprises a growing part for growing seafood algae such as fish, shellfish, sea cucumbers, sea urchins, seaweeds, a supporting part for supporting the growing part, a direction changer, and a fixing for mooring the supporting part. A water depth variable mooring facility for aquaculture comprising a portion, a float for pulling the support portion into the water, and a mooring line connecting the support portion and the pull float via the direction changer .

魚介藻類を育成するための養殖カゴや生簀などの収容体や、線材、紐体、貝殻などで形成された保持体などの育成部は、ロープなどで形成された支持部に取付けられて水中に設置されるが、育成部や支持部を係留する従来からの方法に「延縄式」がある。
延縄式は、水平方向に展張される支持部としての幹縄の両端に、係留用の碇綱の一端側が各々連結され、前記碇綱の他端側が水底の土俵やアンカー等の碇綱固定部に連結され、前記幹縄は主として水面付近に浮くフロート(以下水面フロートと呼称)によって表層や中層などの所要の階層に支持されている、という構成で設置される。
延縄式は、幹縄に水面フロートが一定間隔で直接取付けられて表層に設置される浮き延縄式と、幹縄に対して吊り綱が所定間隔で配設され、前記吊り綱の上端に水面フロートが取付けられ、幹縄が上層から中層付近に設置される垂下延縄式、に分類される。
浮き延縄式は、水面フロートと幹縄が水面近くに設置されるので波浪の影響を受けやすく、船舶航行に支障が生じることがあり、保全性、安全性に課題を有していた。
垂下延縄式は、ホタテやカキなどの貝類や、ナマコ、海藻などの養殖に広く普及されているもので、一定間隔で水面付近に浮く水面フロートに連結された所要長さの吊り綱に吊り下げられた支持体としての幹縄から、所要間隔で養殖カゴや線材などで形成された保持体の育成部が取付けられて水中に垂下され、幹縄の要所に調整用フロートを取付けるなどの方法で浮力を調節することにより、幹縄や育成部の深さがほぼ一定に保たれている。
垂下延縄式は前記構造に起因する課題を有しており、以下にそれを列挙する。
(1)幹縄や育成部が水面フロートを基準に設置されるため、表層の波浪や潮流などの外力が幹縄や育成部に伝わりやすく、時化によって施設の流失や破損の被害を受けやすく、育成目的生物が動揺によるストレスを受け、成長不振,病気,斃死に至ることがある。(2)育成部の水深がほぼ固定されるため、地域特性や水温変動などで適水温から外れることがあり、成長不良、病気、斃死、枯死などの事例がみられる。
(3)赤潮や降雨による淡水化が発生した時に、深さ方向の移動も、他の場所への移動もできない構造のために被害を回避することができない。
(4)水面フロート、吊り綱、幹縄が波浪による動揺や潮流による吹かれを受けて育成部の水深が変わり、深い水深階層や水底付近などに安定的に設置することが難しく、前記のような場所での育成を必要とする目的生物成育に適さず、機能性、汎用性に欠ける。
(5)表層付近に多くの部材が配設され、貝類や藻類など目的外の付着物が付きやすく、付着物による酸欠、栄養不足、成長不振、斃死、枯死が生じやすく、付着物の自重と付着物に当たる波浪や潮流による負荷が掛かり、施設の流失や破損を招きやすい。
(6)水面フロート、吊り綱が水面付近に多数存在し、操業や船舶の航行に障害となり、スクリューが絡まる事故や、乗り切り事故に遭いやすく、安全性、施設保全性に欠ける。
(7)付着物清掃作業などで育成部を引き上げる際に、育成部、育成目的生物、幹縄の自重が掛かり、碇綱の張力が加わるために負荷が大きくなり、クレーンなどの装備を要し、幹縄や碇綱が緊張するために作業に危険が伴い、作業性、省力性、安全性に欠ける。
(8)碇綱固定部の固定力確保と、幹縄や育成部引き上げ時に碇綱が張って張力が掛かる点を緩和するなどの目的で、水深の3倍前後の長さの碇綱を幹縄の両側に配設する必要があり、このため施設全体の占有面積が大きくなり、漁場の有効利用性に欠ける。
Growing parts such as cages for raising seafood algae and cages, and holders made of wire rods, strings, shells, etc. are attached to support parts made of rope etc. Although it is installed, there is a “long line type” as a conventional method for mooring a growing part and a supporting part.
In the longline type, one end side of the mooring rope is connected to both ends of the trunk rope as a support portion that is extended in the horizontal direction, and the other end side of the hoisting rope is anchored to the rope rope such as a submarine soil or an anchor. The trunk rope is installed in a configuration in which the trunk rope is supported by a required layer such as a surface layer or a middle layer mainly by a float floating in the vicinity of the water surface (hereinafter referred to as a water surface float).
The longline type is a floating longline type in which water surface floats are directly attached to the trunk rope at regular intervals and are installed on the surface layer, and suspension ropes are arranged at predetermined intervals with respect to the trunk rope, and the water surface float is placed at the upper end of the suspension rope. Is attached, and the main rope is classified into the hanging longline type, which is installed from the upper layer to the middle layer.
The floating longline type is prone to the effects of waves because the water surface float and trunk line are installed near the water surface, which may cause problems in ship navigation, and has problems in terms of maintenance and safety.
The hanging longline type is widely used for aquaculture of shellfish such as scallops and oysters, sea cucumbers, seaweeds, etc., and is hung on a suspension rope of the required length connected to a water surface float floating near the water surface at regular intervals. A method of attaching the float for adjustment to the main points of the trunk rope, attached to the trunk of the trunk rope attached to the main trunk rope as a supported support, attached with the growing part of the holding body formed with cultured baskets or wire rods at the required intervals By adjusting the buoyancy, the depth of the trunk rope and the growing part is kept almost constant.
The hanging longline type has problems due to the above structure, which are listed below.
(1) Since trunk ropes and breeding departments are installed on the basis of water surface floats, external forces such as surface waves and tides are easily transmitted to trunk trunks and breeding departments, and facilities are easily damaged or damaged by aging. The target organism may be stressed by shaking, leading to poor growth, illness, and drowning. (2) Since the water depth of the breeding section is almost fixed, it may deviate from the appropriate water temperature due to regional characteristics and water temperature fluctuations, and there are cases of poor growth, illness, drowning, and death.
(3) When desalination occurs due to red tide or rain, damage cannot be avoided due to the structure that cannot move in the depth direction or move to other places.
(4) The water surface floats, suspension lines, trunks are swung by waves and blown by tidal currents, and the depth of the breeding section changes, making it difficult to stably install in deep water depths or near the bottom of the water. It is not suitable for target organism growth that needs to be cultivated in various places, and lacks functionality and versatility.
(5) Many members are arranged near the surface layer, and it is easy to attach extraneous deposits such as shellfish and algae. Oxygen deficiency, nutrient deficiency, poor growth, drowning, and death due to deposits are likely to occur. The load of waves and tidal currents hitting the deposits is applied, and the facilities are easily lost or damaged.
(6) There are many surface floats and suspension ropes near the surface of the water, which hinders operations and ship navigation, and is prone to screw entanglements and ride-through accidents, and lacks safety and facility maintenance.
(7) When pulling up the breeding unit for cleaning the deposits, the weight of the growing unit, target organism, trunk trunk, and the tension of the ropes are added, increasing the load and requiring equipment such as a crane. Because the trunk line and the rope are tense, the work is dangerous, and the workability, labor saving and safety are lacking.
(8) Trunk a rope with a length of about three times the water depth for the purpose of securing the anchor strength of the rope rope and alleviating the point where the rope is stretched and tensioned when the trunk rope or raising part is pulled up. Since it is necessary to arrange on both sides of the rope, the occupied area of the whole facility becomes large and the effective use of the fishing ground is lacking.

これらの課題解決のために、(特許文献1)には「北海道北部日本海型浮沈延縄式養殖施設に養殖籠を垂下し、台風時等に幹縄と養殖篭を沈下させることができる浮沈延縄型沖合多段式籠養殖」が開示されている。
(特許文献2)には「養殖用生簀本体に二本のフロートを取付け、外側フロートを吸気、排気によって浮力調節を行う構造とし、空気を抜けば生簀本体が沈下し、船に積んだコンプレッサーから空気を注入することによって生簀本体が浮上する事を特徴とした、外洋で使用する浮沈式養殖生簀」が開示されている。
In order to solve these problems (Patent Document 1), “Floating and sinking ropes can be used to suspend aquaculture rods in the northern Japan Sea type floating and sinking aquaculture facility in Hokkaido and to sink trunk ropes and cultivation rods during typhoons. “Type offshore multi-stage aquaculture” is disclosed.
(Patent Document 2) states that “the structure is one in which two floats are attached to the aquaculture body, the outside float is inhaled, and the buoyancy is adjusted by exhausting the air. A “floating and sinking aquaculture ginger for use in the open ocean” characterized in that the body of the ginger rises by injecting air is disclosed.

しかしながら、上記従来の技術は、以下のような課題を有していた。
(1)(特許文献1)には、具体的な構成や方法に関して記載されていないが、図面から判断すると、通常は吊り綱に取付けた水面フロートと幹縄に取付けた調整用フロートによって幹縄と養殖籠を表層付近に設置し、所要時に吊り綱を長いものに変え、調整用フロートを取外すことによって幹縄と養殖篭を沈下させるものと推測される。しかし、このように多数の吊り綱を長いものに変える作業や、調整用フロートを取外す作業は非常に手間が掛かり、台風や低気圧に対応する時に沈下作業が間に合わないという課題があった。
(2)(特許文献2)には、養殖用生簀本体外周に内外二本のフロートを取付け、内側フロートは浮力を固定し、外側フロートにはエアーホースが連設されてフロート付きの空気弁が設けられ、空気弁からの吸気、排気で浮力調節を行う構造とし、前記生簀本体底部外枠に取付けた複数のワイヤーを海底に設置した生簀位置固定用アンカーに設置された通し金具を各々通過させ、先端に沈下用フロートを取付け、前記空気弁から外側フロートの空気を抜いて生簀本体を沈下させ、船に積んだコンプレッサーから空気弁とエアーホースを介して外側フロートに空気を注入させて、生簀本体を浮上させる事を特徴とした、外洋で使用する浮沈式養殖生簀が示されているが、次の課題を有する。
1、前記浮沈式養殖生簀は海で使用する施設としては構造が複雑で、エアーホースと給餌用パイプが水中の生簀本体から水面上のフロート付き空気弁、フロートに保持された給餌口に各々繋がれている構造で、生簀本体が浮上した時も沈下した時も、各部材及び部材間に波浪や潮流による負荷や衝撃が繰返し加わるために、ワイヤーや各部材接合部が破損するおそれがあり、耐久性に課題を有している。
2、浮上操作にコンプレッサーを要するために使用に制約を受け、台風など急を要する場合に操作が間に合わないことが想定され、複雑な構造の施設各部には貝類や海藻などの付着物が付きやすいために装置の作動不良が起こる確率が高く、汎用性、操作性、迅速性、管理性に欠けるという課題を残していた。
However, the above conventional technique has the following problems.
(1) (Patent Document 1) does not describe a specific configuration or method. However, judging from the drawings, the trunk line is usually formed by a water surface float attached to a suspension rope and an adjustment float attached to the trunk rope. It is presumed that the aquaculture culvert will be sunk by installing the cultivating trough near the surface layer, changing the suspension rope to a long one when necessary, and removing the adjustment float. However, the work of changing a large number of suspension ropes into a long one as described above and the work of removing the adjustment float are very troublesome, and there is a problem that the subsidence work is not in time when dealing with a typhoon or low pressure.
(2) (Patent Document 2), two floats are attached to the outer periphery of the aquaculture ginger body, the inner float fixes buoyancy, the outer float has an air hose connected to it, and an air valve with a float is provided. It is provided with a structure that adjusts buoyancy by intake and exhaust from the air valve, and passes through the metal fittings installed on the ginger position fixing anchor installed on the seabed with a plurality of wires attached to the outer frame of the ginger body bottom part. Attach a float for sinking to the tip, draw air from the outer float from the air valve, sink the ginger body, and inject air from the compressor loaded on the ship into the outer float via the air valve and air hose. Although a floating farming ginger for use in the open ocean, characterized by floating the main body, is shown, it has the following problems.
1. The floating farm is a complex structure for use in the sea, and the air hose and feeding pipe are connected from the underwater ginger body to the air valve with a float on the water surface and the feeding port held by the float. Even when the ginger body rises or sinks, the load and impact due to waves and tidal currents are repeatedly applied between the members and the members, which may damage the wires and the joints of the members. There is a problem in durability.
2. Because a compressor is required for the ascent operation, it is constrained in use, and it is assumed that the operation will not be in time when a typhoon such as a typhoon is required. Therefore, there is a high probability that the malfunction of the apparatus will occur, and there remains a problem of lack of versatility, operability, quickness, and manageability.

本考案は、上記課題を解決するために、浮上用フロートが配設された育成部や支持部、方向転換具を備えた固定部、引き込み用フロート、前記の支持部と引き込み用フロートを連結する係留索によって構成され、育成目的生物が保持されている育成部や支持部が、通常は引き込み用フロートによって下方に引き込まれて水面下の所定水深階層に設置され、係留索の長さを調節する操作で所要の水深階層に移動させることができ、状況によって、引き込み用フロートの引き込み作用を解いて浮上させ、そのまま切り離して他の場所に移動できるように係留されたもので、機能性、操作性、安全性、管理性、作業性、堅牢性、保全性、省資源性、汎用性、低コスト性、育成目的生物の健全育成性、成長促進性、生産性、漁場利用性、操業効率性に優れた養殖用水深可変係留施設の提供を目的とする。   In order to solve the above-mentioned problems, the present invention provides a growing part and a supporting part in which a floating float is disposed, a fixing part having a direction changing tool, a retracting float, and connecting the supporting part and the retracting float. The growing part and supporting part, which are composed of mooring lines and hold the target organism, are usually drawn downward by a pulling float and installed at a predetermined depth below the surface of the water to adjust the length of the mooring lines. It can be moved to the required depth level by operation, and depending on the situation, it is moored so that it can be lifted by lifting the pull-in action of the pull-in float and separated and moved to another place, functionality and operability , Safety, manageability, workability, robustness, maintainability, resource saving, versatility, low cost, healthy growth of target organisms, growth promotion, productivity, fishery utilization, operational efficiency An object of the present invention to provide for the aquaculture water depth variable mooring facilities.

上記課題を解決するために、本考案の養殖用水深可変係留施設は、以下の構成を有している。
本考案の請求項1に記載の養殖用水深可変係留施設は、養殖カゴや生簀などの収容体及び/又は、線材、紐体、網体、板材、貝殻などで形成された保持体などが用いられた育成目的生物を育成するための育成部と、前記育成部が取付けられた支持部と、前記育成部及び/又は、前記支持部に配設された浮上用フロートと、土俵やアンカーなどを水底に固定して形成された固定部と、前記固定部に取付けられた方向転換具と、少なくとも前記支持体の片端側に一端側が連結され他端側が前記方向転換具を介して引き込み用フロートに連結された係留索と、を備えている構成を有している。
この構成により以下のような作用を有する。

(3)係留索の長さを調節することにより、育成部を着底させることや、水底近くの所要水深階層に設置することができ、水底付近や底層に生息する育成目的生物に適する環境を提供することができ、水底付近や底層での育成に適する育成目的生物の健全育成性、成長促進性に優れる。
(4)係留索を繰り出すだけの簡単な操作で、労力を要せずに、育成部を浮上させるとともに、支持部や係留索を弛ませることができ、その後の作業が安全且つ容易で、安全性、作業性に優れる。
(5)時化、赤潮、降雨淡水化、水温変動などに対応して、育成部と支持部などを浮上させ、育成部や他の所要部分を係留索などと切り離して、浮かせた状態のままで曳行する方法などで他の場所に避難させることができ、機能性、保全性に優れる。
(6)表層付近に配設される部材が少なく、付着物が付き難いので、酸欠や栄養不足を防ぐことができ、育成目的生物の健全な育成と成長促進が図れ、付着物除去の手間が省け、付着物による負荷が小さく、健全育成性、成長促進性、管理性、保全性に優れる。
(7)目標物や、表層付近の部材が僅かで、盗難が予防でき、引き込み用フロートを水没させることなどの盗難防止策を施すこともでき、水中の係留索はスクリューなどが絡まり難く、操業や航行に支障がなく、施設乗り切り事故が防げ、保全性、安全性に優れる。
(8)波浪による衝撃を受ける部材が引き込み用フロートと係留索に限定され、前記部材に十分な強度と耐久性を有するものが用いられ、前記以外の部材は波浪の影響が比較的に小さいので施設各部が長期間使用でき、保全性、省資源性に優れる。
(9)従来の垂下延縄式では構造面及び操業上の理由から、支持部から係留用の碇綱固定部までの水平距離が水深の2.5〜3倍前後で係留されるが、本考案の養殖用水深可変係留施設は、少なくとも支持部の片端に係留索の一端が連結され、前記係留索の他端が固定部に取付けられた方向転換具を通過した後に、その垂直上方に設置される引き込み用フロートに連結されて係留される構成で、且つ育成部を浮上させる時に前記支持部や前記係留索を弛ませることができるので、前記支持部から前記固定部までの水平距離が水深の0.2倍〜1.5倍前後で係留することができ、施設占有面積が小さく、養殖漁場の競合や輻輳が緩和でき、深い水域においても施設占有面積を抑えて設置することができ、漁場利用性に優れる。
(10)特別な資材や複雑な装置を必要とせず、構成がシンプルで、魚介藻類育成に広く利用でき、比較的安価な材料を用いて容易に組立ができ、安全且つ容易に設置作業を行うことができ、汎用性、低コスト性、安全性、作業性に優れる。

育成部として用いられる収容体や保持体は、育成目的生物の種類、育成条件、支持部への取付方法などに適合するように、材質、形状が選択される。
衝撃や負荷がかかる支持部と係留索には、ポリプロピレンスプリットヤーン製ロープやポリエチレンモノフィラメント製ロープが主として用いられ、強度と耐久性が高く、比重1.0未満で、作業中に放置しても沈まず、取扱性に優れ、安価で経済性に優れている。
浮上用フロート、引き込み用フロートは、施設規模などに応じて、材質、浮力、耐圧性能などを選択することができ、育成期間中に状況を見て増減することもできる。
方向転換具は、係留索を方向転換して所要方向に案内できるものであればよく、一般に滑車が用いられ、ナイロン樹脂製滑車などの堅牢性の高い滑車が好適に用いられる。
The material and shape of the container and holding body used as the growing part are selected so as to match the type of the target organism for growth, the growing conditions, the attachment method to the support part, and the like.
Polypropylene split yarn ropes and polyethylene monofilament ropes are mainly used for the support and mooring lines that are subjected to impacts and loads, and have high strength and durability. First, it is easy to handle, inexpensive and economical.

(Embodiment 1)
The aquaculture water depth variable mooring facility according to Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is a partially omitted schematic front view of the aquaculture water depth variable mooring facility according to the first embodiment.
In FIG. 1, reference numeral 1 denotes aquaculture water depth variable mooring facility according to the first embodiment, 2A and 2B are growth parts supported by hanging on the support part 3, and 2A is a fish, shellfish, sea cucumber, sea urchin, etc. A breeding part using a container such as a fish cage or a cage for fishery products, 2B is a growing part using a holding body for holding seaweed, oysters, etc. formed of ropes or shells, 3 is a breeding part Supporting part using trunk rope to which 2A and 2B are attached, 4 is a floating float arranged on the supporting part 3, and 5 is a case where the growing parts 2A and 2B are installed in the middle depth of water where the growing is always performed. The mooring cable 5A is connected to the end of the support part 3 at one end side, and the mooring cable measuring part 5B is connected to the mooring cable measuring part 5A, and the other end is retracted later. The mooring line middle layer adjusting section of the mooring line 5 connected to the float 8 for the mooring, A fixed part formed on the bottom of the water such as a car, 7 is a direction changer using a pulley attached to the fixed part 6 and guides the mooring line 5, and 8 is connected to the mooring line 5 and supported via the direction changer 7 A retractable float for retracting the portion 3, 9 is a lead, and 9 </ b> A is a mark float attached to the lead 9.

図1では、養殖用水深可変係留施設1に配設される係留索5の内、最短寸法に形成された一対の係留索定尺部5Aの一端側が、支持部3の両端部に各々連結され、それぞれ他端側が方向転換具7で方向転換した後に係留索中層用調節部5Bに連結され、その先が引き込み用フロート8に連結されている。育成部2A,2Bが取付けられている支持部3は、浮上用フロート4によって常に浮上する力が作用しているが、引き込み用フロート8によって引き込まれ、実施の形態1の常時の水深階層である中層に設置されている。
養殖用水深可変係留施設1は、育成部2A,2Bが取付けられた支持部3の両端部を、係留索5によって、水底に形成された固定部6に取付けられた方向転換具7を介して、引き込み用フロート8によって、水底の方向に引き込むように構成されて、水底を基準に係留され、しかも、水面付近に設置される部材がごく僅かであるために施設が波浪や潮流の影響を受け難く、さらに、円筒形の引き込み用フロート8が立錐状に設置されて波浪による上下動が抑制され、その上で、常時は育成部2A,2B、支持部3が中層に設置されるので、表層ほど顕著な波浪や潮流による動揺や吹かれ、水温変動、赤潮、降雨淡水化の影響を受け難くなり、育成目的生物の揺れや震動によるストレスが軽減され、時化による施設の流失や破損を免れることができ、付着物が少ないので酸欠や栄養不足が防止でき、付着物自体や付着物が受ける波浪や潮流の影響を小さくする、という重要な効果が得られる。
方向転換具7から立ち上がっている係留索5は引き込み用フロート8の作用で水中で緊張しているためにスクリューなどが絡まず、操業時や航行中の船舶にとって安全で、船舶による施設への乗り切り事故が防げる。
尚、従来の垂下延縄式は、施設の構造上、表層や上層の波浪や潮流の影響を受けやすく、碇綱固定部の固定力を確保するために碇綱と水底がなす角度を小さくする目的と、波浪による衝撃が碇綱から育成部に伝わりやすくなることを防止するために碇綱の長さを一定以上確保する必要性と、操業で幹縄を引き上げた時に碇綱が張って引き上げ難くなるのを緩和する目的で、幹縄の端部から碇綱固定部までの水平距離を各々、満潮時の水深の2.5〜3倍前後としている。
養殖用水深可変係留施設1は、施設の構造上、表層や上層の波浪や潮流の影響が小さく、波浪による衝撃が育成部2A,2Bや支持部3に伝わり難いように構成されており、さらに、後述のように育成部2A,2Bを浮上させる時に係留索5を繰り出して支持部3や係留索5を弛ませることができるので、支持部3の端から固定部6までの水平距離が、通常は各々、満潮時の水深の1.0〜1.5倍で係留することができ、所要によって水深の0.2倍程度でも係留することができ、施設占有面積が格段に縮小され、漁場の有効利用が図れる。
係留索5は、引き込み用フロート8が波浪によって上下動する時の負荷を受けるので、直径18〜40mm、引っ張り強さ4〜16トン前後の、主としてポリプロピレンスプリットヤーン製ロープや、ポリエチレンモノフィラメント製ロープなどが用いられ、係留索5以外は大きな衝撃が掛からないが、係留索5に準じた材料を用いることによって、施設全体が長期に使用できるように構成される。
浮上用フロート4、引き込み用フロート8の耐圧は水深50m以上とし、浮上用フロート4は幹縄3の各部が略同一水深に設置されるように配分され、引き込み用フロート8は1本の係留索5に対し1つに限らず、深さ方向や水平方向に複数配設することができる。
固定部6が土俵で形成される場合は引き込み用フロート8の浮力の4倍以上の水中質量とすることが望ましく、小規模な施設でも1ケ所の合計水中質量を1000kg以上とし、方向転換具7を固定するロープリングに個々の土俵を括り付けて設置する。尚、固定部6は土俵の代わりにコンクリートブロック、打ち込み式アンカー等で形成してもよい。
ここで、魚介類育成を主とする育成部2A、海藻育成を主とする育成部2Bを併設したのは、魚介類と海藻類の複合育成による生産効率向上と、水質改善などの環境保全を目的としたもので、以下の各実施の形態でも同様に随時採用できる。
In FIG. 1, one end side of a pair of mooring rope fixed-length portions 5 </ b> A formed in the shortest dimension among the mooring wires 5 disposed in the aquaculture water depth variable mooring facility 1 is respectively connected to both end portions of the support portion 3. The other end side is changed by the direction changer 7 and then connected to the mooring line middle layer adjusting portion 5B, and the tip thereof is connected to the retracting float 8. The support part 3 to which the growing parts 2A and 2B are attached is always subjected to a force that ascends by the floating float 4, but is drawn by the pulling float 8, and is a normal water depth layer of the first embodiment. It is installed in the middle layer.
The aquaculture water depth variable mooring facility 1 has both ends of the support part 3 to which the breeding parts 2A and 2B are attached via the direction changer 7 attached to the fixed part 6 formed on the bottom of the water by the mooring line 5. It is constructed so as to be drawn in the direction of the bottom of the water by the draw-in float 8 and is moored with reference to the bottom of the water. Moreover, since there are very few members installed near the water surface, the facility is affected by waves and tides. In addition, since the cylindrical pull-in float 8 is installed in a vertical cone shape, the vertical movement due to the waves is suppressed, and the growth parts 2A and 2B and the support part 3 are always installed in the middle layer. It is less susceptible to the effects of wave and tidal currents, fluctuations in water temperature, red tides, and rainwater desalination, reducing the stress caused by shaking and shaking of the target organisms, and avoiding the loss or damage of facilities due to aging Can Can, because deposit is less prevents insufficient oxygen deficiency and nutrients, to reduce the influence of wave and tidal current deposits itself and deposits undergo important effect that can be obtained.
The mooring line 5 standing up from the direction changer 7 is tensioned in the water due to the action of the pull-in float 8 and is not entangled with screws. Accidents can be prevented.
In addition, the conventional hanging longline type is easily affected by waves and tides on the surface and upper layers due to the structure of the facility, and the purpose is to reduce the angle between the leopard and the bottom of the water to secure the anchorage of the leash In order to prevent the shock caused by waves from being easily transmitted from the leash to the breeding department, it is necessary to secure the length of the leash more than a certain level, and when the trunk line is raised during operation, the leash is stretched and difficult to pull up. In order to alleviate this, the horizontal distance from the end of the trunk rope to the anchor rope fixing part is about 2.5 to 3 times the water depth at high tide.
The aquaculture water depth variable mooring facility 1 is structured so that the influence of waves and tides on the surface layer and upper layer is small due to the structure of the facility, and the impact caused by the waves is not easily transmitted to the breeding parts 2A, 2B and the support part 3. As will be described later, the mooring line 5 can be extended when the growing parts 2A and 2B are levitated to loosen the support part 3 and the mooring line 5, so that the horizontal distance from the end of the support part 3 to the fixed part 6 is Normally, each can be moored at 1.0 to 1.5 times the water depth at high tide, and can be moored at about 0.2 times the water depth if necessary, and the area occupied by the facility is greatly reduced, Can be used effectively.
The mooring line 5 receives a load when the pull-in float 8 moves up and down due to waves, so that it is mainly made of polypropylene split yarn or polyethylene monofilament rope having a diameter of 18 to 40 mm and a tensile strength of about 4 to 16 tons. However, a large impact is not applied except for the mooring line 5, but by using a material according to the mooring line 5, the entire facility can be used for a long time.
The levitation float 4 and the pull-in float 8 have a pressure resistance of 50 m or more, the levitation float 4 is distributed so that each part of the trunk 3 is installed at substantially the same depth, and the pull-in float 8 is one mooring cable. The number is not limited to one for five, but a plurality can be arranged in the depth direction and the horizontal direction.
When the fixing portion 6 is made of earth, it is desirable that the underwater mass is four times or more the buoyancy of the draw-in float 8, and even in a small-scale facility, the total underwater mass is 1000 kg or more. Each rope is tied to the rope ring that secures. Note that the fixing portion 6 may be formed of a concrete block, a driven anchor, or the like instead of the earthwork.
Here, the breeding part 2A mainly for seafood breeding and the breeding part 2B mainly for seaweed breeding are added to improve the production efficiency by the combined breeding of seafood and seaweed, and environmental conservation such as water quality improvement. It is intended, and can be adopted at any time in the following embodiments as well.

図2は実施の形態1の養殖用水深可変係留施設の育成部を上層に移動させた状態を示す一部省略模式正面図である。
図2中、5' は育成部2A,2Bを上層に設置するための係留索、5Cは係留索5'の係留索上層用調節部である。
図2では、左右の係留索定尺部5Aに対して、係留索中層用調節部5Bより長い係留索上層用調節部5Cを各々連結したことによって係留索5’が構成され、育成部2A,2Bを上層に移動させている。
図2は、春先から初夏などの水温上昇期などにおいて、育成部2A,2Bを適水温に近づける目的で、図1に示された通常の水深階層の中層から上層に移動させた状態であり、このように係留索の長さを変えるだけで育成目的生物の適水温帯に近い水深階層に育成部2A,2Bを容易に移動させることができ、成長促進を図ることができる。
育成部2A,2Bは上層に設置されているが、施設が水底の方向転換具7を介して、引き込み用フロート8で水底方向に引き込むように構成され、水底を基準に設置されているので動揺や衝撃が抑えられ、育成目的生物が大きなストレスを受けることがなく、大きな時化以外の通常の操業において施設の保全が図れる。
FIG. 2 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility of the first embodiment is moved to the upper layer.
In FIG. 2, 5 'is a mooring line for installing the growing parts 2A and 2B in the upper layer, and 5C is a mooring line upper layer adjusting part for the mooring line 5'.
In FIG. 2, the mooring line 5 'is connected to the right and left mooring line measuring part 5A by connecting the mooring line upper layer adjusting part 5C longer than the mooring line middle layer adjusting part 5B. 2B is moved to the upper layer.
FIG. 2 shows a state in which the breeding units 2A and 2B are moved from the middle layer to the upper layer in the normal water depth hierarchy shown in FIG. In this way, by simply changing the length of the mooring line, it is possible to easily move the breeding units 2A and 2B to the depth level close to the appropriate water temperature zone of the target organism for growth, thereby promoting growth.
The breeding units 2A and 2B are installed in the upper layer, but the facility is configured to be drawn in the water bottom direction with the draw-in float 8 via the water bottom direction changer 7, and is shaken because it is installed with reference to the water bottom. And the impact is suppressed, the target organism is not subject to great stress, and the facility can be preserved in normal operations other than large storms.

図3は実施の形態1の養殖用水深可変係留施設の育成部を底層に移動させた状態を示す一部省略模式正面図である。
図3中、5”は育成部2A,2Bを底層に移動させるために係留索定尺部5Aが単独で配設された係留索である。
図3では、係留索5”(係留索定尺部5A)が引き込み用フロート8に直接連結されたことによって、支持部3が引き込まれて育成部2A,2Bが底層に移動している。
従来の垂下延縄式の場合は、水面フロートを基準に設置されるので強い波浪や潮流を受けるために、水深が深くなるほど育成部の吹かれが大きくなり、所要水深に設置することが困難であったが、本考案の水深可変係留施設はいずれも、支持部3の両端部にそれぞれ係留索5の一端側が連結され、係留索5の他端側が水底の固定部6に取付けられた方向転換具7を介して、引き込み用フロート8に接続され、支持部3が水底の方向に引き込むように構成されて、水底を基準に設置されるので、所要の水深階層に設置することができ、深く沈めることによって波浪や潮流の影響を抑えることができ、台風や層の厚い赤潮などの被害を防ぐことができ、深い水深階層や底層付近での育成に適する育成目的生物に対して好適な環境を提供することができる。
図3で、引き込み用フロート8を水没させ、引き込み用フロート8に分径18mm前後で比重1.3前後の導索9の一端を接続し、他端に目印フロート9Aを取付けているが、この状態は部外者に施設の存在が探知され難く、施設の部材や育成目的生物の盗難が予防できる。
FIG. 3 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the first embodiment is moved to the bottom layer.
In FIG. 3, reference numeral 5 ″ denotes a mooring line in which the mooring line measuring part 5A is arranged independently to move the growing parts 2A and 2B to the bottom layer.
In FIG. 3, the mooring line 5 ″ (the mooring line measuring part 5A) is directly connected to the retracting float 8, so that the support part 3 is drawn and the growing parts 2A and 2B are moved to the bottom layer.
In the case of the conventional hanging longline type, since it is installed based on the water surface float, in order to receive strong waves and tidal currents, the deeper the water depth, the greater the blowing of the growing part becomes, making it difficult to install at the required water depth. However, in all of the variable depth mooring facilities of the present invention, one end side of the mooring line 5 is connected to both ends of the support part 3, and the other end side of the mooring line 5 is attached to the fixed part 6 of the water bottom. 7 is connected to the draw-in float 8, and the support portion 3 is configured to be drawn in the direction of the bottom of the water, and is installed with reference to the bottom of the water, so that it can be installed at the required depth level and submerged deeply. Can suppress the effects of waves and tidal currents, prevent damages such as typhoons and thick red tides, and provide a suitable environment for target organisms suitable for breeding near deep water depths and bottom layers To do Kill.
In FIG. 3, the pull-in float 8 is submerged, and one end of a lead 9 having a diameter of about 18 mm and a specific gravity of about 1.3 is connected to the pull-in float 8 and a mark float 9A is attached to the other end. It is difficult for outsiders to detect the existence of the facility, and it is possible to prevent theft of the members of the facility and the breeding target organism.

図4は実施の形態1の養殖用水深可変係留施設の育成部を水面付近に浮上させた状態を示す一部省略模式正面図である。
図4中、5Dは係留索5”(係留索定尺部5A)と引き込み用フロート8を連結する繰り出し索である。
図4は、図3の次に行う作業手順として、片側の係留索5”(係留索定尺部5A)が引き込み用フロート8から取外され、繰り出し索5Dが接続されて引き込み作用が解かれ、浮上用フロート4の浮力で支持部3に続いて育成部2A,2Bが浮上し、支持部3や係留索5”(係留索定尺部5A)が弛んでいるので、支持部3を手繰って育成部2A,2Bを手元に引き寄せることができ、船上に引き上げることも容易にでき、育成目的生物の収穫や各部のメンテナンスなどの所要の作業が迅速に実施できる。
尚、前記手順に準じて、図1の係留索中層用調節部5Bや、図2の係留索上層用調節部5Cに各々繰り出し索5Dを接続して延ばすことによって、支持部3を容易に浮上させることができ、その後の所要の作業が前記同様に実施できる。
さらに、図示しないが、時化、赤潮、降雨淡水化、水温変動などに対して、支持部3の両端部に連結されている係留索5”(係留索定尺部5A)を切り離すことによって育成部2A,2B、支持部3、浮上用フロート4で構成された所要部分を曳行するなどの方法で安全な場所へ移動することができ、避難した先で一時係留した後に元の場所に戻して、図1乃至図3の状態に復旧することもできる。
また、育成部や支持部を浮上させるとともに支持部や係留索を弛ませる操作は、本考案のいずれの実施の形態においても略同様に行うことができる。
FIG. 4 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the first embodiment is floated near the water surface.
In FIG. 4, 5D is a feed line that connects the mooring line 5 ″ (the mooring line measuring part 5A) and the retracting float 8.
FIG. 4 shows a work procedure performed next to FIG. 3, in which one side of the mooring line 5 ″ (the mooring line measuring part 5A) is removed from the pull-in float 8 and the extension line 5D is connected to release the pull-in action. Since the buoyancy of the float 4 for levitation causes the growing parts 2A and 2B to float after the support part 3 and the support part 3 and the mooring line 5 ″ (the mooring line measuring part 5A) are loosened, the support part 3 is reworked. Thus, the breeding units 2A and 2B can be drawn close to each other, can be easily pulled up on the ship, and necessary operations such as harvesting of target organisms and maintenance of each unit can be quickly performed.
In accordance with the above procedure, the support portion 3 can be easily lifted by connecting and extending the feeding line 5D to the mooring line middle layer adjusting part 5B in FIG. 1 and the mooring line upper layer adjusting part 5C in FIG. The required work thereafter can be performed in the same manner as described above.
Further, although not shown in the figure, the mooring line 5 "(the mooring line measuring part 5A) connected to both ends of the support part 3 is separated by detaching the mooring line 5" (the mooring line measuring part 5A) with respect to aging, red tide, rainwater desalination, water temperature fluctuation, and the like. It can be moved to a safe place, such as by coasting the required part composed of the parts 2A, 2B, the support part 3, and the floating float 4, and after being temporarily moored at the evacuation destination, it is returned to the original place. 1 to FIG. 3 can be restored.
In addition, the operation of floating the growing portion and the support portion and loosening the support portion and the mooring line can be performed in substantially the same manner in any of the embodiments of the present invention.

尚、図3の状態から、片方の引き込み用フロート8に音波作動式ストッパーを取付けて目印フロート9Aを固定した後に、引き込み用フロート8と目印フロート9Aを沈めて、もう一方の目印フロート9Aを取外すこともできる。これにより、水面上の目標物を無くすことができ、魚群探知機などで施設が探知されても水面上の手掛かりが皆無で、盗難防止効果を高めることができる。所要時には、音波作動で前記音波作動式ストッパーを解除して、固定されていた目印フロート9Aを浮上させ、以下前記に準じた操作で支持部3を浮上させることができる。   From the state of FIG. 3, after attaching the sonic actuation type stopper to one drawing float 8 and fixing the mark float 9A, the drawing float 8 and mark float 9A are submerged and the other mark float 9A is removed. You can also. Thereby, the target on the water surface can be eliminated, and even if the facility is detected by a fish finder or the like, there is no clue on the water surface, and the antitheft effect can be enhanced. When necessary, the sound wave actuated stopper is released by sound wave operation, the fixed mark float 9A is floated, and the support part 3 can be floated by an operation according to the above.

図5中、5aは係留索定尺部5Aの端部に形成された連結用アイ、5bは係留索中層用調節部5Bの両端部に形成された連結用アイ、8aは引き込み用フロート8に配設された連結用アイ、10は隣接する各連結部同士を固縛して連結する固縛索である。
図5では、係留索定尺部5Aの連結用アイ5aと係留索中層用調節部5Bの下側の連結用アイ5bが固縛索10で連結され、係留索中層用調節部5Bの上側の連結用アイ5bと引き込み用フロート8の連結用アイ8aが固縛索10で連結されている。
一般の結索による連結部の破断強力(強度)は直線強力比で50〜70%であるが、図5に示された連結用アイ5a,5b,8aを固縛索10で連結する方法は、直線強力比90%前後となり、連結部の強度が強く、固縛及び解除作業が容易で、シャックルなどの連結用金具使用の場合は解除が困難な緊張状態においても、固縛索10を切断するだけで安全且つ迅速に切り離すことができ、堅牢性、作業性、安全性に優れる。

(Embodiment 2)
The aquaculture water depth variable mooring facility according to the second embodiment of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the thing similar to Embodiment 1, and description is abbreviate | omitted.
FIG. 6 is a partially omitted schematic front view of the aquaculture water depth variable mooring facility according to the second embodiment.
In FIG. 6, reference numeral 11 denotes aquaculture water depth variable mooring facility according to the second embodiment, 12 is a grounding part that is mainly used for landing, and a rearing part using a culture basket formed in a circular shape or a rectangular shape in plan view, and 12A A suspension hand for attaching the upper part of the growing part 12 to a support part 13 to be described later, 13 is a support part using a trunk rope, 14A is a floating float for bottoming adjustment attached to both ends of the support part 13, Reference numeral 14B denotes a floating float disposed on the support portion 13, and reference numeral 15 denotes a mooring line used for landing the growing portion 12 on a water bottom that is always installed.

図6には、係留索15が連結された引き込み用フロート8の作用で支持部13が底層に引き込まれ、育成部12が着底し、吊り手12Aが弛んでいる状態が示されている。
実施の形態2の養殖用水深可変係留施設11が、実施の形態1の養殖用水深可変係留施設1と異なる点は、育成部12と中の育成目的生物などの被収容物の水中重量に対して、浮上用フロート14Bの浮力を小さく設定し、着底調整用の浮上用フロート14Aで浮力を補うようにして引き込み作用を解いた時に浮上するように構成し、育成部12の通常の設置位置である水底に引き込んだ時に着底調整用の浮上用フロート14Aの浮上作用を抑えるようにして、育成部12を安定した状態で着底させるようにしたことである。
水底付近では時化や潮流の影響が小さいので施設の流失や破損が防止でき、育成部12が着底した状態では、ホタテ、アワビ、イワガキ、ウニ、ナマコなどの、本来は水底付近での育成に適する育成目的生物に好ましい環境が与えられ、さらに、育成部12が動揺しないので内部に砂や土などを入れて育成することができ、タイラギ、アカガイ、ナマコなどを一層好適な条件下で成長促進させることができる。
尚、水底付近では食害を受けやすく、軟泥ヘドロによる育成部12の埋没が起こりやすいので、育成部12として用いられる養殖カゴの網目を小さくして食害を防ぐことや、埋没しないような条件の水底を選択することが望まれる。
ここで、実施の形態2の養殖用水深可変係留装置11は、育成部12を常時着底させて設置するために係留索15に掛かる衝撃などが伝わり難いので、係留索15の支持部13の端部と固定部6に取付けられている方向転換具7の間を短くすることができ、支持部13の端部から固定部6までの水平距離を満潮時の水深の0.4倍ほどで係留している。
これによって、水深が深い漁場や、施設が輻輳している漁場において施設の占有面積を抑えることができる。
FIG. 6 shows a state in which the support portion 13 is drawn into the bottom layer by the action of the pull-in float 8 to which the mooring line 15 is connected, the growing portion 12 is landed, and the suspension hand 12A is slack.
The aquaculture depth variable mooring facility 11 according to the second embodiment is different from the aquaculture depth variable mooring facility 1 according to the first embodiment with respect to the underwater weight of the contents to be accommodated such as the breeding unit 12 and the rearing target organism. The buoyancy of the float for float 14B is set to a small value, and the float is floated when the pull-in action is solved by compensating the buoyancy with the float float 14A for bottoming adjustment. This is to suppress the floating action of the floating float 14A for adjusting the bottom when it is drawn into the water bottom, so that the growing part 12 is bottomed in a stable state.
Near the bottom of the water, the effects of aging and tidal currents are small, so the facility can be prevented from being lost or damaged. With the breeding unit 12 in the bottom, scallops, abalone, scallops, sea urchins, sea cucumbers, etc. The environment is suitable for the target organism suitable for growth, and since the breeding unit 12 does not shake, it can be cultivated with sand or soil inside, and larvae, red shellfish, sea cucumber, etc. are grown under more suitable conditions Can be promoted.
In addition, since it is easy to receive a food damage near the bottom of the water, and the burying of the growing part 12 is likely to occur due to the sludge sludge, the bottom of the condition is such that the mesh of the cultured cage used as the growing part 12 is reduced to prevent the food damage or the burial is not buried. It is desirable to select
Here, in the aquaculture water depth variable mooring apparatus 11 of the second embodiment, since the impact applied to the mooring line 15 is difficult to be transmitted in order to install the growing part 12 with the bottom always attached, it is difficult to transmit the support part 13 of the mooring line 15. The distance between the end and the direction changer 7 attached to the fixed part 6 can be shortened, and the horizontal distance from the end of the support part 13 to the fixed part 6 is about 0.4 times the water depth at high tide. Moored.
As a result, the occupied area of the facility can be suppressed in a fishing ground with a deep water depth or a fishing ground where the facility is congested.

図7中、15Dは各々係留索15と引き込み用フロート8の間に接続された繰り出し索である。
図7では、片側の係留索15が引き込み用フロート8から取外され、繰り出し索15Dが接続されて繰り出され、引き込み作用が解かれて浮沈調整用の浮上用フロート14A,14Bの浮力で育成部12が支持部13とともに浮上している。
この時、育成部12は水面下にあるが、支持部13が弛んでいるので手繰りやすく、吊り手12Aを引いて水面に引き上げることができ、船上に引き上げることもでき、投餌、清掃、収穫などの作業を容易に行うことができる。さらに、図示しないが、支持部13の両端部に連結されている係留索15を切り離すことによって育成部12、支持部13、浮上用フロート14A,14Bで構成された所要部分を曳行するなどの方法で安全な場所へ移動することができ、避難した先で一時係留した後に元の場所に戻して、図6の状態に復旧することも容易にできる。
FIG. 7 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the second embodiment is levitated near the water surface.
In FIG. 7, reference numerals 15 </ b> D denote feeding cables connected between the mooring cable 15 and the pull-in float 8.
In FIG. 7, the mooring line 15 on one side is removed from the float 8 for pull-in, and the feed line 15D is connected and unwound. 12 floats together with the support portion 13.
At this time, the growing part 12 is under the water surface, but the support part 13 is loose, so that it is easy to handle, the suspension hand 12A can be pulled up to the water surface, can be pulled up on the ship, feeding, cleaning, harvesting Etc. can be easily performed. In addition, although not shown, a method of coasting a required portion composed of the growing portion 12, the support portion 13, and the floats 14 </ b> A and 14 </ b> B by cutting off the mooring lines 15 connected to both ends of the support portion 13. 6 can be moved to a safe place, and after being temporarily moored at the evacuated place, it can be easily returned to the original place and restored to the state of FIG.

以上のように実施の形態2の養殖用水深可変係留施設は構成されているので、以下の作用が得られる。
(1)育成部12を安定した状態で着底させることができ、時化や潮流の影響が小さく、赤潮、降雨淡水化、水温変動が及び難く、育成目的生物が動揺によるストレスを受けず、育成部12の内部に砂や土などを収容することによって育成目的生物の成長が促進でき、施設の流失や破損が防止でき、健全育成性、成長促進性、保全性に優れる。
(2)支持部13の端部から固定部6までの距離を短くして、水深の半分以下でも係留することができ、水深が深い漁場や、施設が輻輳している漁場で、施設占有面積を小さくして係留することができ、漁場利用性に優れる。
Since the aquaculture water depth variable mooring facility according to the second embodiment is configured as described above, the following actions are obtained.
(1) The breeding unit 12 can be settled in a stable state, the influence of aging and tides is small, red tide, rainfall desalination, water temperature fluctuations are difficult, and the target organism is not subject to stress due to shaking, By accommodating sand, soil, or the like inside the breeding unit 12, the growth of the target organism can be promoted, the facility can be prevented from being washed away or damaged, and the healthy breeding property, growth promoting property, and maintainability are excellent.
(2) The distance from the end of the support portion 13 to the fixed portion 6 can be shortened and moored at a depth of less than half the depth of the water. It can be moored with a small size and excels in fishing ground availability.

(実施の形態3)
本考案の実施の形態3における養殖用水深可変係留施設について、図面を参照しながら以下説明する。尚、実施の形態1と同様のものには同一の符号を付して説明を省略する。
図8は実施の形態3の養殖用水深可変係留施設の一部省略模式正面図である。

(Embodiment 3)
An aquaculture water depth variable mooring facility according to Embodiment 3 of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the thing similar to Embodiment 1, and description is abbreviate | omitted.
FIG. 8 is a partially omitted schematic front view of the aquaculture water depth variable mooring facility according to the third embodiment.
In FIG. 8, 21 is an aquaculture water depth variable mooring facility according to the third embodiment, 22 is an example of a breeding section, and a breeding section using a cylindrical or rectangular tubular farm basket that is formed long in the left-right direction in the figure. 22A is a suspension for attaching the lower part of the growing part 22 to the support part 23 using the trunk rope, and 23A is formed of a rope body similar to the support part 23, and is arranged in parallel with the support part 23. The second support part 23a is connected to the upper part of the support part 23a. The connection part 23a is formed on both ends of the support part 23 and connected to the ends of the mooring line 25 and the rope 27 described later. Floating float attached to the part 23A, 25 is a mooring line for installing the growing part 22 on the bottom layer, 26 is a rope anchoring part formed of soil on the bottom of the water, 27 is one end side of the support part 23 and the rope This is a leash that connects the fixing portion 26.

実施の形態3の養殖用水深可変係留施設21が、実施の形態1,2の養殖用水深可変係留施設1,11と異なる点は、支持部23の片端側が碇綱27によって碇綱固定部26に連結されていることと、支持部23と第二支持部23Aが深さ方向に並列して配設され、その間に養殖カゴを用いた育成部22が設置されていることである。
図8では、支持部23の片端側が碇綱固定部26と碇綱27によって係留され、他端側が引き込み用フロート8,方向転換具7を備えた固定部6,育成部22を底層に設置するための係留索25によって係留され、支持部23が水底近くに引き込まれて育成部22が常時設置する階層である底層に設置されている。
これによって、夏場の高水温などの水温変動、赤潮、降雨淡水化による影響が小さく、育成目的生物を守ることができ、アワビ、アカガイ、ウニ、ナマコなどの、本来は水底に生息する育成目的生物の育成において好適な環境が得られ、時化に対して十分に施設保全が図れる。
尚、水底付近での育成を必要とする育成目的生物の場合、育成部22を水底に着地させると甲殻類などの食害を受けることや、水底付近の軟泥やヘドロで育成部22が埋没することなどによって、育成目的生物の病気や斃死を招く場合があるが、本実施の形態3の養殖用水深可変係留施設21は、仮に支持部23が着底した場合でも育成部22を水底から吊り手22Aの長さ分だけ水底から離すことができ、着底した時に受けやすい食害や軟泥などによる埋没が防止され、良好な育成環境を維持することができる。
The aquaculture depth variable mooring facility 21 according to the third embodiment is different from the aquaculture depth variable mooring facilities 1 and 11 according to the first and second embodiments in that one end side of the support portion 23 is connected to the leopard fixing portion 26 by the leash rope 27. And the support part 23 and the second support part 23A are arranged in parallel in the depth direction, and the breeding part 22 using the cultured basket is installed between them.
In FIG. 8, one end side of the support portion 23 is moored by the leash rope fixing portion 26 and the leash rope 27, and the other end side is provided with the retraction float 8 and the fixing portion 6 including the direction changer 7 and the growing portion 22 in the bottom layer. It is moored by a mooring line 25 for the purpose, and the support part 23 is drawn into the vicinity of the water bottom, and is installed in the bottom layer, which is a level where the growing part 22 is always installed.
As a result, water temperature fluctuations such as high water temperature in summer, red tides, rainwater desalination are less affected, and the target organisms can be protected. A suitable environment can be obtained in the training of facilities and sufficient facility maintenance can be achieved against aging.
In the case of a target organism that needs to be grown near the bottom of the water, if the growing portion 22 is landed on the bottom of the water, it will be damaged by shellfish, etc., or the growing portion 22 may be buried with soft mud or sludge near the bottom of the water. However, the aquaculture depth variable mooring facility 21 of the third embodiment suspends the breeding unit 22 from the bottom of the water even if the support unit 23 is grounded. It can be separated from the water bottom by the length of 22A, and can be prevented from being buried due to food damage or soft mud that is easily received when the bottom reaches the bottom, and a good growing environment can be maintained.

実施の形態3の養殖用水深可変係留施設21は、育成部22の水深を変える操作を係留索25の側1ケ所で行うので、実施の形態1の養殖用水深可変係留施設1よりも短時間で操作でき、時化などに対する育成目的生物と施設の保全対応が一層速やかにできる。
また、支持部23の片側が碇綱固定部26で係留されているので施設の揺れや移動を低減して安定性が増し、育成部22が、吊り手22Aを介して支持部23によって下方に引かれるとともに、上部が浮上用フロート24の浮力で上方に引かれているので、安定した状態が保たれる。さらに、通常の施設の向きとして、施設の長手方向に潮流が当たるように設置された時に、育成部22や支持部23の吹かれや流水抵抗が抑えられるので、魚類、貝類、ウニ、ナマコなどの育成目的生物のストレスが抑えられ、潮流による施設への負荷を軽減することができ、流失や破損を防ぐことができる。
水面付近では、係留索25が連結された引き込み用フロート8と目印フロート9Aが浮いているだけで、水中で緊張状態の係留索25はスクリューが絡まることがなく、目印フロート8Aが取付けられた導索8は沈む材料を用いているので絡まることが少なく、操業や船舶の航行が安全で、付近を通過する船舶による乗り切り事故を防ぐことができる。また、水面上の目標物が少なく、施設の存在が探知され難いので、部外者による盗難が予防できる。さらに、実施の形態1の養殖用水深可変係留施設1と略同様の操作で、引き込み用フロート8を水没させることもでき、これらに必要な操作も係留索25の側1ケ所で実施できる。
従来の垂下延縄式の場合は、支持部としての幹縄の端部から碇綱固定部までの水平距離が各々水深の2.5〜3倍前後で係留されるが、同じ様に碇綱を用いる実施の形態3の養殖用水深可変係留施設21は、支持部23の端部から固定部6まで、又は碇綱固定部26までの水平距離が各々、満潮時の水深の1.0〜1.5倍程度で係留することができ、施設占有面積を格段に小さくすることができる。
尚、碇綱17、支持部23、係留索25には実施の形態1の養殖用水深可変係留1に用いられた係留索5と略同様のものが使用される。
育成部22として用いられる養殖カゴは、実施の形態2の養殖用水深可変係留施設11の育成部12に準じて、遮蔽率が小さく、水交換性、残餌や排泄物の流出性に優れたものが望まれ、金属製枠体や特殊ロープ製枠体と網体の組合せなどが好適に用いられる。
The aquaculture variable depth mooring facility 21 of the third embodiment performs the operation of changing the water depth of the breeding unit 22 at one place on the mooring line 25 side, so that it is shorter than the aquaculture variable depth mooring facility 1 of the first embodiment. It is possible to operate the target organisms and the facility for breeding with respect to aging.
Further, since one side of the support part 23 is moored by the leash fixing part 26, the shaking and movement of the facility are reduced and stability is increased, and the growing part 22 is moved downward by the support part 23 via the suspension 22A. In addition to being pulled, the upper part is pulled upward by the buoyancy of the floating float 24, so that a stable state is maintained. Furthermore, as a normal facility orientation, when the tidal current is installed in the longitudinal direction of the facility, the blowing of the breeding part 22 and the support part 23 and running water resistance can be suppressed, so fish, shellfish, sea urchins, sea cucumbers, etc. It is possible to reduce the stress of the target organisms for the breeding, reduce the load on the facility due to the tidal current, and prevent the loss and damage.
In the vicinity of the water surface, the pulling float 8 and the mark float 9A to which the mooring line 25 is connected are only floating, and the mooring line 25 in tension in the water does not get tangled with the screw, and the guide float 8A is attached. Since the rope 8 is made of a sinking material, it is less likely to get entangled, and the operation and navigation of the ship are safe, and it is possible to prevent a ride-off accident caused by a ship passing nearby. In addition, since there are few targets on the surface of the water and it is difficult to detect the existence of facilities, theft by outsiders can be prevented. Furthermore, the float 8 for drawing-in can be submerged by substantially the same operation as that for the aquaculture water depth variable mooring facility 1 of the first embodiment, and operations necessary for these can be performed at one place on the side of the mooring line 25.
In the case of the conventional hanging longline type, the horizontal distance from the end of the trunk rope as a support part to the rope anchoring part is moored at about 2.5 to 3 times the water depth, respectively. In the aquaculture water depth variable mooring facility 21 of the third embodiment to be used, the horizontal distance from the end of the support portion 23 to the fixing portion 6 or the leopard fixing portion 26 is 1.0 to 1 of the water depth at high tide. It can be moored at about 5 times, and the area occupied by the facility can be significantly reduced.
Note that the rope 17, the support portion 23, and the mooring line 25 are substantially the same as the mooring line 5 used in the aquaculture water depth variable mooring 1 of the first embodiment.
The aquaculture basket used as the breeding unit 22 has a low shielding rate and excellent water exchange, residual feed and excrement outflow characteristics, similar to the breeding unit 12 of the aquaculture water depth variable mooring facility 11 of the second embodiment. A metal frame or a combination of a special rope frame and a net is preferably used.

図9は実施の形態3の養殖用水深可変係留施設の育成部を上層に移動させた状態を示す一部省略模式正面図である。
図9中、25'は育成部22を上層に移動させる時に用いられる係留索、25Aは係留索25を兼ねて用いられるもので係留索25'の係留索定尺部、25Cは係留索留索定尺部25Aと引き込み用フロート8を連結する係留索25'の係留索上層用調節部である。
図9では、支持部23の片端側が、係留索定尺部25Aと係留索上層用調節部25Cを接続した係留索25'によって係留され、育成部22が上層に設置されている。
この状態は貝類、ウニ、ナマコなどの、水底付近での育成に適する育成目的生物に対して春から初夏の水温上昇期や初冬の水温下降期などに、適水温に近い上層付近で育成する時などに実施されるもので、極力適水温に近い水温帯で育成促進を図るとともに、育成部22が上層に設置されてはいるが、前記施設の構成によって安定して動揺や吹かれが抑えられ、水面から所定深さの階層に沈められているので、通常想定される程度の夏期の高水温、時化や降雨による淡水化、赤潮などの影響を避けることができる。
FIG. 9 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the third embodiment is moved to the upper layer.
In FIG. 9, 25 ′ is a mooring line used when moving the growing part 22 to the upper layer, 25 A is also used as the mooring line 25, and a mooring line fixed part of the mooring line 25 ′, and 25 C is a mooring line It is a mooring line upper layer adjustment part of the mooring line 25 ′ that connects the standard part 25 </ b> A and the pull-in float 8.
In FIG. 9, one end side of the support portion 23 is moored by a mooring line 25 ′ that connects a mooring line measuring portion 25 </ b> A and a mooring line upper layer adjustment unit 25 </ b> C, and the growing portion 22 is installed in the upper layer.
This is the case when shellfish, sea urchins, sea cucumbers, etc. that are suitable for breeding near the bottom of the water, when they are grown near the upper layer close to the appropriate water temperature, such as during the water temperature rising period from spring to early summer or the water temperature falling period in early winter. While promoting the growth in a water temperature zone as close as possible to the optimum water temperature, the growth part 22 is installed in the upper layer, but the structure of the facility can stably suppress shaking and blowing. Since it is submerged in a hierarchy at a predetermined depth from the water surface, it is possible to avoid the effects of summer high water temperature, desalination due to aging and rainfall, red tide, etc. as expected.

図10は実施の形態3の養殖用水深可変係留施設の育成部を水面付近に浮上させた状態を示す一部省略模式正面図である。
図10中、25Dは係留索25を繰り出す時に係留索25と引き込み用フロート8の間に接続される繰り出し索である。
図10では、係留索25を引き込み用フロート8から外して、繰り出し索25Dを接続して繰り出したことによって、引き込み用フロート8の引き込み作用が解かれ、浮上用フロート24の浮力で第二支持部23A、育成部22、支持部23の順で浮上し、第二支持部23A、支持部23、碇綱17が弛んでいるので、どの部材にも負荷が掛からず、水面に浮上した第二支持部23Aを手繰って育成部22を作業船に引き寄せることや船上に引き上げることができ、清掃、投餌、選別、収穫などの作業を容易に行うことができる。
従来の垂下延縄式の場合は、育成部や育成目的生物の自重などの他に、碇綱の張力が掛かり、育成部を水面や船上に引き上げるには引き上げ能力の大きい機器を要し、水中から幹縄を引き上げるにつれて碇綱が強く張るために幹縄が張って、育成部に関わる作業に危険が伴うものであったが、本考案の各実施の形態の養殖用可変係留施設は、いずれも、引き上げ作業を行わなくとも育成部などの所要部分が浮上するとともに、支持部、係留索、碇綱が弛むので浮上後の所要作業を安全で容易に行うことができる。
FIG. 10 is a partially omitted schematic front view showing a state where the breeding part of the aquaculture water depth variable mooring facility according to the third embodiment is levitated near the water surface.
In FIG. 10, reference numeral 25 </ b> D denotes a feeding line connected between the mooring line 25 and the pull-in float 8 when the mooring line 25 is drawn out.
In FIG. 10, the mooring line 25 is removed from the drawing float 8 and the drawing line 25D is connected to the drawing line 25D so that the drawing action of the drawing float 8 is released. Since the second support portion 23A, the support portion 23, and the rope 17 are slackened, the second support surfaced on the water surface without any load being applied. The breeding unit 22 can be pulled to the work ship by pulling the part 23A, and operations such as cleaning, feeding, sorting, and harvesting can be easily performed.
In the case of the conventional hanging longline type, in addition to the weight of the breeding unit and the target organism, the tension of the leopard rope is applied, and in order to lift the breeding unit to the surface of the water or on the ship, equipment with a large lifting capacity is required. As the trunk rope was pulled up, the rope was tightly stretched, and the trunk rope was stretched, which was dangerous to the work related to the breeding department, but the variable mooring facilities for aquaculture of each embodiment of the present invention are all Even if the lifting work is not performed, the necessary parts such as the breeding part surface and the support part, the mooring line, and the leash are loosened, so that the necessary work after the surface can be safely and easily performed.

図11は実施の形態2の養殖用水深可変係留施設の育成部などを避難させる時の状態を示す一部省略模式正面図である。
図11中、28は碇綱27と係留索25を繋いで水中に残すための繋ぎ索、28Aは繋ぎ索28に取付けられた繋ぎ索フロート、28aは繋ぎ索28の両端部に形成され係留索25や碇綱27の端部が連結される連結用アイ等の連結部、29は作業船係留部、29Aは作業船係留索、29Bは作業船係留固定部である。

(Embodiment 8)
The aquaculture water depth variable mooring facility according to the eighth embodiment of the present invention will be described below with reference to the drawings. In addition, the same code | symbol is attached | subjected to the thing similar to Embodiment 1 thru | or 7, and description is abbreviate | omitted.
FIG. 17 is a schematic plan view of the aquaculture water depth variable mooring facility according to the eighth embodiment.
In FIG. 17, 100 is a stationary net, the following are each part of the stationary net 100, 101 is a body net made up of a playground or a box net, 102 is an edge through which fish enters, 103 is a fence net, 103A is a fence net 103 from both sides A fixing rope 104 to be fixed, a rope 104 connected to the fence net 103 and a soil to fix the end of the fixing rope 103A to the bottom of the water, and 105 a float disposed at an important point of the fence net 103 or the fixing rope 103A. It is.

図17には、定置網漁場に張り建てられた定置網100の周囲に、実施の形態5の養殖用水深可変係留施設41が、誘導部として設置された状態が示されている。
定置網100に対して、垣網103の左側には、沖から灘に向けて配設される沖垣網に代わる誘導部として、複数の養殖用水深可変係留施設41が、垣網103と略平行に所定間隔で設置され、垣網103の右側には、右側や灘側から来遊する魚群に対する誘導部として、複数の養殖用水深可変係留施設41が、垣網103と直角方向や斜め方向にかけて設置されており、定置網100を固定するための土俵が一部の養殖用水深可変係留施設41の碇綱固定部26として利用されている。
定置網100は、網周辺に来遊する魚群を端口102から身網101内に誘導して漁獲するが、沖側を通過する魚群や、端口102に向かわない魚群は漁獲されずに他へ移動すると見られている。定置網100の周辺に来遊した魚群の内、端口102に向かわない魚群は端口102に向かう魚群より多いという魚群行動観察があり、身網101の沖側を通過する魚群を遮断する目的で沖垣網が設置される事例がみられ、一定の評価を得ている。
実施の形態8の養殖用水深可変係留施設41は、魚群を遮断するだけではなく、来遊する魚群を定置網100に誘い込む誘導部として設置され、各々が、碇綱固定部26、水深と同じ位の水平距離間に配設された碇綱27、水深の2〜5倍程度の長さの支持部43、水深と同じ位の水平距離間に配設された係留索45、引き込み用フロート8の順で構成されて設置されている。図13に示されたように、支持部43の配設箇所には第二支持部43A,補助支持部43B,浮上用フロート44,補助支持部43Bに取付けられた多数の育成部42が配設されており、引き込み用フロート8の配設箇所には固定部6に取付けられた方向転換具7が配設されて係留され、上層から底層までを遮蔽した状態で設置されている。
実施の形態8の養殖用可変係留施設41は、資源培養的役割と魚群誘導の役割を有し、育成中の海藻類の繁茂、餌料、残餌、排泄物の排出や拡散によって、植物プランクトン、動物プランクトンが発生し、稚魚、小魚などが集まり、それらを捕食する目的で来遊する魚群を所要の場所に誘導又は蝟集させ、魚群の日周行動や対網行動を利用して、定置網の入口である端口102に誘い込んで定置網100で漁獲するという、機能的な魚群誘導によって定置網漁獲量の増大を図ることができる。
定置網100の周辺に係留された、各養殖用水深可変係留施設41は魚介藻類の育成や養殖に供されて本来の育成目的生物が生産されるが、定置網の漁業権の範囲内や周辺での養殖業着業によって、沿岸域に多数設置されている定置網の周辺での養殖漁場が広がり、漁場の有効利用が図れ、これによって、漁場競合や密殖が防止され、定置網漁業との兼業による効率的な操業、経営ができ、生産量増大を図ることができる。
ここで、定置網100の誘導部としての養殖用水深可変係留施設41は、魚介藻類全般に用いられるが、コンブなどの海藻類を養殖する施設の設置によって海の森が形成でき、
プランクトン、稚魚、小魚が集まり、定置網の漁獲対象となる魚群が来遊することが期待されるとともに、酸素の供給や漁場浄化にも効果が期待できる。
尚、定置網周辺には、実施の形態5の養殖用水深可変養殖施設41に限定されず、本考案の養殖用水深可変係留施設を、目的、地形、水深に応じて設置することができる。
